摘要
赣北一个隐覆红盆地，上部为30～50m厚的第四系覆盖层，下部为第三系红砂岩，找水困难。采用土壤吸附汞测量和直流激电法找水，通过分析、总结测区地下水的赋存特征，明确找水方向，优选出好的找水区段，取得了良好的效果。该地已成为一个中型地下水源地，日产水量3万t以上。由此可见，物化探方法结合使用，是红层地区寻找地下水资源的一种行之有效的手段。该方法的特点是经济、快速、方便，在厚覆盖区反映能力强，具有广泛的应用前景。
There is a concealed red basin in northwestern Jiangxi, which is overlain by Quaternary sediments 30 -50 m in thickness and underlain by Tertiary red sandstone. The water-prospecting work is very difficult in that area. Using soil absorbed mercury measurement and direct current IP method, the author analyzed and summed up the mode of occurrence of underground water in that area, deteeted water-prospecting orientation and optimized favorable ore-searching sectors, which yielded excellent result. Now this area has become a medium-size underground water source, with daily water production of over 30 000 tons. It is thus concluded that the combination of geophysical and geochemical methods is an effective means in search for underground water. Such a means is characterized by cheapness, rapidness, easy operation and high penetrating capacity in thick overburden areas, thus having extensive application vista.
