浅谈大陆构造-板块构造的回顾与反思

60年代提出的板块构造理论拓宽了人们的思路,给地球科学带来了活力。但是随着对大陆区域地质调查的深入,发现大陆板块与大洋板块差异很大,用刚性板块运动学理论不能解释大陆内部复杂的构造形变和板内地震活动。J. Dewey(1986)和P. Molnar(1988)相继提出大陆构造及其研究方法。我国青藏高原是一个典型而独特的大陆构造单元,是最强烈的板内形变带和地震活动区,同时是亚洲大气环流的启博器。青藏高原很可能成为新的地球科学理论的诞生地。

PRELIMINARY STUDYING ON CONTINENTAL TECTONICS-REVIEW OF THE PLATE TECTONICS

It is obvious that the plate tectonics constitutes one of the great revolution in scientific understanding and that makes the geosciences powerful. Based on detailed investigations in the continental areas there are quite differences between oceanic plate and continental plate. It is difficult to apply the theory of rigid plate kinematics for explaining the continental deformations and intraplate earthquakes. Therefore, some distinguished geoscierrtists, such as J. F. Dewey (1986), P. Molnar (1988) have put forward continental tectonics and its methodology. In this paper, the author will briefly illustrate the development of the continental tectonics, then deal with the Qinghai-Xizang (Tibet) Plateau where is the most intensive intraplate deformation and seismic zone and would be the homeland in forming the new theory of geoscience.
