shear fault

This paper used two approaches such as quartz C-axis fabrics and strain ratios, oblique grain shapes and quartz C-axis fabrics to measure kinematic vorticity numbers of the late ductile shear zone in southern segment of the Tancheng& Lujiang ( Tan-Lu) fault zone.

本次研究中利用石英C轴组构与主应变比值的方法以及石英C轴组构与斜列颗粒形态的方法，测量了郯庐断裂带南段晚期韧性剪切带的运动学涡度。

The structural deformation of fault zone is mainly characterized by compressor-shear structure or shearing compressive structure.

断裂带构造变形以扭压或压扭构造为主要特征.

The mylonite and ultramylonite in the ductile shear zones yield whole-rock 40Ar/ 39Ar ages of 120. 48 Ma and 118. 75 Ma respectively, which suggest that large-scale sinistral displacement in the Tan-Lu fault zone took place in the Early Cretaceous.

肥东韧性剪切带中糜棱岩、超糜棱岩测得的~（40）Ar/~（39）Ar全岩年龄分别为120.48Ma和118.75Ma，说明郯庐断裂带的大规模左行平移时代为早白垩世。

Among them, fault No I in the central Tarim is regional synsedimentary fault and a pressure thrust fault shear.

其中，塔中I号断裂是一条活动时间长的区域性同沉积大断裂，也是一条压扭性逆冲断层。

The equilibrium equation of surrounding rock mining fault system is established. The fault destablizing process with shear failure pattern belongs to fold catastrophe model.
