This paper presents the investigation results of geodynamic, geothermal and geochemical conditions of gas emission zones in the anoxic Black Sea Basin. Gases are manifested in the form of seeps, fountains, mud volcanoes (MV), gas hydrates and authigenic carbonates. Several thousand gas seeps and more than 80 MVs have been found in the Black Sea Basin. Most of them are associated with fault zones, abyssal fractures, shale diapir and others zones of neo-tectonic activity. Gas seeps occur mostly on
