Abstract:

 The discovery of deepsea hydrothermal vents and associated biological group is one of the most important scientific achievements in global ocean science in the last 20 years. Around the Black Smoker, there is an extreme environment with hightemperature, highpressure, darkness, hypoxia, sulfur, etc., and there is a special biological community in the deepsea. As the primary producers, thermophilic bacteria and archaea not only affect the deposition of minerals around the vents, but also directly or indirectly affect the dissolution, adsorption, extraction, and transformation of mineral elements, which causes the generation of Fe, Mn, nonferrous metal oxide, sulfide, silicate and carbonate minerals and compounds in precipitation. It is important for the deepsea mineral deposit enrichment.

Key words: hydrothermal vents；biological mineralization, oreforming fluids；mineralization
