Formula for galena
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 42–). 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 ...Sphalerite has been found as a pseudomorph, taking the crystal structure of galena, tetrahedrite, barite and calcite. Sphalerite can have Spinel Law twins, where the twin axis is [111]. The chemical formula of sphalerite is (Zn,Fe)S; the iron content generally increases with increasing formation temperature and can reach up to 40%.
