Volcanogenic Massive Sulfide Occurrence Model - USGS

Massive ore in volcanogenic massive sulfide deposits consists of greater than 40 percent sulfides, usually pyrite, pyrrhotite, chalcopyrite, sphalerite, and galena; non-sulfide gangue typically consists of quartz, barite, anhydrite, iron oxides, chlorite, sericite, talc, and their metamorphosed equivalents.

VOLCANOGENIC MASSIVE SULPHIDE DEPOSITS

Volcanogenic massive sulphide (VMS) deposits are also known as volcanic-associated, volcanic-hosted, and vol-cano-sedimentary-hosted massive sulphide deposits. They typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic envi-ronments. They form from metal-enriched fluids associated
