# Sulfate mineral

The sulfate minerals are a class of minerals that include the sulfate ion (SO$^{2−}$ $_4$) 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 BaSO$_4$
** Celestite SrSO$_4$
** Anglesite PbSO$_4$
** Anhydrite CaSO$_4$
** Hanksite Na$_{22}$K(SO$_4$)$_9$(CO$_3$)$_2$Cl
* Hydroxide and hydrous sulfates
** Gypsum CaSO$_4$·2H$_2$O
** Chalcanthite CuSO$_4$·5H$_2$O
** Kieserite MgSO$_4$·H$_2$O
** Starkeyite MgSO$_4$·4H$_2$O
** Hexahydrite MgSO$_4$·6H$_2$O
** Epsomite MgSO$_4$·7H$_2$O
** Meridianiite MgSO$_4$·11H$_2$O
** Melanterite FeSO$_4$·7H$_2$O
** Antlerite Cu$_3$SO$_4$(OH)$_4$
** Brochantite Cu$_4$SO$_4$(OH)$_6$
** Alunite KAl$_3$(SO$_4$)$_2$(OH)$_6$
** Jarosite KFe$_3$(SO$_4$)$_2$(OH)$_6$

## Nickel–Strunz classification -07- sulfates
