摘要: 该文将有限变形理论应用到埕岛地区古生界构造变形研究中。在基本构造特征和构造演化历史分析的基础上,将变形过程人为分解,建立了位移函数,计算了该地区古生界底面各点变形过程中位移矢量在东西、南北和铅垂方向的分量,定量描述了地质构造的变形特征,并分析了位移分量与构造活动期的对应关系。

Abstract: This paper applies the theory of finite strain to the study of Paleozoic structures in Chengdao region.A displacement function is established by resolving the straining processes based on the analysis of the basic tectonic features and their evolution.The E-W,N-S and vertical components of the displacement vectors of points on the bottom surface of the Paleozoic are calculated so as to give a quantitative description of the deformations.The correlation between the displacement components and the periods of tectonic activities is analyzed.
