Minerals containing borate anion groups (e.g., Borax).
Minerals containing the carbonate ion (CO3)2- (e.g., Calcite, Malachite).
Compounds containing a halogen element as the main anion (e.g., Halite, Fluorite).
Minerals composed of a single element in its native state (e.g., Diamond, Gold).
Rare minerals formed through biological or organic processes (e.g., Whewellite).
Compounds of oxygen with one or more metals (e.g., Hematite, Corundum).
Minerals containing the phosphate ion (PO4)3- (e.g., Apatite, Turquoise).
The largest class, containing silicate tetrahedra (SiO4)4- (e.g., Quartz, Feldspar).
Minerals containing the sulfate ion (SO4)2- (e.g., Gypsum, Baryte).
Compounds of sulfur with metals or semi-metals (e.g., Pyrite, Galena).
