Most minerals are made up of a cation (a positively charged ion) or several cations, plus an anion (a negatively charged ion (e.g., S 2− )) or an anion complex (e.g., SO 42−). For example, in the mineral hematite (Fe 2 O 3 ), the cation is Fe 3+ (iron) and the anion is O 2− (oxygen). The two Fe 3+ ions have an overall ... Sphalerite. Crystal System: Cubic. Formula: ZnS.
