Abstract

Bimodal distribution was explored for n-alkanes in an oilsand sample from well Lunnan 14, Lunnan oilfield, Tarim Basin, NW China. GC-C-IRMS analyses indicated that the stable carbon isotopic compositions for nC ₂₃～nC ₃₂ n-alkanes (-32.02‰～-30.90‰) were isotopically heavier than that of nC ₁₂～nC ₂₂ n-alkanes (-33.72‰～-32.84‰) which reflect the contributions of two different organic matter inputs.In the mean time, high content mono-methyl branched alkane homologues were detected during the nC ₂₃～nC ₃₂ n-alkanes which have the same or similar stable carbon isotopic compositions (-30.52‰～-31.64‰) with nC ₂₃～nC ₃₂ n-alkanes. This seems to mean that they share the same genetic scheme. According to marvelous literatures and the measured stable carbon isotopic compositions, mono-methyl branched alkanes should be derived from microorganism, thus, a suspicion was put forward for the general biological precursor of which the high molecular weight n-alkanes (nC ₂₃～nC ₃₂) were derived from higher plant.
