| 摘 要： | The authors have summarized the results of their study on the isotopic composition ofChina's fossil fuels for the past 20 years. Comparatively speaking, the main frequency of thedistribution of the δ~(13)C value for coal is from -25.5 to -23.5%. The effects of thermalevolution might be neglected, however, it is obvious that the coal macerals have an effecton the δ~(13)C value. The δ~(13)C of whole coal becomes lighter with the exinite content increasing.Our studies of thermoanalogue products from coal measures show that gaseous hydrocarbonhas the lightest δ~(13)C value at the peak value which produces liquid hydrocarbon. It is similarto the δ~(13)C of coal samples. The alkane in group fraction changes more significantly with theincrease of temperature. The type of biothermocatalytic transitional zone gas might be dividedaccording to the δ~(13)C and δD research of natural gas. The δD of methane becomes heavier withthe increase of water-medium salinity. The isotopic research on light hydrocarbon m
