摘　　要：多拉纳萨依金矿位于新疆北部额尔齐斯成矿带西端,是一构造蚀变岩型金矿。金矿矿体受构造控制明显,该矿控矿、成矿构造规模大,控制长度大于10km。矿区矿化蚀变发育,以硅化、黄铁矿化、绢云母化为主。EH4连续电导率剖面测量表明,矿化向深部延深大于380m,异常宽度50m,指示了该矿床具有良好的成矿前景,该金矿区是一大型金矿找矿靶区。Duolanasayi gold deposit locates at the western Eerqisi metallogenetic belt in north Xinjiang, it is a structural altered rock type gold deposit. The gold ore bodies are controlled by the interlayer slip faults. The length of the controlling ore structures is larger than 10km. The ore types are mainly structural altered rock type. The main alterations are silification, sericitization and pyritization. The results of EH4 Electrical Conductivity Imaging system measurement show that there is a clear geophysical anomaly in depth of the Duolanasayi deposit,the anomaly exceeds 380m in depth and 50m in width. It indicates that the gold deposit has a good metallogenic foreground and is a big type exploration target of the gold deposit.
