摘要: 通过对内蒙古东南部中生代地质构造特征的综合研究,将该区域内中生代构造应力事件划分了8个阶段。构造应力场的压、张应力交替变化,此起彼伏,此消彼长,反映出地壳存在着弹性运动。地壳的发展历史就是在弹性运动过程中不断调整平衡,在调整平衡过程中形成了各种建造和构造。其动力主要来源于地球自转造成的地应力变化。

Abstract: On the basis of a synthetical study of geological structural features in Mesozoic Era in Shuangjing area,Kalaaqin area and Wolitu area,Inner Mongolia,regional tectonic stress events are divided into seven times.Compressive tectonic stress and tensile tectonic stress fields took place alternately,showing that in the Earth occurred elastic movement.The history of the Earth is the course that its elastic movement is situated in the state of continual accommodation and the balance.During the course a variety of formations and structures was formed.Their dynamics is the ground-stress change caused by the Earth rotation.
