摘　　要：黄土覆盖区找矿预测评价历来是地质找矿工作的难点。物化探方法具有效率高、易操作、指导找矿针对性强等特点,多种物化探方法可以相互引证,能有效弥补单一物化探资料难以合理解释的不足。以红花沟金矿黄土覆盖区的找矿预测研究为例,系统介绍了热释汞量法和EH4连续电导率剖面测量方法从平面和剖面的三维尺度上对测区进行综合探测的结果。实践证明,这一方法体系是行之有效的。It is always very difficult to forecast concealed ore body in loess overburden area.Comprehensive geophysical and geochemical prospecting methods are superior to ordinary geological methods in forecasting concealed orebody.In order to acquire effective information on three-dimensional space,the paper systematically presents the prospecting result using thermal-release mercurimetry and EH4 conductivity image system in Honghuagou gold deposit.Practice shows that the integrated methods are very effective.
