Hydrothermal vent Wikipedia

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.

Hydrothermal mineral deposit Wikipedia

Hydrothermal Deposits a large group of mineral deposits formed from the sediments of hot aqueous solutions that circulate deep inside the earth. Four groups of sources of the water of hydrothermal solutions are distinguished: (1) magmatic water, which separates from magmatic melts in the process of solidifiion and formation of igneous rock (2
