岷江上游地区位于四川盆地西部边缘的秦岭纬向构造带、龙门山北东向构造带(华夏系)与马尔康北西向构造带间的三角形地块内.在漫长的地质历史发展过程中,在相应的构造地域内发育了各自不同特色的岩相建造,历经晋宁——澄江运动、印支运动、喜山运动等多次构造变动,形成了不同特征的构造型式,包括秦岭纬向构造、较场山字型构造、知木林山字型构造、热务沟旋卷构造、薛城“S”形构造、石大关弧形构造、龙门山华夏构造、马尔康北西向构造及青城——青霞新华夏构造.在他们毗邻的范围内,发生相互干扰、穿插或结持,形成各种构造的复合现象.同时伴以岩浆活动与变质作用,使之更加复杂化,造成了目前错综复杂而又井然有序的构造图景.
The upper reaches of the Minjiang River are located in the Qinling westerly structural belt on the western margin of the Sichuan Basin and within the triangular block between the northeastern structural belt of the Longmen Mountains (Cathaysianian) and the Malcolm north-west structural belt.In the course of long geological history, In the tectonic region, different lithofacies have been developed. After many structural changes such as the Jinning-Chengjiang, Indo-China and Himalayan movements, structural features of different features have been formed, including the Qinling zonal structure, Mountain font type structure, Zhumu mountain type structure, Jindou spiral volume structure, Xuecheng “S” shape structure, Shidaoguan arc structure, Longmenshan Huaxia structure, Malcolm NW structure and Qingcheng - Qingxia The Neo-Huaxia tectonics, where they are adjacent to each other, undergo mutual interference, interspersed or knotted to form complex phenomena of various tectonics, complicated by magmatic activity and metamorphism, resulting in the current complicated and well-formed Ordered structure of the picture.
