Sphalerite - Wikipedia

Sphalerite Zn, FeS is a mineral that is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. When iron content is high it is an opaque black variety, marmatite. It is usually found in association with galena, pyrite, and other sulfides along In the crystal structure, zinc and sulfur atoms are tetrahedrally coordinated.
