1956年,陈国达教授根据中国的中、新生代以来的地壳演化特点,首次提出后地台阶段“活化区”的概念,并指出这是一种不同于地台区和地槽区的大地构造第三基本构造单元——地洼区。五十年代后期,陈国达教授连续发表了一系列重要著作,阐述地洼区的特点、结构、及划分标准、与地槽区和地台区的区别,进而总结出地壳演化的动“定”转化递进律和地洼区成矿学,构成一个完整的理论体系,即地洼学说。地洼学说的创立,突破了近百年来
In 1956, according to the characteristics of the crustal evolution in China since the Mesozoic and Cenozoic, Professor Chen Guoda first proposed the concept of “activated zone” in the post-platform stage and pointed out that it is a geotectonic structure different from the terraced and terraced areas Three basic structural units - Di depression. In the late fifties, Professor Chen Guoda published a series of important works continuously, expounding the characteristics, structure and division standard of Diwa district, distinguishing from the terrane area and terraced area, and then summarizing the dynamic “definite” transformation of crustal evolution Progressive law and depression depression mineralization, constitute a complete theoretical system, that is, diwa theory. Diwa theory that the creation of breakthroughs in the past century
