Minerals and Gemstones Found In Wisconsin. 1. Sphalerite. Sphalerite is the primary ore of zinc, taking the form of cubic crystals of zinc sulfide. It’s a common find in areas that previously had hydrothermal vents in the past, and it’s a good indication that other related minerals are nearby.Sphalerite is a mineral, mixed with zinc and iron sulfide. The chemical formula of Sphalerite is (Zn, Fe)S. The dispersion of sphalerite (0.156) is three times …Sphalerite is a zinc sulfide (ZnS) mineral with bronze-black ( Fig. 1.49) and honey-yellow color. The mineral contains 67% zinc metal in its natural pure form. Majority of the large SEDEX (Sedimentary Exhalative) type zinc deposits are associated with lead, copper, silver, cadmium, nickel, and gold mineralization.

Sphalerite ((Zn,Fe)S) is a mineral that is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains ...Sphalerite and wurtzite are polymorphs. They share the same chemical formula (ZnS), but have different crystal habits. Sphalerite has an isometric crystal structure, while wurtzite has a hexagonal structure. These two …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 ).
