摘要
本文从区域构造角度论述了剪切运动的普遍性和重要性,讨论了开、合、剪三种运动的辩证关系.剪切运动在区域构造演化中扮演着重要角色:转换断层协调大洋板块的扩张与俯冲;走滑断裂协调大陆盆地形成、造山带演化和地体运移;韧性剪切协调深部构造变形,并将地表构造和深部构造结合起来.开、合、剪处于同一运动系统中,其中开合是一对主要矛盾,剪切是桥梁与纽带;开、合往往导致突变与质变,剪切经常表现为渐变与量变.开、合、剪的辩证关系体现其运动的整体性、层次性、旋回性、互补性、共生性和互为因果等特征.
From the viewpoint of regional tectonics, this paper addresses the universality and importance of shear movement, which coordinates the whole process of the movement during the regional tectonic evolution.The dialectical logic of three movements including opening, closing and shearing are also discussed in the paper. Opening and closing is a pair of principal contradiction, shearing, however, is the bridge and linkage between them. The system of opening, closing and shearing movement is possessed of the characteristics of unity, cyclicity, complementarity, hierarchy association and interaction.
