中国西北地区典型盐湖铀富集特征初探
Preliminary discussions on uranium enrichment in typical saline lakes in Northwestern China
摘要
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 the partition ratio of uranium content in solid and liquid in most carbonate type lakes is far more than that of sulfate type lakes. Uranium occurs as uranyl carbonate complex in recharge water and lakes of different hydrochemical type. Higher u-ranium concentration generally was found in shallow intercrystalline brine and corresponding salty deposits in saline lakes.关键词
