| Abstract: | Through studying of magnetotelluric sounding on Qushui-Duodi profile in Lhasa basin, the deep structures of Lhasa basin are reconstructed. Granite is extensively distributed in the upper crust. The depth of Moho surface is about 70 kilometers. There is a high conductivity layer in the crust, the top surface of the layer rises gradually from south to north, and the thickness of the layer is 20~30 kilometers. There exists a deep fault near Sangda area. |
