Zinc sulfide occurs as two polymorphs, cubic sphalerite and hexagonal wurtzite. Sphalerite is the stable phase at low temperatures and is a fairly common trace mineral in sulfidic sediments. It forms as a discrete solid phase since Zn is not incorporated to any significant extent within sedimentary pyrite (Luther et al., 1980, Morse, 1994 ).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.

Sphalerite and galena occur in very minor amounts, particularly in Cu-rich footwall mineral zones and as late, cross-cutting veins in association with late shear zones and faults (Table 4.3). Sphalerite and galena also occur as interstitial grains in massive sulfide and adjacent to silicate inclusions.
