The sulfate minerals are a class of minerals which include the sulfate ion (SO42−) within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits. The chromate and manganate minerals have a similar structure and are often included with the sulfates in mineral classification systems.
Sulfate minerals include:
Anhydrous sulfates
Barite BaSO4
Celestite SrSO4
Anglesite PbSO4
Anhydrite CaSO4
Hanksite Na22K(SO4)9(CO3)2Cl
Hydroxide and hydrous sulfates
Gypsum CaSO4·2H2O
Chalcanthite CuSO4·5H2O
Kieserite MgSO4·H2O
Starkeyite MgSO4·4H2O
Hexahydrite MgSO4·6H2O
Epsomite MgSO4·7H2O
Meridianiite MgSO4·11H2O
Melanterite FeSO4·7H2O
Antlerite Cu3SO4(OH)4
Brochantite Cu4SO4(OH)6
Alunite KAl3(SO4)2(OH)6
Jarosite KFe3(SO4)2(OH)6
