Regional forecasting of uranium deposits in the Republic of Niger

Abstract

The paper deals with the methodology and results of forecasting sandstone-type uranium deposits on the territory of the Republic of Niger, based on the use of a set of regional geological and geophysical materials and a new technology for spatial analysis of data by the method of group accounting of arguments. The necessary information on the genesis and localization of sandstone-type uranium deposits in the study area is briefly outlined. Examples of identification of formal geological, tectonic and geophysical features that characterize the location of known large objects of uranium mineralization are given. On the example of reference ore and ore-less objects, an identification analysis of the features is carried out, focused on determining their aggregate information content. The results of the identification analysis made it possible to assess the weights of the features used and perform a comprehensive regional forecasting of sandstone-type uranium deposits in the territory of the Republic of Niger. Based on the results of the forecast, the three of the most promising sites were identified, where detailed work on the detection of industrial uranium mineralization is recommended.
