Sphalerite is a sulfide mineral with the chemical formula (Zn, Fe)S. [5] It is the most important ore of zinc . Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative , Mississippi-Valley type , and volcanogenic massive sulfide deposits.
Sphalerite, the more common polymorph of zinc sulfide Wurtzite, the less common polymorph of zinc sulfide. ZnS exists in two main crystalline forms. This dualism is an example of polymorphism. In each form, the coordination geometry at Zn and S is tetrahedral. The more stable cubic form is known also as zinc blende or sphalerite.

English: Black tetrahedral crystals of sphalerite up to 8 mm in size across this matrix (4.5 × 3.0 × 2.0 cm) with chalcopyrite and calcite. Found from Creede, Mineral County, Colorado, USA. Found from Creede, Mineral County, Colorado, USA.
Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc-containing ore because its concentrate contains 60–62% zinc. [ 34 ] Other source minerals for zinc include smithsonite (zinc carbonate ), hemimorphite (zinc silicate ), wurtzite (another zinc sulfide), and sometimes hydrozincite (basic zinc carbonate ). [ 36 ]
He is credited with coining the mineral terms: pyrargyrite (1831), ozokerite (1833), sepiolite (1847), halite (1847), sphalerite (1847), arsenopyrite (1847), and liparite (1847). [2] He also conducted research in the field of botany — in 1836, paleobotanist Heinrich Göppert named the plant genus Glockeria in his honor.
Hawleyite is a rare sulfide mineral in the sphalerite group, dimorphous and easily confused with greenockite. Chemically, it is cadmium sulfide , and occurs as a bright yellow coating on sphalerite or siderite in vugs , deposited by meteoric water .
Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. [5] It is trimorphous with matraite and sphalerite. [2] It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite ...
