“板块构造”是讨论地壳构造特征、运动规律和运动成因机制等问题的新学说。它是最近几年由原大陆漂移说和海底扩张说发展而来的。这个学说的创立引起了中外地质学家的很大注意,很多地质学家被它吸引过来,很快形成了一个研究和讨论板块的热潮。板块构造动摇着传统的大地构造学说,影响着地球发展史中的一些基本概念。因此,这门新学说必然激起地质科学领域里的新的纷争。总之,板块构造学说将对地质学 “Plate tectonics” is a new theory to discuss the features of crustal structure, laws of motion and mechanism of movement. It has evolved in recent years from the original mainland drift and undersea expansion. The establishment of this doctrine aroused great attention of Chinese and foreign geologists, many geologists were attracted to it, and soon formed a research and discussion section of the boom. Plate tectonics have shaken the traditional theory of tectonics and influenced some basic concepts in the history of the earth. Therefore, this new theory inevitably arouses new disputes in the field of geosciences. In short, plate tectonics theory will be geology
