详细信息   
摘要

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 Pernian-Early Triassic period, the particle size, distribution, morphology, composition changes of Turpan-Hami 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 Turpan-Hami Basin, it is concluded that the re-uplift time of Bogda Mountain took place at late Xishanyao Formation, and became the north source supplying area of the Turpan-Hami Basin.
