The response of the Tibet uplift since Lower Pleistocene in the centre of Tarim basin. Acta Petrologica Sinica ，27 (11):3487 － 3498 Abstract The pulse uplift of Tibetan Plateau is a compressing uplift event resulted from the inner continent subduction of Indian Plate since ca. 55Ma. The uplift of northern Tibetan plateau occurred in the Late Cenozoic definitively influenced the tectonic formation and the large scale aridity. The Mazartagh fault zone lies in the central Tarim basin (latitude :N38° 40. 911 ，longitude :E80 ° 18. 484 )，about 300km long in the west-east direction. Lower Pleistocene section is a complete sedimentary sequence and well- exposed section in the south of Mazartagh Mountain. This study extends this section ，and 9 sites 90 samples were collected from grey yellow mudstones and siltstone. The high resolution magnetostratigraphic results and magnetic susceptibility suggest the age of these strata is from 2. 2 ～ 0. 1Ma. Magnetic susceptibility was measured on 209m depth surface outcrop of
