| Structure Characteristics and Uranium-bearing Prospect of Longwantong Sinking, Kailu Basin |
| In-situ leachable sandstone-type uranium deposits are epigenetic uranium deposits occurring in sandstones in sedimentary basins. These uranium deposits are widely distributed, and account for a significant share of the world’s uranium resources. At present they are the main industrial uranium mineralization type in China. The Songliao basin is one of the six major Mesozoic and Cenozoic basins in North China. Within the Songliao basin is the Kailu Basin, which is a typical basin for uranium deposits, particularly the Qianjiadian deposit. The uranium bearing horizon in the basin has evident geophysical characteristics, and has a good metallogenic prospect. Moreover, it is also associated with oil. This study discusses the Kailu basin in the southwest Songliao basin in Longwantong sinking. Uranium mineralization and prospect was analyzed using geophysical data. To determine the morphology and physical properties of the uranium deposit, an analysis was conducted with 3D seismic data based on the uranium objective layer and seismic characteristics. Delineating the potential locations for uranium mineralization provides a reference for subsequent uranium exploration and research in this area. |
