The pyrite group of minerals is a set of compounds, each a disulfide of at least one metallic element.[1][2] They are named for the most common of their kind, FeS2, usually known as pyrite but sometimes emphasized as iron pyrite, and often informally called fool's gold for its history of being taken for high-grade gold ore.
Examples include:
- Cattierite (CoS2), a cobalt compound
- Vaesite (NiS2) (incorporating nickel), and sometimes found together with cattierite in the Democratic Republic of Congo, or with ores of chalcopyrite (CuFeS2), and sometimes containing both copper and iron pyruites
- Pyrrhotite, pyrite compounds ranging from the magnetic FeS through nonmagnetic variants as much as 20% deficient in sulfur.
