Abstract: Xiangshan uranium ore field is an important uranium production base in China. In this study, the author use 3D NLCG inversion method to understand the geophysical characteristics of Xiangshan uranium ore field and locate the favorable positions of uranium mineralization in Xiangshan area. The results show that there are three distinct layers in the subsurface, the first layer with high resistivity anomaly is the Lower Cretaceous Ehuling Formation, the second layer with low resistivity anomaly is the Lower Cretaceous Daguding Formation, and the third layer with high resistivity anomaly is the Mesoproterozoic basement metamorphic rock. Combined with the geological conditions and well logs, the resistivity of the first metallogenic interface between the first layer and the second layer is about 2 000 ��·m, and the resistivity of the second metallogenic interface between the second layer and the third layer is about 500 ��·m. According to the resistivity of the two metallogenic interfaces, the morphological characteristics of the metallogenic interface in the survey area varies with locations. The southwestern part of the first metallogenic interface is well preserved, and the southern part is obviously cut by faults. The second metallogenic interface is well preserved in the central part, and the edge is missing. The combination of faults and metallogenic interfaces is defined as the favorable areas of mineralization, therefore, the favorable area of the first metallogenic interface is the central and southern part of the survey area, and the favorable area of the second metallogenic interface is located at the edge of the survey area.
