不同大地构造发展阶段及构造区之间的过渡性现象

分析地壳动定递进演化发展过程,研究了不同大地构造发展阶段及不同构造区之间的过渡性现象.认为在时间演化上,当一种大地构造阶段被另一种大地构造阶段替代时,存在着过渡期,在空间分布上,不同的大地构造区之间存在着过渡带.这种过渡期和过波带统称为过渡性现象,其实质代表了不同地质时代以及同一地质时代不同空间地壳动定递进演化过程中由量变到质变的过程.

TRANSITIONAL PHENOMENA AMONG THE GEOTECTONIC STAGES AND GEOTECTONIC REGION

In this paper,the transitional phenomena among the geotectonic stages and geotectonic region was discussed on the basis of analysing the progressive evolution process of the crust between mobile and stable regions. It is considered that there must be transitional stage when one geotectonic stage is substituted by another in time evolution process and transitional belts from one geotectonic region to another in spatial distribution. These transitional stages and belts are called transitional phenomena which,in fact,represent the process from the quantitative to qualitative changes in the progressive evolution between mobile to stable regions in different geological times or in different space at the same geological time.
