Metallogenic Characteristic of the Paleo interlayer Oxidation Type Sandstone hosted Uranium Deposits in Northeastern Ordos Basin
摘要
Abstract
Northeastern Ordos basin is an important metallogenic belt for sandstone type uranium de-posits in China and is rich in uranium resources.Previous study shew that uranium deposits in the area are closely related to ancient interlayer oxidation.Previously discovered uranium deposits are located in the lower member of middle Jurassic Zhiluo formation.In region,uranium deposits are apparently controlled by ancient interlayer oxidation zone.Based on the research on uranium mineralization characteristics,the author believed that the uranium mineralization was controlled by depositional characteristics,develop-ment of the ancient interlayer oxidation zone and the direction of paleo river flow,and then established the model of alteration and uranium mineralization by the summarized ore controlling factors and urani-um mineralization characteristics.It was point out that the western regions of Daying area,Nanguo Dachengliang area and Chaidenghao area is of further prospecting potential.关键词
