  • Deep sea mining Wikipedia

    Deep sea mining is a growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of 200 meters or greater Presently, the majority of marine mining efforts are limited to shallow coastal waters, where sand, tin and diamonds are more readily accessible To date, deep sea mining has been limited to There are three typesDescribe how these deposits are distributed throughout geologic time (Archean to Cenozoic) and in space (eg, midocean ridge, continental arc, backarc basin) Develop a conceptual SourceTransportTrap (STT) model for understanding the genesis of mineral deposits on Earth and their relationship to plate tectonics in time and spaceEOSC 331 · Introduction to Mineral Deposits |Mineral Deposits SK Haldar, Josip Tišljar, in Introduction to Mineralogy and Petrology, 2014 845 Black Smokers Pipe Type “ Black smokers ” pipetype deposits are formed on the tectonically and volcanically active modern ocean floor by superheated hydrothermal water ejected from below the crust The water with high concentrations of dissolved metal sulfides (Cu, Zn, and Pb) from theBlack Smoker an overview | ScienceDirect Topics
