摘要
本文在总结铀矿水分散体规模的基础上,对铀矿水文地球化学代矿工作的网度要求进行了讨论,提出区调阶段的工作比例尺为1:20万—1:10万,普查阶段为1:5万—1:2.5万,详查阶段为1:1万—1:5000;在阐明各工作阶段所圈定的水文地球化学场的地质含义的基础上,讨论了中、小比例尺水文地球化学调查工作的原理、效果及技术要求。提出了在潮湿多雨地区开展水分散流找矿的合理性和优越性。指出了水分散流找矿的关键是分析方法的灵敏度和精度。在水文地球化学调查中要注意通用找矿标志和矿化度(电导)的取样分析工作。
Based on summing up the size of uranium dispersion body, the requests for sampling density in uranium hydrogeochemical prospecting are discussed in this paper, the author points out that the scales for regional hydrogeochemical survey, prospetcing survey and detailed prospecting survey are 1:200,000—1:100,000, 1:50,000—1:25,000 and 1:10,000—1:5,000 respectively. On the basis of explanation to the geological meaning of hydrogeochemical field delineated in different stage, the principle, effect and technical requests of small-medium scale hydrogeochemical prospecting are studied. The reason and advantage of the dispersion train prospecting in the wet and rainy regions have been advanced The author emphasizes that the key to the dispersion train prospecting is the sensitivity and precision of analytic methods The general indications and salinity (conductivity) should be paid attention to in hydrogeochemical prospecting.
