摘　　要：研究区位于北羌塘陆块,晚三叠世早侏罗世陆缘褶皱带。在构造演化上,经历了海西—印支期主造山、燕山期伸展成盆、新生代板内成山、成盆及高原隆升三大演化阶段,筑就了区内不同时代、不同构造属性的各类地质体。The study area is located in the North Qiangtang land block and the late three fold early Jurassic continental margin fold belt. In tectonic evolution, experienced Hercynian Indosinian orogenic, Yanshan extensional basin and Cenozoic intraplate basins and mountains, plateau uplift three evolution stages, built all kinds of geological body in different times and different structural properties.
