Based on the relationship of stratum uplifting(or sedimentation) and rising(or falling) of paleotemperature,and the thermal history simulation of apatite fission track,beginning time of Cenozoic unconformity and sedimentation of Songliao Basin was confirmed here.

On the basis of apatite fission track thermal history modeling results of intrusive rock samples from Yichang and Tongshan in the periphery of Jianghan Basin,we think that the samples have come through four stages of cooling with different cooling rates since Mesozoic,indicating the constant uplifting since the Indosinian period in the periphery of Jianghan Basin.
