AbstractThe Pamir plateau is the center of the confluence of the five mountain ranges, known as the western Himalayan syntaxis. It is inaccessible to the human being due to the high mountains and steep valleys. In this paper, we study the deep crustal structure and regional geological structure of the Pamir plateau region using two NNW and NEE trending crossing profiles with 1620 km in length, on which the limited ground gravity, artificial seismic data and satellite gravity data are available. Results show that the crustal thickness (the depth of Moho) in the central Pamir plateau is about 70 km, overall with a thinning trend (shallower) from the center to the rim, about 50 km in the surroundings of Pamir. This area is characterized by intense tectonic activity and obvious variation of crust and mantle structures.
