Abstract：The Ertix-Xar Moron suture is located at the joint part of Siberia,North China and Junggar,and its tectonic evolu-tion has a close relationship with the opening and closing of Paleo-Asian Ocean basin.In this paper,plates the sedimentary basin types are reconstruted and define 10 basin types by an integrated research on the Paleozoic lithostratigraphy,biostratigraphy and chronostratigraphy are defined.The structure-sedimentary evolution of the study area is discussed based on the sedimentary basin-fill sequence and concluded as the following stages:(1)Early Paleozoic-Early Carboniferous subduction stage of the Pa-leo-Asian Ocean;(2)Early,Late Carboniferous collisional stage;(3)Late Carboniferous-Early Permian collision and post-col-lisional evolution stage.It is suggested that the Paleo-Asian Ocean closed from west to east like “scissors”,and the closing be-gan from the end of the Early Carboniferous (318 Ma)to the Middle Permian-Early Triassic (260-245 Ma).During Triassic, the Paleo-Asian Ocean disappeared and converted to total terrestrial environment.
