摘要:
为了解决山西五台县代银掌矿区周边及深部找矿问题,在矿区选取6号、8号和12号3条勘探线剖面开展了地电化学方法试验研究,对通电(偶极地电提取)和不通电(泡塑吸附提取)条件下的地电化学方法试验进行了对比分析,验证了该方法在代银掌金多金属矿区找矿中的可行性以及外加电场对勘探效果的影响。研究结果表明:地电化学提取异常在已知金矿体上方显示清晰,与金矿体的赋存位置对应良好,勘探效果显著,说明在山西五台地区运用地电化学方法寻找隐伏金矿床是有效可行的。外加电场确实提高了地电化学提取效率,探测深度也大于不通电下的吸附提取,更加灵敏,对隐伏矿体和弱矿化异常都能有明显显示,异常与深部矿体的赋存位置对应度较高,提取到的矿体信息更加全面完整,对进一步分析地下矿体位置和展布形态有很好的效果,在深部找矿预测中可起到较好的指示效应。
