Abstract: 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.

Key words: Late Mesozoic, strata correlation, basin evolution
