前面我们讲了地质力学野外工作方法的基础——构造形迹(结构面)的力学性质鉴定和辨别构造形迹的序次和转化。下面接着介绍确定构造体系的存在和它们的范围,以及划分巨型构造带和鉴定构造型式。 (一)构造体系的概念毛主席教导我们:“一切客观事物本来是互相联系的和具有内部规律的”。地质构造现象也不例外。地质力学工作,在长期实践中,逐渐认识到组成地壳的各种岩层、岩体(包括各种形态的矿体)中的每项构造形迹,都有和它相伴而生的一群构造形迹,它们互相联系,其分布是有规律可寻的。因此,研究地质构造,不能孤立地看单个构造现象,而应从构造形迹的相互关系及其发生发展上去研究分析问题,从总体上去探讨一个地区地质构造的内在联系和固有的规律性。每一群构造形迹和其它有成生联系的构造形迹,往往各别形成构造带。构造带之间,有时存在着构造形迹不甚显著的地块,和围绕 Earlier we talked about the foundation of field work methods for geomechanics - the identification of the mechanical properties of structural (structural) surfaces and the identification of the order and transformation of structural features. The following is followed to determine the existence of structural systems and their extent, as well as the division of giant tectonic belts and identification of structural patterns. (A) the concept of structural system Chairman Mao taught us: “All objective things are inherently inter-related and have an internal law.” The phenomenon of geological structure is no exception. In the long-term practice of geomechanical work, it is gradually realized that every structural formation in various rock formations and rock masses (including various forms of ore bodies) has a group of structural features accompanying it Interlinked, its distribution is regularly found. Therefore, the study of geological structure, we can not look at a single structural phenomenon in isolation, but from the relationship between the structure of the trace and its occurrence and development to study and analyze the issue, to explore the overall geological structure of a region’s internal relations and inherent regularity. Each group of structural features and other structural relationships that are closely related to each other often form structural zones separately. Between the tectonic belts, there are sometimes massifs that are less pronounced in structure and surround
