Trofimuk Institute of Petroleum Geology andGeophysics of the Siberian Branch RAS, Novosibirsk, Russia, KontorovichAE@ipgg.nsc.ru*Institute of Volcanology and Seismology of the Far Eastern Branch RAS,Petropavlovsk‐Kamchatsky, RussiaAuthors selected and examined oil shows from the caldera of the Uzon volcano(Kamchatka). The hydrocarbon type content of oil shows is dominated by hydrocarbons (HC)(90‐93%). The concentration of saturated hydrocarbons by weight in them is two times asmuch as that of aromatic ones. The concentration of heterocyclic compounds is 7‐10%. Fewasphaltenes are present in the examined samples (< 0,3%). The composition of saturatedand aromatic hydrocarbons of oil shows in the Uzon volcano caldera shows that they havebeen derived from lipids of land plant remains brought into sediments (the ratio of steraneconcentrations С 29 /С 27 >2,5, tricyclane index 2(С 19 +С 20 )/С i (i = 23, 24, 25, 26)>1,5, relativelyhigh concentration of triaromatic steroids), aquabionts, inhabitants of caldera sediments andbottom waters (the ratio n‐С 27 /n‐С 17
