英文摘要	The potential parent source rocks except from Upper Permian Dalong Formation (P(3)d) for Upper Permian and Lower Triassic solid bitumen show high maturity to overmaturity with equivalent vitrinite reflectance (ERo) from 1.7% to 3.1% but have extractable organic matter likely not contaminated by younger source rocks. P(3)d source rocks were deposited under euxinic environments as indicated by the pyrite delta S-34 values as light as -34.5% and distribution of aryl isoprenoids, which were also detected fromthe Lower Silurian (S(1)l) source rock and the solid bitumen in the gas fields in the west not in the east. All the solid bitumen not altered by thermochemical sulfate reduction (TSR) has delta C-13 and delta S-34 values similar to part of the P(3)l kerogens and within the S(1)l kerogens. Thus, the eastern solid bitumen may have been derived from the P(3)l kerogens, and the western solid bitumen was likely to have precracking oils from P(3)l kerogens mixed with the S(1)l or P(3)d kerogens. This case-study tentatively shows that delta C-13 and delta S-34 values along with biomarkers have the potential to be used for the purpose of solid bitumen and source rock correlation in a rapidly buried basin, although further work should be done to confirm it.
