Based on the analysis of heavy mineral assemblages from Middle Jurassic in middle-northern Turpan-Hami Basin, it’s found that heavy mineral assemblage characteristics vary from area to area. In Taoerg-Shengnan-Tunan area, its heavy minerals were mainly composed of magnetite and hematite during the whole Middle Jurassic. In Qiquanhu-Shengjin area, the main component of heavy minerals were zircon, Ti-oxides, and garnet during the deposition of the Xishanyao-Sanjianfang Formations, but the amount of magnetite increased dramatically in the Qiketai Formation. The heavy minerals in Sanbao-Lukeqin area were characterized by large zircon, Ti-oxide in the Xishanyao deposition and since the stage of Sanjianfang-Qiketai Formations, the content of magnetite and garnet increased significantly. In Sanle-Sakesang area, the heavy minerals were consisted of largely zircon and Ti-oxide during the development of Xishanyao Formation, but since the deposition of Sanjianfang Formation, the proportion of the magnetite increased remarkably. In Qiuling-Qiudong area, the heavy minerals were characterized by high content of epidote in the deposition of Xishanyao-Sanjianfang Formations and then turn to zircon, Ti-oxide in the Qiketai Formation. The variation of heavy mineral assemblages in North-Central Turapan-Hami Basin show that the uplift of Bogda Mountains in Middle Jurassic were characterized by distinct segmentation. The west segment（Ⅰ）of the Bogda has been uplifted before Xishanyao stage and was the main Provence for the Turpan Basin. By contrast, the East（Ⅲ）and middle segments（Ⅱ）of the Bogda experienced uplift and erosion at the Late Xishanyao stage-Early Sanjianfang stage and Early Qiketai stage, respectively.
