| 摘 要： | 根据对中国西北地区典型盐湖水文地质、铀矿地质和卤水地球化学性质的调查,初步探讨了不同水化学类型盐湖铀的富集规律,以及铀在盐湖固液相中的选择性富集特征。结果表明,盐湖补给区的铀源条件,盐湖卤水（晶间卤水）的盐度（矿化度）是决定盐湖富铀的主要因素,大多数碳酸盐型盐湖中铀在固液相中的分配比远大于硫酸盐型。两类盐湖卤水和补给水中,铀主要以碳酸铀酰形式存在。浅层晶间卤水和盐湖盐类沉积物中的铀含量往往较高。

| Abstract: | Based on field survey and experimental study in hydrology,uranium geology and brine geochemistry of typical saline lakes in Northwestern China,this paper summarizes some preliminary regularity of the relationship between selective enrichment of uranium in both water and correspondant sediment in different hydrochemical setting of target lakes.It was found that uranium resources and the amplitude of evaporation and concentration is the key factors to uranium accumulation and enrichment in saline lake,while t... |
