中文摘要：

辽东南地区晚中生代地层发育不甚完全，具有两期盆地叠合演化的特征，即早中侏罗世和早白垩世两个演化阶段，经历了2次伸展裂陷和2次挤压反转。在详细研究辽东南地区各盆地岩石地层序列、生物化石组合特征、年代地层格架以及区域地层对比的基础上，讨论了盆地的演化阶段和演化规律，指出是古太平洋板块向东亚大陆边缘不同方向的俯冲与走滑，以及来自北方西伯利亚板块的持续碰撞挤压的联合构造应力场制约了中国东北地区晚中生代盆地的裂陷过程和构造反转的演化，进而为揭示华北克拉通晚中生代岩石圈演化的动力学机制提供参考依据。

英文摘要：

The Late Mesozoic strata in the southeastern Liaoning were not well developed, but it shows that the basins have two evolutional stages, i.e. Early- Middle Jurassic and Early Cretaceous, which include two extension events and two contracting reversion events. Based on the studying of petrologic strata sequences, the characters of the biostratigraphic assemblages, the chronostratigraphy in the southeastern Liaoning and regional stratigraphical correlation, the basin evolution phases and patterns have been discussed. The Paleo-Pacific Ocean plate subduction to the eastern Asia continental margin and the Siberia plate extrusion to the south controlled the subsidence processes and the tectonic reversions of the Late Mesozoic basins in the Northeastern China. These may have some elicitations on studying the Late Mesozoic lithosphere evolution and geodynamics setting of the North China craton.
