Morphotectonic study from the northeastern margin of the Pamir to the West Kunlun range and its tectonic implications.
帕米尔东北缘-西昆仑的构造地貌及其构造意义

The region from the northeastern margin of the Pamir to the West Kunlun range is an important part of the northwestern Tibetan Plateau, which is surrounded by the Kongur normal fault, main Pamir thrust-Tiklik fault and Karakax fault in the northwest, northeast and southeast, respectively. According to detailed field survey, satellite images interpretation and ASTER GDEM data analysis, it shows that: (1) the Karakax fault is a left-lateral strike-slip fault; (2) the main Pamir thrust-Tiklik fault is a thrust fault; (3) the Muji fault segment of the Kongur normal fault and the Tashkorgan fault are the right-lateral and left-lateral strike-slip faults with a significant normal component, respectively, and lastly, the Tahman fault between the Kongur and Tashkorgan faults is a normal fault; (4) ASTER GDEM data analysis, including elevation distribution and local relief and slope measurements, shows that three main terrains exist within this area: the Tarim Basin, the mountain piedmont along southwestern margin of the Tarim Basin and the northeastern margin of the Pamir-the West Kunlun range; (5) the uplift and lateral extrusion are controlled by the Indian-Eurasian collision and boundary faults of the northeastern margin of the Pamir and West Kunlun, respectively.
