When the iron content is high, sphalerite is an opaque black variety called marmatite. It was discovered in 1847 by Ernst Friedrich Glocker, who named it based on the Greek word "sphaleros" meaning deceiving due to sphalerite being hard to identify. Sphalerite is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite and fluorite. Miners have been known to refer to sphalerite as zinc blende, black-jack and
