Foolâs Gold for April Foolâs Day. âFoolâs Goldâ is technically known as pyrite or iron sulfide (FeS2) and is one of the most common sulfide minerals. Sulfide minerals are a group of inorganic compounds containing sulfur and one or more elements. Minerals are defined by their chemistry and crystalline structure.
Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils. Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold.Gold and arsenic occur as a coupled substitution in the pyrite structure. In the Carlinâtype gold deposits, arsenian pyrite contains up to 0.37 wt% gold.his mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal. Pyrite is the most common of the sulfide minerals.
