Abstract: Xingning Basin is located in intersection area of NE direction Shaowu—Heyuan fault zone and Wuhua fault zone,the uranium metallogenic potential of the area is good,the metallogenic conditions such as strata,magmatic rock,geophysical and geochemical conditions are favorable,the metallogenic tectonic environment of the area is good,besides that,the uranium ore and anomalies are well developed in the area.Combing with the geological results of the area,the metallogenic geological conditions and metallogenic potential of the basin and its periphery are discussed.The results show that the developed locations of the secondary silicified zone or the diabase zone along the regional deep faults,especially for the intersection area that the silicified zone and intermediate—basic veins,and the superposition area of silication,hematitization,secondary uranium mineralization and various geophysical and geochemical anomalies are favorable areas for uranium metallogenic.
