摘要
Based on the study of geology, hydrogeology and regional geophysical field characteristics of representative uranium deposit No.512 in the southern Yili basin, its multi-source information descriptive model is established, from which 512-type integrated prospecting model of sandstone-hosted uranium orefield and deposit are summarized. According to the established integrated prospecting models, the metallogenic information extraction of sandstone-hosted uranium deposits is completed in the study area. Finally, the integrated quantitative evaluation of sandstone-hosted uranium metallogenic potential is performed by using the evidence weighting method to integrate middle scale multi-source metallogenic information in the southern Yili basin, and the good prediction effect is obtained.
