  • Seafloor massive sulfide deposits - Wikipedia

    2020-6-1  Seafloor massive sulfide deposits or SMS deposits, are modern equivalents of ancient volcanogenic massive sulfide ore deposits or VMS deposits. The term has been coined by mineral explorers to differentiate the modern deposit from the ancient. SMS deposits were first recognized during the exploration of the deep oceans and the mid ocean ridge spreading centers in the early 1960s.

    Seafloor massive sulfide (SMS) deposits form on and just below the seafloor along submarine tectonic plate boundaries. The deposits form from seawater that circulates through the underlying crust, is heated, leaches metals and sulfur from the surrounding rock, and then ascends and vents at the seafloor, forming sulfide mineral accumulations rich in Cu, Zn, Pb, Au, and Ag.
