摘　　要：科迪巴依金矿位于新疆维吾尔自治区托里县的东部,地处西准噶尔地区哈图金矿成矿带的西段。该矿床地质勘查圈出了4条金矿化蚀变带(编号Ⅰ—Ⅳ),金矿赋存于褐铁矿化碎裂化凝灰质粉砂岩中。Ⅱ2、Ⅲ1为主矿体,长度360~750 m,厚度1.0~3.4 m,金品位w(Au)=0.46×10^(-6)~6.51×10^(-6)。矿床成矿地质条件和找矿标志显示,科迪巴依金矿床的形成主要受地层岩性、断裂构造和岩浆岩分布等因素的控制,属于接触交代型金矿床。结合矿区地球化学和地球物理特征,建立了地质地球物理地球化学找矿模式。Kedibayi Au deposit is located the eastern part of Tori county and in the Western section of Hatu Au mineralization belt in West Junggar area.Four alteration-mineralization zones(No.I-IV)have been delineated.Ore bodies II-2 and III1are main the ones with Au grade,0.46×10^(-6)~6.51×10^(-6),360-750 m long and 1.0-3.4 m thick occurring in limonitized cataclastic tuffaceous siltstone.They are mainly controlled by lithologies,fault and distribution of magmatic rock belonging to contact metastatic Au ore.Based on geological,geophysical and geochemical data available now is built the prospecting model of the Au deposit.
