Crystal-enclosed organic matters,important hydrocarbon-generating matters,arewildly present in the carbonate rocks of the Tarim Basin. The peak of secondary hydrocarbon generation occurs at R。 1. 25%. The pyrolysis peak temperatures of dolomite crystal-enclosed organic matters and calcite crystal-enclosed organic matters are 490￣520℃ and 570￣600℃ respectively. The maturity of crystal-enclosed organic matters is lower than that of bitumen A. Both are different in the distribution of biomarkers. According to this fact the oilsource rock correlation and tracing of migration direction can be made.
