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...
