本文涉及四川省大地构造的四重概念:大地构造单元、深大断裂体系、大地构造演化阶段和大地构造演化模式。一、大地构造单元大地构造单元的产生,是地幔与地壳、海洋与大陆、地台与地槽、稳定与活动等,循对立统一的辨证法则,在地质历史的长河中,相互制约、转化的最终结果。无论导致它们变化的原因是什么,也不论这种变化在时间和空间序列中多么错综复杂,不同地壳构造单
This paper deals with the quadruple concept of tectonics in Sichuan Province: tectonic units, deep-faulted systems, tectonic evolution and tectonic evolution. 1. Geotectonic units The tectonic units of the earth are the dialectical laws that follow the unity of opposites in the mantle and the crust, the oceans and continents, the terraces and terraces, stability and activity, etc. They are mutually restricted and transformed in the course of geological history Final Results. No matter what causes them to change, and no matter how intricately complicated this series of changes in time and space series,
