Seafloor Massive Sulfides — Mineral Resources & Tectonics
Seafloor massive sulfide (SMS) deposits, also known as hydrothermal ore deposits or black smoker vents, form when a magmatic heat source drives the circulation of seawater through the ocean crust, where it leaches metals from the rocks Metals may also be contributed by magmatic fluids that are degassing from the underlying magma chamber
GISbased Mineral Prospectivity Mapping of Seafloor
With the depletion of mineral resources on land, seafloor massive sulfide deposits have the potential to become as important for exploration, development and mining as those on land However, it is difficult to investigate the ocean environment where seafloor massive sulfide deposits are located Thus, improving prospecting efficiency by reducing the exploration search space through mineral
