摘要
The Maza Tagh fault zone lies in the central Tarim Basin, about 300 km long in the west-east direction. Lower Pleistocene section is a complete sedimentary sequence and well-exposed section in the south of Maza Tagh Mountains. 16 sites 130 samples were collected from grey yellow mudstones and sand-mudstones. Rock magnetism show the magnetite is the principal carriers of natural remnant magnetization. The lithology features of the Lower Pleistocene strata suggest that the paleo-climate is warm and wet. The transfer of paleo-current directions imply that the existence of paleo-great lake in the central Tarim Basin at Lower Pleistocene and the dramatic uplift of the western of the western Kunlun Mountains at the end of Pleistocene.
