Iron pyrite

Description

Primarily occurs as a yellowish mineral with a metallic luster called Pyrite. Iron disulfide also occurs as that mineral Marcasite. Major sources for iron pyrite include sites in India, Turkey, and Russia. It was called fool's gold because its color and metallic sheen often is mistake for gold. Polished pieces of iron pyrite have been used for necklaces and bracelets. Ethanolamine thioglycollate treatments have been used to minimize the decomposition of pyritic specimens (Cornish 1984).

See also Pyrrhotite.

Synonyms and Related Terms

iron (II) disulfide; iron pyrite; pyrite; fool's gold; martial pyrite; mundic; factitous pyrite; Pyrit (Deut.); pyrite (Fr.); pyriet (Ned.); piryt (Pol.); pirita (Port.);
