Sulfate minerals

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.[1]

Sulfate minerals include:

Nickel–Strunz Classification -07- Sulfates

Hanksite, one of the rare minerals that is a sulfate and carbonate

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses it to modify the Classification of Nickel–Strunz (, 10 ed, pending publication).

Class: sulfates, selenates, tellurates

Class: chromates

Class: molybdates, wolframates and niobates
