如图-1所示的板块构造,本世纪初,德国人魏格纳认为是不同历史时期中各个大陆发生大规模水平运动而形成的。这就是“大陆漂移说”。这一学说,当时引起热烈地争论。结果被斥为“不现实的奇谈怪论”而搁置下来。第二次世界大战后,50年代的后半叶,由于古地磁学的研究,大陆漂移说东山再起。根据古地磁学所得到的美洲大陆相对的极移曲线和欧洲大陆相对的极移曲线,存在着系统地不一致。而这种不一致性也反映于重新按大陆漂移的设想绘制的图象上,就是清楚的证明。
As shown in the plate structure in Figure 1, at the beginning of this century, the German Wegner considered it to be a large-scale horizontal movement on all continents in different historical periods. This is “Mainland drift said ”. This theory was heatedly debated. The result was denounced as “unrealistic idiots” and set aside. After the Second World War, in the second half of the 1950s, due to paleomagnetic studies, the mainland drifted to the east. There are systematic inconsistencies based on the relative polar shift curves of the continental United States obtained from Paleomagnetism and the relative polar shift curves of continental Europe. This inconsistency is also clearly evidenced by the fact that it is also reflected in the image of a hypothetical re-continent drift.
