地洼区(活化区)——大陆地壳第三构造单元这是关于地壳演化规律的一个科学新概念,由中国地质学家陈国达首先提出并与其它研究者共同完成,荣获1982年国家自然科学奖二等奖。从19世纪后期以来,地质学中最流行的大地构造理论是外国学者的地槽——地台学说。这个曾统治整个地球科学的理论认为地壳发展的形式仅有地槽和地台区两种基本构造单元,它的权威性影响了我国学者对大地构造性质的认识。陈国达从中国实际出发研究了中国东部大地构造,于1956年首先提出用活化区描述中国东南区大地构造性质,形成地洼学说,否定了传统地质学支柱——“槽台论”的观念。他分析了地壳相对稳定又重新强烈活动的事实,指出这是除地槽、地台之外的第
Diwaci (Activation Zone) - The Third Tectonic Unit of the Continental Crust This is a new scientific concept about the evolution of the crust. It was firstly proposed by Chinese geologist Chen Guoda and completed jointly with other researchers and won the 1982 National Natural Science Award second prize. Since the latter part of the 19th century, the most popular geotectonic theory in geology has been the theory of terraces and terraces of foreign scholars. This theory, once ruled over the entire earth science, holds that the crustal development forms only two basic tectonic units, namely, the Earth's trough and the platform area. Its authoritativeness has influenced our scholars' understanding of the nature of the earth's tectonics. Based on China's actual conditions, Chen Guoda studied the geotectonic structures in eastern China. In 1956, he first proposed that the tectonic properties of the southeastern area of China should be described by activation zones and the geology of geology should be formed. The concept of geotagging, the traditional theory of geology, should be negated. He analyzed the fact that the crust was relatively stable and re-active, noting that it was a
