摘　　要：甘孜—理塘断裂带是重要的金铜多金属成矿带,沿断裂发育有晚三叠世曲嘎寺组中基性火山岩系及其有成因联系的铁质基性超基性浅成侵入体,构成典型的蛇绿岩建造,并为金的矿源层;金成矿主要在燕山-喜山期,与碰撞造山作用密切相关,形成了蛇绿岩(混杂岩)建造中的浅成低温热液型金矿;该带已发现嘎拉、错阿、生康、雄龙西、阿加隆洼等大中型金矿床,196处金异常,其中74个异常为Au,As,Sb,(Hg)组合异常,展现出巨大的资源潜力和找矿前景。Ganzi-Litang fault zone is an important Au, Cu polymetal ore belt in China. Late Trassic basic volcanic sequence of Qugasi formation and the genetically related Fe-basic rocks which are shallowly intruded composing typical ophiolite suit, the source bed of gold deposits. Au metallogeny is closely related to collisional orogenesis of Yanshan-Xishan epoch. The Au deposi zone gold deposits, such as Gala, Cuo＇ar, Shengkang, Xionglo and 196 Au anomalies delineated. 74 of the 196 Au anomalies ai thermal deposits. Along the fault alongwa etc. have been discovered erized by Au, As, Sb, （Hg） anomaly combination showing great potential for further exploration.
