To analyze the richness ,type and maturity of organic matter of South Qilian permafrost of Middle-Lower Jurassic Yaojie formation , rock pyrolysis test was conducted .The average organic carbon content is 7.141%and the average free hydrocarbon is 0.432 mg/g.The pyrolysis hydrocar-bon is 4.636 mg/g and the average oil potential rate is 5.068 .The average residual carbon is 29.04 mg/g and the yield index is 0.273 .The average effective carbon is 0.421%and hydrocarbon index is 47.085 .The type of organic matter are mainly type Ⅱ2 and typeⅢ.The thermal evolution of organic matter reached mature or high mature stage .It means that the mud rock is rich in organic matter,and the Middle-Lower Jurassic is the potential hydrocarbon source rock .
