Abstract: The Erongo area of Namibia, located in the central of Damara tectonic belt, is an important uranium metallogenic belt in the world. However, the Quaternary coverage in Namibia is heavy, which seriously affects the prospecting effect of uranium deposits. In order to find out the status of uranium resources in Namibia, we have carried out the uranium resources potential evaluation, which has made full use of and deeply excavate the existing data, delineated the prediction target area, and provided support for Chinese mining enterprises to invest overseas. Based on the systematic summary of the ore-controlling factors of the alaskite-type uranium deposits in the Erongo area of Namibia, a comprehensive information prospecting model is established. On the GeoDAS GIS platform, nonlinear theory, singularity theory and fractal filtering technology are used to extract weak and slow information such as hidden structure and aero-released uranium anomaly in this area. Based on the fuzzy evidence weight method, the comprehensive information mineral prediction is carried out, and 7 uranium prospecting areas are delineated. The validity of this prediction is verified by model test. The paper holds that there is still huge prospecting potential in the Quaternary coverage area of the Grade Ⅰ prospect area, and the grade Ⅱ prospect area also has good ore-forming conditions, which is expected to achieve a breakthrough in prospecting because of the low working degree.
