板块构造学说,是从六十年代初期开始,由于海洋地质和海洋地球物理等科学不断的对大洋和大陆边缘进行了大规模的地质及地球物理的观察与考察,取得了一系列重要的研究成果,这些新发现的科学事实,不可避免的会促使新的大地构造理论的诞生。进入七十年代后,就初步建立成为一个内容丰富,并具有广阔前途的关于大洋壳和大陆壳发展过程的理论体系。 Plate tectonics theory is from the early 1960s, due to the marine geology and marine geophysics and other science on the ocean and the continental margin of large-scale geological and geophysical observation and investigation, made a series of important research results These newly discovered scientific facts will inevitably lead to the birth of a new theory of the tectonics. After entering the seventies, the theory system about the development of the oceanic crust and the continental crust has initially been established as an informative and promising future.
