摘　　要：松辽盆地北部是全国重要的铀矿产区,地下水为地区铀矿的寻找提供了有效信息。以地下水为研究对象,采集并测定了松辽盆地北部不同地理位置的地下水样品,通过分析样品中的铀含量,试图探索出地下水中铀含量与地表铀矿脉出露程度之间的可能关系。研究结果显示:地下水的铀含量与铀矿位置的空间分布密切相关,铀矿脉出露较多的地区地下水铀含量也较高;地下水的径向流动性可以反映出铀矿脉的延伸方向,从而协助确定铀矿的勘探方向和范围;地下水的水化学性质,如溶液酸碱度、氧化还原电位等,也在一定程度上影响了地下水中的铀溶解与迁移,这为铀矿脉的寻找提供了更多的科学依据。因此,松辽盆地北部的地下水对铀矿找矿具有重要的指导意义。希望该研究成果能为松辽盆地北部及其他类似地区的铀矿找矿工作提供有益参考。The northern part of the Songliao Basin is an important uranium mining area in China,and groundwater provides effective information for regional uranium prospecting.In this study,groundwater is taken as the research object,groundwater samples from different locations in the northern Songliao Basin are collected and measured.By analyzing the uranium content in the samples,this paper attempts to explore the possible relationship between the uranium content in groundwater and the degree of surface uranium vein exposure.The results show that the uranium content in groundwater is closely related to the spatial distribution of uranium deposits.The uranium content in groundwater is also higher in areas with more uranium ore veins,and vice versa.In addition,the radial flow of groundwater can reflect the direction of uranium vein extension,thus helping to determine the direction and scope of uranium exploration.At the same time,groundwater chemical property,such as pH and oxidation-reduction potential,also affects the dissolution and migration of uranium in groundwater to a certain extent,which provides more scientific basis for the search of uranium ore veins.Therefore,the groundwater in the northern Songliao Basin is of great significance for uranium prospecting.It is hoped that the research results can provide useful reference for uranium prospecting in the northern Songliao Basin and other similar areas.
