WebPyrite. Pyrite is the most abundant and widespread sulfide mineral (FeS 2 ). It rarely makes up the bulk of the rock, but it frequently occurs in rocks. It is a common mineral in sedimentary rocks, especially if they contain or contained organic matter. It is also a very common hydrothermal mineral.
