Marcasite mineral Britannica

Marcasite is found with lead and zinc minerals in metalliferous veins, as at Galena, Ill., U.S., and at Clausthal Zellerfeld and Linnich, Ger. Marcasite, which has the same chemical formula as pyrite (FeS 2) but crystallizes in the orthorhombic instead of the isometric system, alters upon weathering to ferrous sulfate and sulfuric acid.
