摘要
On the basis of regional investigation (1:250 000) and field geological mapping. The authors reached theconclusion that there is a huge thrust nappe belt along the Mongolia Temple-Mount Panyangshan-Ulanheya. The Seertengshan Group and Upper Archaean granitoid were thrusted onto the Sinian limestone and Paleozoic clastic rock. The thrust nappe belt is actually a typical duplex, and it is consisted of plentiful structural styles: such as klippes, tectonic windows, roof thrust, floor thrust and horses etc. Moreover, the detailed analysis of the thrust nappe structure indicates that the thrust direction is south and southwest. The events occurred in Late Permian. The nappe displacement is estimated more than 7.1 kilometers. The authors considered that the thrust nappe belt was from the collisional orogeny of the North China Plate and the Siberian in Late Permian, and it is a part of the northern margin of the North China Plate.
