- Аннотация: Modern carbonate formation in Laspi Bay beach area is a product of processes of interaction the lithosphere, hydrosphere, atmosphere and biosphere (South Coast of Crimea). An example of a cold shelf degassing is the outputs gases from the underwater part of the beach area Laspi Bay. The composition of gas bubbles fluid presents methane, ethane, propane and hydrogen sulfide, it testifies to its deep genesis. The results of geological research outputs cold degassing of hydrocarbons in the underwater part of the beach area of the bay Laspi confirm that carbonate structures with oasis of life is formed in the active geodynamic environment around the gas jets. It is represented by gravelstones and pebble beds that are cemented with aragonite and calcite. The formation of carbonate cement conglomerates in the beach area is connected with vital activity micro –and macro fauna and flora local biocenosis. High speed cementation of pebble allows to suppose that modern carbonate structures from great depths of the Black Sea and other have a younger age. The authors hypothesize that archaea receive oxygen (for the formation of organic substances and oxidation of carbon and sulfur) at the expense the decomposition of water. In the future, this method of producing oxygen was adopted by cyanobacteria and fauna. Therefore, at the bottom of the Black Sea hydrogen sulphide zone at bacterial mats with modern degassing aerobic fauna finds life are possible.
