公婆泉盆地局部排泄源氧化还原属性与铀矿化关系探讨

在系统分析公婆泉盆地地质背景、水文地质条件的基础上，对该区局部排泄源氧化还原属性与铀矿化的关系进行了探讨。研究结果表明，局部排泄源的存在对铀矿化具有重要作用，当局部排泄源属于还原性质时，铀矿体常常分布于该排泄源上游；若属氧化性质，排泄源铀矿体通常位于其下游或附近。公婆泉盆地存在相对氧化和相对还原的二种局部排泄源，北骆驼泉区的沙泉沟与平沙地、麻黄沟、北骆驼泉沟排泄源之间应为有利的铀矿化地段。

The Study OF Relation Between Redox Property and Uranium Mineralization of Local Discharge Source in Gongpoquan Basin

The relation between redox property and uranium mineralization of local discharge source is studied based on geological background, hydro-geology condition of Gongpoquan basin. The results indicate that local discharge is very important for uranium mineralization. Uranium ore body usually distributes in upstream of discharge source under the circumstance of discharge source belongs to reducing property. If it belongs to oxidizing property, uranium ore body will distribute in downstream or adjacent of discharge source. there are two kinds of local discharge source in Gongpoquan basin, that is, relative oxidation and relative reduction local discharge source. In north camel spring area, beneficial uranium mineralization area should be located between Shaquangou and Pingshadi, Mahuanggou, Beiluotuoquangou.
