Sphalerite Wikipedia

Sphalerite ((Zn, Fe)S) is a mineral and ore of zinc. It consists largely of zinc sulfide in crystalline form but contains variable iron; when iron content is high, sphalerite is an opaque black variety called marmatite. Sphalerite is found in association with the minerals galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite and fluorite.
