Alkanes in a number of hydrothermal systems of the Russian Far East

Abstract

The article presents the results of research dedicated to saturated hydrocarbons in the hydrothermal systems of the Russian Far East. The research has revealed significant differences in molecular-mass distribution of alkanes in the hot springs with different temperatures and origin. Alkanes, contained in the most high-temperature fluid from deep wells in Kamchatka peninsula , have the thermogenic genesis. At the same time alkanes, contained in the continental hot springs, are formed as a result of chemical re-synthesis of organic residues. In the least hot waters, as well as in cold underground and surface waters, hydrocarbons with bacterial and vegetable genesis have been revealed.
