  1. Sulfide Minerals • Here you will find a short summary of the sulfides that you are studying in lab

  2. Important Sulfide Minerals • Pyrite FeS2 • Aresonopyrite FeAsS • Sphalerite ZnS • Chalcopyrite CuFeS2 • Covellite • Galena PbS • Pyrrhotite Fe1-xS • Cinnabar HgS • Molybdenite MoS • Enargite • Oriment • Stibnite

  3. Important Sulfide Minerals • Sulfide minerals have a restricted composition range and solid solutions are rare • Most sulfides (except sphalerite) are opaque semiconductors with metallic luster

  4. Sulfide parageneses • Most sulfides are deposited by hydrothermal solutions (e.g., galena, sphalerite, chalcopyrite). Metal cations are transported by cl-1 complexes at high temperature.

  5. Sulfide parageneses • Some are primary minerals in igneous and metamorphic rocks (e.g., Molybdenite, pyrrhotite) and crystallize from the magma. • Sulfides also may form, in sediments under the reducing conditions resulting from decay of organic matter.

  6. Pyrite • Cubic • Most widespread sulfide mineral. Found in all geological environments • Marcasite is a related polymorph formed at low Temperature.

  7. Pyrrhotite • Found as accessory phase in igneous rocks.

  8. Chalcopyrte • Primary copper mineral,in porphyry-copper deposits. • Most widespread copper mineral

  9. Arsenopyrite • Primary arsenic mineral

  10. Molybdenite • Primary Molybdenum ore • High temperature deposite

  11. Sphalerite • Primary ore mineral for Zn

  12. Galena • Primary ore mineral for Pb
