原生构造 meaning in English

original structure
primary structure

The dislocation interfaces of early stage were controlled by the slide of the ne fold . the dominant dislocation interfaces , in the dam area , is the one of the second stage , which resulted from the slide of the lava layer and lagerkluftes from nw to se because of the affect of the majiaheba faultage ' s thrusting overriding to the dam area from nw to se . the dislocation interfaces of the third stage were the result of the overprint of the structure of ne to the one of nw
早期阶段形成的错动带受控于北东向纵弯褶皱的层间弯滑机制；第二阶段形成的错动带在坝区占主导地位，它们是由于北东向马家河坝断层由北西向南东的滑脱逆冲推覆影响坝区，并造成坝区向南东缓倾的岩层沿原生构造面向南东滑动的结果；第三阶段形成的错动带则是由于北西向构造叠加于早期北东向构造之上而致。
There are lots of primary structures , such as bed interfaces , lagerklufts and diagonal joints , in the emeishan volcanic , which dislocated to be dislocation interfaces later . especially in those primary structures that were filled with the epidote - quartz vein , the dislocation interfaces are more aptter to grew
错动带主要是利用玄武岩中原生层面、层节理和斜节理等原生构造错动变形而成，尤其是当原生构造中充填有热液型绿帘石?石英脉时，错动变形更易于发生。
