深穿透地球化学方法在十红滩砂岩型铀矿中的试验研究

摘要

深穿透地球化学方法在盆地及覆盖区的应用正逐步取得进展,笔者在十红滩砂岩型铀矿试验研究中,采用活动态提取技术,取得了较为理想的结果.同时,针对活动态提取目前没有标样用于质量监控这一事实,在分析过程中利用插入重复样的方法对分析质量进行相对监控,并将分析结果进行相对误差对比,总体上可认为分析结果能满足本区研究的需要.%Deep-penetrating geochemical technology is gradually making progress in the basin and covered area.In this paper,the authors conducted an experimental study of the Shihongtan sandstone-type uranium deposit by using selective leaching technology of mobile form.Many satisfactory results were obtained.Meanwhile,as the selective leaching technology of mobile form currently has no standard sample for the quality control,the authors tried to insert duplicate samples in the analytical method of analyzing the relative quality monitoring,and the analytical results performed the relative error comparison.It is shown that in general the results of analysis can mcet the need of the study area.
