Unit Objectives:

  • Apply your understanding of atoms to explain bonding within minerals
  • Describe mineral lattices and explain how they influence mineral properties
  • Categorize minerals into groups based on their compositions
  • Group Examples (Note: Minerals in BOLD = memorise the formula)
    Oxides Hematite (iron oxide Fe2O3),  magnetite (Fe3O4), water ice (H2O)
    Sulphides Galena (lead sulphide PbS), pyrite (iron sulphide FeS2), chalcopyrite (copper-iron sulphide CuFeS2), sphalerite (ZnS), and molybdenite (MoS2), bornite (Cu5FeS4)
    Sulphates Gypsum (calcium sulphate CaSO4·H2O)  (Note that sulphates are different from sulphides. Sulphates have the SO4–2 ion while sulphides have the S–2 ion)
    Halides Fluorite (calcium flouride CaF2), halite (sodium chloride NaCl) (Halide minerals have halogen elements as their anion — the minerals in the second last column on the right side of the periodic table, including F, Cl, Br, etc. — see Appendix 1.)
    Carbonates Calcite (calcium carbonate CaCO3), the copper minerals malachite and azurite are also carbonates (these minerals will all fizz in acid)
    Phosphates Apatite (Ca5(PO4)3(OH)) (this is what your teeth are made of)
    Silicates Quartz (SiO2), feldspar (sodium-aluminum silicate NaAlSi3O8), olivine (iron or magnesium silicate (Mg,Fe)2SiO4)   (Note that all igneous rocks are composed of silicate minerals.)
    Native minerals Gold (Au), diamond (C), graphite (C), sulphur (S), copper (Cu)
  • Explain some of the mechanisms of mineral formation
  • Describe some of the important properties for identifying minerals:
 simple crystal shape/habit
 streak/ fracture
 magnetism
 specific gravity (relative density)
 lustre
 hardness
 special properties, such as reaction to dilute HCl
 cleavage
 colour
