滹沱河上游，代县太和岭口村附近发现新构造断裂群，主干断裂发育在基岩山体与第四系之间，断面倾角较缓且略呈上陡下缓趋势。正断层的下降盘出现反向牵引的背斜和反向正断层。它寓示着断层的水平位移量与速率可能高于垂向的位移量与速率。因而具裂谷拉张过程中形成的铲状低角度正断层的特点。
A new tectonic fault zone is found near the upper Hutuo River and Taihelingkou Village, Dai County. The main fault develops between the bedrock and Quaternary. The dip angle of the section is gentle and slightly steeply downward. The negative plate of the normal fault shows reverse-dragged anticlines and reverse normal faults. It shows that the horizontal displacement and velocity of faults may be higher than the vertical displacement and velocity. Therefore, it has the characteristics of shovel-shaped low-angle normal fault formed during rifting.
