| 摘 要： | 内蒙古额济纳旗老硐沟矿床为氧化淋滤型金矿床。金矿脉严格受白云石大理岩中近ＥＷ和ＮＷ向断裂破碎带控制，在激电等物探方法找矿难以奏效的情况下，采用甚低频电磁法（ＶＬＦ）能准确地圈定覆盖区与金矿化密切相关的断裂破碎带。该方法简单轻便、高效，紧密结合金矿控矿因素和化探异常，找金效果明显。

| Abstract: | The Laodonggou gold deposit in the Erjinaqi,Inner Mongolia is an oxidizing-Leaching type gold deposit.The veins were mainly controlled by near EW- and NW-trend fracture zones in the dolomite-marble.The fracture zones related closely to gold metallization in cover field can be precisely delineated by VLF-EM method.Combined with studies of gold metallogenetic factors and geochemical anomalies,the VLF-EM would be seccessfully applied to determine ore-bearing fractures of similar ore deposit. |
