摘　　要：甘孜-理塘断裂带是“三江”地区东缘的重要成矿带。对该断裂带中部成矿-控矿特征进行了综合分析,结果表明金矿床（点）均位于断裂带内构造长期活动地区;区内断裂主要为压扭型韧性剪切和逆冲-平移型韧性剪切构造;甘孜-理塘断裂带构造复杂,次级断裂广泛分布,为矿液运移和储存提供了良好的通道和场所。通过对本区断裂带成矿-控矿的研究,为找矿勘探工作提供了有利的理论基础。Ganzi Litang fault zone is an important metallogenic belt of the eastern margin of Sanjiang region. The ore controlling characteristics of. central ore in the fault zone are analyzed, results show that the gold deposits （points） are located in the long-term activities in the region within the tectonic zone fault; fault zone is mainly transpressional ductile shear and thrust slip ductile shear structure; Ganzi Litang fault zone structure complex, secondary faults widely the distribution, provides a good channel and place for ore fluid migration and storage. Through the study of mineralization and ore control in the fault zone of this area, it provides a favorable theoretical basis for prospecting work.
