Certainly, for CO 2 emissions, mining one deep-ocean mineral deposit for three or four metals would have a lower CO 2 footprint than that of three or four terrestrial mines each producing one metal.
Sedimentary Exhalative (SEDEX) Deposit
Definition and Characteristics: Formation: SEDEX deposits are formed through the interaction of hydrothermal fluids with sediments on the ocean floor. These fluids, rich in metals, are expelled from the Earth's crust and rise through the sedimentary layers, depositing minerals as they cool.; Minerals: The primary ore minerals found in SEDEX deposits …
Black smokers | Geology, Formation » Geology Science
Black smokers, also known as hydrothermal vents, are underwater geothermal features found on the ocean floor. They are characterized by their dark appearance, caused by the presence of minerals and sulfide deposits that are expelled from the vents along with hot, mineral-rich fluids. Black smokers are typically located in areas where tectonic plates are …
