【摘要】 在前人研究的基础上,重点分析了研究区断裂体系、沉积相、油气、后生氧化等作用的特征及其对铀矿化的作用,总结其铀成矿的控矿规律。在此基础上,建立了研究区直罗组远景区预测依据,并针对主要含矿目的层直罗组下段初步圈定一级远景区3片、二级远景区1片、三级远景区2片,为鄂尔多斯盆地东北部下一步铀矿勘查工作部署提供依据。更多还原

【Abstract】 Based on research in the past,the characteristics of the fault system,sedimentary facies,oilgas,epigenetic oxidation and their effect on uranium mineralization are analyzed.According to those characteristics,the criteria of the prospect prediction are established.Three First class prospects,one Second class prospect and two Third class prospects are predicted initially in the lower member of Zhiluo formation,which will be criteria for the deployment of uranium investigation in the future.更多还原
