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 ...
