摘　　要：文章通过区域资料、钻探资料以及邻区同层位地层对比的方法初步讨论了该区铀矿化特征和成矿前景。在此基础上认为该区缺失上白垩统,下白垩统新民堡群可以分为上下两个岩组,同时该区有两种铀矿化类型——泥岩型和砂岩型,其中砂岩型铀矿化在是新发现类型。分析后认为,对该区的砂岩型铀矿化特征、白垩系地层层序和沉积相划分、覆盖区的探索是下一步铀矿找矿工作的重点,该区找矿前景较大。Based on the integration of previous research achievements including field geological investigation,drill data and stratagraphic correlation,the Lower Cretaceous strala and uranium mineralization in Qingshan area are discussed.The Upper Cretaceous chalk stratum is lack,the Lower can be divided into two rock groups,simultaneity there are two kinds of uranium mineralization types,i.e.sandstone-type and lutyte-type.The sandstone type is the first time to be discovered in this area.
