Abstract

we analyzed the characteristics and evolution of thrust nappe structure in Dashuigou area in the middle part of Helan mountain with the methods of geological observations and structural mapping. It consists of Ruqigou-Dashuigou fault and Gaogougoukou fault. Both of them are low angle imbricate thrust nappe fault, and the stress directions are NWW. Based on the comprehensive analysis and the results of previous studies, we concluded that the Dashuigou thrust nappe was formed at the Yanshan-Himalayan stage. Its formation time was consistent with the thrust nappe of the whole Helan Mountain.
