Mud-volcanic deposits of methane gas hydrates in the Black Sea

This paper discusses the formation of a special mud-volcanic type gas hydrate accumulation in deep-water part Black Sea. The main conclusions are based on results geological and geophysical studies mud volcanoes carried out course numerous scientific cruises between 1970-2015. Comparison Sea submarine with their on-land analogues indicates possible use compensatory depressions, called “recessed synclines”, accompanying volcanoes, which is revealed prospecting exploration mineral deposits. In sea they represented by ring deposits methane hydrates.
