%X A series of alkan-2-ones,alkan-3-ones and alkan-4-ones were found and identificated with mass spectra in a vertical profiles of biogenic gas source rocks in the Quaternary of the Qaidam basin, and the relative contents of different carbon number alkan-2-ones were calculated according to the chart of mass chromatogram of samples. The distribution character of alkan-2-ones,alkan=3-ones and alkan-4,ones is similar in one sample; and there is a great change in the distribution of alkan-2-ones in the vertical pro- files. The CPI of alkan-2-0nes ranges from 1.20-1.80, and value of L/H ranges from 0.30-1.61. Based on the characteristics of alkan-2-ones distribution and biomarker parameters, and combined with the geological background of the samples, the source of aliphatic ketones in biogeneic gas source rock in the Quaternary of the Qaidam Basin were discussed, we think that the aliphatic ketones derived from biomass in saline-subsaline lacustrine deposits of the Quaternary of Qaidam basin or from the biodegradation of alkanes by bacterial community.
