太行山山前断裂带呈隐伏断裂展布于太行山脉与华北平原之间。该断裂带浅部由一系列北东至北北东方向的正断层斜列组成,控制了华北平原西部一系列隆起、断陷的形成;深部深切莫霍界面以下。太行山山前断裂带作为太行地块与平原地块的分界,其主体形成于早第三纪,晚第三纪至第四纪仍在强烈活动。结合近期形变与地震活动等资料,我们认为该断裂带南端的邯郸断裂是需要进一步加强监视的危险地段。
The Taihang Mountains piedmont fault zone was buried in the Taihang Mountains and North China Plain. The shallow part of the fault zone is composed of a series of normal fault oblique columns from the north east to the north east and northeast, controlling the formation of a series of uplift and fault depression in the western North China Plain. The deep part is deeply below the Moho interface. The Taihangshan piedmont fault zone, as the demarcation between the Taihang block and the plains, was formed in the early Tertiary and still active in the Late Triassic to Quaternary. Combined with recent deformation and seismic activity data, we think the Handan fault at the southern tip of the fault zone is a dangerous area that needs to be further strengthened for monitoring.
