  • 摘要: 采用音频大地电磁测深(EH4)对东炉房铜钼多金属矿区深部地质构造进行探测分析,有效确定了矿区地下的空间电性和结构特征。通过构建音频大地电磁法(EH4)找矿标志,总结了EH4剖面视电阻率异常特征与矿体关系:浅部呈脉状或柱状低阻体对应中低温热液型金、铅、锌多金属矿体,呈柱状中阻体或中低阻体对应矽卡岩型或斑岩型铜钼多金属矿体,中阻体对应中酸性岩浆岩(玢岩、斑岩)。圈定了矿区深部隐伏矿体11处,其中5处与钻孔吻合,其余6处找矿前景良好;进一步推断在深部岩体中形成规模较大的斑岩型铜钼矿。研究表明音频大地电磁测深法针对东炉房铜钼多金属矿或者该类型矿床寻找隐伏岩(矿)体是有效的地球物理方法。
