Introduction to Mineralogy Dr. Tark Hamilton Lecture 1 Camosun College GEOS 250 Lectures: 9:30-10:20 M T Th F300 Lab: 9:30-12:20 W F300 Klein & Dutrow, 2008 fig_01_01 Mineralogy Other Disciplines • Structure: Recrystallization = new fabrics • Tectonics: Dehydration reactions release fluids & trigger quakes • Geochronology: Datable minerals hold both parent and daughter isotopes • Petrology: Partition or order/disorder of elements serves as geothermometer & geobarometer recording P,T conditions Mineralogy Other Disciplines • Geochemistry: Composition of minerals records reservoirs, fluids and processes • Meteoritics: Composition, age & conditions of early solar system & early thermal separation of atmophile, chalcophile & siderophile elements • Planetary Studies: Lunar rocks Apollo 11 & 16, Shergottites & Mars Rover spectra Mineralogy Other Disciplines • Paleontology: Fossilization replacing organic matter by minerals; silica, pyrite, calcite, apatite • Geomicrobiology: Archae bacteria & nannobacteria & extremophiles depositing minerals. Sulphate reduction to Sulphide • Environmental: Heavy metals cycling, acid rock drainage, filtration, fixation, soil chem Mineralogy Other Disciplines • Economic Geology: Ore formation & Separation, Associations: Calcite & Pyrite nullify ARD, FeAsS Arsenopyrite reduces Au ore value as does AuTe2 Calaverite or Pd3HgTe3 Temagamite • Geophysics: Gravity = density, Susceptibility & induction = magnetism, Seismic velocity = compressibility, bulk & shear modulus, density, Electromagnetism = eddy currents, polarizability, Radioactivity = U, Th, K content Mineralogy Other Disciplines • Mineral Physics: Study of planetary interiors, seismic discontinuities, spherical harmonics, phase transitions, monolayers, nannocrystals, materials science • Economics: Precious & rare metals, Au, PGE’s, Base Metals (Cu,Zn,Pb), Gems, Industrial minerals, Wallboard, Ceramics, Glass, Portland cement, Zeolite filters, Clays for mud wrestling
