| The Integrated Geophysical Observation and Research along the Xinjiang (XUAR) Geotransect and Its Surrounding Areas |
| The multifarious geophysical investigations and researches were carried out in 1996～2000 along the Xinjiang Geosciences transect. The lithospheric activities, deformation traces, basement structures and border faults of the terrains were studied. New achievements reveal that the whole transect is located in a South North compression environment. The force of compression comes not only from the Indian plate but also from the downgoing drag of the lithosphere root. The lithosphere of the Tarim basin shows rigid and uniform deformation, which enhances the transformation of force. Altyn Tagh fault extends southward into the West Kunlun orogenic belt. The southern end of Altyn Tagh fault connects with Quanshuigou fault, and cuts Kuda fault and Kangxiwa fault obliquely. The Central Tianshan terrane and the North Tianshan terrane have a common basement with the Jungar basin, and the basement tectonic framework of the South Tianshan terrain is the same as that of North Tarim. South Tarim and North Tarim are two different terrains in the nature of the basement, and their boundary fault is roughly along the 40°N line. The researches show that the Neo tectonic activity of Xinjiang is not the simple reactivation of an ancient plate. |
