在进行普查设计时,必须了解铀的水化学性质。应该考虑那些控制水化学晕形成的环境系数,还要特别注意那些给探测水化学晕造成困难的气象条件。在普查工作的设计中,包括确定区分异常样品的准则。在这方面,数据的自动化处理将是提供很大的帮助。铀和主要元素之间的单相关和复相关,以及铀对于主要元素的回归分析,特别适用于鉴别异常水样和本底水样。这些数学方法还有助于展示铀在水中分布的地球化学过程。水化学构成了从铀矿成因到普查勘探之间的重要纽带。本文介绍了同探测负异常有关的实例,还论述了尚未发现原生铀矿床的区域内某些次生铀矿床的形成条件。
The uranium chemistry of water must be understood when conducting census designs. Environmental factors that control the formation of hydrated corona should be considered, with special attention paid to those meteorological conditions that make it difficult to detect hydrated corona. The design of the census work includes guidelines for the determination of abnormal samples. In this regard, the automation of data will be of great help. Single correlation and complex correlation between uranium and major elements and uranium regression analysis of major elements are particularly useful for identifying abnormal water samples and background water samples. These mathematical methods also help to demonstrate the geochemical processes in which uranium is distributed in water. Hydrochemistry constitutes an important link between the origin of uranium deposits and the census exploration. This paper presents examples of negative anomalies associated with sounding and also discusses the conditions for the formation of some secondary uranium deposits in areas where no primary uranium deposits have been found.
