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

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.

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.
