| A Study of the Crustal Tectonic Evolution in Basin-Mountain Areas of Northwest China in the Light of Xinjiang Geotransect |
| Based on the achievements of Geotransect from Dushanzi to Quanshuigou of Xinjiang, this paper deals with the crustal structure and tectonics of such areas of southern Xinjiang as Junggar basin, Tianshan Mountains, Tarim basin and Kunlun Mountains. Some characteristics of the crustal structure and tectonic evolution history of basin-mountain areas in Northwest China are also discussed. The author holds that the tectonic movement of the crust in the basin-mountain areas of Northwest China is mainly attributed to the unhomogeneity of the crust and the upper mantle, including the unhomogeneity of structures and components. It is emphasized in this paper that the present tectonic features of basin-mountain areas are products of Cenozoic crustal activities. Its formation started in Mesozoic or even Late Paleozoic. It is therefore a continuous historical process. Nevertheless, their present frameworks are quite different from those in Mesozoic. |
