由于地壳在不同方向上发生变化,并且是不可逆的,因此它的主要特征之一就表现为物质组成和构造的不均一性。当编制各种用途的构造图时,构造区划即区分出不同级别的自然物质构造体。构造体的形成是各种地质构造作用在空间和时间上表现的结果,而这一作用的总活动则取决于所谓的构造状态。构造区划及弄清构造状态的类型是了解地壳构造发育史的主要方法之一。
As the crust changes in different directions and is irreversible, one of its main features is the heterogeneity of its composition and structure. When compiling construction drawings for various uses, structural divisions distinguish between different levels of natural material structures. The formation of structures is the result of the spatial and temporal performance of various geological formations. The total activity of this role depends on the so-called tectonic state. Structure zoning and clarify the type of tectonic state is one of the main methods to understand the history of crustal structure development.
