Isotope and geochemical parameters of hydrocarbon gases in bottom sediments of the shelf of the East Siberian Sea

摘要

The research results on gas geochemistry of hydrocarbon gases in bottom sediments of the East Siberian Sea are presented. The key isotope and geochemical parameters of syn- and epigenetic hydrocarbon gases are determined. The correlations between the molecular masses of hydrocarbon fractions and the carbon isotope composition on hydrocarbon gases of various origin are revealed.
