通过邢北深部勘查区钻孔中所见的断层构造迹象分析,认为原来部分定为高角度的正断层是受太行山隆起赞皇变质核杂岩东侧拆离构造带影响而派生的中、小型低角度正断层。由于变质基底与上覆沉积盖层之间为软硬差距较大的主拆离构造面,在其影响下,上覆地层发育了若干个次级拆离构造面,邢北深部低角度正断层正是受基底拆离构造影响而形成。 According to the evidence of fault structure found in the deep exploration area of ​​northern Xingbei, it is considered that the normal fault, which was originally defined as a high angle, is derived from medium and small scale structural belts derived from the detachment tectonic belt to the east of the Zanhuang metamorphic core complex in the Taihang Mountains Low angle normal fault. Because of the main detachment structure between the metamorphic basement and the overlying caprock with large difference between hard and soft, several secondary detachment tectonic surfaces are developed in the overlying strata, It is formed by the substrate detachment structure.
