Abstract: The Bogda Mountain located between Junggar basin and TurpanHami basin. Its uplift time has been debated for a long time and is of important geotectonic significance. Based on the information of predecessors and the study area, it is considered that the Bogda area was mainly in extensional environment between Early Carboniferous to Middle Permian; in later Pernianearly Triassic period, the particle size, distribution, morphology, composition changes of TurpanHami Basin sediments and stratigraphic contact relationship show that the initial uplifting time of the Bogda mountain took place at late Permian. According to the great changes of time and space about sedimentary facies, ZTR index and sandstone detrital compositions of Xishanyao formation, Sanjianfang formation and Qiketai formation in middle Jurassic epoch on Taibei sag of TurpanHami Basin, it is concluded that the reuplift time of Bogda Mountain took place at late Xishanyao formation, and became the north source supplying area of the TurpanHami Basin. But the maximum uplift amplitude during the Himalayan movement formed the present basinorogen pattern.
