Paleontology – study of fossils Mineralogy – study of minerals Hydrogen – element with one Proton Olivine is the first mineral to appear in the Bowen reaction series 1 mile = 1.609344 kilometers 1 pound = 0.45359237 kilograms 1 ton = 907.18474 kilograms Celsius= (5/9)*(Farenheit-32) 3 axes of 4 fold symmetry in a cube Olivine and pyroxene are a reaction pair Silica is a positivity charged ion Quartz is the last mineral to form in the Bowen Reaction Series Bragg’s law is d-spacing Angstrom is 10 to the -8 cm Olivine to Biotite is a discontinuous reaction series The First Six Elements – H, He, Li, Be, B, C Radius of the Earth – 6370 km Geothermal gradient of 20 degrees C per kilometer, temp at center = 127400 (multiply temp by 6370) Atom is the smallest possible particle of an element that retains the properties of a true element 3 most abundant elements in the earth’s crust – O, Si, Al Dissimilarities in abundances of elements between the sun and the earths crust suggest that the

Unformatted text preview: earth is chemically zoned. Speed of light (km/sec) = 299792.458 km/s 1 kb = 3 km, so center of earth for kb is radius / 3 The average density of the earth is 5.1 g/cc^3 Rhyolite and Granite are associated with high silica contents Volume of a sphere is 4/3 pi r^3 so volume of earth is 1.08 e12 Rocks aggregate of minerals Igneous, Sedimentary, Metamorphic If all igneous rocks were analyzed the two most would be basalt and Rhyolite (with relation to SiO2) Bowen Reaction Series o Starts high temperature at the top, low temperature at the bottom o Left side of the Y is discontinuous, right side is continuous. o Olivine -> Pyroxine -> Amphibole -> Biotite on the left side o Calcium Rich -> Plagioclase -> Sodium Rich on the right side o Orthoclase -> Muscovite -> Quartz on the stem o Starts around 1400 degrees and goes toward 800 near the end o Nd = 3a Sin (Theta) o...
