| Analysis of Sandstone-type Uranium Mineralization Potential in the Zhangpengou Area, Eastern Junggar Basin |
| The Zhangpengou area is a favorable prospect for sandstone-type uranium exploration in the eastern Junggar Basin, with the Lower Jurassic Sangonghe Formation currently serving as the primary target layer. Based on comprehensive analysis of outcrops, drill cores, hydrogeological surveys, coal field and uranium exploration data, the authors classified hydrogeological units and conducted an integrated study of sandbody distribution, interlayer oxidation zones, uranium mineralization characteristics, permeability, geochemical features, and metallogenic hydrodynamic field. Guided by the theory of sandstone-type hydrogenic uranium deposits and prospecting criteria, the authors predicted uranium resources and assessed metallogenic potential and future exploration targets. The results show that: (1) The three delineated hydrogeological units possess relatively independent recharge-runoff-discharge systems, with uranium mineralization scales varying under different metallogenic hydrodynamic conditions; (2) The southern slope zone shows potential for forming medium to larger sandstone-type uranium deposits, while the northern fold zone may locally develop small deposits, and the eastern slope zone exhibits limited potential; (3) The thick sand bodies in the Wucaiwan area exhibit promising ore prospecting potential. The eastern block of the Shadong Fault (combined with the core of the Lucaogou Syncline) and the western block of the Huodong Fault (combined with the core of the Xidagou Syncline) show uranium enrichment through superimposed mineralization, representing key targets for exploration. Drilling verification has yielded positive results. |
