秦岭山脉（中国陕西）的结构涉及主要的东西向走滑断层。 1983年和1984年两次考察的现场观测表明，该断层是活动的，可能在始新世后发生了数十公里的左旋位移。断层急剧地切割了地貌并抵消了左侧的小河道。它们的痕迹以至少 50-100 m 宽的碎裂至糜棱岩非同轴变形带为标志。秦岭断裂使得华南地区向东挤压，可以被认为是阿尔金断裂系的最东延续。他们将中国东北部的伸展构造与喜马拉雅碰撞联系起来。
The structure of the Qinling Shan mountain range (Shaanxi, China) involves major east-south-east strike-slip faults. Field observations made during two expeditions in 1983 and 1984 show that the faults are active and may have undergone several tens of kilometres of post-Eocene left-lateral displacement. The faults cut the morphology sharply and offset left-laterally small channels. Their trace is marked by cataclastic to mylonitic non-coaxial deformation zones at least 50–100 m wide. The Qinling faults allow the eastward extrusion of south China and may be considered the easternmost continuation of the Altyn Tagh fault system. They link extensional tectonics in northeastern China to the Himalayan collision.
