一、巨型纬向构造体系巨型纬向构造体系(以下简称纬向带)与地壳运动之联系,是地质力学一项基本理论问题。李四光教授早年探讨地壳运动规律时即得到启发,经过几十年的研究,逐步深入,得出了一些基本的规律,充实了地质力学的基本理论。本文拟从地质力学的基本观点出发,根据地球表面客观存在的纬向构造形变,结合其他学科观测研究的成果,对巨型纬向带,作一些补充讨论。(一)巨型纬向带发生的原因及其展布的规律性1.纬向带发生的原因
First, the giant latitudinal tectonic system Giant latitudinal tectonic system (hereinafter referred to as zonal belt) and the crustal movement of the relationship between the geomechanics is a basic theoretical issue. When Professor Li Siguang explored the law of crustal movement in his early years, he was inspired by decades of research and gradually got some basic laws and enriched the basic theory of geomechanics. Based on the geomechanics basic point of view, according to the objective existence of the zonal structural deformation on the Earth’s surface and the results of observational studies in other disciplines, some supplementary discussions are made on the mega zonal belt. (A) the reasons for the occurrence of giant zonal belt and the regularity of its distribution 1. zonal belt causes
