Abstract The results of the lithological and geochemical analysis of bottom sediments collected in the southwestern part of the Kara shelf in the area of development of gas-saturated deposits in a paleovalley at a depth of 112 m are presented. It has been established that the accumulation of the Holocene marine sediments occurred under conditions of fluid inflow as a result of degradation of permafrost and destruction of its gas hydrates, which are apparently suppliers of isotopically heavy waters to the studied strata.
