七十年代期间,地球动力学的活动继续在检验和完善板块构造模式。这个模式在解释和预测有关大洋和大洋边缘的许多现象方面获得了明显的成功。而在大洋边缘所观察到的作用又提供了有关地球历史最近38亿年以来火山弧、山系,最后是陆壳的形成和演变的信息。然而,尽管板块构造学说获得了成功,但问题和矛盾仍然存在,其部分原因是其模式过于简化。国际岩石圈委员会关于重点研究岩石圈动力学及其演化的决定,就反映了对岩石圈及其下面的地幔物质的
During the 1970s, the activities of the geodynamics continue to examine and improve the plate tectonic model. This model has shown clear success in explaining and predicting many phenomena related to the margins of the oceans and the oceans. The observed effects at the margins of the ocean, in turn, provide information about the formation and evolution of volcanic arcs, mountain systems, and, finally, continental crustes since the last 3.8 billion years of Earth’s history. However, despite the success of plate tectonics, the problems and inconsistencies still exist, in part because of the simplistic pattern. The decision of the International Commission on Lithosphere to focus its study on lithospheric dynamics and its evolution reflects the role of the lithosphere and its mantle beneath
