摘要
多期构造叠加使变质岩区的结构构造面貌变得十分复杂,难以研究。因此,正确地识别叠加褶皱,就成为查明变质岩区构造及变形历史的关键之一,也是建立变质岩层层序最需重视的问题。本文提出了一种基于小波变换的纹理分析,从TM图像上提取叠加褶皱信息的图像处理方法,通过对南天山东段铜花山—硫磺山地区的多次反复实践和验证,取得了野外难以获取的良好效果。
Structures in metamorphic terrains are very complex and very diff icult to study because of polyphase superimposition.So to recognize superposed folds correctly is one of the keys to identify the structures and deformation history in metamorphic terrains.This paper proposes a method of processing ima ges by extracting the practice and checks of this method in the Tonghuashan-Li uhuangshan area in the eastern segment of the South Tianshan Mountains ,good results have been achieved.
