| 中文摘要: |
| 为取得二连盆地额仁淖尔地区铀成矿水文地质条件,运用地下水动力学、水文地球化学、铀水文地球化学等知识,通过调查取样,分析数据,整理资料等进行研究。 研究结果表明,该地区地下水水动力特征为从西北部、东部、南部的补给区向北东部、北部的排泄区径流；地下水水化学类型以HCO3-Na、Cl-Na型水为主,pH值平均为7.95,Eh值平均为60 mV,矿化度最高7.75g/L；该地区地下水水中铀含量较高,最高值可达184μg/L,自然底数为36.36μg/L；圈定铀偏高点7个,铀增高点6个,铀异常点2个；水中铀含量与硫酸根离子含量相关性最高。该地区地下水环境有以利于铀成矿、富集。 |
| 英文摘要: |
| In order to obtain the hydrogeological conditions of uranium mineralization in Erennaoer area of Erlian Basin, the knowledge of groundwater dynamics,hydrologic geochemistry,uranium hydrologic geochemistry,etc. The results show that the hydrodynamics of groundwater in this area is characterized by run off from the north-east and north-east recharge areas of the northwest,east and south,and the hydrochemical types of groundwater are mainly HCO3-Na, Cl-Na type water with an average pH value of 7.95,the average value of Eh is 60mv,the highest mineralization degree is 7.75 g/L,the highest uranium content in groundwater is 184μg/L,the natural base is 36.36μg/L,7 high uranium spots are delineated,6 high uranium spots are delineated and 2 abnormal uranium spots are found the correlation between uranium content and sulfate ion content in water is the highest. The groundwater environment in this area is favorable for uranium mineralization and enrichment. |
