| 摘 要： | 本文利用1：100万区域重力、构造航磁、大地电磁测深和地震测深等地球物理资料，研究了祁连造山带区域构造、深部构造和区域控矿作用；祁连山造山带与周边具有不同地球物理场特征是划分构造单元的依据，在内部基底断裂构造具有南北分带，东西分块的特征。深部构造处在地壳厚度变异带边缘。并要考虑构造演化对成矿控制的阶段性。

| Abstract: | On the basis of geophysical data of scale 1：1000 000 including regional gravity, airborne magnetic survey of structures, magnetotelluric sounding, seismic sounding, the regional structure, deep structures, and regional metallogeny of Qianlian Orogenic Belt are studied. It is supposed that the deferent geophysical field characteristics of Qilian Orogen Belt from the surrounding area should be the evidences to classify tectonic element, internal structures of basement is characterized by zoning from south to north and several massif from east to west, the deep fractures is in the edge of crustal variation belt, the ore-forming were controlled by the stages of structural evolution. |
