赛汉高毕—巴彦乌拉地区铀矿化远景区预测探讨

The Study on Uranium Ore-forming Predication of Saihangaobi-Bayanwula Area

在研究赛汉高毕—巴彦乌拉地区区域地质背景及水文地质特征的基础上,对该地区铀成矿水文地球化学特征进行了探讨。结果表明,该地区具有相对独立、完整的地下水补给、径流、排泄系统,从盆地边缘到盆地中心具有明显从氧化环境到还原环境的水文地球化学分带特征,水中铀经历了由溶滤迁移到还原沉淀的矿化过程。在二连盐池、赛汉高毕—塔木钦地区和巴彦乌拉—白音塔拉地区有十分有利的铀成矿条件和良好的铀成矿远景。

On the basis of analysis on geological setting and hydrogeology characteristics, the uranium mineralizing hydrogeochemistry characteristics of Saihangaobi-Bayanwula area are studied in this paper. Studying results indicate that this region have a relatively independent and complete recharge, runoff and discharge of groudwater. Hydrochemistry zoning from oxidizing environment to reducing environment are obviously occurred and uranium ore-forming process is performed through in groundwater from edge to center of the basin. Very beneficial uranium mineralizing conditions and good prospective areas are exist in Erlianyanchi, Sanhangaobi-Tamuqin and Bayanwula-Baiyintala.
