摘　　要：鸡叫沟金矿床位于南祁连构造带党河南山裂谷加里东期Au-Cu-Pb成矿带,通过近几年来勘查成果揭示,矿体呈似层状,多由北东南西向断裂构造控制;鸡叫沟岩体为一复式岩体,根据地质剖面岩石样品分析结果及前人硫同位素测试结果显示,金成矿流体及物质来源均与岩体中二长岩有关,且矿体赋存于岩体与围岩内外接触带及次级断裂构造中。The Jijiaogou gold deposit is located in the Caledonian metallogenic belt of Danghe South Mountain rift valley in the southern Qilian tectonic belt.The exploration in recent years revealed that the orebody is layered and mostly controlled by the north-southeast-west fault structure.According to the results of rock sample analysis and previous sulfur isotope tests,the metallogenic fluid and material source are related to the monzonite in the rock mass,and the orebody exists in the contact zone and secondary fault structure between the rock mass and the surrounding rock.
