摘要

摘要: 在挤压推覆构造地区,推覆断层上盘的地层构造变形可用Suppe的断层弯曲褶皱几何要素来描述。在经典平衡剖面的假定前提下,笔者编制出一套以Suppe几何模型为基础的平衡剖面正演计算程序。在程序中,笔者不仅扩充了以往计算中对断面形态的简化处理,而且还辅以Williams的反演法获得初始断层参数。只要给出断层数目及其构造解释模型,即可求得给定区域内推覆构造的正演平衡剖面。笔者用该程序计算并绘制了川东地区大池干构造的平衡剖面以及大池干背斜的构造演化图。

Abstract: The hangingwall deformation of the overthrust under severe compression may be revealed by using Suppe's fault-bend folding approach.On the assumption of the classical computation of the forward balanced cross section,the program presented in this paper for computing the forward balanced cross section is based on Suppe's geometric model.This program is extended not only to simplify the processing of the computation on the geometric fault,but also assist the user in gaining the parameters of the initial fault by William's inverse method.The certain forward balanced cross sections can be simulated once the number of faults and their structural interpretation models are given.In this paper,the balanced cross sections of the Dachigan Anticlinal Structure in East Sichuan is computed and plotted by this program.
