  • 2.3 Mineral GroupsPhysical Geology

    2.3 Mineral Groups Most minerals are made up of a cation a positively charged ion or several cations and an anion a negatively charged ion e.g., S 2 or an anion complex e.g., SO 4 2. For example, in the mineral hematite Fe 2 O 3, the cation is Fe 3 + iron and the anion is O 2 oxygen. We group minerals into classes on the basis of their predominant anion or anion group.
