论全球海陆变迁的主要原因

历史发展过程中不少专家学者,对地球上各个大陆形成演化作了多年大量的研究工作,但认识千差万别。如最早的大陆漂移学说,后来又出现海底扩张学说—板块构造学说等等。经过多年研究认为,全球7个大陆不会漂移,而且也无充分依据将地球划分成几个板块。因为板块构造学说的运动机制基本是合理的,但是,板块划分依据不足、各板块的界线不明确、各板块的地质差别及特征不清楚等。所以,笔者认为全球各大陆整体是不分的,各个陆块地质时期的变化,是海陆变迁的结果。

The main causes of global land and sea changes

In the process of historical development, many researchers have done a lot of research work on the formation and evolution of each continent on the earth, but their opinions are quite different from each other. The earliest theory was continental drift, and later, there appeared the theory of sea floor expansion and plate tectonics. Based on years of research, the author believes that the six continents of the world do not drift, and it is impossible to divide the earth into several plates on a sufficient basis, because the dynamic mechanism of plate tectonics is basically reasonable. However, the basis of plate division is not enough, the boundary of each plate is not clear, and the geological differences and characteristics of each plate are not clear. Therefore, the author thinks that the whole continent of the world is inseparable, and the change of the geological period of each landmass is the result of the change of sea and land.
