The molecular carbon isotope composition (δ13Cmole) of n-alkanes, isoprenoid hydrocarbons, isoalkanes, anti-isoalkanes and hopanes in the oils and source rocks from the West Liaohe Depression are systematically studied. The variations in the δ13Cmole values of the four series of biomarkers are well correlated and indicate that the biological and environmental constraints on δ13Cmole values in various oils vary systematically and the δ13Cmole values predominantly present the features of sedimentary-organic facies. Thus the oils from the West Liaohe Depression are well classified based on δ13Cmole values of these series of biomarkers and the differences between Es4 and Es3 sources are described in detail. The n-alkanes are enriched in 13C by 0.5‰~5.0‰related to isoprenoid HCs, and pristine is enriched in 13C by 0.4‰~1.4‰related to phytane. These indicate methanogenic bacteria should make important contribution to phytane. Regular isoprenoid HCs, relatively enriched in 13C by 0.5‰~2.0‰, should be different from that of the series of phytane in source. Isoalkanes and anti-isoalkanes are probably related to cyanobacteria input in some extent as evidenced by their relatively positive δ13Cmole values. The important differences in δ13Cmole value between and C30 hopanes (10‰~12‰) strongly indicate that the precursors of hopanes were derived from two or more organisms, such as cyanobacteria, methyltrophic or some other heterotrophic bacteria. The most 13C-depleted C30 hopanes (-61.2‰~-51.8‰) in Es4 oils and source rocks were derived from methyltrophic bacteria living at the anaerobic/aerobic boundary of the lake with strong water stratification, while the most 13C-enriched hopanes (-37.5‰~-33.4‰) in Es3 oils and source rocks should be contributed partly by cyanobacteria. The abnormally positive δ13Cn-alk, δ13Cisoalk as well as δ13CHop in the oils sourced from Es3 Formation may well indicate that cyanobacterial biomass input to the Es3 source rocks is very important. In addition, the relative high δ13Ckero values and enrichment of 4-methyl-steranes in Es3 oils well indicate that the blooming of dinofragellates occurs seasonally and makes an important contribution to the organic matters.
