The metallic minerals of the Pacific Seafloor SpringerLink

The metallic minerals existing on the seafloor of the Pacific Ocean display a great range of variations in their chemical and physical properties. These deposits are considered as an important source of raw material because of their contents of Ni, Cu, Co, and Mn. The two dominant types of deposits are ferromanganese encrustations and nodules. The nodules, being more important with regard to ...

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.
