Description
Summary:The work reports on the results of geochemical studies of the bottom sediments on the shelf of the East Siberian Sea. The sediments’ gas content, gas composition, and gas geochemical and isotopic characteristics are determined. Abnormal zones of distribution of methane, hydrocarbon gases, and carbon dioxide are revealed within the studied areas, along with the general geological factors affecting gas formation. Areas of distribution of hydrocarbon gases of varying origins are distinguished. The potential for oil-and-gas content is estimated.
