摘要
地电化学提取法是在动态平衡的原理上,利用人工电场提取深部的矿化或成矿离子进行成矿预测,确定成矿靶区。通过在五圩花洞锌矿区开展的地电化学异常提取的综合分析,在隐伏矿体上方出现明显的Zn、Pb、Sb、Ag异常,异常出现的位置与已知矿化体出现的地质位置比较吻合,表明该方法对深部矿体预测具有较强的指示意义。根据异常特征,圈定了5处有利的找矿靶区。
The geo-electrochemical extraction method is based on the principle of dynamic balance, was used to extract information of deep mineralization or mineralized ion by using artificial electric field, then the metallogenic prognosis was carried out to determine the prospecting target area. Through the comprehensive analysis of geo-electrochemical anomaly in Huadong zinc deposit area, there is obvious Zn, Pb, Sb and Ag anomalies in the upper part of concealed orebodies, the abnormal position is consistent with known geological orebodies, which indicated that the geo-electrochemical extraction method has sounding prospecting significance for the deep ore body.Based on the anomaly characteristics, five favorable target areas were delineated for further exploration.
