近年来,在找矿勘探和成矿预测的工作中,已经注意到基础理论研究的重大实际意义。大地构造与矿床学结合而成的新兴学门“成矿学”的研究,就是这方面的途径之一。目前,采用作为成矿学基础的大地构造理论多种,地洼学说(构造—岩浆活化理论)是其中之一。 (一) 五十年代以前关于地壳构造单元及地壳演化规律的看法自1859年美国学者J.Hall的地槽概念提出以来,关于地壳构造单元和发展规律问题的理论,最流行的为地槽—地台学说。该说认为大地构造单元有二,即地槽区和地台区。地槽区为一种强烈活动型的构造单
In recent years, in the prospecting and mineral prospecting work, we have noticed the significant practical significance of basic theoretical research. One of the approaches in this area is the study of the new study of geotectonics and ore depositology. At present, using diagenesis theory (tecto-magma activation theory) is one of the many theories of tectonics based on mineralization. (I) Opinions on the Evolution of Crustal Structural Units and the Crust Since the 1957s Since the concept of the geosyncline was proposed by American J.Hall in 1859, the most popular theory of crustal structural units and their developmental laws is that of the earth- Platform theory. The said that there are two tectonic units, namely the trough area and the platform area. Trough area is a strong activity of the single structure
