地电化学集成技术在黑龙江金厂金矿的应用研究及找矿预测

Applied Research and Prospecting Forecast of Integrated Technologies of Geoelectrical Chemistry in Jinchang Gold Mine,Heilongjiang Province

为解决金厂矿区深边部找矿问题,在矿区南部穷棒子沟西侧地段开展了以地电提取法为主,土壤离子电导率测量法和土壤吸附相态汞法为辅的地电化集成技术进行深部找矿预测研究。根据金厂矿区典型的成矿地质构造特征,地电化学综合异常分布形态特征与已知的隐爆角砾岩筒、环状、放射状等赋矿构造特征极为相似,综合找矿标志,结合化探异常及已知探矿工程揭露情况,圈定了Ⅰ、Ⅱ、Ⅲ号异常靶区。认为地电化学集成技术在该区寻找隐伏金矿具有经济、快速、有效的特点,应用前景广阔。

In order to find out the deep hidden gold mine in Jinchang gold deposit,the integrated methods of geo-electrical chemistry of geoelectrochemical extraction,soil-ion conductivity and the mercury absorbed in soil are applied in the southern of the ore district,the west of Qiongbangzigou area.According to the mining of typical oreforming geological characteristics,the distribution characteristics of electrochemical anomalies and the known structures of hidden explosive breccia pipe,ring,radial in which gold mine being are very similar.Composited prospecting criteria,combined with geochemical anomalies and known works to expose cases,theⅠ,Ⅱ,Ⅲ Anomaly targets are delineated.The view that integrated electrochemical methods are used in looking for hidden gold in the area is of economic,fast and effective feature,and it will be used widely.
