Seafloor Minerals

The seafloor contains deposits of minerals that we use in everyday life such as copper, zinc, nickel, gold, silver, and phosphorus. These deposits occur as crusts on volcanic and other rocks and as nodules on abyssal plain sediment that are typically about 3 to 10 centimeters (1 to 4 inches) in diameter. A bed of manganese nodules from deep ...

Marine sediment

Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea. . Additional deposits come from marine organisms and chemical ...

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.
