一、构造序次的基本概念在第二讲里,我们介绍了构造形迹的力学分类、各种结构面力学性质的鉴定及其组合关系,这是认识地质构造现象的基础工作,对于构造形迹之间的内部联系及其发生发展的规律,还需要进一步探讨。毛主席教导我们:“不但要研究每一个大系统的物质运动形式的特殊的矛盾性及其所规定的本质,而且要研究每一个物质运动形式在其发展长途中的每一个过程的特殊的矛盾及其本质”。在探讨结构面的力学本质及其相互联结时,我们了解到同一岩块或地块在同一方式动力作用期间所产生的各项构造形迹,是一连串 First, the basic concepts of structure order In the second lecture, we introduced the mechanical classification of structural features, the mechanical properties of various structural planes and their combination of identification, which is to understand the geological structure of the basic work of the phenomenon of structural features Between the internal relations and the occurrence and development of the law, but also need to be further explored. Chairman Mao taught us: “It is not only necessary to study the special contradictions and the stipulated essence of the material movement form of each large system, but also to study the special contradictions in every process of every material movement form in its long-distance development And its essence. ” When discussing the mechanics essence of the structural plane and its interconnection, we know that all the structural features of the same block or land during the same mode of dynamic action are a series of
