| 摘 要： | 板块构造学说解释了全球构造的许多现象，但尚未满意地解释大陆构造中的一些问题，例如陆内造山带的形成、造山带和盆地形成的复杂历史和旋回性问题、大陆构造圈的不均一性等。新近提出的一些构造模式，都不约而同地指出了软流圈在大陆构造发展中的重要作用，但尚未成功解决软流圈运动的驱动力问题。本文认为，大陆岩石圈与软流圈之间相互作用关系的深入研究，是阐明大陆动力学过程的关键之一。此外，本文还对“软流体振荡作用”工作假说作了初步讨论。

COUPLING BETWEEN CONTINENTAL LITHOSPHERE AND ASTHENOSPHERE:A BREAKTHROUGH POINT IN CONTINENTAL DYNAMICAL STUDY |
| |
| Abstract: | In spite of great popularity of plate tectonics and its successful application in explain-ing some global tectonic phenomena,the concept contains certain shortcomings and contradic-tions. Many continental tectonic problems,such as formation of intracontinental mountains,complex history and cyclicity of orogenic zone and basin development , and inhomogeneity ofcontinental tectonosphere,cannot satisfactorily solved in terms of this concept.In terms of sometectonic hypotheses proposed in recent years have been raised the importance of asthenosphereor asthenoliths in the tectonic activity as if by previous agreement,but with these hypothesescannot successfully solved the driving force problem of asthenolith movement. The present pa-per suggests that a profound study of the interacting relationship between continental litho-sphere and asthenosphere is one of the keys to understanding continental dynamics. In this pa-per,a new working hypothesis,“asthenolith vibration”concept is discussed. |
