Description
Summary:cs A zone of submarine gas seepages was discovered on the seafloor of the Kamchatsky Gulf (East Kamchatka)Tuas plumes have been detected in the upper part of the Kamchatsky canyon within a depth range of 40-250 m. Sandstones with carbonate cementation were recovered from the seafloor near the seep locations. Cement occurs as calcite and Mg-calcite. the isotopic composi-tion of carbon from carbonates (8'3C =-62%o PDB provides grounds for believing that they originate as a result of methane oxidation.
