破劈理

破劈理的新类型&张劈理

A New Type of The Fracture Cleavage & Tensile Cleavage

第二期为平行造山带的挤压缩短变形，形成区域透入性共轭破劈理或膝折带。

The second episode is characterized by NW-SE direction compression-shortening deformation with formation of two conjugate fracture cleavages or kink bands .

第二幕为叠加在第一幕之上的北西向（310°&330°）紧闭相似或同斜褶皱及破劈理等，属准塑性状态下的变形；

The second is NW ( 310 ° & 330 °) closed similar or congruous folds and fracture cleavages superposing on the first formations under the state of quasi-plastic ;

通过野外现场观测，壁上绝大多数断层擦痕均呈东西走向，向东倾斜，倾角10-20°。还可以见到多组破劈理面，走向东西。

It is showed that most of the fault scratches on the walls from east to west , inclined to east , angle 10 ° - 20 ° by the field observations . It is developed multiple sets of cleavage break and NW trenching .
