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).

Sphalerite occurs interstitial to the pyrite. A crude bedding or lamination is locally discernable between these two sulphide minerals. Near solid coarse grained sphalerite zones occur locally as bands or boudins that strongly suggest that remobilization took place during metamorphism.[2017 TR, p. 78]
