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.

2013-11-1 · Seafloor massive sulfide (SMS) deposits form in a suite of hydrothermal settings across a range of depths. Many deposits are of a tonnage and mineral grade comparable to land deposits and are attractive to mining companies. Economically viable deposits can be either active or inactive, with different biological communities present at each.

2016-7-1 · Seafloor massive sulfide (SMS) deposits have significant development potential. In 2011, the China Ocean Mineral Resources Research and Development Association (COMRA) and International Seabed Authority (ISA) signed a contract to explore a 10 000 km 2 region of the seafloor along the Southwest Indian Ridge (SWIR) containing hydrothermal sulfides. As regulated by the contract, China

Polymetallic massive sulfides on the modern seafloor have been found in diverse volcanic and tectonic settings at water depths ranging from about 3700 to 1500 m. These deposits are located at fast-, intermediate-and slow-spreading mid-ocean ridges, on axial and off-axis volcanoes and seamounts, in sedimented rifts adjacent to continental ...

Simultaneous leaching of seafloor massive sulfides (SMS) from Loki’s Castle on the Arctic Mid-Ocean Ridge (AMOR) and polymetallic nodules (PN) from Clarion Clipperton Zone (CCZ) of the Central Pacific Ocean was studied. Leaching tests were conducted using sulfuric acid and sodium chloride, at a temperature of 80 °C for 48 h under reflux. The effect of PN-to-SMS ratio was examined.
