一、深大断裂的提出与特点及其重要意义: 对地球深部的地质作用与表层地质作用之间关系的研究,无论在理论上和实践上均有重大的意义。(譬如:在解释许多矿物在地壳表层中质的聚集,特别是矿物量的聚集时,必须认识到地球深部才真正是大量物质聚集的场所。在这一点上已牵涉到岩浆活动及构造运动了。)在苏联许多学者很早就强调指出深部构造,尤其是深大断裂在地壳的构成和发展上的
First, the proposed and characteristics of the deep fault and its significance: The deep study of the relationship between the geological function of the Earth and the surface geological, both in theory and practice are of great significance. (For example, in explaining the mass accumulation of many minerals in the crustal surface, especially in the accumulation of minerals, it must be recognized that deep in the earth is indeed the place where a large amount of matter is concentrated, and magmatic activity and tectonic movement have been involved .) Many scholars in the Soviet Union have long emphasized the importance of deep tectonics, especially the deep faults in the formation and development of the crust
