剪节 meaning in English
shear
Examples
- The fracture system was mainly made up of vertical fractures which were developed in different phases and showing themselves by plane x - conjugate joint systems . the current fracture character is the result of the himalayan movement
裂缝系统以发育垂直裂缝为主，可形成于不同时期，常成对出现共同组成平n中文摘要面x型共扼剪节理，现今的裂缝性质是喜山期最终作用的结果。 - Three stages of deformation can be distinguished from the cataclastic superposition of matrices that infilled the microcracks in cataclastic rocks , and two phas es of paleotectonic stress field from the typical conjugated shear joints by stereograms illustrating
构造岩中胶结物和微裂隙充填脉反映了岩石碎裂变形的三次叠加。断裂变形带内发育两期典型的共轭剪节理，但区域分布各有特点，反映出断裂变形的空间演化。 - The fault controlled the magmatism and metallization relevant to the contact zone , and deformed successively and produced cataclastic rocks and two sets of joints ; the second stage was from late cretaceous to eocene . the fault zone deformed right - laterally under ne - sw striking transtention , and new joints zone was produced at the end of the two main faults because of local stress concentration . the fault produced inchoative cataclastic rocks , and two sets of typical joints in plutons ; the third stage of deformation was relatively faint and only a little of microcracks was produced and infilled with vei ns in the deformed rocks , which was during the himalayan movement
其后的继承性活动在断裂带内形成碎裂程度最强达到碎裂岩的碎裂岩系列构造岩，变形带两侧发育两组典型的共轭剪节理；第二次在晚白垩世?始新世，断裂在北东?南西向近水平挤压作用下右行张扭性活动，断裂带两主断裂在斜列重叠的端部由于局部应力集中进一步扩展形成节理带，而断裂在岩体区也发育两组典型的共轭剪节理，断裂内形成初碎裂岩为主的构造岩；第三次是喜山期以西侧抬升、东侧下降的强烈升降为主的活动，在基岩中，主断层两侧围岩出现微破裂。 - 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。
