Table T4. Chemical formulae of sulfide minerals identified during Expedition 331.
Mineral | Composition |
---|---|
Pyrite | FeS2 |
Pyrrhotite | Fe1–xS |
Chalcopyrite | CuFeS2 |
Covellite | CuS |
Sphalerite | (Zn,Fe)S |
Wurtzite | ZnS |
Galena | PbS |
Tennantite | (Cu,Fe,Zn.Ag)12As4S13 |
Tetrahedrite | (Cu,Fe,Zn.Ag)12Sb4S13 |
Sulfosalt | A class of sulfide minerals in which a semimetal (As or Sb) takes the place of one or more S atoms in the structure. Tennantite and tetrahedrite are important examples, and Pb and Ag commonly form sulfosalts. |
