摘　　要：厚覆盖区找矿评价历来是地质找矿的难点。通过内蒙新巴尔虎右旗额仁陶勒盖银矿区的方法实验,认为在干旱、风成沙干扰大的厚覆盖区,选取采样深度40 cm、粒度-140目,采用离子电导率(搅拌时间在1 min以上)、热释汞(炉温取800℃)、元素活动态的水溶态和吸附态测量可以很好地发现异常。在阿敦楚鲁、哈如勒敖包远景区应用这些方法,圈定的异常比常规土壤地球化学测量异常吻合性好,浓集中心明显。The evaluation of ore-prospecting effects in thick overburden areas has long become a difficult point in geological exploration work. Based on method experiments in the Erentaolegai silver ore district of Xin Barag Right Banner, the authors have reached the con- clusion that, in arid and airborne sand thick overburden areas, anomalies can be discovered by adopting the sampling depth of 40 cm, grain size of -140 mesh, ionic conductivity with stirring time of over 1 min, heat-release mercury with temperature of 800℃ and the measurement of water-soluble state and adsorption state of the element active state. In Adunchulu and Harule Oho prospective areas, the anomalies delineated by these methods are quite consistent with those delineated by routine soil geochemical survey and have obvi- ous concentration centers.
