摘要
为获得鄂尔多斯盆地北部区域地下水铀水文地球化学特征,运用铀水文地球化学知识,通过调查取样,分析数据,整理资料等进行研究。结果表明,区内第三系含水亚组水中铀含量平均值最高,12.62μg/L;以区内铀含量滑动平均值1.65倍均方差值为界限,将研究区划分成1个铀水文地球化学低背景场、10个偏高背景场、3个高背景场;铀水文地球化学场与潜水矿化度、潜水阴离子场、潜水阳离子场的分布特征相吻合。
In order to obtain the characteristics of uranium hydrologic geochemistry of groundwater in the northern area of Ordos Basin,the knowledge of uranium hydrologic Geochemistry was used to study the uranium hydrologic characteristics by means of investigation,sampling,data analysis and data collation.The results show that the average uranium content in the water of the tertiary water-bearing subgroup is the highest,12.62μg/L and the limit is 1.65 times the mean square deviation of the regional moving average The study area is divided into 1 low background field,10 high background field and 3 High Geochemistry Field The distribution characteristics of uranium hydrologic geochemistry field coincide with those of mineralization degree,anion field and cation field of phreatic water.
