通过野外详细填图，发现天景山断裂带南盘走滑运动的前端，存在庙山和红尖山两排第四纪逆（斜）冲断裂、褶皱构造带。重点介绍了庙山断褶带中的贺家口子第四纪背斜，指出：褶皱从中更新世中－晚期首先由中部开始发育，尔后逐渐向端部扩展。根据新生代构造形迹，分析了庙山和红尖山两断褶带的成因及其与天景山断裂带的运动学关系。 Through detailed mapping in the field, we found the front of the southern disk of the Tianjingshan fault zone and there are two rows of Quaternary reverse (oblique) thrust faults and fold structures along Miaoshan and Hongjianshan. Focusing on the Quaternary anticline of the Hejiakouzi in the Miaoshan fault fold belt, it is pointed out that the folds began to develop in the middle from the mid-late Pleistocene and gradually extended to the end. According to Cenozoic structural features, the genesis of the two fault zones in Miaoshan and Hongjianshan and their kinematic relationship with the Tianjingshan fault zone are analyzed.
