Sphalerite - Wikipedia

Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S and an ore of zinc. When the iron content is high, sphalerite is an opaque black variety called marmatite. German geologist Ernst Friedrich Glocker discovered sphalerite in 1847, naming it based on the Greek word sphaleros, meaning "deceiving", due to the difficulty of identifying the mineral.
