- Аннотация: Methane is an important greenhouse gas playing a major role in dynamics of climate system. This study focused on methane concentration and genesis in various types of ground ice. The data on quantity and genesis of methane was collected from Holocene and Pleistocene ice wedges, and from the large massive tabular ice bodies. The Holocene syngenetic and epigenetic ice wedges have methane concentration below 1,6pm and the Pleistocene syngenetic ice wedges have methane concentration below 4,5pm. Isotopic composition of methane in gas bubbles Methane entrapped in tabular ice bodies has bacterial genesis δ13С (СН4) -71‰-58‰ and show considerably higher concentration up to 23pm. Anaerobic environment characteristic of tabular ground ice formation and high organic content of solution provided favorable conditions for methane producing bacteria.
