Mineral Deposits On The Seafloor

Seafloor Minerals - USGS

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.

Global Marine Mineral Resources - USGS.gov

A wide variety of minerals form through hydrothermal activity, but seafloor massive sulfides are formed from reduced sulfur and may be enriched in copper, zinc, iron, gold, and silver. Hydrothermal vents exist along mid-ocean ridge spreading centers, extensional systems associated with subduction zones, volcanoes, and intraplate hotspots.

31/01/2003  The first hydrothermal mineral deposit was found in the 1960s in the northern Red Sea, where sea-floor spreading separates Africa from the Saudi Arabian peninsula. Hydrothermal solutions discharge as density-stratified, metal-rich brines and precipitate metalliferous sediments in basins along the spreading axis. In 1979, the Saudi-Sudanese Red Sea Commission used

Seafloor mining: the DeepGreen method

“Seafloor Polymetallic nodules are mineral deposits found on the seafloor that can look like fields of potatoes,” says DeepGreen head of environment and social performance Dr Samantha Smith. “Nodules are often rich in metal, and the key here is that they are multi-metal. So they can contain nickel, manganese, cobalt and copper, as well as other metals.” By collecting these

Generation of Seafloor Hydrothermal Vent Fluids and ...

In the nearly 30 years since the discovery of hydrothermal venting along open-ocean spreading centers, much has been learned about the generation of vent fluids and associated deposits. The hot, reducing, metal-rich, magnesium- and sulfate-poor hydrothermal fluids that exit “black smoker” and “white smoker” chimneys are formed through interactions of seawater with
