Who cares about minerals: besides mineralogists . , geologists, environmental scientists, chemists, civil engineers, biologists, mining engineers, electrical engineers, chemical engineers, civil engineers, archeologists, nanoscientists, jewelers, economists and entrepreneurs. Authentic aztec or mixtec mask with turquoise mosaic inlays, ad 1400-1521. In fact, mineralogy is the language of geology: minerals form at particular conditions, (p, t, ph, eh, rates, [h2o], composition, minerals help us to understand how a rock formed, and also what changes it has experienced. Hydroxyl group (oh) in formula requires a lot of water (h2o)during formation! Know your minerals: name, chemical formula, crystal system, cubic, hexagonal, tetragonal, orthorhombic, monoclinic, triclinic, physical properties, cleavage, hardness, relative density, color, streak luster, other, chemical properties, (e. g. , solid solutions, common defects, occurrence, mineral associations, use. Classified by major anion: cation -positive charge, mg2+, fe3+, k, anion -negative charge, o-, cl-, sio4-4. Classified by major anion, by james dana"s system: native elements, sulfides, halides, oxides, hydroxides, carbonates, sulphates, phosphates, tungstates, molybdates, silicates.
