太行山屹立在华北平原西侧,气势磅礴,巍然突兀。在地质构造上,适位于中朝陆台中枢地区,历来为地质工作者所重视,因而论述颇多。有人认为太行山是以褶皱运动为特征,为燕山运动的产物;有人认为太行山系发生于燕山运动末期的断裂束,属山西隆起的次一级构造单元。其构造特征基本上和北京西山相同,表现为开阔背斜或向 Taihang Mountain standing on the west side of the North China Plain, magnificent, towering towering. Geological structure, suitable for the Central and South Taiwan Rift Valley Center, has always been valued by geological workers, and thus discussed a lot. Some people think that the Taihang Mountains is characterized by fold movement, which is the product of the Yanshan movement. Some people think that the Taihang Mountains occurred in the late Yanshanian movement of fault bundles, which belong to the sub-primary tectonic units of Shanxi uplift. Its structural features are basically the same as that of Beijing Xishan, showing an open anticline or direction
