摘    要:板内变形是当今板块构造研究的前沿,本文着重讨论了研究板内变形的一种可能途径。其思路如下:首先,从地球动力学出发,充分考虑周围板块的构造背景,然后将板块作为一个整体,全面、系统地研究板內各块体的特殊性及不均一性.在此基础上,将板缘作用对板內各板块产生的影响和板内地球的深部作用及软硬不同的块体之间的相互作用结合起来,综合分析不同时代、不同应力布局、不同变形方式和强度的板內各块体的內在联系,探讨板內不同块体可能的变形机制.

关 键 词:板块构造 板内变形 板缘作用

Abstract:The problem of intraplate deformations has been considered to have an important position in recent researches of the plate tectonics, This paper mainly discusses a possible way to research intraplate deformations. The way of thought is as follows: first and foremost, starting from geodynamics, the tectonic setting of the peripheral plates is carefully thought out; Then, the heterogeneity and particularity of all tectonic blocks in a plate as a whole are studied comprehensively and systematically; On the basis of the above-mentioned, combining influences on all tectonic blocks of intraplate resulted from actions of plate boundary, earth deep-seated action of intraplate with interaction of tectonic blocks of rigid differences, internal relations of all blocks involving different era, different distributions of stress, differences of deformation style and intensity are analysed syntheticaly; Finally, possible deformation mechenics of all tectonic blocks in a plate are sought.
Keywords:Intraplate deformation  Tectonic blocks  Action of plate boundary
