摘要
Geochemical characteristics and its genetic implications of an oil seepage in the Keping uplift of the Tarim basin were well investigated in this paper.The results indicate that Akesu oil seepage was derived from different sources of absorbed/occluded hydrocarbons.The carbon isotopic signatures of the oil seepage,the asphaltenes and the pyrolysates of asphaltenes are consistent with that of most marine oils reported in the Tarim Basin,which clearly distinguish them from typical oils derived from Cambrian source rocks.
