古河道砂岩型铀矿水文地质找矿研究

Research on hydrogeologic prospecting for paleochannel sandstone-type uranium deposit

本文根据多年来古河道砂岩型铀矿的找矿经验 ,参考国内外有关资料 ,总结了古河道砂岩型铀矿各工作阶段的水文地质工作要点和方法 ,针对古河道砂岩型铀矿与层间氧化带型铀矿不同的成矿模式和特点 ,提出了相应的水文地质工作研究重点和方法 ,并对普查阶段后的地浸评价工作进行了探讨和论述。

Based on the prospecting experiences for paleochannel sandstone-type uranium deposit obtained during recent years, and referring to related materials at home and abroad, the main points and methods of hydrogeologic work for prospecting for paleochannel sandstone-type uranium deposit in different prospecting and exploration stages are summarized in this paper. Aimed at different metallogenic models and characteristics of paleochannel and interlayer oxidation zone sandstone-type uranium deposits this paper proposes corresponding hydrogeologic research focal points and methods, and discusses the in-situ leach evaluation after the prospecting stage.
