摘要
以ＴＭ卫星相片解译为手段，综合地貌形态、水系展布特征以及新构造运动方面的信息，确定以甘孜州丹巴县为中心的区域内存在着一个旋涡状旋扭构造，并对它的形成过程与发展进行了探讨。
Songpan-Garze orogenic zone has long been known as 'Bermuda in Geology of China'.Interpretation of TM satellite image in association with information of the landforms,drainage distribution pattern and neotectonism reveals a whirl structure centering around Danba on the eastern side of this orogenic zone.This has been verified by the stratigraphic information,metamorphic trait,fold shape and fracture pattern.The present paper makes an approach to its formation and evolutionary process.
