  9. What do these have in common? • Big Bang • Fusion in stars • Supernovas

  10. Which list makes up 90+% WHOLE earth? Iron 35-40% Oxygen 25-30 % Silicon 13-15% Magnesium 10% Oxygen 47% Silicon 28 % Aluminum 8% Iron 5% How do you know?

  11. 4 Characteristics of ALL Minerals 1. 2. 3. 4.

  12. Mineral Families You can tell which family a mineral belongs to by looking at its formula. There are 9 families to learn:

  13. Native elements • Minerals that are from 1 element • Gold: Au • Copper: Cu • Silver: Ag • Carbon: C • Sulfur: S

  14. 2. Halides • Halogen Group. • Halite: NaCl – salt, rock salt • Fluorite: CaF2

  15. 3. Oxides • Minerals with oxygen • Ice H20 • Corundum Al2O3 • Hematite (Fe2O3) • Magnetite (Fe3O4),

  16. 4. Sulfides • Minerals with sulfur; rotten egg smell • Galena (PbS for lead used in pipes and bullets), • Chalcopyrite (CuFeS2, copper & iron ore AKA fool’s gold) • Pyrrhotite (Fe4S) • Pyrite – Iron ore – cars, steel buildings (FeS2) • Sphalorite - ZnS • Bornite – Cu5FeS4 copper ore – pipes, wire

  17. 5. Carbonates • Minerals with Carbonate (C03) • Calcite – (CaCO3), – very abundant • Dolomite – (CaMg(CO3)2) lime • Azurite - Cu3(CO3)2 • Malachite – Cu2(CO3)( copper ore and ornamental

  18. 6. Sulfates • Minerals with Sulfate S04 • gypsum (CaSO4 · 2H2O), – plaster of Paris, wall board • barite (BaSO4)

  19. 7. Hydroxides • Minerals with a metal plus hydroxide (OH-) • limonite (iron hydroxide) Fe40i(OH)2 • bauxite (aluminum hydroxide) Al(OH)3

  20. 8. Phosphates • Minerals with a metal plus phosphate (PO4) • Apatite - Ca5(PO4)3F

  21. 9. Silicates • Minerals with silicate tetrahedron SiO4 • 90% of rock forming minerals • Not ores • Examples: Quartz (most common mineral) Opal, talc, mica, hornblende, topaz, feldspar,olivine Look for Si O in formulas KAlSi3O8, Al2SiO4, SiO2*H2O

  22. Different Arrangements of SiO4
