GENERAL CHARACTERISTICS OF THE MESOZOIC-CENOZOIC TECTONICS IN EASTERN CHINA
-
摘要:
把中国东部中、新生界划分为6个构造-沉积旋回, 相应地发育6期构造运动主幕, 侏罗纪末幕运动是一场变格运动。进一步将研究区构造形变史划分为两个形变阶段和一个过渡阶段。两个构造形变阶段发育两种类型的沉积盆地、两种型式的构造体系, 它们之间存在着广泛的构造不整合, 显示二元结构即为中国东部中、新生代大地构造的基本特征。
Abstract:In this paper, the author divided the Mesozoic-Cenozoic in eastern China into six tectonic-sedimentary cycles.The movement occurred in the Late Jurassic was a style-changed movement.In addition, the author further divided the tectonic deformation history of this region into two deformation phases (T-J) and one transitional phase (K1).During the two deformation phases, two types of basins and two tectonic systems developed.There exists extensive tectonic unconformity, which shows that the duel structures are basic characteristics of Mesozoic-Cenozoic geotectonics in eastern China.
