鄂尔多斯盆地鄂托克前旗地区层间氧化带砂岩型铀矿成矿条件分析

Analysis on ore-formation conditions of interlayer oxidation zone sandstone-type uranium deposit in Etuokeqian county area,Ordos basin

本文通过对鄂尔多斯盆地鄂托克前旗地区区域地质概况、找矿目的层下白垩统志丹群华池 环河组地层岩性岩相和层间氧化带发育特征以及层间氧化带砂岩型铀矿化特征的研究, 综合分析了该区层间氧化带砂岩型铀矿成矿条件, 认为该区具有较好的铀成矿环境和找矿前景。

Based on the study achievements of regional geology,lithologic-lithofacies characteristics of the prospecting target horizon——Huachi-Huanhe Formation,Zhidan Group,Lower Cretaceous,development features of interlaver oxidation zone,as well as characteristics of sandstone-type uranium mineralization of interlayer oxidation zone,ore-formation conditions for sandstone-type uranium deposits of interlayer oxidation zone have been comprehensively analyzed in this paper.It is suggested that the ore-formation environments in the area are superior and good prospecting potential exists.
