摘要
基于"构造体系控油作用研究"项目,总结中国东部中新生代大地构造的基本特征及其演变的内在规律。研究表明,中国东部中新生代构造形变史,以侏罗纪末幕运动为标志划分为前后2个大阶段,发育2种巨型扭动构造型式,即华夏系和新华夏系,其间存在广泛的构造不整合;显示二元结构,即新华夏系形变构造层与华夏系形变构造层的叠置,是本区大地构造的基本特征。
Based on the theory of geomechanics, the Meso-cenozoic tectonic characteristics and evolution in eastern China were concluded. This research shows that the history of the Meso-cenozoic deformation is divided into two stages in eastern China and the demarcation is the movement in Late Jurassic. There are two different structural patterns, Cathaysian and Neocathaysian, and there exists the tectonic unconformity between the two stages. The main tectonic characteristics is the overriding of the deformation structure layers in dual-structure, Cathaysian and Neocathaysian in this area.
