Wisconsin Geological Natural History Survey » Sphalerite

The sphalerite readily alters to smithsonite, which forms large deposits in the oxidized zone above the sulfide masses. All of the sphalerite deposits listed below are likely places to find any of the other associated minerals. An excellent detailed description of the district is given by Heyl and others (1959).

Sphalerite mineral Britannica

Sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc. It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning “treacherous,” an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore).

Sphalerite - USGS

Mar 23, 2017  Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc uses range from metal products to rubber and medicines. Zinc alloys readily with other metals and is chemically active. On exposure to air, it develops a thin gray oxide film (patina), which inhibits deeper oxidation (corrosion) of the metal.

Sphalerite: Mineral information, data and localities.

Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).
