摘要
在系统分析伊犁盆地 5 12砂岩型铀矿床成矿地质背景基础上 ,阐述了补给区、径流区和排泄区地下水水文地球化学特征 ,并由此得到矿区氧化带、矿化带地下水化学类型分别为SO4·HCO3-Na·Ca型和HCO3·SO4-Ca·Na型 ,其水化学成分演化过程与岩石中硫化物氧化和脱硫酸作用有关 ,水化学类型为铀矿化地段的确定提供了证据。
The geochemistry characteristics of groundwater from recharge area, runoff area and discharge area is described based on analytical result of geological background of sandstone type of uranium deposit No.512 in Yili basin in this paper. Chemical types of groundwater in oxidation zone and mineralization zone are SO 4·HCO 3-Na·Ca and HCO 3·SO 4-Ca·Na respectively, And their evolutional procedure is concerned with oxidation of sulfide and desulphuric acid. The evidence to decide uranium mineralization is provided by geochemistry characteristics of groundwater.
