This paper reports the analysis of the distribution of hydrocarbon and other gases in Mendeleev and Golovnin volcanoes and other occurrences of Kunashir Island. It was shown that, in addition to methane, the solfatara gases and gases dissolved in thermal waters contain ethane, propane, and butane. The volume concentration of methane in gas samples was no higher than 0.4 vol %. Carbon isotopes were analyzed in methane, ethane, and carbon dioxide in free and dissolved states. The hydrocarbon gases of Kunashir I. are of the thermogenic and metamorphogenic types, and their distribution depends on the position of springs relative to the eruptive centers of the volcanoes. Thermogenic gases are probably products of the high-temperature transformation of sedimentary organic matter buried during the formation of volcanic edifices. General gas geochemical characteristics are presented for Kuril volcanoes, and it was found that hydrocarbon generation in the sediments of the Kuril Basin increases toward volcanic edifices. 相似文献
