Mineral families

Mineral Families

You can tell which family a mineral belongs to by looking at its formula.

There are 9 families to learn:


Native elements

Native elements

  • Minerals that are from 1 element

    • Gold: Au

    • Copper: Cu

    • Silver: Ag

    • Carbon: C

    • Sulfur: S


2 halides

2. Halides

  • Halogen Group.

  • Halite: NaCl – salt, rock salt

  • Fluorite: CaF2


3 oxides

3. Oxides

  • Minerals with oxygen

    • Ice H20

    • Corundum Al2O3

    • Hematite (Fe2O3)

    • Magnetite (Fe3O4),


4 sulfides

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


5 carbonates

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


6 sulfates

6. Sulfates

  • Minerals with Sulfate S04

    • gypsum (CaSO4 · 2H2O), – plaster of Paris, wall board

    • barite (BaSO4)


7 hydroxides

7. Hydroxides

  • Minerals with a metal plus hydroxide (OH-)

    • limonite (iron hydroxide) Fe40i(OH)2

    • bauxite (aluminum hydroxide) Al(OH)3


8 phosphates

8. Phosphates

  • Minerals with a metal plus phosphate (PO4)

    • Apatite - Ca5(PO4)3F


9 silicates

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
