Electrical Structure of Crust and Upper Mantle Of the Western Tibet plateau by MT Data
The magnetotelluric (MT) survey along the Zhada -Quanshui Lake profile on the western Tibet plateau shows that the study area is divided into three tectonic region by the Yalung Tsangpo and Bangong-Nujiang sutures. From south to north these are the Himalayan terrane, Gangdise terrane, and Qiangtang terrane. In the study area, there are widespread high-conductivity layers in the mid and lower crust, the top layers of which fluctuate intensively. The high-conductivity layer within the Gangdise terrane is deeper than those within the Qiangtang terrane and the Himalaya terrane, and the deepest high-conductivity layer is to the south of the Bangong-Nujiang suture. The top surface of the high-conductivity layer in the south of the Bangong-Nujiang suture is about 20 km lower than that in the north of it. The high-conductivity layer within the Gangdise terrane dips toward north and there are two high-conductivity layers within the crust of the southern Qiangtang terrane.
