Abstract：West Kunlun orogenic belt is located in the northwest margin of the Qinghai-Tibet Plateau,and in the southwest edge of Tarim basin.This belt is an important part of the central orogenic belt.It has experienced a long and complicated tectonic-sedimentary evolution.This paper presents lithostratigraphy of outcrops in five stratigraphic subregions and their corresponding sedimentary basin types in West Kunlun orogenic belt.The evolutionary history of sedimentary basins in West Kunlun is ex-plored and divided into following three stages from Neoproterozoic to Mesozoic in this study:(1)the stage of continental break-up and the formation of oceanic crust in Neoproterozoic;(2)the stage of plate mechanism evolution in Early Paleozoic-Middle Triassic;(3)the stage of evolution in intracontinental since Late Triassic.
