Hydrothermal vent formation
WebHydrothermal vents. Form where hot water passes up through the ocean floor, as it cools, dissolved minerals precipitate out. Found at deaths of 1500 to 4000 m and a pressure in excess of 200 to 300 atm. Where are hydrothermal vents found? They are found along the divergent plate tectonic boundaries in the deep ocean. Web23 jul. 2024 · A very small sulfide rock from a hydrothermal vent chimney in the deep sea is likely to be ‘massive.’ Because the focus of this review is ecological, use of the term ‘inactive sulfide’ should be taken to encompass both the biological community of interacting organisms and their physical environment.
