从上一讲我们知道,地壳在漫长的地质时期经历了多次构造运动,随之产生许多复杂的、不同类型的构造体系。即使在同一地区也常常可以看到先后有几个不同构造体系发生。由于各次构造运动的应力作用方式不同,所造成的构造体系类型也不同,它们之间必然产生极其复杂的关系。各个构造体系除了按照自己一定的分布规律展布以外,还常常受已有构造体系的牵制,部分迁就、利用或者改造、破坏已有的构造形迹,甚至将早期构造体系的某些
From the previous statement, we know that the crust experienced many tectonic movements during the long geologic period, resulting in many complicated and different types of structural systems. Even in the same area can often see there have been several different structural systems. Due to the different modes of stress action in each tectonic movement, the types of tectonic systems caused by them are also different, and they are bound to have an extremely complicated relationship. In addition to being distributed according to certain distribution laws, each structural system is often restrained, partially relocated, utilized or rebuilt by existing structural systems, destroying existing structural features, and even replacing some of the early tectonic systems
