2.3 Mineral Groups Physical 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.
