主断层 meaning in English

dominant fault
main fault
major fault
master fault
master fracture
principal fault

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。
