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.〔Klein, Cornelis and Cornelius S.
