通过对横切太后庙断层的三条剖面的研究,发现断层构造岩存在着明显的水平分带。在研究了太后庙断层下盘各构造岩带的化学成分,矿物成分、变形和重结晶特征及岩组图后,认为目前出露在断层下盘的各构造岩带是在不同深度、不同温度、不同的应力条件下形成的,这是由于断层多次活动,断层下盘不断抬升的结果。基于断层构造岩是断层活动历史的记录者这一指导思想,可知太后庙断层经历了应力积累—早期活动—相对平静—晚期活动—休眠五个阶段。结合本区地质发展史,认为两次活动阶段分别为燕山运动晚期和喜山运动早期。两次活动使嵩山地块抬升达6000米。
Through the study of three sections that cross the section of the Taihoumiao fault, it is found that there is a clear horizontal zoning in the fault structure rocks. After studying the chemical composition, mineral composition, deformation and recrystallization features and lithologic maps of various tectonic rocks in the footwall of the Taihoumiao fault, it is considered that the tectonic rocks currently exposed in the footwall of the fault are deformed at different depths and temperatures , Formed under different stress conditions, which is due to the multi-activity of the fault, the result of the constant uplift of the under-fault. Based on the guiding principle that fault tectonism is the recorder of the fault activity history, we can see that the Taihoumiao fault experienced five stages of stress accumulation-early activity-relatively calm-late activity-dormancy. Combined with the history of geological development in this area, it is considered that the two active phases are late Yanshan movement and early Himalayan movement respectively. Two activities to lift the Songshan block up to 6,000 meters.
