New Project to Explore Deep-seafloor Mineral Deposits

2018-12-18  Deep-seafloor mineral deposits can provide vital new metals for emerging technologies, including those that will reduce greenhouse gas emissions. Many deposits were formed by hot springs on the seafloor and the vast majority of these now lie under a blanket of marine sediment.

Feb 21, 2014 There, on the seafloor, mineral deposits created by hydrothermal vents hold a wealth of metals. Mining just 11 hectares of the seafloor at this loion (a region equal in area to about 21 U.S. football fields) could produce about $900 million worth of copper, Smith says. Other metals in the deposits would bring in even more money.

Deep-Ocean Mineral Deposits - Elements

A key question for the future management of the oceans is whether the mineral deposits that exist on the seafloor of the deep ocean can be extracted without significant adverse effects to the environment. The potential impacts of mining are wide-ranging and will vary depending on the type of metal-rich mineral deposit being mined.

Hydrothermal vent - Wikipedia

2019-10-13  A hydrothermal vent is a fissure on the seafloor from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centers, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents.
