本文试图运用各主要大地构造学派的理论观点,地质历史分析与地质力学分析相结合的方法,具体剖析松潘一甘孜褶皱系的构造演化特征。本文所称松潘—甘孜褶皱系的范围,限定于东起后龙门山—锦屏山深断裂,西止邓柯—甘孜—理塘—博窝深断裂,北界东昆仑—西秦岭南缘深断裂,广覆着巨厚的上三迭统西康群复理石建造的三角区域内。黄汲清先生等所称玉树—义敦褶皱带,本文将之划归三江褶皱系
This paper tries to analyze the tectonic evolution characteristics of the Songpan-Ganzi fold system by using the theories of major tectonic schools, the methods of geological history analysis and geomechanics analysis. The scope of the Songpan-Ganzi fold system in this paper is limited to the Longmenshan-Jinping deep-seething fault in the east, the Dangke-Garze-Litang-Bodo deep fault in the west, the deep fault in the east Kunlun-West Qinling margin of the north boundary , Widely covered with huge thick Triassic Xikang group flysch built triangular region. Mr. Huang Jiqing and other so-called Yushu - Yidun fold belt, this article will be placed under the Sanjiang fold system
