Research on the Main Prospecting Criteria for Sandstone Type Uranium Deposits in Northern China
Based on the study of six uranium resource bases with a capacity of over 10 000 tons in major basins in northern China,including Ili,Tuha,Bayingobi,Ordos,Erlian,and Songliao,this article studies the mineralization characteristics of typical sandstone uranium deposits from the perspective of spatiotemporal characteristics of uranium bearing basins,regional geology,and deposit geology.Four prospecting criteria for sandstone uranium deposits are obtained,including basin characteristic criteria,target layer sand body criteria,sand body geochemical environment criteria,and trace element criteria.Through these criteria,it is possible to more effectively inspire exploration ideas and create exploration methods in uranium exploration practice.Based on the information of exploration criteria,the exploration direction can be determined,mineralization anomalies can be traced,and ultimately industrial sandstone uranium deposits can be implemented.
