| 摘 要： | 该文讨论了以TM卫星影像解译为手段, 综合了地貌形态、水系展布特征以及新构造运动方面的信息, 提出了在被海内外学者称之为“中国地质百慕大”的松潘──甘孜造山带主体的东侧, 以四川西部的丹巴县为中心的地区存在着一个较为显着的旋涡状构造。并在研究前人资料的基础上、从地层分布和变质作用、褶曲形态和断裂构造特点等方面证实了该旋涡构造的存在, 对它的形成过程与发展进行了探讨。

| Abstract: | Abstract Songpan-Ganzi 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 paper makes an approach to its formation and evolutionary process. |
