Sphalerite rock
Sphalerite with higher purity often appears as yellow, transparent crystals instead. The sphalerite contained in Indiana varies greatly in quality. Pure, nearly white crystals are found at times while in others it’s the classic, glossy black formation of low-grade, high-iron sphalerite.In places scattered across the region, small deposits of galena (PbS) and sphalerite (ZnS), along with quartz and traces of pyrite (FeS 2) and chalcopyrite (CuFeS 2), are present.
