侵入岩是地壳的一个组成部分,也是地质力学研究工作的一个重要方面。根据笔者野外观察,对侵入岩之原生构造和岩相分带与构造体系的关系,试作初步探讨。一、关于侵入岩体的原生构造侵入岩体的“原生构造”常常被看作一个单独的构造单元。我们知道,岩体的形成在时间上和空间上都与区域构造运动有密切的关系,是否“原生构造”与区域构造运动也有
Invasive rock is an integral part of the crust, but also an important aspect of geomechanical research. According to the author’s field observation, preliminary discussion is made on the relationship between the primary structure of intrusive rocks and lithofacies zoning and structural system. First, the “native structure” of the intrusive rock intruding into the intrusive rock mass is often regarded as a separate tectonic unit. We know that the formation of rock mass is closely related to regional tectonic movement both in time and space, and whether the “native structure” and the regional tectonic movement also have
