一、引言前人对本区震旦系的研究多侧重地层的划分和对比,而对其构造则重视不够。作者等虽多年来着重研究本区的构造形变史,但对震旦系构造特征的认识,长期以来只看到一些表面现象,而对其本质的认识则经历了一个不断反复和深化的过程。首先是震旦系和寒武系的接触关系,在豫西、华北乃至中国东部,它们之间都主要是假整合的平行接触关系,也就是在震旦纪末波状运动基础上,寒武纪海浸超覆。而唯独在
I. INTRODUCTION The predecessors’ research on the Sinian in this area mainly focused on the stratigraphic division and comparison, but paid little attention to its structure. Although the authors have focused on the tectonic deformation history of the area for many years, their understanding of the structural features of the Sinian has long seen only some superficial phenomena. However, their understanding of their essence has undergone a process of continuous repetition and deepening. The first is the contact between the Sinian and Cambrian systems. In western Henan, northern China and even in eastern China, they are all mainly pseudo-integrated parallel contact relationships, that is, on the basis of the Sinian wavy movement, the Cambrian sea- cover. And only in
