tectonic rock meaning in English

构造岩

Zijingguan fault zone is characterized with cataclasite series of tectonic rocks and joints alongside the deformational zone , and sometimes with uniclinal flexure or folds . the intensity of deformation increases from the sides to the center of the fault in the section , which appears from joints to cataclastic rocks
紫荆关断裂带两主断裂变形带以碎裂岩系列构造岩和节理带组合为特征，局部出现挠曲和褶皱，由两盘至断裂中心变形强度增大，一般由节理带过渡为碎裂岩带。
Detailed structural information and specimens of tectonic rock had been collected in the outcrop sections along the fault zone , and deformation feature and superposition about the tectonic rocks were analyzed , and paleotectonic stress field was also analyzed by stereograms illustrating of joints in the following work
在室内对构造岩进行了变形特征和变形叠加分析，对断裂带典型共轭剪节理作主应力轴图解分析了古构造应力场。进而探讨了紫荆关断裂带的构造活动特征。
