  • 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
    fools 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, SiO2H2O

22
