摘要
In this paper, the authors studied the characteristics and evolvement of thrust-nappe structure in the area of Xiaosongshan-Zongbieli in the north section of Helan Mountains in Ningxia. The methods of geological route observation and tectonic mapping, and synthetizing analysis to the micro-group are used to estimate whether the thrust-nappe structure have occurred in Xiaosongshan area. It is found that the system of Xiaosongshan-Zongbieli thrust-nappe structure is mainly composed of Xiaosongshan-Zhengyiguan fault belt, Hong Ling and Chaidalangjing fault plane.
