摘要
依据盆地的构造、岩性岩相、水文地质、铀源条件、铀矿化特征等方面特征,分析了西宁盆地砂岩型铀矿的成矿地质条件,确定下白垩统河口组为主要找矿目的层,初步预测了2个找矿远景区,为下一步勘查工作提供方向。
According to the characteristics of the basin structure,lithology,lithofacies,hydrogeology,uranium source conditions and uranium mineralization,the metallogenic geological conditions of sandstone type uranium deposits in Xining Basin are analyzed.The Hekou Group of the Lower Cretaceous is determined as the main prospecting target layer,and 2 prospecting areas are preliminarily predicted,which provides the direction for the next exploration work.
