摘　　要：甘孜—理塘断裂带是一发育在同名洋脊型火山岩—蛇绿岩带之上以金为主的成矿带,金矿化围岩以晚二叠—晚三叠世的火山—沉积岩系为主。阿加隆洼金矿床为产于成矿带中段的中型金矿床,矿床严格受断裂带控制,其容矿岩石主要为变碎屑岩和构造角砾岩,经综合分析,得出该矿床为构造蚀变岩型金矿床。Garze-Litang fault belt is an important gold metallogenic belt, which develops on the same name ocean ridge volcanic-ophiolite zone. The mineralization wall rock is mainly volcanic-sedimentary rock series in late Permianlate Triassic. Ajialongwa gold deposit lies in the middle section of the metallogenic belt, controlled by fault zone. The host rock is meta-clastic rock and breccia. According to comprehensive research, we conclude that the Ajialongwa deposit is structural-altered rock gold deposit.
