GEOLOGY Abnormal radioactivity occurs along a N80W vertical fault in slightly bleached, iron-stained metaandesite of probable Mesozoic age. A 2-inch-wide gouge zone is the most radioactive. Other less radioactive spots were noted within the surrounding nearby area. Autunite was recognized, but does not account for all of the radioactivity. One skarn specimen was quite radioactive, but contained only minor autunite. The area lies quite near the contact with a granitic intrusive. Meta-autunite is present on skarn. Stream placers near Carson City have yielded as much as 12 pounds per ton of heavy concentrates, most of which consisted of magnetite. However, chromite, garnet, zircon, monazite, and gold also were present. In two concentrates, monazite is reported to make up 5 and 29 pounds per ton, zircon 80 and 21 pounds per ton, and gold $8.78 and $7.44 per ton respectively. The 5-pound-per-ton sample was known to be a concentrate of a 12-pound-per-ton separate, giving known concentrations in the stream placers of 0.03 pounds per ton of monazite (0.000015%), 0.48 pounds per ton zircon (0.00024%), and 0.000025 ounces per ton gold. Anomalous radioactivity is associated with northerly-trending fractures in Oligocene(?) ash-flow tuff. The fractures dip 80E. Meta-autunite is present on skarn. Autunite and limonite reportedly occur in a slightly brecciated and kaolinized area in Oligocene ash-flow tuff. Similar mineralization is reported from the base of the tuff section, where it contains a few feet of sediments and overlies granitic rocks. Meta-autunite also reported in the ash-flow tuff. The Sally No.3 was found in 1969 in the SW SE Sec. 16, T15N, R21E, but the radioactive area could not be located. Slight radioactivity was found along a nearly vertical 2- to 5-foot-wide pegmatite dike which trends N40E. A nearby parallel dike is also radioactive. The dikes cut Mesozoic schists and phyllites, and are composed mainly of quartz and feldspar with some magnetite-rich areas. No zoning was noted, but the central portion of the dike is slightly more radioactive. Organic-rich spring muck contains anomalous amounts of uranium An unidentified yellow uranium mineral occurs in a small quartz vein with iron and copper sulfides. The wallrock is unknown, but Sections 13 and 24 are mostly underlain by Cretaceous granodiorite. The prospect could not be located in 1969. Irregular veins, containing silver and lead minerals, occur in Triassic(?) carbonate rocks. The ore minerals include cerussite, anglesite, cerargyrite, wulfenite, vanadinite, and argentiferous galena. Anomalous radioactivity was noted on the 335-foot level, associated with a gouge zone in a radioactivity was noted on the 335-foot level, associated with a gouge zone in a dolomitized limestone. Concentrations of nickel and cobalt occur in small veinlets along a sheared contact between fine-grained gabbro and albitized Jurassic arenite. Primary and oxidized nickel, cobalt, and copper minerals have been recognized. The arenite is commonly highly folded and fractured, and often intruded by fine-grained albitites. Albitization and silicification of the arenite is commonplace. Positive sodium fluoride bead tests for uranium were obtained on several distinct minerals from mill slag samples. A sample submitted to the Atomic Energy Commission in 1951 contained 0.335% eU3O8, and was identified as pitchblende in ferromagnesium minerals. The deposits have recently (Lutz and Hulen, 2002) been interpreted as exhalative and stringer mineralization contemporaneous with volcanic rocks of the Humboldt igneous complex. Zeunerite occurs as lustrous, green, tabular crystals up to 1 mm long with lavendulan in the Nickel Mine. Fireball Ridge consists of a pre-Tertiary sequence of schistose and phyllitic metavolcanic pyroclastic(?) rocks overlain by a sequence of phyllite and slate and intruded by a quartz diorite to gabbroic pluton. Quartz veins, one massive calcite vein, and iron-stained shear zones cut pre-Tertiary rocks around the margins of the plutons, but the metallic mineralization appears marginal. The shaft is near the contact of Triassic-Jurassic(?) propylitically altered, olive to light gray schist and the Cretaceous(?) granodiorite intruding it. Gold and uranium are noted as commodities in the U.S. Bureau of Mines (1995) MASMILS database. Uranium is reported present in a 10-foot interval in Tertiary sedimentary rocks containing 50% lignitic units. One bed averages 3.5 feet thick and contains up to 0.06% uranium (up to 0.1% in the ash). Dips are low in the surrounding poorly indurated sandstones and shales, and exposures of the radioactive units continue for more than a quarter of a mile. The ash content of the lignite ranges from 59 to 75%. Selenite is commonly present in the lignites. Anomalous radioactivity reportedly occurs in rhyolitic flows.

Two small allanite pegmatite bodies are known in the Gold Butte area. They are generally small irregular bodies in porphyritic rapakivi-like granite. Volborth (1962a) reports that all known allanite pegmatites occur near the contacts between Precambrian granites and schists. Allanite is concentrated in poorly developed wall and intermediate pegmatite zones, which are mostly composed of very coarse-grained microperthite and quartz. Biotite and, in one case, magnetite are abundant associates. Allanite does not exceed 1 to 3% in these zones of the pegmatites, and only traces of zircon and samarskite are present. Allanite (replacing plagioclase), limonite, hematite, zircon, thorite, monazite and an unidentified rareearth phase were reported in addition to apatite, quartz, and plagioclase. Area is underlain by Precambrian gneiss displaced by faulting and locally invaded by Tertiary intrusive rock. The gneiss is coarse-grained and consists of alternating bands of granular and schistose minerals. The mineralization consists of a dark brownish-black waxy filling in fractures and porosity between crystals. This material was not identified. 1-foot-thick shale bed near the middle of an 8- to 10-foot-thick limestone unit of the Tertiary Horse Spring Formation(?) is anomalously radioactive at several localities.

The lead-zinc ore occurs in tabular bodies which plunge 30 to 60 SE in the Mississippian Monte Cristo Limestone. Ore is localized along brecciated fault intersections. Hydrozincite is the predominant ore mineral, but calamine, smithsonite, galena, cerussite, and anglesite are also present. Primary uranium minerals may be present at depth in the unoxidized ore.

The calcrete is buried by recent alluvium in lower Hidden Valley, where more occurrences might be buried. Anomalous radioactivity is reportedly associated with limonite and oxidized copper minerals. The workings explore a shear zone in the Sultan Limestone that contains oxidized copper and cobalt minerals. A small amount of chalcocite is present, but the most abundant material is a mixture of chrysocolla, tenorite, malachite, and cobalt oxide in a siliceous iron-oxide gangue. Veins and lenses of chalcopyrite and a cobalt sulfide may have made up the original ore. A lenticular quartz-feldspar pegmatite body that trends north and dips steeply to the east cuts a coarsegrained porphyritic granite. The pegmatite is 30 feet wide and is exposed for more than 180 feet. Samarskite (or euxenite) occurs as distinct masses which are sparsely and irregularly distributed in the dike. Other minerals include monazite(?), purple fluorite, epidote, clinozoisite, muscovite, biotite, magnetite, stibiotantalite(?), and chlorite(?).

Carnotite is found in northwest-striking, southwest-dipping joints in a gypsiferous zone in the Tertiary Horse Spring Formation. The gypsiferous zone was interpreted as a bedding-plane fault. The mineralized beds are gypsiferous limestone and calcareous sandstone. Carnotite and opal fill joints and fractures in steeply dipping silicic and calcareous sediments of the Triassic Chinle(?) Formation. Hydrothermal alteration is reported. Carnotite occurs as small patches and films on sandstone and limestone of the Permian Toroweap Formation. Visible carnotite is not abundant enough to produce high radioactivity. Water from a pool at the bottom of a 100-foot-deep shaft contained 4.9 micromicrocuries per liter of radium and 110 micrograms per liter of uranium. Shales, limestones, and tuffs of the Triassic Moenkopi Formation cut by a granite porphyry dike are reported present in the shaft. The radium probably indicates the presence of volcanic or intrusive igneous rock. Radioactivity is localized in limonite and oxidized copper minerals.

Uraninite was reported as inclusions in zenotime, and a Ce-La mineral (basnasite?) is found locally as inclusions(?) in zircon. An allanite-like mineral has been reported from an aplitic dike that cuts Precambrian rocks near the Neppeno mine northwest of Crescent Peak. Radioactivity reported from this area may be due to the allanite. Carnotite occurs along bedding and fractures in a red sandstone of the Permian Supai(?) Formation.

Interbedded peat, clay, and sand in a bog up to 4.6 m thick. Most sediment appears to be post-Mazama (6,700 BP). Springs appear to be the source of the uranium, which is likely derived from the bedrock which is Cretaceous hornblende quartz monzonite and monzogranite. An airborne radioactive anomaly is reported from this area. The rocks in the area are andesite flows and intermediate-composition ash-flow tuffs. No anomalous radioactivity could be found in 1979, and no prospect pits were observed. An airborne radiometric anomaly was noted to the east of Mountain City, but the bedrock there was covered with alluvium, and no evaluation could be made. Bedrock is probably Tertiary Jarbidge Rhyolite An area of rhyolite flows is anomalously radioactive over a considerable area. A locality having five times the background radioactivity was noted during ground reconnaissance. This anomaly is almost certainly on the north end of a large mass of highly radioactive topaz rhyolite (Price and others, 1992). See Toanano Range Rhyolite description. An asphaltic pyrobitumen (probably impsonite or grahamite) has been reported from several localities between Trout Creek and Willow Creek, near the Eureka County line. The occurrences are reportedly associated with a north-trending basin-and-range fault. At the best described locality, the impsonite(?) occurs in lenses, stringers, and sheets along a fractured zone about 3 feet wide. The veins cut sandstone, shale, and conglomerate of the Diamond Peak Fm.-Chainman Shale, and range from pure lenses up to 18 inches wide to asphalt impregnated sandstone. The vein which follows the fracture zone trends N60E and is nearly vertical. Samples of the impsonite(?) are said to resemble coal and have a specific gravity of 1.9, a pitch-like luster, and conchoidal fracture. Vanadium and uranium are both present in anomalous amounts. The vanadium is present almost exclusively in the impsonite?, as shown by the ash analyses below (Vanderburg, 1938). Original sample 0.16% V2O5. Ash and impurities 6.4. Minus 20-mesh ash 24.8.

Autunite, torbernite, and meta-torbernite are present along an altered and silicified fracture zone in Cretaceous quartz monzonite. The mineralized zone strikes N12W, is nearly vertical, and contains minor amounts of quartz, molybdenum, and iron oxides. A nearby molybdenum prospect contains pyrite and molybdenite in quartz veins and disseminations in the quartz monzonite. Autunite is reported along a north-trending vertical fault which forms the west contact of a 2.5- to 3-footthick, beryl-bearing pegmatite dike.

Copper skarn mineralization is developed in the carbonate rocks. Anomalous radioactivity is associated with limonite, which was probably derived by oxidation of pyrite and other sulfide minerals. Latite-dacite dikes also cut the carbonate rocks. The stock is anomalous in uranium (5.4 ppm U3O8). Strongly silicified tuffs and sandstone in the Miocene Humboldt Formation. Eleven parallel, north-striking pegmatite dikes cut quartzite and schist. Dikes dip 40E to vertical. Pegmatite dikes contain 10-20% mica as sheets and books and beryl crystals up to 3 inches in diameter. Pegmatite dikes are zoned and consist of plagioclase, quartz, muscovite, perthite garnet, beryl, microcline, apatite, zircon, hematite, biotite, phlogopite, tourmaline, and penninite. The three largest pegmatite bodies are up to 11 feet thick and 350 feet long. Uraninite occurs along a fault that strikes N75W and dips 65E in a body of tactite. The uranium occurrence is reported to be 295 feet from the portal of one adit. The tactite has replaced limestone along the contact of a granite stock with the Cambrian or Ordovician Tennessee Mountain Formation. Pyrite, molybdenite, bismuthinite, and minor chalcopyrite occur with finely disseminated scheelite. Exploration work was done for tungsten. 1963: W reserves: 224,000 tons at 0.5% WO3, 540,000 tons at 0.4% WO3. A small piece of uraninite and its alteration products was reportedly found near an 8-foot-wide quartz mass forming the core of a larger pegmatite body. Beryl, columbite-tantalite, and garnet were also found. Monazite-bearing placer gravels reported. Minor placer gold deposits worked along the "north fork" of the Bruneau River near Rowland. Radioactivity reportedly occurs in Tertiary rhyolites and tuffs. The geology may be similar to that at Happy Joe No.1, etc. Radioactivity reportedly occurs in rhyolites and tuffs mostly in the Miocene Danger Point Tuff. The geology may be similar to that at Happy Joe No.1, etc. Anomalous radioactivity with minor autunite occurs in Tertiary volcanic rocks near the contact with underlying quartz monzonite. The volcanic unit is the Cougar Point Welded Tuff. The occurrence appears to localized in depressions in the quartz monzonite which have been filled with Tertiary ash falls, pumice flows, and pumice flow breccias. Autunite occurs in fault zones in rhyolite. The anomalous radioactivity extends for at least half a mile along the structure and a branching structure. Tuff is mostly the Miocene Danger Point Tuff and some Miocene Phenorhyolite of Cold Springs Mountain. Autunite occurs in conglomerate and rhyolite ash-flow of the Oligocene Tuff of Harris Gulch overlying quartz monzonite. Radioactivity and minor autunite occur along the contact of volcanic rocks with underlying quartz monzonite. The volcanic rocks are mostly rhyolite ash-flow of the Oligocene Tuff of Harris Gulch. The host for the uranium mineralization is arkosic sandstone, conglomerate, and air-fall tuffs deposited in a paleovalley developed on quartz monzonite. Autunite occurs along a fault which separates granodiorite from the pyroxene andesite of Russell Gulch (Coats, 1968). The uranium mineralization is in a 2.5-foot-wide zone, and is associated with clay minerals. Uranium concentrated along a weakly silicified sandstone-limestone contact and in a pebble conglomerate. Sedimentary units strike northeast and dip gently southeast. Anomalous radioactivity occurs in oxidized copper-bearing veins which cut a Cretaceous(?) granodiorite. Most of the claims are over Cretaceous granitic rock. The northernmost claims partly cover Oligocene Tuff of Harris Gulch. Very weak radioactivity is reportedly associated with clays, gypsum, and weak iron staining in lake sediments of the upper Tertiary and lower Quaternary Hay Ranch Fm. The anomaly may be due to radioactivity differences between alluvium and Tertiary sediments. Two carbonaceous shale beds in the Salt Lake Formation having an aggregate thickness of 9 feet contain slightly anomalous amounts of uranium. A measured section in the Tertiary Salt Lake Formation at this locality includes 5 feet of carbonaceous shale which contains slightly anomalous amounts of uranium. Monazite-bearing placer gravels reported. Small placer deposits mined in Lost Gulch, Slate Creek, and Tennessee Gulch. Uranium mineralization has been reported from opalized volcanic beds. Claims for uranium were staked in this area in the 1950s, according to Elko County claim records. However, no radioactive localities could be found during a 1978 visit. Monazite-bearing placer gravels reported. According to Carper (1945), two pans of gravel gave a large sample of black sand which contained 27% magnetite and 73% nonmagnetitic material with 1-2% monazite and a trace of cinnabar. The source of the gravel is granitic rocks. Radioactivity reportedly occurs in rhyolites and tuffs mostly in the Miocene Danger Point Tuff. The geology may be similar to that at Happy Joe No.1, etc. Autunite and meta-autunite have been reported from a fault zone in limestone(?). Anomalous radioactivity is associated with limonite and hematite staining and silicification in Late Miocene tuffaceous fluvial and lacustrine sandstones and shales. Uranium mineralization occurs along bedding in Tertiary tuffaceous lake sediments. Peterson (1956) reports a uranium occurrence east of Contact which may be related to a lineation (fault?) separating Tertiary sedimentary and rhyolitic volcanic rocks. Radioactivity reportedly occurs in rhyolites and tuffs mostly in the Miocene Danger Point Tuff. The geology may be similar to that at Happy Joe No.1, etc. Slight radioactivity was reportedly found in shear zones in rhyolite flows and in a Cretaceous coarsegrained quartz monzonite stock, and in fractures in several northeast-trending, orthoclase pegmatite dikes. Also, various areas along the contact of the quartz monzonite stock with Carboniferous shales and limestones were radioactive. In one area the uranium mineralization is associated with chrysocolla and iron oxides. Thorium accounts for most of the radioactivity. Snow (1963) did not find any uranium mineralization during detailed mapping of this area. Anomalous radioactivity and uranium mineral occurrences are present along fault zones in Permian(?) limestone and sandstone. Uranophane, renardite, phosphuranylite, and coffinite(?) were recognized at one locality; however, elsewhere uraniferous limonite-maghemite is the main radioactive species. Four radioactive localities are reported in a 0.5 square mile area, associated with northeast- or northwesttrending fault zones which are hydrothermally altered and leached. The mineralization has not been investigated at depth. Two alternate hypotheses have been proposed to explain the mineralization: (1) uranium was leached from tuffaceous and arkosic conglomeratic sedimentary rocks of the Mio-Pliocene Idavada Fm. or from the granitic and volcanic source-rocks for this unit. In this model, uranium would be deposited from uranium-bearing groundwater along fault zones in limestone and quartzite, either precipitated on amorphous iron-oxides or coprecipitated with the iron oxide minerals. (2) An alternative hypothesis is that the radioactive occurrences are oxidized portions of hypogene veins, probably of simple mineralogy (pyrite-uraninite?). Anomalous radioactivity occurs along a shear zone separating Tertiary volcanic rocks from Cretaceous quartz monzonite. The radioactivity was discernable for more than 200 feet along a 15-foot-wide zone. Mineralization was probably controlled by a low or channel which directed uranium-bearing water through carbonaceous devitrified tuff (clay). Later, remobilization or precipitation of uranium occurred when faulting provided new zones of porosity and maybe isolated the channel(?) from its original hydraulic system. Most of the minerals are autunite, which is disseminated along the shear zones. Torbernite and meta-torbernite were also reported. Autunite is reported from Tertiary arkosic sedimentary rocks and ash-flow and airfall tuffs that were deposited in a paleochannel in Cretaceous quartz monzonite. Anomalous radioactivity is associated with oxidized copper-bearing veins in Carboniferous limestone and Cretaceous(?) granodiorite. Autunite and minor uraninite, carnotite, torbernite, and renardite occur in fractures and with pyritiferous coalified wood at the base of a sequence of andesitic and dacitic welded tuffs. The deposit is localized in fluvial channels and depressions cut in Cretaceous quartz monzonite which underlies the welded tuffs. The fluvial rocks which fill these depressions are arkosic, conglomeratic granite wash and montmorillonitic tuff and tuff-breccia. Mineralized rock is bleached and hematite-stained, and reaches a maximum thickness of 80 feet; grades exceed 2% in some thin zones. Vanadium, zinc, copper, molybdenum, nickel, and cobalt are anomalously abundant. Post mineral normal faults have modified some deposits. The possible source rocks include the Cretaceous quartz monzonite and Tertiary volcanic rocks. Uraniferous solutions may have migrated along the quartz monzonite-volcaniclastic rock nonconformity and deposited uranium by reduction near carbonaceous material or by adsorption on montmorillonite. Radioactivity is present along more than 400 feet of exposed contact of the Cretaceous Mountain City quartz monzonite stock with the basal zone of a rhyolitic air-fall tuff below a black, vitrophyric, andesitic welded tuff called the pyroxene andesite of Russell Gulch (Eocene or older). Autunite is concentrated in a 2- to 3-inch-thick bentonitic zone just above a thin charcoal layer. Weaker uranium mineralization extends downward to the weathered quartz monzonite 1 foot below, and for over 1 foot above, into the unwelded basal zone of the tuff. A carbonized log with minor autunite was reported from 60 feet underground. In 1968 the Lucky Strike No. 0 claim was located near the road along California Creek (L.J. Garside, unpub. data). The travertine mound at this warm (54C) spring is anomalously radioactive (4-25 times background), but contained only 4 ppm U3O8. A topaz rhyolite intrusion that crops out over nearly 25 km2 contains anomalous amounts of U (46 ppm) and Th (87 ppm). A much smaller body is exposed about 2 km east of the main mass, in Sec. 4, T37N, R68E. The rhyolite bodies have been detected in airborne radioactivity surveys. They contain very smoky quartz, which probably owes its darkening to radiation damage. Claims are mostly over biotite-hypersthene pheonodacite tuff of the Oligocene(?) Bieroth Andesite of Bushnell (1967). Anomalous radioactivity and uranium values are found in Paleozoic carbonate rocks that are silicated by an adjacent Jurassic(?) quartz monzonite stock. Copper skarn mineralization is developed in the carbonate rocks; gold mineralization is found locally. Uranium may be concentrated, in part, in limonite derived by oxidation of pyrite and other sulfide minerals. The stock is anomalous in uranium (5.4 ppm U3O8). Anomalous radioactivity is associated with limonite along high-angle shear zones in silicated and marbleized Paleozoic carbonate rocks. The adjacent Jurassic(?) quartz monzonite stock is anomalous in uranium (5.4 ppm U3O8). Sulfide minerals are rare, but limonite probably represent s their oxidized equivalent. Weak radioactivity occurs in opalized zones containing a little carbon trash. Iron and manganese oxides are present. The rocks are part of the lacustrine and fluviatile late Tertiary Humboldt Formation. Several uranium prospects have been reported along the southwestern border of the White Rock stock and along the arcuate fault separating the Porter Peak Limestone and Prospect Mountain Quartzite south of the intrusive contact (Decker, 1962). Abundant gossan is reported from the radioactive areas, but no uranium minerals were recognized. A small amount of radioactive (5-6 times background) gossan was noted on the dump of the Nevada Mine (NE Sec. 19, T44N, R52E; Garside, 1980). The Hot Rock claims (located 1954), located 1,500 feet northeast of the Nevada Zinc Mine could be for uranium (Elko County Recorders Files, Book 2, page 147). Slight radioactivity is reported from one prospect, which is located on a quartz vein cutting an altered tuff. Slight radioactivity reported from these claims may be associated with petrified wood in Tertiary sandstone and conglomerate. Very slight radioactivity has been reported from highly folded and brecciated limestone and shale(?) in the Ordovician Palmetto Formation. Abnormal radioactivity (reportedly 2 to 3 times background) occurs along vertical, north trending fractures in a Tertiary conglomerate. The conglomerate is well cemented with silica, and is fossiliferous. Anomalous radioactivity is reported from tuffaceous lakebeds of the Siebert Tuff. This locality could not be located in 1969 and 1970. Anomalous radioactivity occurs around a spring. The highest radioactivity was found over the spring itself, and in windblown sand nearby. However, areas of alluvium within 100 feet of the spring are up to two to three times background. Outcrops of Tertiary lacustrine mudstones and calcareous spring deposits are not radioactive. An older Tertiary quartz latite hypabyssal intrusion crops out in the vicinity, but no anomalous radioactivity was noted in this unit. Radioactivity may possibly be due to gammaemitting decay products of radon in the spring water. Uranium and anomalous radioactivity are associated with iron-oxide and clay minerals in brecciated areas that are near a apparent fault between Tertiary ash-flow tuff and lacustrine sedimentary rocks. An oxidized "iron dike" reportedly cuts limestone, and is radioactive along the footwall side. The limestone is probably in the Precambrian Wyman Formation. Uranium mineralization occurs in a rhyolitic welded tuff near a fault contact with younger Tertiary fluviatile and lacustrine rocks. A normal sedimentary contact is present just east of the prospect. The area of mineralization is 400 feet long and up to 200 feet wide. Uranium is irregularly disseminated in siliceous veinlets, in a siliceous breccia pipe, along limonite stained joint surfaces, and as incrustations and cavity fillings of autunite, meta-autunite, and phosphuranylite. Veinlets and limonite coatings contain up to 0.31% U3O8. Except for samples containing visible secondary uranium minerals, chemical assays are about 10 to 20% lower than radiometric analyses. Nearby lignite beds in the sedimentary rocks are not uraniferous. Copper, lead, and silver mineralization is reported from quartz veins which cut granitic intrusive rock. The anomalous radioactivity occurs in a pit where a 6-inch quartz vein is exposed. Radioactivity occurs sporadically along seams up to 6 inches thick in a series of interbedded tuffaceous and sandy lacustrine beds. The most intense radioactivity occurs along a 6-inch band of buff colored tuff in a medium-grained, well cemented sandstone. Autunite, meta-autunite, and an unidentified yellow earthy uranium mineral are scattered throughout the tuff for an exposed distance of 21 feet. The lakebeds strike N50E, dip 55SE, and appear to be interbedded with a series of massive lava flows. A prospect on the north slope of the Silver Peak Range is reportedly slightly radioactive. The workings are on a galena-bearing quartz vein. The radioactive area occurs in a gouge zone along the east (hanging wall) side of the vein. Most of Section 35 is underlain by the Cambrian Campito and Harkless Formations. A small spot of several square feet at the outlet of Gap Spring is slightly radioactive. The area surrounding the spring is lacustrine tufa deposit. The tufa itself is not usually radioactive, but an area of running water has the highest radioactivity. The water may contain radon, but no analysis was made. Autunite, meta-autunite, and minor carnotite are disseminated in lacustrine tuffs and poorly consolidated ferruginous sandstone. Anomalous radioactivity is reported in quartz veins which cut a granitic intrusive. Copper, lead, and zinc minerals are present. Anomalous radioactivity is associated with northeast or east-west-trending zones of narrow, chalcedonic veinlets and silicification in rhyolitic ash-flow tuffs. Most of these anomalous areas were apparently located and drilled, as they are adjacent to drill pads. The most prominent mineralized features are two sub-parallel veins with trends N60E and N80E, and are near vertical. There is no noticeable radioactivity associated with these veins, however, it is rumored that they are anomalous in Mo and possibly other elements. The veins are a combination of chalcedonic vein material and silicified rhyolite tuff (with narrow veinlets that parallel the zone). The chalcedony is white to black, or pinkish and locally contains iron- and manganese-oxide minerals. Near horizontal veins exhibit crustification textures. Some zones of pebble dikes (hydrothermal breccias with rounded fragments were observed in the vein zone. A veinlet of alunite(?) and a mineralized area containing an unidentified zeolite with radiating white crystals were found. Radioactivity is reported from gouge zones along faults in limestone of the Precambrian Wyman Formation. Iron oxides and copper carbonates are also present. A tabular body of iron oxides (mainly limonite) occurs along the east-trending, high-angle contact fault contact between chert of the Ordovician Palmetto Formation and dolomite of the Permian Diablo Formation. The iron oxide body is up to 100 feet wide and several hundred feet long. A porphyritic quartz monzonite intrudes the chert within a few hundred feet of the prospect. Radioactivity occurs at several spots in the iron oxide body. This body is most likely a gossan produced by the oxidation of pyrite or other sulfides. Anomalous radioactivity detected during an airborne radiometric survey. The SW of Sec. 10 is underlain by the Ordovician Palmetto Formation, and most of the rest of the W of Sec. 10 and the E of Sec. 9 is underlain by Cambrian Mule Spring Limestone. Anomalous radioactivity and iron staining reportedly occur along minor fractures in Tertiary rhyolites and tuffs. Utron No. 3 was examined in 1970, but no radioactivity was found. The six radioactive localities described above all fall on a line which trends N25E. Several occurrences are related to north-trending faults, and isoradioactivity anomalies are elongated in a north-south direction. Davis and Hetland (1956) mention that the uranium present is contained in collophanite. Samples containing up to 27% P205 have been reported. Numerous exploration holes were drilled in the 1950's and logged by the Atomic Energy Commission. These holes show anomalous radioactivity to depths of 100 feet, the deepest drilled; fine, diagenetic(?) pyrite is present at depth. The most anomalous radioactivity is within 40 feet of the surface. Uranium mineralization may be localized by certain beds, or may occur in several different beds along minor, iron-stained fractures. These fractures nearly always trend north or northeast. Two samples from locality SU-2 contained 374 ppm and 166 ppm of molybdenum, about 20 to 30 times normal vanadium is reportedly present only in amounts normal for rocks of this type. Most of S/2 of section 29 and most of section 32 are underlain by Miocene Siebert Tuff. See description for Locality SU-1 See description for Locality SU-1 See description for Locality SU-1 Four radioactive occurrences lie along a line that trends N15W. At two localities (SU-5 and U-6), a N10W, 55-60W fault was present. No faults could be identified at U- 7 and U-8 but they may be present. At locality U-6, the radioactivity is associated with certain iron-stained tuffs and tuffaceous shales in the footwall of a N10W fault. A sample from U- 7 contained 117 ppm molybdenum. Most of S of Sec. 29 and most of Sec. 32 are underlain by Miocene Siebert (Tuff) Formation. See description for Locality SU-1 Abnormal radioactivity at two of the four above localities (U-11 and U-25) is associated with minor faults that trend N25E. Additionally, possible north-trending fractures were present at U-12 and the anomaly at U-10 may also be related to unrecognized fractures. The trend of these four occurrences is also suggestive of a structure having this direction, but beds of the Siebert Tuff here strike about due north and dip 25W, and the radioactivity may be related to bedding. Iron oxides occur at both radioactive and non-radioactive localities, in the tuffs and tuffaceous shales. See description for Locality U-10 See description for Locality U-10 See description for Locality SU-1 Anomalous radioactivity occurs in tuffaceous shales, sandstones, and conglomerates. Some areas of higher radioactivity are associated with iron-stained fault zones. A N10W fault is present at locality U-15. Some areas of conglomerate exposure have a high background over several thousand square feet. Most of Sec. 32 is underlain by Miocene Siebert (Tuff) Formation. See description for Locality U-14a See description for Locality U-14a See description for Locality U-14a Anomalous radioactivity is concentrated in iron-stained tuffaceous shales and conglomeratic, tuffaceous sandstones. At two localities, the uranium seems to be associated with a certain bed or sequence of beds, (U-19 and U- 20), and at a third (U-21) the radioactivity is concentrated in the footwall of a fault that strikes N45E, and dips 60NW. Most of Sec.32 and the NE of Sec. 6 are underlain by Miocene Siebert (Tuff) Formation. See description for Locality U-19 See description for Locality U-19 An area of 10 to 20 square feet in iron-stained tuffs is radioactive. A fault that strikes N17E, and dips 75W was reportedly radioactive at this locality. The fault could not be located 1969, but this locality is one of several on a N25E trend of occurrences. Most of S of Section 29 and most of Section 32 are underlain by Miocene Siebert (Tuff) Formation. See description for Locality U-10 See description for Locality SU-5 See description for Locality SU-5 See description for Locality SU-5 Workings follow an E-W fault zone which curves N45W towards the west. The fault zone ranges from approximately 8 inches wide in the east to over 3 feet at the west end of the workings. The host rock is the Precambrian Wyman Formation, thinly bedded mud/siltstone which has been metamorphosed locally into spotted phyllites. The rocks are highly fractured and heavily iron oxide stained. No vein was observed in outcrop, however the dumps were composed of calcite and quartz vein material, both of which were highly brecciated, cemented with limonite stained silica, and carried oxidized pyrite grains. The fault zone was argillically altered. An unknown uranium mineral was reported. Radioactivity is reported from along the contact of a rhyolite and a tuff. Iron stained quartz stringers are associated. The prospect could not be found in 1970. Radioactive ore with vanadium has been reported from the Mohawk property in western Esmeralda County. Gold and lead were also reported. There is a Mohawk mine in the Argentite mining district (NE Sec. 36, T2S, R38E); it is not known whether this is the property containing the radioactive ore. This mine is in Pliocene Latite of Sheep Mountain. Uranium mineralization (carnotite?) occurs along a shear zone and along bedding planes in fluviolacustrine sediments of the Tertiary Esmeralda Formation. The sediments consist of partially silicified, carbonaceous mudstone units separated by conglomerates. The uranium occurs in the mudstone units. A few small spots in a Tertiary bentonitic conglomerate are slightly radioactive. The conglomerate may be near the base of a Tertiary clastic section, which here overlies the Ordovician Palmetto Formation. The Tertiary sedimentary rocks in this vicinity were apparently deposited on a surface of high relief. No uranium minerals were noted during a visit in 1970. Autunite(?) occurs along a fault exposed in a 15-foot-deep shaft. The wall rock is reportedly shale (Precambrian Wyman Formation). The presence of uranium has been reported at this mine. No other information is available. Section 22 is mostly underlain by Jurassic Granitic Rocks of Sylvia Mountains Pluton which is locally covered by Quaternary and/or Tertiary basalt. Description included with that for Coaldale prospect. A kaolinized shear zone in an adit is abnormally radioactive over a 0.5 to 1 foot width. This radioactive zone parallels the drift for 20 feet, at a distance of about 180 feet from the portal. Autunite(?) and metaautunite were reported. The wall rock is quartz monzonite, and workings follow northwesterly trending shear zones. Autunite, azurite, malachite, meta-autunite, siderite, and iron oxides occur along a highly brecciated shear zone in limestone of the Precambrian Wyman Formation. Rameauite occurs as yellow coatings on rhyolite. Abnormal radioactivity occurs in isolated pods and stringers along the contacts of a quartz-rich pegmatite dike which cuts Jurassic(?) granitic rocks. The radioactive pods occur in the country rock along both sides of the dike, but the dike itself is barren. Biotite, lepidolite, quartz, and orthoclase were identified in the dike. Very slightly anomalous radioactivity occurs along bedding planes in a series of well-bedded calcareous, lacustrine tuffs(?). The beds strike N80W and dips 45SW. Reported "estimates" in 1954 of the values per cubic yard in the heavy mineral fraction of 15 million cubic yards of gravel were as follows: gold, 12 cents; tungsten minerals, 6 cents; fluorite, 6 cents; uranothorite(?), 3 cents; monazite and xenotime, 3 cents; columbite and euxenite 1.5 cents; zircon and rutile, 1.5 cents. (Total = 33 cents). Placer mined along the upper 4 miles of the canyon. Euxenite reported with uranothorite, xenotime, and columbite. A small area (2 square feet) of anomalous radioactivity is associated with a 2-foot-wide quartz vein. The radioactivity is associated with limonitic patches in the country rock (granite?) adjacent to the vein. Cinnabar(?) also was reported. The outcrops in Section 22 are mostly Jurassic Granitic Rocks of Sylvia Mountains Pluton Hot springs along the edge of Clayton Valley dry lake are reportedly radioactive. Geology: Anomalous radioactivity occurs along a northeast-trending fault in metamorphosed sedimentary rocks. At the prospect the fault strikes N70E, and dips 60NW. The fault zone is from 6 inches to 2 feet wide. A yellow, earthy uranium mineral occurs as coatings along joints and bedding planes in tuffaceous MioPliocene sedimentary rocks. These are usually described as part of the Esmeralda Formation. The uranium mineralization is apparently present near the contact of the sedimentary rocks with an underlying welded tuff and agglomerate. Oxidized copper minerals, principally chrysocolla, malachite, azurite, and cuprite, occur along shear zones in chert, shale, and limestone units which are partially equivalent to the Ordovician Vinini Formation. The ore bearing zone strikes N60E and dips steeply northwest. The radioactivity is reportedly associated with secondary copper minerals along a N45E, 70W fracture. In brecciated jasperoid, tyuyamunite occurs as bright-yellow clots with kingite, thin powdery coatings associated with phosphate minerals, and relatively abundant pale yellow dustings on kazakhstanite and fervanite. Metatyuyamunite occurs as a dull, yellow-brown dehydration product after bright yellow tyuyamunite. Deep-green torbernite over time becomes pale-green metatorbernite. Uraninite occurs as grain up to 2 microns across in sulfide-rich barite breccia with galena, grenocktite, arsenopyrite, sphalerite, and pyrite. The host rock of the Gold Quarry deposit is Ordovician-Devonian chert, shale, siltstone, and impure carbonates, in part, Vinini Fm. Uraninite occurs as grains up to 2 microns disseminated in sulfide-rich barite breccia with galena, greenockite, arsenopyrite, sphalerite, and pyrite. Also present is torbnerite in grass green tabular crystals in up to 2 mm clusters with fluellite, hewettite, leucophosphite, variscite and anatase. Orebodies rich in silver, lead, and arsenic reportedly occurred along a vertical shear zone in the Ordovician Eureka Quartzite. Anomalous radioactivity is found in altered areas, probably associated with the shear zone. Brannerite occurs as grains 1 to 10 microns across with pyrite, apatite, and hydrothermal silica. The host rock is the Devonian Popovich and Roberts Mountains Formations. Anomalous radioactivity is associated with manganese oxide minerals in the Silurian Lone Mountain Dolomite. Anomalous zinc was also reported. Section 2 is underlain by "Quaternary older alluvium." Devonian Devils Gate Limestone outcrops in the Mahogany Hills over a mile to the east. The "east deposit" is exposed for a 40-acre area on the west slopes of Rock Spring Table and is in a series of discontinuous opal lenses in the Upper member of the Virgin Valley Fm. The lenses are from 0.1 to 4 feet thick and appear to be as mush as 300 feet long. All of the uranium appears to have been trapped in the opal. The "west deposit" is exposed for a distance of about 1 mile on the edge of a gravel-covered pediment and is in the Upper member of the Virgin Valley Fm. In a 20-foot-thick stratigraphic section, uranium was found in several 0.1 to 3.9-foot-thick opal beds interbedded with tuffs. Minor amounts of carnotite were found, but much of the uranium appears to have been trapped in the opal. Anomalous uranium values and slightly anomalous radioactivity is found in the vicinity of mercury prospects in welded ash-flow tuff. The uranium values are associated with iron-oxide minerals. This is apparently the prospect shown by Rytuba (1976, fig. 2) about 2 mi. southeast of Disaster Peak. Slight radioactivity reportedly occurs in tuffs and rhyolites. Iron oxides and opal are also present. Anomalous radioactivity occurs in an opalized tuff bed in the Virgin Valley Formation. See descriptions for Jack Crane claims and Lode Star Uranium claims. Anomalous radioactivity occurs in an opalized tuff bed in the Virgin Valley Formation. See descriptions for Jack Crane claims and Lode Star Uranium claims. Anomalous radioactivity occurs in an opalized tuff bed in the Virgin Valley Formation. See descriptions for Jack Crane claims and Lode Star Uranium claims. A uranium prospect was shown by (Rytuba, 1976, fig. 2) in this area. Castor and others (1982) reported uranium mineralization associated with iron oxides, silicification, and carbonate minerals in rhyolitic ashflow tuff. A trace of rutile and sulfides was observed. Anomalous radioactivity is reported from a thick sequence of flows, tuffs, and agglomerates. The radioactivity may in part be associated with charcoal material between flows or ash-flow tuffs. Iron and manganese oxides are also reported. Anomalous radioactivity (up to 0.3mR/hr) reportedly varies directly with secondary copper minerals. Chrysocolla, azurite, chalcocite, malachite, limonite, quartz, and torbernite(?) present are along 3- to 10foot-wide shear zone between silicified limestone(?) and a diorite. Silica veins cut buff to light purple, thin-bedded sandstone of probable Permian age and the basal vitrophyre of a rhyolitic ash-flow tuff sequence. Minerals include meta-autunite, brannerite, and weeksite. Thorite occurs as a uranium-bearing trace accessory in topaz rhyolite. Slight radioactivity is reported from volcaniclastic sedimentary rocks just above rhyolitic volcanic rocks. In 1976 uranium mineralization was encountered in drill holes along Horse Creek several miles north of the Moonlight Mine, in King's River Valley. The mineralization is associated with an extensive area of potassium feldspar alteration, and occurs in fractures and breccia zones in porphyritic, peralkaline rhyolite domes and hypabyssal intrusive rocks. These domes were emplaced along a probable ringfracture in the western part of the McDermitt caldera complex in the period from 14.0 to 13.7 Ma. A small volume ash-flow tuff associated with these domes is altered to potassium feldspar and quartz, reportedly contains up to 0.1% uranium. The main uranium mineralization at the Horse Creek occurrences is reported to be pyrite-uraninite; a number of other elements are anomalous, including Mo, F, Hg, As, Sb, Ba, Ag, Zr. Fluid inclusions in quartz from ore at the Moonlight Mine, related occurrences to the south indicate a deposition temperature of 330C, and stratigraphic evidence indicates that the Moonlight deposit formed at a shallow depth of about 2600 feet. Tonnage and grade figures have not been announced, although possible mill sites have been investigated by Chevron. Mo-porphyry mineralization was reportedly encountered in deep drill holes in the vicinity of the Moonlight Mine to the south. The McDermitt caldera complex is a Miocene collapse structure 27 miles in diameter. Large-volume rhyolitic and peralkaline ash-flow tuffs were erupted from 17.9-15.8 Ma, leading to the formation of overlapping and nested calderas. The rhyolitic ring domes are the last phase of the volcanic activity, and emplaced mainly along the west margin of the complex about 14-14 Ma. The complex is the site of large Hg deposits, an ore deposit and several occurrences of uranium and, and widespread occurrences of lithium. Uranium exploration activity has been concentrated in the vicinity of the Moonlight Mine and Horse Creek occurrences, and to the north in the vicinity of the Bretz and Opalite Hg mines, near Cottonwood Creek in Oregon about 3 miles north of the Nevada state line. Hydrothermal alteration (clinoptilolite and, locally, potassium feldspar) is associated with anomalous concentrations of As, Sb, U, Be, and Hg in upper Tertiary sedimentary rocks. A 1979 examination of the area did not find any anomalous radioactivity (L.J. Garside, unpubl. data). Slightly anomalous uranium was found at a turquoise prospect. A radioactive locality is reported from a small roof pendant of Happy Creek Volcanic Series in Duffer Peak Granodiorite, as well as in the main mass of the Happy Creek Volcanic Series just to the south of the granodiorite-volcanic series contact (fault? contact). A nearby spring is also reportedly radioactive. A variety of secondary uranium minerals, including uranyl phosphates, arsenates, and silicates are reported; coffinite was tentatively identified. A breccia of black shale clasts with pyrite contained 0.11% U3O8. Anomalous radioactivity occurs in clay-altered air-fall tuff and overlying ash-flow tuff (Soldier Meadows Tuff). Four small anomalies having slight radioactivity were reported at the south end of the main fault, which trends north-south and dips 40-60E. This radioactivity appears to be associated with pyrite or marcasite mineralization in the Cambrian Preble Formation. Sheet-like gold orebodies with abundant arsenic sulfide are localized along the main fault. A sample of phyllite from the east wall of the south pit contained ilsemmanite and autunite(?), and meta-autunite also occurs there with ilsemmanite and pascoite. This spring and its deposits are reported to be moderately radioactive. The water reportedly contains a few parts per million of thorium (oral commun., D. I. Segerstrom). A rhyolitic unit, which reportedly contains individual flows up to 150 feet thick, has a background that is 3 to 4 times the radioactivity commonly found in basin-and-range rhyolites. Surrounding rocks give readings of 0.035 mR/hr while the rhyolite averages 0.1 mR/hr. The rhyolitic unit may be peralkaline ashflow tuff. Anomalous trace elements are similar to those at the Moonlight Mine. Anomalous radioactivity occurs in an opalized tuff bed in the Virgin Valley Formation. See descriptions for Jack Crane claims and Lode Star Uranium claims. Mixture of rhyolite and possibly andesite(?), with white quartz veins in fault structures. Pyrite on wall rock. Carnotite is found as fracture coatings in dark, carbonaceous shale of the Ordovician Vinini Formation. Quartz stringers are present, but the carnotite was interpreted to have been leached from overlying tuffs. Anomalous radioactivity and secondary uranium minerals (carnotite and schroeckingertie?) are reportedly associated with opalized units in a sequence of fine-grained lacustrine tuffs in the middle Miocene (Merriam, 1911, p. 208) Virgin Valley beds. Carnotite commonly occurs as fracture coatings or as thin layers in the opal. The uraniferous opal is in discontinuous layers, as much as 6 feet thick and half a mile long, that are parallel to the bedding of the ash and tuff (Staatz and Bauer, 1954b). More than a third of the opalized beds examined were radioactive. The opal may be gray, brown, tan, black, white, and pale green, and may be banded or variegated. The pale green variety apparently contains the most uranium. Opalized fossil wood was noted in some areas. Basalt cap over rhyolite tuff and breccia. Slight radioactivity is present in a highly brecciated shale. Gypsum, quartz, and iron oxides are also present. The McDermitt Mine contains cinnabar and corderoite in argillically altered Tertiary sedimentary rocks which are caldera-fill sediments within the McDermitt caldera complex. Native mercury and mercury oxychlorites occur, but are uncommon. Strongly silicified rocks (opalite) are adjacent to the mercury ore. Fluid inclusion studies indicate a deposition temperature of 200C, at a depth of at least 500 feet. Uranium values up to 192 ppm are reported in the McDermitt zone of alteration (Garside, 1982b); apparently these values are for mineralization in the vicinity of Thacker Pass (Yellow Star prospect?) ~22 km to the southwest (J. Rytuba, oral commun., 1979). A minute amount of an unidentified uranium mineral was reported from the intrusive footwall rhyolite, which is exposed near the underground workings of the Cordero Mine (Fisk, 1968) adjacent to the open-pit McDermitt Mine. The uranium and mercury mineralization are believed to be related, and similar relationships are reported from the Bretz, Cottonwood Creek, and Opalite areas in Oregon, approximately 15 miles northwest of the McDermitt Mine. Uranium mineralization is found in rhyolitic ash-flow tuff associated with silicification, barite, apatite, and ilmenite. As, Sb, F, Hg, and Mo are anomalous. Uranium mineralization occurs in a silicified breccia zone in the hanging wall of a north-trending fault which displaces Tertiary rhyolitic ash-flow tuffs. The rhyolitic rocks overlie a Jurassic(?) quartz monzonite or granodiorite, which is present at depth in some of the workings. The mineralized fault dips from 45 to 54E near the surface, but the dip steepens to 60E in the inclined shaft. Anomalous radioactivity was noted in the hanging wall for 225 feet along the fault (surface measurement). Displacement along this fault is more than 2,000 feet since the late Miocene (Yates, 1942). The fault is considered to be part of the ring-fracture system of the McDermitt Caldera. Autunite, meta-autunite, coffinite, torbernite, and gummite are present with pyrite, iron oxides, clays, quartz, and dark purple fluorite. Autunite is reportedly more common near the surface. It has been proposed that uraninite may be present at depth. Uraniumrich zircon occurs as a microgranular, hydrothermal mineral in haloes around clasts and as crustiform layers in radioactive breccia with quartz adularia, arsenopyrite, calcite and others minerals, including galena, sphalerite, barite, and mercury sulfide. The ore is anomalous in Sb, As, Mo, Ag, and most samples have anomalous Ba, Cu, F, Hg, P, Sn, W, and Zr. Two samples contain high Au. Anomalous radioactivity occurs along opalized lenses of Tertiary rhyolitic flows. Uranophane is reported. An undescribed prospect is shown on the Vya sheet, 1: 250,000 scale topographic map. This locality is in an area of volcanic rocks. Organic debris within the Tertiary lake sediments reduced uranium from groundwater or evaporating lake solutions. Bulldozer cuts in the lake sediments have exposed minor uranium concentrations. Small flakes of autunite(?) were noted on fractures in specimens of a Tertiary tuffaceous shale, but the amount present was too low to produce any anomalous radioactivity in hand samples. No anomalous radioactivity was found in the white tuffaceous sedimentary rocks during a 1979 visit (L. Garside, unpubl. data), and no autunite was observed. Drill cuttings on ground were not anomalously radioactive. Anomalous amounts of uranium were found in sedimentary rocks that are part of the caldera moat fill of the McDermitt Caldera. Clay altered(?) rocks, calcareous sediments, and sandstones contain galena, barite, and several uranium- and thorium-bearing minerals (including hydrothermal zircon, and monazite). Pyrite was observed in drill cuttings. Anomalous radioactivity is found along northeast-trending shears that dip steeply east in aphyric rhyolitic ash-flow tuff. A uranium-bearing amorphous zirconium silicate mineral plus framboidal pyrite, barite and limonite were reported. Amorphous zirconium silicate carrying uranium. Peralkaline ash-flow tuff which is mostly aphyric with flow-banded microgranular to granophyric texture, which overlies non-radioactive tuffaceous shale and sandstone to the south. Silicification and argillization are reported, as are pyrite, galena, chaclopyrite, and limonite. Carnotite, uranium silicate (soddyite(?)), and pyrite(?) in bedded tuff in fluvial deposits in the Miocene Virgin Valley Formation. Sample C95-113 was of carnotite and metaankoleite in framboid molds(?) in lignite. Sample C95-114 was of carnotite, opal, and clinoptilolite in air-fall tuff. The samples were taken in fluvial deposits in the Miocene Virgin Valley Formation. Opalized wood with abundant pyrite framboids but no obvious uranium minerals in fluvial deposits in the Miocene Virgin Valley Formation. Radioactive opal with manganese oxide containing uranium in the Miocene Virgin Valley Formation. Radioactive brown opal from fluvial deposits in the Miocene Virgin Valley Formation. Uranium arsenic sulfate from fluvial deposits in the Miocene Virgin Valley Formation. Zeolitized tuff containing no obvious uranium minerals from fluvial deposits in the Miocene Virgin Valley Formation. Samples of radioactive breccia from Miocene Canyon Rhyolite containing an unidentified yellow uranium mineral (C95-110) and carnotite, weeksite, an unidentified uranium silicate, and an unidentified uraniumarsenic phosphate. Sample VV-9 is green fluorescent opal replacing diatomite containing uranium in the Miocene Virgin Valley Formation. Sample C95-115 is opalized air-fall tuff containing less than 40 ppm uranium. A prominent point consists mostly of coarse-grained, light-gray, bedded tuff capped with a resistant ignimbrite. The tuff and ignimbrite strike northeast and dip 15SE. At the west end of the point, the tuff is about 60 feet thick; however 800 feet to the east, it is completely covered by talus (Tuchek and others, 1984). Uranium and thorium mineralization, including a uranium-bearing zirconium silicate, is found in association with iron-oxide staining in volcaniclastic sedimentary rocks which overlie ash-flow tuff. A sequence of gently dipping tuff and ash beds at least 300 feet thick are capped by basalt and terrace gravel. The tuff layers are mostly greenish-gray, friable, and porous; traces of fibrous gypsum, and iron and manganese oxides coat fracture surfaces. The ash beds are generally thinner, lighter colored, and finer grained than tuff. The beds strike northwest and dip 5 to 10NE. Forty-five discontinuous layers of opalite were observed. Some had anomalous amounts of uranium. The layers of opalite occur parallel to the bedding of the ash and tuff and range in thickness from 0.1 to 3.9 feet. The length of the exposed opalite layers is from 8 feet to more than 1200 feet. Many stages of silicification were observed. Less silicified beds resemble shale, whereas thoroughly silicified beds are massive and translucent. The opalite has a distinctive conchoidal fracture and is gray, brown. tan, black, white, and pale green. Irregular and lenselike layers of diatomite, some 7 feet thick, are exposed for more than 2000 feet on the April Fool 1, 2, and 3 claims. An area north of Virgin Valley Ranch, which is about 1 by 0.25 miles and 50 feet deep may contain 15 to 20 million tons of low grade uranium-bearing material, constituting a submarginal resource (Tuchek and others, 1984). Chalcopyrite-bearing quartz veins cut gneissic granodiorite and associated pegmatite dikes. The anomalous radioactivity is reportedly associated with secondary copper minerals which occur as fracture coatings in the quartz veins. Two uranium prospects are shown on the Vya sheet, U.S. 1:250,000 scale topographic map. A prospect in this area called the Yellow Star is shown on an unpublished Atomic Energy Commission map of Nevada uranium occurrences. Schilling (1963) also reports a locality here. No other information is available. Sections 12 and 13 are underlain by Tertiary rhyolite and dacite. Rock mostly quartz-sericite altered granitic rock. Bottom of one shaft is in silty, calcareous, medium gray rock. Uranium mineralization occurs in and near the contact of the Jurassic (145-168 Ma) porphyritic quartz monzonite Austin stock with metamorphosed shales and quartzites of the Cambrian Gold Hill Formation. The intrusive contact is nearly parallel to the bedding in the metasedimentary rocks. Pendants and xenoliths are common. The mineralizing solutions were apparently introduced along silicified fracture zones which occur at the intrusive contact. Uraninite and coffinite are localized by bedding-plane faults, small folds, transverse fractures, and crushed shaly beds along the sides of east-trending, altered, apatite-bearing aplitic dikes or intrusive contact areas. The aplite dikes are. extremely silicified and sericitized. Pyritic and graphitic argillites are the common hosts for the primary orebodies. Pyrite and sparsely distributed blebs of bornite and chalcopyrite are associated with the primary uranium minerals. Silicification of brecciated areas near the intrusive contact was probably accomplished at a late magmatic stage. Aplitic dikes intruded these zones and acted as dams to the mineralizing solutions. Primary orebodies, irregular to tabular in shape, were produced in the favorable metasedimentary zones near the intrusive contact The majority of the ore is secondary, occurring mainly along faults in the quartzites and shales, but also in aplite dikes and the intrusive itself. Autunite, meta-autunite, torbemite, and metatorbernite are present, commonly as individual tabular crystals. Some of these crystals reportedly have centers of uraninite and coffinite. Iron oxides are often present with the secondary ore, bodies of which appear to have been formed by redistribution of uranium by circulating groundwater. Numerous fracture zones in the quartz monzonite are reported to be radioactive in the vicinity of the mine. Two major faults displace the ore but have no evident genetic relationship to the uranium deposition. Most of the mining and development was done at or above the present water table. This locality was visited by the author in 1968 and 1970. Uranophane was noted at the Diamond. Autunite, meta-autunite, rutherfordine, uranoptile, and zippeite are also reported. The bedrock of Sections 6 and 7 is predominantly quartz monzonite of the Jurassic Austin pluton. Geology: A monazite-bearing placer is reported in the Birch Creek district. Slightly anomalous radioactivity is associated with manganese mineralization in lakebeds that are reported to be between ash-flow tuffs of the Bates Mountain Tuff. Manganese ore (47.7% Mn) was reportedly shipped from this mine. Autunite occurs along fracture planes in a thin chert bed. The chert occurs in a sequence of well bedded, horizontal, waterlaid Tertiary tuffs. A minor radioactive anomaly was detected during a helicopter scintillometer survey. Slightly anomalous radioactivity occurs in a graphitic, calcareous argillite of the Cambrian Crane Canyon sequence. Highest radioactivity seems to be associated with graphite-rich areas. The radioactive area is near the intrusive contact with Jurassic granitic rocks. Eleven springs over three acres with temperatures up to 174F. The springs are in Quaternary alluvial fan and lacustrine deposits, and the origin of the radioactivity is not noted. However, Tertiary quartz latite ash-flow Caetano Tuff and rhyolitic ash-flow Fish Creek Mountains Tuff outcrop about 5 miles to the east and southeast. Meta-autunite reported from Bulldog mine. Location is in Quaternary alluvial fan material apparently overlying Tertiary rhyolite intrusive rocks of uncertain age. Anomalous radioactivity is found at a prospect pit in the vicinity of the Cahil Mine. It is associated with a vein with iron- and manganese-oxide minerals; the vein cuts Ordovician Antelope Valley Limestone. Production from the Cahil Mine was mainly gold with some silver. The quartz veins are reported to contain fluorite. Organic-rich spring muck contains 120 ppm U3O8. Autunite(?) was reportedly found near the surface in a bulldozer road during the development of the Cortez gold deposit. The rocks present are mainly Silurian and Devonian limestones. A thin-bedded, water-laid tuff overlain by rhyolite contains areas of anomalous radioactivity. Thin lenses of opal conform with the bedding of the tuff. Both the rhyolite and tuff have reported anomalies, but the highest radioactivity is along minor iron-stained fractures in the nearly horizontal tuffs. No uranium minerals were recognized. High uranium values associated with intermoat sediments of the Fish Lake Caldera. Rock includes arkosic sandstone and lacustrine sediments. Uranium was probably precipitated from uranium-rich water by P2O5 and organic debris. See description for Adit No. 1 Slightly anomalous radioactivity is reportedly associated with iron staining and quartz stringers in Jurassic granitic rocks. Mitchell and Quade (1982) reported that rocks in the pits are not anomalously radioactive. Autunite and anomalous radioactivity occur along a fracture zone in the quartz monzonite. The quartz monzonite is altered to clay minerals, and fractured areas contain limonite veinlets 0.1 to .0.5 inches in width. Silver mineralization is apparently associated with the fracture zone. Radioactivity is associated with an iron-oxide-stained fault-breccia zone in contorted argillites and quartzites of the Ordovician Vinini Formation near the intrusive contact with Jurassic granitic rocks. The fault zone and nearby smaller faults are vertical, and trend north-south. The intrusive contact here has been displaced 15 to 20 feet relatively upward on the east side of the fault. Autunite and metatorbernite(?) have been reported. Anomalous radioactivity occurs in a black, carbonaceous unit of contorted argillites in the Ordovician Valmy(?) Formation. The highest radioactivity is localized in a spot about 1 foot in diameter. Quartz stringers are present locally. The carbonaceous unit was not anomalously radioactive elsewhere in the vicinity. Radioactivity at the Hart No. 3 claim occurs in irregular areas up to 25 feet in diameter in greenish to cream colored, tuffaceous, slightly calcareous siltstones. The beds strike N50W and dip approximately 20SW. The radioactive area is approximately in the middle of the section of Tertiary sediments. Most of the rocks are siltstones. A few sandstone beds were noted in the vicinity. Nearby claims had no radioactive anomalies. The Pinto group claims were not found during a 1970 examination. Well hit 108-foot-thick "blue shale" at 58. "Black sands" sands above and below this shale were radioactive. Sediments encountered are largely fluviatile and sometimes lacustrine. Well hit 108-foot-thick "blue shale" at 89. "Black sands" sands above and below this shale were radioactive. Sediments encountered are largely fluviatile and sometimes lacustrine. Slightly anomalous radioactivity occurs along a 5- to 10-foot-wide zone which roughly parallels a 2-footwide fault zone in silicified limestones and hornfels of the Cambrian Crane Canyon sequence near the intrusive contact with Jurassic granitic rocks. Three areas within a quarter of a mile of each other are anomalously radioactive. The highest radioactivity is localized in small spots, but areas of several thousand square feet are 2 to 4 times background. At Lee Rene No. 5 the high radioactivity is associated with a north-trending fault which cuts yellowish-gray tuffaceous siltstones. Gouge and organic(?) matter in the fault zone apparently concentrated the uranium. At Lee Rene No. 8 radioactivity occurs along certain tuffaceous beds. No uranium minerals were detected. This locality is probably the same as the Rex Jean claims. The Lowboy mine workings are at or near the contact of Jurassic granodiorite and Ordovician Vinini Formation. The intrusive contact nearly parallels bedding in the metasedimentary rocks trending northwest and dipping steeply northeasterly. The metamorphic rocks are hornfels, phyllites, and minor fine-grained quartzites. A 5- to 50-foot-wide alaskite dike appears to have been intruded along or near the granodiorite- Vinini contact. This dike has been hydrothermally altered in all areas seen. The alteration does not appear to have extended appreciably into the granodiorite. The feldspar has been altered to kaolinite in the alaskite, and iron oxides are concentrated along its margins. Iron-staining and minor silicification are present in the Vinini Formation as well, mainly along fractures. The abundant iron oxides may have been produced by acid leaching of pyrite. Most of the ore was produced from overhead stopes which explore certain beds in the Vinini Formation near the granodiorite contact. Mineralization is also present to a lesser extent in the altered alaskite. Secondary yellow and green uranium minerals (including autunite and meta-autunite) occur as thin fracture coatings. Limonite is commonly associated, and hyaline opal occurs rarely. Primary uranium minerals may be present in unoxidized ore at depth, as reported from the Apex mine 7 miles to the northwest. Geology: Quartz monzonite(?). Adit appears to have been driven on hanging wall side of a silicified, ironstained rib of intrusive rock which outcrops prominently as a spine running uphill. Anomalous radioactivity is found in tuffaceous sedimentary rocks which underlie Tertiary ash-flow tuffs and overlie Mesozoic granitic rocks. Some siltstone is opalized. Occurrence is within the ring fracture zone at the southwest margin of the Fish Creek Mountain caldera and is in the welded, rhyolitic, crystal rich Miocene Fish Creek Tuff. Anomalous radioactivity is reportedly associated with iron-stained fractures in a rhyolitic, waterlaid tuff. See description for Adit No. 1 Anomalous radioactivity is found in a garnet-diopside skarn zone which has scheelite, powellite, chalcopyrite, and molybdenite. The skarn is developed at the contact of granite and silty limestone of the Roberts Mountains Formation. Anomalous radioactivity is reported from zeolitized tuff and tuffaceous mudstone which are interbedded with conglomerates and sandstones. A modest radioactive anomaly was detected during a helicopter scintillometer survey of the area, but the anomaly could not be located on the ground. Basinski and Larson (1979) suggested that zeolites or calcium montmorillonite present in the rocks may have acted to concentrate the uranium. Anomalous radioactivity occurs in a 6- to 18-inch-thick bed of silicified tuff or sandstone. Poorly indurated beds above and below are not radioactive. The radioactivity continues in the bed for over 0.33 mi. Uranium anomaly. Visible yellow carnotite in locally silicified limestone close to its contact with Cretaceous(?) granite. Uranium anomaly. Visible yellow carnotite in locally silicified limestone close to its contact with Cretaceous(?) granite. Anomalous radioactivity detected from the air, but no specific areas of radioactivity were found on the ground. The area was mined for diatomite, and the anomaly may be due to removal of alluvium and smearing of weak mineralization over a broad area during diatomite mining. The diatomite occurs in the Panaca Formation. Low-grade gold ore (free-milling) and minor silver and uranium occur in a silicified breccia zone which crops out for 3,000 feet along a fault that strikes N30W and dips 40SW. The breccia is mainly limestone, but contains fragments of quartzite and rhyolite tuff. The breccia is exposed in the 1970s open-pit gold mine. It apparently represents the caldera margin of the Oligocene Indian Hills caldera and tuff dikes are associated with the zone. Silicification and gold mineralization are thought to be related to caldera formation (ca. 29.5 Ma). Five north-trending fissures are present in the mine area. A 1- to 5-foot vein and small bedded replacements in or near the lower limestone in the Pioche shale contain lead, silver, and copper minerals. Uranium minerals were reported in 1930 in this mine. However, Schrader (1931) found no uranium. Psittacinite (a yellow lead-zinc vanadate) has been reported, and may have been mistaken for carnotite. Anomalous radioactivity occurs in a gray, massive tuff of the Panaca Formation. Carnotite occurs as impregnations in carbonaceous material and as coatings on joint surfaces and mud cracks. Pods of pyrite-uraninite ore occur in tabular jasperoid zones along gently dipping faults which contain 1to 4-foot-thick silicified gouge zones. Marcasite has also been identified, and uraninite (pitchblende) is found as spheroids, possibly the result of colloidal deposition with silica. Mineralization appears to have been controlled by an intrusive breccia zone or pipe which was later cut by many minor faults that strike N35-55 W. Yellow secondary uranium minerals (uranophane?) have been reported from near the surface. Pyrite reportedly alters to carphosiderite and pitchblende to gummite. The Ordovician Ely Springs Dolomite is the mineralized unit in the mine. Mineralization is apparently associated with the Oligocene Indian Hills caldera, similar to the Atlanta Mine. Radioactivity is reportedly present in an iron-stained silicified breccia. The wall rock type is not known. No uranium or thorium minerals were recognized. Tschanz and Pampeyan (1970) show the township is largely underlain by Devonian-Mississippian carbonate rock partly overlain in the southern part of the township by Oligocene-Pliocene ignimbrite series of the Tertiary younger volcanic rocks. Uranophane(?) and uraninite(?) were reported from a considerable amount of radioactive float on the property, especially in silicified, brecciated limestone. Slightly anomalous radioactivity occurs along an oxidized copper-gold vein in the Cambrian Prospect Mountain Quartzite. Lead and silver were also produced from the property. The slight radioactivity may be related to a lens of porphyritic diorite which reportedly parallels the vein. Anomalous radioactivity occurs in a gray, massive tuff of the Panaca Formation. Radioactivity on the ground id discontinuous and restricted to butte-like knobs along the bluff and to a single 4- to 5-foot-thick bed. The largest of these in SE, Sec. 9, is less than 0.05 acres in area. Autunite and torbernite occur in 1- to 2-inch siliceous stringers in a white to gray rhyolite flow. Some ironoxide staining is present. Meta-autunite is present with metatorbernite. Dumps and areas near old workings are slightly more radioactive than surrounding unaltered rocks. Calcite, lead and copper carbonates, and cerargyrite are present in siliceous, north- and northeasttrending replacement veins in dolomite. The dolomite outcrop is completely surrounded by ash-flow tuff, and may be a slide block from the wall of the Indian Hills caldera. Autunite was recognized along a fault in diopside-garnet tactite. The autunite occurred as small flakes coating rock surfaces over a short distance along the fault. The intrusive contact with quartz monzonite is nearby. The occurrence is on the 600-foot level in the Moody ore zone, where scheelite occurs in the tactite zone with calcite, fluorite, chlorite, diopside, garnet, quartz, pyrite, pyrrhotite, and minor chalcopyrite and molybdenite. Meta-autunite is also present. Tschanz and Pampeyan (1970) show the township is largely underlain by Tertiary younger volcanic rocks, which is an intermittently erupted Oligocene-Pliocene ignimbrite series consisting of welded vitric and crystal tuffs, pumice or lapilli tuffs, sillars, lahars or tuff breccias, flows, domes, and perlitic rock. A bed of opalized tuff 2 to 10 feet thick is radioactive (0.05 mR/hr) over the entire top of a low hill, some 40 acres. A soft, white, pumaceous tuff underlies the opalized bed. Both units belong to the Pliocene-age Panaca Formation. Carnotite is present in carbonaceous plant remains, as coatings along joint surfaces and mud cracks, and as irregular disseminations, in lenses 2 inches thick and 1 to 2 feet long, in a 1.6-foot zone in a 6foot-thick bed of buff, water-laid tuff of the flat-lying, Pliocene age Panaca Formation. Nearby these beds are unconformable with the Middle Cambrian Highland Peak Limestone. Anomalous radioactivity is present for at least several hundred feet along the outcrop. The 1.6-foot zone contains about 0.05% U3O8 for over 400 feet of exposure. The area of uranium mineralization is believed to represent a paludal facies of the tuff. Anomalous radioactivity occurs along an east-west fissure in the Cambrian Highland Peak limestone. Hematite staining is prominent, and minor amounts of manganese oxides are present. The outcrop of Highland Peak is an inlier, surrounded by Tertiary volcanic rocks. Anomalous radioactivity (probably due to uraniferous opal) is present in a coarse, opalized gray tuff. Minor northeast fracturing is reported. The tuff dips 25E. Slightly anomalous radioactivity is associated with an altered, iron-stained fault zone in granodiorite. The zone is at least 80 feet long, up to 25 feet wide, and trends N65E. Trace uranium in granodiorite. Autunite occurrence. Area is underlain mostly by Triassic mafic volcanic rocks and some Guild Mine Member of the Mickey Pass Tuff. A few stains a yellowish uranium mineral, uranophane(?), were noted at a prospect in rhyolite of the Kate Peak Formation on the Curtiss-Wright property. Fossil bones which occur in Tertiary sandstone and conglomerate are moderately radioactive. Nine quartz veins, 2 inches to 1 foot in width, which strike east, dip steeply, and are surrounded by envelopes of silicified and argillized quartz monzonite, crop out on the claims. Only four of these have yielded samples that contain more than 0.01% uranium. These veins contain thin lenses and aggregates of epidote, chrysocolla, tenorite, chalcocite, chalcopyrite, galena, and argentite. No uranium minerals were recognized. Geology: Uranium, copper, and molybdenum mineralization is present in granite. Chalcopyrite and molybdenite are sparsely disseminated in the granite, and secondary copper and uranium minerals occur along several fractures and sheared areas, especially near aplite dikes. Torbernite occurs as small rosettes in cavities, while autunite is present as encrustations and colloform masses. Phosphuranylite and possibly uranophane also reportedly occurs in the ore. Meta-autunite is also present. Yellow, six-valent uranium minerals occur as thick coatings on northeast-trending fracture surfaces in Tertiary sedimentary rocks. The fracture zones are 8 to 12 feet wide and also contain some iron-oxide minerals. The Tertiary rocks consist of interbedded tuffaceous sandstones and diatomite. Many streamsediment samples from the East Walker River in this part of Lyon County contain over 10 ppm uranium and a few contain over 20 ppm. Autunite(?), meta-autunite, and iron oxides occur along a minor fault near the base of the Tertiary Guild Mine Member of the Mickey Pass Tuff. The fault strikes approximately east-west; carbonized wood is present locally. Anomalous radioactivity is associated with a hot spring which has a water temperature of about 110F. Samples of water analyzed some time after collection contained only 0.002% uranium. The radioactivity of the spring is believed due to radon in the water. Uranium minerals are reported from a highly weathered fault zone in granitic rock. Clay and iron oxides are present along the zone, which trends N65E and dips 80NW. Autunite, meta-autunite, uranophane, and carnotite(?) are reported. Uranophane(?) and zeunerite occur in a shear zone that strikes N80W in granodiorite. Higher radioactivity is present at the intersection of this shear zone with a south-trending fault. Anomalous radioactivity occurs along a north-south trending fault in Cretaceous(?) granitic rocks just below a disconformable contact with the overlying Tertiary ash-flow tuffs. The highest radioactivity is in the gouge zone of the fault, where a very minor amount of autunite(?) was noted. Slightly anomalous radioactivity is present over an area of a few hundred square feet. Meta-autunite also present. Yellow, crystalline uranium minerals occur along a silicified fault(?) zone in Tertiary rhyolite and tuff. This prospect could not be located in 1970. Uranophane is reported from an aplite dike which cuts Cretaceous quartz monzonite. Anomalous radioactivity occurs near the base of Oligocene ash-flow tuff. Two steeply dipping quartz veins trend east-northeast and cut granite. A pod of pyrite, chalcopyrite, galena, limonite and secondary copper minerals has the highest radioactivity. Gold ore from a claim south of the Cambridge mine is reportedly radioactive. The wall rock is granite. Very slightly anomalous radioactivity is present along an iron-stained, westerly trending fracture in a light gray to buff fragmental tuff. The fracture dips 80N. Autunite and meta-autunite is sparsely disseminated in decomposed granitic rock. A copper-bearing quartz vein is reportedly present in the vicinity of the prospect. Radioactive prospects are reported in Oligocene ash-flow tuff from the area south of Ramsey. None of these localities could be found in 1969. Tertiary sedimentary rocks (tuffs, sandstones, shales, etc.) overlie a coarsely crystalline quartz monzonite. Radioactivity is localized in the sedimentary rocks. Durham and Felmlee (1982) reported the radioactivity to be 40 times background at a property they called the Halloween Mine at the geographic coordinates of the River Road Mine. They reported up to 6000 ppm U3O8 in sheared Tertiary siltstone near a fault separating granitic rocks from the sedimentary rocks. Autunite(?), meta-autunite, and torbernite occur locally along a shear zone in quartz monzonite. The zone strikes N30E and dips 50NW. Scattered small nodules of quartz containing galena, chalcocite, and silver minerals are found in gouge along the altered zone. An unidentified yellow radioactive mineral is reported from a highly altered, varicolored, rhyolitic volcanic rock. Zeunerite was identified from a sample reportedly from this claim. Nowak (1979) reported the host rock to be amphibole-rich metasedimentary rock. Uraninite, uranophane, chrysocolla, malachite, and limonite are reported from a milky quartz vein 2 to 4 feet wide. The vein cuts a coarsely crystalline quartz monzonite, and strikes N70W and dips 70S. A water sample from this well contained amounts of radium (2.5 micromicrocuries per liter) which are slightly anomalous for this region. This 540-foot-deep well may penetrate Tertiary sediments and volcanics below the alluvium, and possibly reflects the radioelement content of the volcanic rocks. Radioactivity is associated with thin layers of sulfide minerals in quartz veins which cut a porphyritic quartz monzonite. Four zones of these veins are present on this group of claims. Minerals reported include epidote, barite, galena, chalcopyrite, pitchblende, argentite(?), chrysocolla, chalcocite, torbernite, uranophane, and kasolite. Individual quartz veins range from 1 inch to 1.5 feet thick. Anomalous radioactivity may be in part associated with copper oxides. Carnotite, gypsum, and sulfur(?) are reported as coatings along fractures and joints in diatomaceous beds of Miocene or Pliocene age. The mineralized outcrop was not visible in the prospect pit in 1979. Anomalous radioactivity is associated with silicification, iron staining, and argillization(?) in Tertiary rhyolitic ash-flow tuff. The uranium is apparently concentrated along an iron-stained fracture that cuts a silicified tree limb. Slightly anomalous amounts of uranium were found in select dump samples from Anaconda Copper Co.'s property. The highest radioactivity was associated with heavy coatings of azurite on slightly mineralized porphyry. Uranium apparently became concentrated in the copper leach solutions during ore processing, and there are reports that an attempt was made by Anaconda to recover uranium. Anomalous uranium is found in groundwater in the vicinity of the open-pit mine (Reno Gazette Journal, 3/25/2004). Colored uranium oxide minerals (kasolite?, gummite?, and uranophane?) occur with galena, copper stain, and gold and, silver values in several small quartz veins. The quartz veins occur in granitic rocks, and strike N30 to 40W. Uranophane-beta is present as yellow-orange groups with individual crystals up to 1.5 mm in quartz veins in granitic rock. An iron deposit, mainly magnetite, occurs in a long, narrow roof pendant of Triassic Luning Formation in a granitic intrusive. The roof pendant is nearly a mile long and from a few feet to several hundred feet wide. Small veinlets and lenses of magnetite have replaced limestone. The anomalous radioactivity occurs as patches and lenses in the magnetite. The largest magnetite body occurs on the Black Hawk claim, near the northeast end of the pendant. Zinc and copper minerals are also reported. Radioactivity occurs with iron and copper oxides in a fissure vein in granite. Autunite, meta-autunite, and uranophane reportedly occur in shear zones, probably in granitic rock. One northerly-trending shear zone on the Marietta claims displays anomalous radioactivity over its entire length, and can be traced to the Yellow Sky claims to the north. Metamict thorite is reported from scapolite. This prospect may be similar or the same prospect as the Elna claims. Section 9 is mostly underlain by the Jurassic Dunlap Formation with Jurassic granodiorite along the western edge. Uranium minerals occur as surface coatings and disseminations throughout a well indurated sandstone at or very near the contact with a granitic intrusive. Torbernite(?), saleeite, and novacekite are present with iron staining and clays. Carnotite is present in abundant opalized wood and along altered zones in a rhyolitic tuff. Anomalous radioactivity was noted for about 500 feet along the base of a small hill. This radioactivity may be related to an old lake shoreline. Most of the N of Section 34 is underlain by Triassic carbonate, and the S and central western edge is underlain by Cretaceous quartz monzonite. Carnotite occurs between grains and disseminated along bedding and fractures in Tertiary basaltic, water-laid tuffs and tuffaceous sandstones. The sediments overlie granite, and lie beneath a basalt flow, and are intruded by a small, perlitic rhyolite neck. They are only a few tens of feet thick. The tuffaceous sandstones consist of alternating thin beds of coarse- and fine-grained material, with a 10-foot-thick bentonitic clay unit at the base, above granodiorite. The uranium mineralization occurs along the margin of the perlitic intrusion in the sedimentary rocks. Some radioactivity was also noted in the basalt. The rhyolite neck appears to be younger than the basalts. Conglomerates and boulder beds are interbedded with the basalts higher in the section, but only very minor uranium mineralization was noted in these. Anomalous radioactivity occurs along the brecciated portion of a contact between granitic rocks and a silicified limestone. Opalized portions of this zone seem to be the most radioactive. The limestone is probably part of the Triassic(?) Excelsior Formation. Brecciated portions of a large quartz dike are anomalously radioactive. Iron staining and black (smoky) quartz are reported. The quartz dike cuts a granitic intrusive. Radioactivity is reported along a major southeast-trending fault and occasionally along joint planes in a black porphyritic andesite(?). Autunite and meta-autunite are present, as well as copper sulfate, limonite, hematite, and argentiferous galena. Uranothorite and wernerite (scapolite) reportedly occur in a fault breccia zone. Sec. 2 is mostly underlain by Quaternary alluvium with Pliocene fanglomerate underlying part of the NE. Anomalous radioactivity occurs in fossilized wood in a siltstone lens interbedded with a series of volcanic flows. Radioactive material occurs in local pods and stringers of vein quartz in a fracture system in quartz monzonite. Iron and manganese stains are locally abundant in vein quartz. Radioactivity occurs along a N42W vertical fault zone in Tertiary ash-flow tuff (Mickey Pass Tuff?). The fault zone averages 1 m in width and can be traced for ~150 m. The highest uranium contents are associated with iron oxide minerals and botryoidal copper arsenate. Copper and silver mineralization are the reason for the workings. Radioactivity, generally associated with antimony oxides, occurs along minor faults in a granodiorite. The main antimony ore vein strikes N80E, and dips 65N. Stibnite, galena, antimony oxides, and limonite are reported. Anomalous radioactivity, and yellow, brown, and black uranium and thorium minerals, occur in elongate bodies up to several feet in length. The radioactive minerals have been identified as thorite, huttonite, and uranothorite (Ross, 1961). Very smoky (nearly black) concentrations of radioactive quartz are often present in or near the radioactive bodies. Plagioclase is somewhat altered in the mineralized areas. The radioactive areas occur in an irregular-shaped dike of sodic plagioclase (albitite) in the hanging wall of a fault which separates the dike from the quartz monzonite which it intrudes. Quartz segregations occur in the albitite, but quartz is not present as individual grains in the dike material. The dike rock resembles rocks that have been called Helsinkites in Finland. It consists of sodic plagioclase, with minor epidote and accessory biotite, muscovite, and apatite. Uranium- and thorium-rich areas and radioactive quartz bodies occur as local segregations, both underground and at the surface. The dike is nearly vertical, trends approximately N50W, and has been displaced by faults in several places. It can be found 66 feet from the portal of the adit but occurs in only the floor and a 15-foot-deep winze. The author visited this deposit in 1969. Thorogummite also present. Thin beds of quartzite, slaty rock, hornfels and minor marble intruded by diorite and granite prophyry dikes. Skarn occurs locally and consists of garnet, epidote, calcite, quartz, idocrase, fluorite, molybdenite, pyrite, and a little scheelite. Hand samples largely rhyolite breccia with veins with minor quartz, fine-grained pyrite, sulfides, and some iron-stained gouge. Chalcopyrite present. Silicate zones with garnet, epidote, and gossan along limestone-igneous contact. Butler, Finch, and Twenhofel (1962) report a uranium occurrence at the location given above. It is reportedly of a type which includes veins, breccia zones, stockworks, and related deposits. An iron mine of the same name (Iron Gate mine) is located in Sec. 33, T8N, R35E. It is not known whether this is the same occurrence. Section 35 is mostly by Triassic carbonate, sandstone, and conglomerate with some Cretaceous quartz monzonite in the far SW part of the section. Very slight radioactivity occurs in a diatomaceous bed capped by rhyolite. Radioactivity is associated with magnetite, hematite, and copper minerals which occur sporadically in limestone of the Triassic(?) Excelsior Formation. Jaspery gossan, associated with copper ores, has been prospected for iron. Radioactivity is associated with minor faults in granitic rock, where torbernite occurs as fracture coatings. On the Pink Lady claims, radioactive pegmatites are reported, and possibly contain samarskite(?). A dark rhyolite was very slightly radioactive at one spot. Pyrite was also reported. Radioactivity was detected in veins of calcite, opal(?) and silica (sinter) which cut a dolomite. Mineralization is also present in an underlying black basaltic andesite(?). Copper silicates, calcite, siderite, and uranophane(?) are reported. An altered shear zone up to 100 feet wide strikes N80W in granitic rock. Autunite, meta-autunite, kasolite(?), torbernite(?) and iron oxides are present in subsidiary fractures within this zone. Samarskite and euxinite are present in pegmatite dikes which cut granitic rocks and older hornblende schist and gneiss. Slightly anomalous radioactivity has been reported from the Luning (Sante Fe) district. The radioactivity is probably associated with iron-stained fractures in Tertiary volcanic rocks. The area of radioactivity could not be located in 1970. Anomalous radioactivity occurs sporadically along several 6-inch quartz veins that cut a quartz monzonite. The vein system trends N80W, and continues for 100 feet. Tourmaline, magnetite, pyrite, molybdenite, limonite, and lepidolite are reportedly present. Gold and silver values have also been noted. A silicified rhyolite is slightly radioactive at this locality. Anomalous radioactivity was noted along an iron-stained seam on the 700-foot level. Highly oxidized manganiferous silver veins occur in shales of the Triassic Candelaria Formation throughout the workings. Colored uranium minerals are reported from white Tertiary sedimentary rocks. Occurrence similar to that at Bubbles claims; carnotite is present in abundant opalized wood and along altered zones in a rhyolitic tuff. A radioactive anomaly is reported in altered granitic rocks. Mineralized fractures in a granitic intrusion contain chrysocolla, silver(?), and other copper oxides. These fractures are radioactive. The wall rock is granite. Radioactive occurrences reported along fault and in granite (also possibly in Tertiary sedimentary rocks). The granite may be slightly anomalously radioactive. Metatorbernite(?) occurs in north(?)-trending stringers in granitic rock. Radioactivity is apparently uniformly distributed in certain areas of rhyolite and rhyolitic tuff. No structures were reported. A uranium vanadate, probably carnotite, occurs in opalized plant material (including an opalized log) in a 1- to 3-foot tuffaceous bed. This bed lies at the base of a quartz latite welded tuff(?). Radioactivity is present over a distance of 1,000 feet along this bed. Another nearby tuff bed is also radioactive. Argillized Cretaceous quartz monzonite. Argillized Cretaceous quartz monzonite. Argillized Cretaceous quartz monzonite. Uranium mineralization is in coarse white rhyolitic tuff which nas been mottled with pink hematite stain. The tuff seems to have considerable areal extent and overlies intrusive rocks. It is cut by an andesite dike 30 feet south of the mineralization. 300 feet south of the outcrop a lead-silver showing crops out in underlying instructive rock. This may be related to the uranium. Uranophane(?) and possibly other radioactive minerals occur in small pockets or stringers and veinlets in brecciated quartz veins which also contain lead, copper, gold, and silver. The veins cut a granodiorite intrusion of probable Jurassic age. The radioactive pockets are 1.5 to 2 feet in length, and are found mainly along the footwall of the quartz Radioactive material occurs in thin, limonite-stained quartz veins in granitic rock. The veins are less than 1 inch thick, and several inches to 2 feet long. Anomalous radioactivity is associated with silver, gold, and copper mineralization along a 4- to 12-inchthick vein in granite. Galena, malachite, chalcanthite, chrysocolla, and azurite are reported. Altered shear zones in a granitic intrusion contain iron-stained quartz and radioactive minerals. Kasolite(?) has been reported. Numerous iron-stained seams in a Tertiary andesite breccia locally contain torbernite or metatorbernite. The andesite disconformably overlies Jurassic(?) quartz monzonite. Zeunerite(?) and cuprosklodowskite have also been reported. The uranium occurrence is adjacent to a major east-west fault; the uranium minerals appear to be concentrated with iron-oxide minerals. Some of the nearby quartz monzonite are anomalous in uranium (7-10 ppm); groundwater may have leached uranium from the rocks and deposited it (along with iron-oxide minerals) in fault and fracture zones. Autunite and an unidentified yellow-green uranium mineral are associated with small horses of carbonaceous shale which occur along a highly brecciated and altered zone between coarsely crystalline granite and rhyolitic volcanics. Walker Lake has a high concentration of uranium, 130 ppb. The source of the uranium is uncertain. Anomalous radioactivity, and small amounts of autunite, meta-autunite, and uranophane, are reported from a ferruginous zone near the contact of the Triassic Luning Formation with granitic intrusive rocks. Uranium mineralization is found along fractures. A small amount of marginal grade (about 40% Fe) iron ore is present, plus the usual suite of skarn minerals. Nine-zone pegmatite intruding Cretaceous monzonite and quartz monzonite. Thorite occurs as a rare accessory associated with ilmenite, magnetite, and zircon in the contact between the Amazonite-topaz zone and the perthite zone. An unknown yellow U-Bi-Nb-Ca-Ti silicate mineral forming an alteration product from plumbopyrochlore-plumbobetafite masses and uranium- and thorium-bearing zircons are also reported. The mountain top consists of densely welded rhyolite flows often cut by small veins and veinlets that lead to local areas of brecciation. The matrix of the breccia is filled with a gray to black fine-grained silica and unidentified sulfides that are reported to carry gold-silver values. There are no visible minerals. Alteration within and along the most broken areas was bleached white argillization. Pitchblende(?) and an unidentified yellow uranium mineral occur in an argillized and sericitized shear zone in granodiorite. Pyrite and galena are also reported. The zone strikes N20E, dips 63E, and is 0.5 to 1 foot wide. Autunite occurs along fracture planes and disseminated in quartz monzonite. Radioactivity has also been noted in nearby rhyolite dikes and in shear zones in Tertiary volcanic rocks. Autunite and radioactive fluorescent opal occur along a vertical breccia zone in Tertiary ash-flow tuff (intracaldera tuff of the Moores Creek caldera). The breccia zone trends northeast, and may be along or near the northeast margin of the caldera. Banded, recrystallized, carbonaceous black limestone with 1 to 5% pyrite and pyrrhotite occurring as disseminated grains and thin streaks along the bedding. Strong IP response was present. Anomalous radioactivity is associated with a pegmatite sill that cuts quartzite of the Cambrian Gold Hill Formation. Oxide copper minerals are associated with quartz veins in the vicinity. Autunite occurs along fracture planes in a granitic intrusive. Radioactivity is associated with silicified fault breccias along north-trending faults in a Tertiary rhyolite(?). Uranophane and autunite have been reported. At least five anomalous radioactive areas a few tens to a few hundreds of square feet in area are present in Mio-Pliocene tuffaceous lakebeds of the Siebert Tuff(?). These areas are aligned along a 1-mile northsouth trend which is probably a fault. Anomalies are usually to the east of this fault or within it (in the footwall side). However, at individual prospects, radioactivity is apparently associated with irregular areas in certain tuffaceous sandstones and shales. Iron-oxide staining was noted in some areas. Samples of calcareous tuff reportedly from one locality contained minor amounts of autunite occurring as small, disseminated flakes. No uranium minerals were observed in 1969. Anomalous radioactivity is found in sheared argillite of the Triassic Luning Formation. Abnormal radioactivity occurs at one location, in a 1 square foot area near intersecting fractures in the Cambrian Sterling Quartzite. Copper and iron oxides are present, as well as visible yellow uranium minerals. Anomalous radioactivity occurs with fluorite in a Cambrian limestone. The limestone has been cut by fractures which trend N70W and dip 80SW. Silicification and iron staining are also present. Slightly anomalous radioactivity occurs with purple earthy fluorite in a series of, pipes, irregular bodies, and veins with I pipe-like shoots, in a zone of chaotic structure associated with a large thrust fault. The pipes are localized in crackled zones in dolomite of the Cambrian Nopah Formation. Some tabular bodies are as much as 350 feet long and 250 feet high. Fine crystals of cinnabar in calcite vugs are locally abundant. Ore solutions are believed to have been derived from a nearby chamber of Tertiary rhyolite magma that also erupted a considerable volume of flows, ash flows, and tuffs. Anomalous radioactivity is associated with purple fluorite in a crystal-poor, lithic, iron-stained ash-flow tuff of the Bonita Canyon Formation. The fluorite occurs in stringers, veins, and pods up to 3 inches wide in the hanging wall of a fault that strikes N75W and dips 85S. Fluorite comprises up to 3% of the rock near the fault. Cinnabar is present with the fluorite in some specimens, but is rare in the wall rock. One sample contained 0.035% mercury. A nearby mercury (cinnabar) prospect occurs in the same ash-flow tuff, but no fluorite was noted. The purple coloration in the fluorite is apparently due to radiation damage, and disappears upon heating to 350C. Anomalous radioactivity is reported from an inclined shaft which explores a fault zone separating quartzite from altered quartz monzonite. Iron and manganese oxides, quartz, and gypsum are present. Three radioactive anomalies (U-24, 29, and 30) lie in or just to the west of a near vertical fault that strikes N15E in Mio-Pliocene lacustrine sedimentary rocks (Siebert Tuff?). This fault separates sandstones on the east from shales on the west. On the Atlas group (U-24) the radioactivity is localized in the foot wall of the fault, for a distance of 300 to 400 feet. Radioactivity at the other two anomalies is localized by minor east-west or northwest faults. Most radioactive areas are in fine-grained paper shales and siltstones, but at U-29 a few occur in sandstone units. Autunite and anomalous radioactivity occur in a shallow inclined shaft in quartz monzonite. Iron- and copper-oxide minerals, pyrite, chalcopyrite, and narrow (1-2 inch) quartz veinlets are also reported. Anomalous radioactivity is associated with a 1- to 2-foot-wide quartz which strikes N50E and dips 50SE. Copper oxides and silver mineralization are present. The wall rock is granite. Torbnerite occurs as green, tabular, single crystals and groups in gouge. Metatorbnerite occurs as pale green, translucent crystals with torbnerite. 1973: 5-10,000,000 tons of material grading 0.25 to 0.35% MoS2. Molybdenum occurs as molybdenite and ferrimolybdite. A low grade copper sulfide (chalcocite) zone is also present. The ore minerals are generally disseminated in a massively developed irregular zone of quartz veins in the marginal zone of quartz monzonite stock intruding quartz mica schist, sericitic quartzite, and limestone probably of the Pablo Formation. Mineralization is probably related to the last stages of emplacement of the stock. Radioactivity occurs across a 10-foot zone in a bleached rhyolitic welded tuff (The Bonita Canyon Formation) along a gouge and breccia zone associated with a fault that strikes N55W, and dips 60SW. A slight amount of iron-oxide staining is present. Bleaching and slight radioactivity (1.5 times background) extend along the fault for 100 feet. Minor amounts of torbernite and autunite occur along a fracture zone in steeply dipping, metamorphosed gray shales (Silurian?). Autunite occurs in an altered aplite dike that can be traced for approximately 2,000 feet along a N55E fault zone in Cretaceous granite (73 to 107 million years). The dike is 5 to 6 feet wide and dips vertically or steeply southeast. The aplite is almost completely altered to clay minerals, and contains iron oxides and autunite crystals up to 2 mm long and earthy coatings along fracture surfaces. Anomalous radioactivity is reported from accidental rock fragments contained in a 3-m-thick, poorly welded, felsic ash-flow tuff. This tuff is within a predominantly sedimentary sequence of moat-fill rocks of the Northumberland caldera (McKee, 1974). The source of the mineralized fragments is not known; however, they appear to be strongly silicified volcaniclastic or tuffaceous sedimentary rocks. The rock fragments are dark colored and contain disseminated pyrite; any uranium minerals present have not been identified. Autunite(?) is found as light-yellow to yellow-green coatings and as small, yellow-green platy crystals in cavities and along fractures in the Oligocene tuff of Hoodoo Canyon. The autunite(?) is fluorescent in both short- and long-wavelength ultraviolet light. The cavities which contain the autunite(?) are commonly the sites of former pumice lapilli, which were destroyed during vapor-phase crystallization of the tuff. These cavities are commonly coated with smectite(?) clay. The vitrophyre portion of the tuff of Hoodoo Canyon (McKee, 1974, p. 36-38) is reported to be anomalous in uranium (H.F. Bonham, oral commun., 1980). Anomalous radioactivity, autunite, and torbernite occur along north- and north-east-trending altered fracture zones in a quartz monzonite intrusive. The radioactive minerals are found along fracture planes and disseminated in the altered wallrock. Very minor autunite is found along clay-altered fractures in granite. The radioactivity does not appear to be associated with tungsten mineralization. Abnormal radioactivity occurs at the base of an ash-flow tuff in the Bonita Canyon Formation, a Tertiary, crystal-poor, rhyolitic welded tuff. A 2-foot clay bed(?) was reported. Very slightly anomalous radioactivity is reported from this property. The mine is on a northwesterly bearing vein system in limestone and shale of the Triassic Excelsior(?) Formation near and east of a granodiorite contact. Lead and silver minerals occur in the veins. Lamprophyre dikes of andesitic composition are often associated with the ore zones. Autunite occurs along fracture planes and disseminated in quartz monzonite. Radioactivity has also been noted in nearby rhyolite dikes and in shear zones in Tertiary volcanic rocks. Anomalous radioactivity is associated with gossan in a breccia zone in Paleozoic argillite. The area is underlain by mostly lower Miocene flows, tuffs, and breccias. The gold-rich zone of the Life Preserver Mine is enriched in Th. Autunite and iron oxides are reported from Tertiary ash-flow tuffs and sediments, probably the Shingle Pass Tuff. See description for Foster group. See description for Bobby Jack group. See description for Bobby Jack group. See description for Bobby Jack group. See description for Foster group. See description for Foster group. See description for Bobby Jack group. Four radioactive localities occur in a north-south line about half a mile long. No single structure was noted connecting these prospects. Two occurrences (U-32, U-33) are in light colored shales and siltstones. Sandstone beds present are not radioactive. The other two localities are in buff sandstone, and in one case the radioactivity is associated with calcareously cemented concretions. All four prospects may be in the same stratigraphic interval in lacustrine and fluviatile Mio-Pliocene sedimentary rocks (Siebert Tuff?). See description for Locality U-32 See description for Locality U-32 See description for Bobby Jack group. A very small area of radioactivity was noted in a tuffaceous shale bed. A monazite-bearing placer reported in the district. Autunite occurs as coatings on fracture planes in Jurassic(?) granitic rock. Wolframite and huebnerite are present in quartz veinlets. Anomalous radioactivity occurs along a fault cutting a Tertiary rhyolitic ash-flow tuff. Autunite and an unidentified canary yellow, earthy uranium mineral occur along a silicified fracture zone in a rhyolitic tuff. The structure strikes N80E and dips 60S. The uranium minerals are present in veinlets and along fracture planes. Kleinhampl and Ziony (1984) show a uranium prospect west of Ninemile Peak. They report uranium(?)vanadium-manganese deposits in carbonaceous and siliceous shale-argillite; these are an extension of deposits in the Gibellini district to the north. No evidence is presented (p. 23) that uranium is actually present at the locality. Prospect appears at or near a N-S trending fault with Ordovician Pogonip Group on the east side and Tertiary latitic lavas and tuff on the west (down-thrown) side. An air anomaly is reported from this area. Much of this area is underlain by rhyolitic ash-flow tuffs and some air-fall tuffs and intercalated sedimentary rocks of the Tertiary tuffs of Peavine Canyon which is locally overlain and intruded by later rhyolitic flows, plugs, and dikes. Anomalous radioactivity is found in rhyolitic tuffaceous rocks that are extensively silicified and argillized in the Coral Canyon area. Exploration activity was in the vicinity of the Page Mine. Uranium values and yellow uranium minerals reported (W. Ivosevic, oral commun.). The Page Mine is an antimony prospect. Fractured rhyolitic flows reportedly contain anomalous radioactivity. The locality could not be located in 1969. Torbernite coats fractures in an altered rhyolite porphyry at the bottom of the shaft. The porphyry is a dike in Mesozoic quartz monzonite. Autunite is concentrated along fractures and bedding-plane slips in a black, highly fractured, silicified Ordovician shale. Radioactivity persists to a depth of 17 feet, where it abruptly terminates at a low-angle, southward-dipping fault. The mineralized zone, which varies in thickness from 2 to 5 feet, dips about 45S. and strikes eastward. The Rainbow claims, which are in the area of Air Anomaly No. 3, are reportedly 600 feet from the Valley View shaft. Torbernite and uranophane(?) were also reported. Anomalous radioactivity and iron oxide occur along a fracture in tuff and rhyolite. The fracture trends N10W and dips 60W. Anomalous radioactivity occurs in a crush zone in a dacite(?). Anomalous radioactivity has been reported in ash flow tuffs from this area. Placer gravels in a wash reportedly contain rhyolite fragments and granite wash with a little huebnerite and monazite, together with rare specks of native copper. Autunite and anomalous radioactivity are reported from fracture surfaces in Cretaceous quartz monzonite. The most intense anomaly occurs at the intersection of two vertical fractures which trend N48E and N70W. This prospect apparently lies along the continuation of a N55E fault zone recognized at the Henebergh Tunnel, 0.5 miles to the southwest. Anomalous radioactivity is concentrated at the unconformity between Tertiary ash-flow tuff and Paleozoic shale. The unconformity is marked by a debris flow(?) unit. Anomalous radioactivity was also observed in the ash-flow units. Anomalous radioactivity is associated with heavy iron-oxide coatings along a vein in a fault zone in quartzite near the contact with a quartz monzonite intrusive. Minor amounts of lead, zinc, silver, and gold are reported. Torbernite and autunite are reported from Paleozoic shales. The prospect is a few kilometers north of the margin of the Morey calderon. Anomalous radioactivity is confined to dump material reportedly from a 90-foot shaft. The workings are along the contact between limestone and a granodiorite intrusive. Scattered lead, silver, and gold mineralization occurs along the contact. A trace of scheelite is also reported. Anomalous radioactivity is found in silicified (opalized?) lithic sandstone and volcanic-clast conglomerate below the Tertiary Shingle Pass Tuff. Carnotite(?) is associated with finely disseminated cinnabar in opalized and brecciated Miocene ash-flow tuffs. Anomalous radioactivity is present along a N19E, 65W fault zone in a Tertiary rhyolite tuff and latite. The highest radioactivity is found near the surface, and is associated with limonite coatings on fracture surfaces. Autunite was reported from one locality. Conglomerate and sandstone are reportedly mineralized. Carnotite and anomalous radioactivity are associated with iron-oxide minerals in highly fractured and weathered, interbedded Paleozoic shale, chert, and siltstone. A discontinuous zone 30-100 cm contains up to 0.27 U3O8. V and U are not directly associated. A diorite dike cuts the rocks. The prospect is a few kilometers north of the margins of the Morey and Hot Creek calderas Very slightly anomalous radioactivity is associated with N80 high-angle faults which cut ash-flow tuffs and a gravel between them. Travertine, gypsum, rare uraniferous opal, and iron- and manganese-oxide minerals are present. The minerals were probably deposited by springs. Old workings for tungsten (as huebnerite) followed a shear zone in the granite. Autunite is reportedly present. Anomalous radioactivity occurs along a fracture zone in a rhyolitic ash-flow tuff. The zone trends N25E and dips 80SE. Surface radioactivity is confined to an area 1 foot long and 3 in. wide. Cinnabar occurs as pointy, disseminated crystals with iron oxide in fractures within the silicic ash-flow tuff of the Bonita Canyon Formation. It also occurs in calcite-opal veins with fluorite ands autunite. Union Carbide outlined two areas encompassing almost 500 acres with known sandstone hosted uranium mineralization. The mineralization lies at depths of 900 feet to 1,100 feet. Section 24 is largely underlain by 21-24 million-year-old rhyolitic to rhyodacitic ash-flow tuff of the Toiyabe Quartz Latite. In the southeast section, the Toiyabe Quartz Latite is in contact with an apparently older Tertiary unit of ash-low tuffs, breccias, lavas, and volcanogenic sedimentary rocks of silicic composition. Anomalous radioactivity occurs in granodiorite along a quartz vein which strikes N69W and dips 64SW. The vein is tabular, up to 3 feet wide, and can be traced for 150 feet. Galena, chalcopyrite(?), pyrite, and secondary lead, copper, and iron minerals are present in small amounts. The site is in argillaceous metasediments of hornfels, argillite, slate, and minor quartzite of the TriassicJurassic Auld Lang Syne Group in contact with a Cretaceous granodiorite-quartz monzonite pluton. Yellow and green, nonfluoresecent uranium minerals are found as coatings on fracture surfaces of argillite. Also present as fracture coatings are strongly fluorescent hyaline opal, clays, and an acicular zeolite(?) mineral. 0.5-foot thick iron-oxide stained quartz vein cuts altered granodiorite. Two 1-foot thick aplite dikes enclose 0.3-foot thick veins of iron-oxide stained quartz. The dikes are 5 feet apart and are exposed for 50 feet along strike trending northward and dipping 10 degrees to the west. The dikes cut granodiorite. A 1600-foot thick wide zone of leached and iron-oxide stained quartz veins cutting northeasterly through granodiorite. 6-foot thick iron-oxide stained smoky quartz vein exposed for 7 feet along strike in granodiorite. Anomalous radioactivity is associated with pegmatites and with the contact between altered granitic rock and argillite of the Triassic Auld Lang Syne. Very slight radioactivity is associated with pegmatite and rhyolite dikes in granite. Some specimens of cinnabar ore from this deposit were found to be slightly radioactive. The cinnabar mineralization is associated with a black Triassic shale below a massive limestone. Very slight radioactivity has been reported in a granitic intrusion near the contact with shales. No anomalous radioactivity could be found by Berridge and Wolverson (1982), who reported the granitic rock to contain 2 ppm U3O8. Uranium minerals are reported in metamorphic rocks which occur as roof pendants in a granitic intrusive. The geology is similar to the nearby Four Jacks claims. A small area of anomalous radioactivity was observed in garnet skarn and recrystallized limestone. Autunite and phosphuranylite(?) are found in gray schists and quartzites along and within several pegmatite dikes. The metamorphic rocks occur as scattered roof pendants in a Cretaceous(?) granitic intrusive. Uranium minerals occur along joints and fractures, mainly in the metamorphic rocks. Mineralization usually extends 4 to 6 feet outward from the dikes, with slightly anomalous radioactivity extending somewhat further. Radioactivity was noted for over 50 feet along the strike of one dike. Many of the pegmatite dikes are bleached and partially altered to clay minerals. A yellow, powdery uranium mineral reportedly occurs in association with a highly altered pegmatite dike. Berry and others (1982) reported radioactivity associated with quartz-tourmaline veins and iron-oxide minerals in altered granitic rock. Very slight radioactivity is reported from volcanic flows and tuffs. Anomalous radioactivity is found in Tertiary tuffaceous lacustrine sedimentary rocks in an area previously explored for zeolite minerals. Pegmatite and quartz dikes cut granitic rocks. The anomalous radioactivity is probably associated with the pegmatites. Anomalous radioactivity occurs along a fault zone in rhyolite. Several nearby faults are slightly radioactive, and the radioactivity extends over an area of 2000 by 2000 feet. The radioactivity may be associated with the gold-quartz-tourmaline veins. The highest radioactivity is associated with limonitestained joints in Rochester Rhyolite in a road cut about 150 feet southwest of the main Lincoln Hill Mine adit. Anomalous radioactivity and uranium are found in leucogranite near copper staining. It is associated with limonite staining and jointing. Anomalous radioactivity is associated with limonite-stained joints in quartz monzonite. An aplitepegmatite dike is immediately adjacent. Anomalous radioactivity is associated with limonite stained joints in a pegmatite dike. In the mine area, Triassic limestones and shales have been intruded by a quartz monzonite stock. The limestones have been recrystallized to marble, and the argillaceous beds changed to hornfels and blocky argillites. Scheelite-bearing bodies occur along the intrusive contact. Uraninite and allanite are associated with pyrite and molybdenite in small zones of silicification within the tactite. Uraninite is the main radioactive mineral, but allanite reportedly occurs intergrown in a zonal arrangement with epidote. Majuba Hill is a complex Tertiary rhyolite dome which intrudes Triassic(?) argillites, quartzites, and impure limestones. Three types of rhyolitic intrusive rocks are present, and dike like bodies of chaotic breccias occur throughout the plug. These breccias contain fragments of the surrounding sedimentary rocks as well as the two older types of rhyolite. Both the rhyolites and older rocks have been locally tourmalinized, sericitized, and silicified. Secondary uranium minerals torbernite, metatorbnerite, zeunerite, and metazeunerite occur in a copper- and tin-bearing vein, in the rhyolite porphyry adjacent to the vein, in fault gouge, in tourmalinized intrusion breccia, and in rhyolite and rhyolite porphyry adjacent to the breccia. The vein, which contains the highest grade uranium, is 3 feet wide and contains chalcocite, pyrite, arsenopyrite, and cassiterite. Elsewhere, the metazeunerite occurs with numerous secondary copper minerals, cassiterite, tourmaline, and iron oxides. Fluorite is reported present in some tin-bearing veins. Trites and Thurston (1958) include a composite level and assay map of the mine. Slightly anomalous radioactivity is reported from a very small area of black, carbonaceous upper Paleozoic marine shale. Anomalous radioactivity occurs in ill defined pods mostly along small joints and zones of limonite staining in a Cretaceous leucogranite plutonic mass. The radioactivity in within very light colored, altered leucogranite which is close to copper stained rock. Radioactivity "ore" minerals noted are allanite and zircon. 5-foot thick limonite stained quartz vein and float along a range-front fault paralleling a contact between granodiorite and volcanic rocks. Fault can be traced 6 miles along strike. Autunite and uranophane are found along fractures and bedding planes in shales, phyllites, and schists which occur as roof pendants in a Cretaceous(?) granitic intrusive. Uranophane(?) and uraniferous hyaline opal are associated with intricate and complex, limonite-filled, easterly trending fractures in a quartzite. High radioactivity is present along a 2- to 3-foot zone. The quartzite is a roof pendant in granodiorite, and a pegmatite dike crops out a few feet away. Very minor radioactivity has been reported in sandstone from the Scossa mining district. Radioactivity occurs in and along a 4- to 10-inch-wide zone in a light-gray igneous rock. This rock is part of the Triassic Rochester Rhyolite, which is predominantly ash-flow tuffs. The mineralized structure trends north and dips steeply to the east. This zone is a dark green vein composed of hornblende, diopside, chlorite, biotite, epidote, quartz, dark calcite, pitchblende, and gummite. The intrusive contact with the Rocky Canyon granodiorite stock is about 0.5 mi away. Anomalous radioactivity is associated with oxide copper minerals (including malachite and chrysocolla) in tungsten skarn. The skarn is developed in a roof pendant of Triassic Auld Lang Syne metasedimentary rocks in a Mesozoic granodiorite. Very slight radioactivity is reported in volcanic rocks. A yellow uranium mineral was reported as fracture coatings in a basalt(?) dike which cuts granitic rocks. Berry and others (1982) did not observe uranium minerals but reported radioactivity to be associated with iron and copper staining and a quartz vein in argillized granodiorite. Slightly anomalous radioactivity is associated with aplite, pegmatite, and leucogranite dikes in granodiorite Three 2-foot thick aplite dikes within 400 lateral feet in altered granodiorite. Generally easterly-trending Iron oxide stained contact between Cretaceous granodiorite and Tertiary rhyolite. Slightly anomalous radioactivity is reportedly present along an east-west shear zone which dips 75N. The shear is in limestone near a granite contact. Scheelite, quartz, iron oxides, and molybdenite are reported from skarn mineralization. Some radioactivity is associated with a pegmatite dike. Anomalous radioactivity occurs along nearly vertical fractures which strike N10E. The radioactivity occurs over a wide area in an opalized tuff. Cinnabar and iron oxides were noted. This locality is north of the Washington Hill mercury mine. Tertiary basalt of Catnip Creek. Uranium mineralization occurs in and adjacent to a diabase dike cutting a rhyolitic ash- flow tuff of the Oligocene tuff of Chimney Spring. The diabase dike strikes N30E and has a vertical dip. Secondary yellow uranium minerals (uranophane) occur in the diabase dike and in fractures in the welded tuff adjacent to the dike. The tuff is normally brick red but it has been locally bleached to a greenish-white along fractures. Quartz crystals in the tuff are very black in mineralized areas, probably due to radiation damage. The highest surface radioactivity usually occurs about 3 feet north of the dike. Autunite and meta-autunite are associated with carbonized wood at the base of an Oligocene rhyolitic ash-flow tuff. The tuff was deposited in a paleovalley on granodiorite. Some of the wood is completely encircled or partially replaced by autunite. Autunite is disseminated in and encloses and replaces carbonized wood fragments which occur near the base of an ash-flow tuff overlying granodiorite. A paleosol developed on the granodiorite is also anomalous in uranium. Iron-oxides, autunite(? ), torbernite(? ) and unidentified secondary uranium minerals occur in a northwesterly-trending brecciated shear zone in Oligocene ash-flow tuff. The contact of the tuff with Mesozoic granodiorite is nearby. Torbernite, autunite, and carnotite(?) occur in a fault that strikes N65W, and dips 80NE, and which cuts pre-Jurassic metamorphic rocks, near a contact with a granitic intrusive. Ilmenite(?) may be present. This area is reportedly barely detectable by airborne scintillometer. Several magnetite bodies along veins in metavolcanic rocks are reportedly nearby. Gummite, uranophane, and autunite occur as small disseminated grains in Oligocene rhyolitic ash-flow tuff, which here overlies tuffaceous lacustrine sedimentary rocks. Gummite was reported to be the chief uranium mineral present; however, it is now known to be a mixture of secondary uranium minerals. Mineralization is apparently associated with narrow, iron-stained, silicified veinlets. The principal zone of mineralization is at least 43 m long by 27 m wide, and uranium minerals occur in northeast-trending fractures in a biotite-deficient rhyolite tuff unit. A second mineralized zone strikes northwest and is about 37 m long by 6 m wide. It is found in a biotite-rich rhyolite welded tuff unit, which lies below the biotitepoor unit. Inability of the mine operators to keep the ore grade at or above 0.2% U3O8 is reported to be the reason for cessation of mining on the property. Apparently a moderate tonnage of material averaging somewhat less than 0.2% U3O8 is still present at the Buckhorn mine. An unidentified yellow uranium mineral was reported from along a fault in Oligocene ash-flow tuff, probably the tuff of Dogskin Mountain. Anomalous radioactivity (3- and 14-times background) is limited to clay-altered and iron-stained fractures. Anomalous radioactivity and autunite(?) have been reported from the basal contact of late Miocene fluvial sedimentary rocks and underlying Oligocene tuff of Dogskin Mountain. A light green, bentonitic zone in the sedimentary rocks has the highest radioactivity. Radioactivity is a maximum of 5 times background. Uranium mineralization occurs in and adjacent to an andesite dike which intrudes the Oligocene tuff of Chimney Spring. A fault is present at one side of the dike, and both the dike and fault trend N35 to 70E and dip 65 to 70NW. The uranium minerals occur in pods, stringers, and encrustations along fractures in both the dike rock and the welded tuff. Radioactivity can be detected for up to 500 feet along the structure. According to Brooks (1956) the uranium occurs as autunite, sabugalite, phosphuranylite, clevite(?), and as uraniferous hematite and opal. The higher grade ore occurs in lenticular shoots up to 12 feet long and 4 feet wide within the welded tuff in the footwall of the fault between the dike and the welded tuff. Bleaching and local silicification of the welded tuff are associated with these shoots. Hematite, manganese oxides, and minor opal are present with the ore. Quartz crystals in the welded tuff are very smoky, probably due to radiation damage. Meta-autunite occurs as scaly aggregates in fractures and cavities with sabugalite, phosphuranylite, uraninite, uranospinite, and uranophane. Sample from weathered aplite with white mica and unnamed uranium mineral. Aplite intrudes Cretaceous granodiorite. Autunite and torbernite(?) occur as specks and fine disseminations in charcoal and bentonitic ash at the base of the Oligocene Nine Hill Tuff. The area of uranium mineralization is about 215 by 90 m, and is present along one edge of an erosional remnant of the tuff, which here overlies weathered granodiorite. The mineralized zone is up to 20 feet thick, as exposed in a large cut, and includes volcanic ash with charcoal stringers, and granodiorite boulders up to 4.5 m in diameter. Water well in Cretaceous quartz monzonite Aplite and pegmatite veins and dikes in foliated granitic rocks. Veins and dikes range from several cm up to 1 meter thick. Aplite and pegmatite consists of quartz and feldspar with minor biotite and tourmaline and occasional copper staining. A zone of high radioactivity occurs along the foot wall of a diabase dike which intrudes a tuff of the Oligocene tuff of Chimney Springs. Weeksite tentatively identified as scaly yellow aggregates in fractures and cavities. Uranium mineralization occurs at the base of Oligocene ash-flow tuff for a distance of 75 feet along the strike. Autunite(?) is reported. A zone of intercalated clays, tuffs, decomposed granodiorite, and carbonaceous material lies below the tuff and above the granodiorite. This zone may be up to 10 feet thick, and contains most of the uranium mineralization. Very slightly anomalous radioactivity is concentrated in small faults and in fractures in Oligocene ashflow tuff. The higher radioactivity is associated with heavy coatings of iron and manganese oxides along the fractures. Abnormal radioactivity and a non-fluorescent yellow uranium mineral are present sporadically over an area 300 feet by 1,000 feet. The uranium mineralization is localized along north-trending, steeply dipping breccia zones, fractures, and altered areas in the Oligocene ash-flow tuff, which is highly silicified and iron-stained adjacent to the mineralized fractures. High radioactivity is also associated with fibrous volcanic glass. A uranium- and thorium-bearing pegmatite is reported from this area. The prospect could not be located in 1970. Uranium is present in Holocene dark gray, siliceous sinter formed by precipitation around hot spring pool, and in carbonaceous dark gray to black, soft silty, clay sediments. The prospect may be in the Oligocene South Willow Formation. Slightly anomalous radioactivity has been reported from petrified wood in late Miocene sedimentary rocks (oral commun., H.F. Bonham). Fluorescent uranium minerals occur along a fault zone in tuff beds of the Oligocene ash-flow tuff. Abnormal radioactivity was detected for 100 feet along the fault. Phosphuranylite, calcite, and manganese- and iron-oxide minerals occur with fault gouge along a fault zone in ash-flow tuff. This fault also brings the tuffs into coincidence with pre-Tertiary metamorphic rocks. Autunite(?) and an unidentified yellow uranium mineral (meta-ankoleite?) are found with carbonized fossil wood at the base of a cooling unit in Oligocene ash-flow tuffs. The carbonaceous material is discontinuous, and thickness varies from a few cm about 2 m. Mineralization in the bed can be traced for about a 0.4 km. The beds dip 30-35SW. A yellow, non-fluorescent uranium mineral occurs along N90E, 20N fractures in Oligocene ash-flow tuff. Slightly abnormal radioactivity is present along a north-trending fault zone in the Oligocene ash-flow tuff. Uranium minerals reportedly occur in small pockets, and are reportedly associated with gold. The host rock is a highly fractured, lime-silicate rock containing actinolite and calcite. Uraninite(?), allanite, feldspar, pyrite, limonite, and gold are also reported. Anomalous radioactivity (600 cps, background 60 cps) was observed in a 20 cm by 20 cm spot in calc-silicate rocks during a 1980 visit. Iron oxides and sericite occur in crushed Tertiary Nine Hill Tuff along 1-2 meter wide fault zone that has an attitude of N45E, 85NW-90. Rare quartz veinlets are present. Bulldozer cut here and prospect pits about 22 m east (shown on topographic map) were probably in search of uranium, although no anomalous radioactivity was noted in the Oligocene ash-flow tuff at the site. Malachite and hematite gossan occur with milky quartz vein material in Cretaceous(?) granodiorite. Vein material is not exposed in pits but is seen on small pile of mineralized rock. Anomalous radioactivity is found in a small area (a few feet square) in a felsic dike that cuts quartz monzonite. Uranium mineralization occurs in sedimentary beds in the Oligocene South Willow Formation. The occurrences appear to be spatially related to a rhyolite plug (oral commun., H. F. Bonham). Abnormal radioactivity occurs in a large amount of petrified wood in late Miocene sedimentary rocks (oral commun., H.F. Bonham). A short adit and nearby prospect pit explore Oligocene ash-flow tuff (tuff of Axehandle Canyon?) where it lies on mafic Mesozoic metavolcanic rocks. No obvious mineralization was observed. Locality is within a 1,600-foot diameter argillic alteration halo. The halo also contains surficial sericite alteration and a couple of outcrops of chalcedony but lacks a well-developed zone of kaolinization. Several uranium minerals, including autunite, torbernite(?), and pitchblende(?), have been reported from this locality (AEC Report 3768). The uranium mineralization is found in a fault breccia in Oligocene tuff of Dogskin Mountain, which also contains iron oxides. The fault trends N80W and dips 55S. No uranium minerals were observed in 1980. The tuff is silicified, argillized, and locally contains disseminated pyrite. Because this area is within the alteration halo of the Pyramid Mining District, it is probable that the pyrite and hydrothermal alteration are related to that period of mineralization. Uranium mineralization occurs in and adjacent to a N10-20E fault zone in welded Oligocene rhyolite ash-flow tuff. Anomalous radioactivity extends along the fault for about 200 feet in a zone up to 10 feet wide. U.S. Atomic Energy Commission geologists (A.E.C. PRR-3775) who examined the property in 1955 reported uraninite, autunite, uranospinite, uraniferous opal, and barite. However, Bonham (1969) recognized only autunite and a yellow secondary uranium mineral (probably uranophane). Brooks (1956) also reports the presence of radioactive manganese oxide. Autunite and an unidentified yellow, crystalline uranium mineral occur in welded and non-welded tuffs of Oligocene rhyolitic ash-flow tuff. Anomalous radioactivity and yellow uranium minerals (autunite?, weeksite, carnotite, uranophane?, and haiweeite) are found at one locality in a small prospect pit along a 15 cm thick volcanic ash bed. The radioactive bed lies directly below the lowest massive, red, Oligocene ash-flow tuff, and above about 6 m of slightly bentonitic ash. The ash-flow tuff lies with angular unconformity over steeply dipping black Triassic(?) limestone of the Nightingale sequence. Radioactivity is not continuous along the bed in outcrop. Detailed geology is uncertain, but claims are in Oligocene ash-flow tuffs, variably welded, ranging from rhyolite to quartz latite in composition. At one locality, slightly anomalous radioactivity (350 cps, background 100 cps) was noted along a N25W, 70-80SW fault cutting rhyolitic ash-flow tuff. The radioactivity is found at a roll or inflection in the fault surface, which occurs at the intersection with a cross fault. Anomalous radioactivity has been reported from pegmatite-quartz veins in Cretaceous granodiorite. Numerous pits and shallow workings explore bleached and slightly iron-stained fault zones in a quartzlatite welded tuff. The tuff is purple with conspicuous white pumice lapilli up to several cm in diameter. The area contains aplite and pegmatite dikes trending about N20E that cut Cretaceous(?), medium to coarse grained, light gray to nearly white, biotite quartz monzonite of Granite Peak. These dikes are commonly 30 cm to 1 m thick, but may be up to 3 m thick and may be either pure aplite or aplite and pegmatite mixed in varying proportions. A small cut reportedly contained a pegmatite dike varying from 0.3-2.4 m thick with a footwall attitude of N15W, 70E, and composition of 60-70% quartz with the remainder being pink perthitic feldspar and minor muscovite and other minerals. The 1945-1947 cut exposed a 1-m-thick pegmatite body trending N50-60W, 60-70NW, with a composition of about 25% quartz, almost 40% blocky pink perthite, about 35% clevelandite in up to 10 cm long platy crystals. Minor minerals include less than 2.5 cm blades of biotite, accessory minerals, and rare allanite. No beryl was present. Carnotite was reported in a specimen collected from this pit. Anomalous radioactivity is reported in partially silicified sand and diatomite beds. This property could not be located in 1970. Alluvium overlies gray rhyolite containing feldspar phenocrysts. Ten samples from alluvium and rhyolite contained trace gold and silver and less than 0.005% U3O8. Lacustrine sediments of Pleistocene Lake Lahontan are radioactive in an area of a few tens of square feet. The rocks are cobble conglomerates and cross-bedded sandstones which are cemented by and interbedded with calcareous tufa. The clastic debris is mainly from older volcanic rocks. No uranium minerals were noted, and radioactivity does not appear to be restricted to particular beds or other structural features. Autunite reportedly occurs in coatings on pebbles and in small pockets in sandstone. Bonham and Papke show the closest bedrock to be Tertiary Pyramid Sequence sedimentary and volcanic rocks. Autunite, carnotite(?), and torbernite are present in a fault zone in metamorphic rocks. No samples were analyzed, but a high thorium content was reported. Bonham and Papke show the closest bedrock to be Tertiary Pyramid Sequence sedimentary and volcanic rocks. Details of the geology are unknown, but on the map of Bonham and Papke (1969), the prospect is located near or on a fault in Oligocene ash-flow tuffs. Anomalous radioactivity is reported from tuffaceous sediments in the Tertiary Chloropagus Formation. Anomalous radioactivity is present in Oligocene ash-flow tuffs. Occurrence is near contact of Miocene-Pliocene basalt and sediments. Samples contained trace gold and silver and less than 0.005% U3O8. Select calcite and quartz vein matter from dumps. Sheared Oligocene ash-flow tuffs contain local concentrations of organic material with assays up to 48 ppm U3O8. Anomalous radioactivity is associated with silicified tree stumps in a rhyolitic tuff. Anomalous radioactivity is associated with silicified and carbonized logs and other plant material at the base of the Oligocene tuff of Axehandle Canyon. The tuff is densely welded here, and overlies a roof pendant of biotite-rich gneissic rock in a granodiorite intrusion which crops out nearby. The metamorphic rocks have been cut by aplitic dikes and apophyses of granodiorite. The rhyolite ash-flow tuff was apparently deposited in a paleovalley cut in granodiorite. The logs and other material are found below the perlitic vitrophyre base of the tuff in an ash-rich bentonitic unit, which apparently occurs near the bottom of a paleovalley. Several small faults and fractures are present, but the radioactivity does not seem to be localized along them. Sabugalite and autunite occur in the wood, and disseminated in the weathered metamorphic rocks. The uranium minerals are more abundant in the silicified portions of the logs. Anomalous radioactivity, up to 750 cps (counts per second), is associated with fault breccia along a N50W, 80SW fault which cuts a silicic ash-flow tuff of the tuffs of Whiskey Spring. Background radioactivity in this tuff is 90 cps, and is about 50 cps Interbedded peat, clay, and sand in a bog. The bedrock is Cretaceous monzo granite of Spooner Summit. Interbedded peat, clay, and sand in a bog. The bedrock is Cretaceous hornblende-biotite granodiorite. Uranium mineralization (autunite) is found within and adjacent in the footwall to an andesite dike which intrudes the Oligocene tuff of Painted Hills (Faulds and others, 2003; Garside and others, 2003). The footwall contact zone of the dike has been faulted, and both the dike and fault strike N35 to 70E and dip 65 to 75NW. Mineralization occurs in lenticular shoots up to 4 feet thick and 12 feet in diameter. Uranium assays up to 15% have been obtained from the mineralized zone, however mineralization of economic interest is generally pod-like and discontinuous. Minerals include autunite, clevite(?), phosphuranylite, sabugalite, and uraniferous hematite and opal. A large granitic aplite-pegmatite dike (150 feet by 500 feet) that cuts a Jurassic(?) quartz diorite intrusion contains several small segregations of allanite pegmatite. The dike strikes east-west and is nearly vertical. Eight allanite pegmatite bodies are reported in the dike. The allanite occurs as euhedral to subhedral crystals as much as 6 cm. long and 1 cm. wide in an aplitic matrix of quartz, albite, and microcline. Allanite content varies from 5 to 30%. The large aplite-pegmatite dike is probably related to a pluton of quartz monzonite which intrudes the quartz diorite about 1 mile east of the prospect. Tschefjkinite (a rare earth titanite-silicate) has been reported from the Deer Lodge claims. Devitrified Oligocene Nine Hill Tuff. Detailed prospect geology uncertain, but Sec. 2 includes silicic Oligocene ash-flow tuffs that have uranium mineralization elsewhere. Spring in Cretaceous quartz monzogabbro Radioactivity is found in Oligocene rhyolitic ash-flow tuff. The most anomalous radioactivity was noted in a 6-m adit in white, unwelded basal Nine Hill Tuff just below the basal densely welded zone. Radioactivity in the short adit is about 1000 cps; background is about 100 cps. The highest radioactivity was observed on carbonized wood in the tuff. Fragments of carbonized and silicified wood and plant material 1-100 cm in length occur in the tuff parallel to compaction foliation in the overlying welded zone. Uranophane(?) occurs as rare coatings on fractures in the tuff. Radioactivity occurs along a clay-altered and hematized fault zone in Oligocene ash-flow tuffs. The fault is nearly horizontal. The most radioactive area (30 x background) is a 3-cm zone of clay gouge. Autunite and phosphuranylite occur in or adjacent to the ash-flow tuffs. Yellow uranium minerals (uranophane?) occur along a tectonic(?) breccia zone which occurs in the basal portion of the Nine Hill Tuff. The breccia zone appears to have an attitude of N70E, 80SE, and is 5-6 m wide. The most radioactive area is in the footwall of the breccia zone. The background radioactivity is 200 cps; the highest recorded was 10,000 cps. Oxidized pyrite(?) was noted in some samples. The Nine Hill Tuff is a vitric welded tuff with dark, elongate compacted pumice. Fluorine is reported to be high in samples from the prospect (Steve Hendricks, oral commun., 8 May 80). Autunite, uranophane(?), and gummite have been reported. The adit was driven on a gouge and breccia zone which trends N55E and is vertical. A yellow-green, fluorescent, uranium mineral (meta-autunite?) and iron-oxides are associated with charcoal and fossil wood in tuffaceous and conglomeratic sandstone at the base of the Nine Hill Tuff. Northwest-striking faults may also control mineralization. Castor and Henry (2000) reported chalcedonic and granular quartz veins that cut Nine Hill Tuff about 50 m NW of the canyon. Spring in Cretaceous quartz monzogabbro One sample of lignite from the Tertiary Truckee Formation was very slightly radioactive. Nearby lignitic beds were not radioactive. Thin clay beds in Pliocene to Pleistocene(?) sedimentary rocks (Faulds and others, 2003) contain 15 to 32 ppm U3O8. Uranium is in disequilibrium in favor of equivalent uranium (Cupp and others. 1977a, 1977, p. 28). The prospect is at the mouth of Mine Canyon, which drains an area having several uranium prospects. The sedimentary rocks are cut by a strand of the Warm Springs Valley fault system. Anomalous radioactivity is associated with organic material and petrified wood in light gray, Tertiary airfall tuff and tuffaceous sediments. Anomalous Mo and Y are reported. Anomalous radioactivity occurs in a sequence of upper Tertiary sandstones and siltstones. Sporadic humic-rich areas in a cream-colored claystone are somewhat radioactive. The prospect is in beds that are only a few feet above the nonconformable contact with granitic rocks. This spring is reported to be slightly radioactive. A north-south brecciated zone, 125 feet wide and 5 feet thick in quartzite is anomalously radioactive. An intrusive contact with granitic rocks is associated with the radioactivity. Also, there is a latite porphyry intrusion nearby. One main spring and several smaller springs with a maximum reported temperature of about 193F in 20 to 40-foot high travertine mound covering 12 acres in Quaternary alluvium. The source of the radioactivity is not noted but Tertiary(?) quartz monzonite outcrops about 3 miles to the southwest. Some travertine from pools is reported to be anomalously radioactive (about 200 counts/sec above background; (G. Dixon, oral commun., 1980). A 5-square-mile area of quartz monzonite contains accessory minerals which include allanite, monazite, sphene, apatite, zircon, garnet, and epidote. Allanite and monazite are present in amounts from 0.04 to 0.12 weight%, and vary with CaO content of the quartz monzonite. The intrusion has been dated as 145 20 Ma at this locality. The ThO2 content of the allanite ranges from 1 to 2%, and from 6 to 14% in the monazite. Rare-earth oxides are present in the allanite and monazite in amounts from 20 to 75 weight%. Scattered autunite crystals occur in vugs and along fractures in a Tertiary latite(?). Meta-autunite also present. Anomalous radioactivity occurs along fractures in metamorphosed Paleozoic limestones. Top meter of pit appears to be a cap of jasperoidal material. Below the silty mudstone(?) is cut with stringers and pods of purple microcrystalline fluorite. Surface is highly kaolinized. The locality is reportedly a silver prospect, and is located about 1 mile southwest of the Hunter mine, a lead-copper-silver mine.
