Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron disulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic and sedimentary rocks worldwide.he only common mineral that has properties similar to pyrite is marcasite, a dimorph of pyrite with the same chemical composition but an orthorhombic crystal structure. Marcasite does not have the same brassy yellow color of pyrite.
