Abstract: The formation process of late Mesozoic petroliferous basins in the NE China can be divided into two development stages which were formed in different tectonic environments.The first-stage basins(J₁₊₂)belonged to faulted basins.and the second-stage basins(J₃K)were rift basin group with NE strike.During Late Cretaeeous.Songliao basin became a large-scale lake basin.which became a large continental petroleum-rich basin.The sinistral strike-slip movement of the Tan-Lu fault and the changes of tectonic stress field resulted in many parallel faults and a series of inversion structures within Songliaa basin.These structures provided excellent traps for oil and gas accumulations.Based on the tectonic development history of the basins,filling characteristics and thermal evolution history.the petroliferous systems of late Mesozoic basins in the NE China can be classified into single-source systems and super-impaled systems with multiple sources,*each of them has its own distribution characteristics.
