Compositional zoning in sphalerite crystals
Sphalerite, the cubic polymorph of ZnS, exhibits a wide range of compositional variations in natural specimens (e.g., Pattrick et al. 1993, 1998; Axelsson and Rodushkin 2001) where other metal cations can replace Zn in the tetrahedral site. One consequence is that sphalerite is the major source not only of Zn, but also of Cd, In, Ge, and Ga.
