Research on geological modeling and integrated prognosis technologies for uranium deposit

Due to continuously rapid development of China's national economy, the demand on energy is increasing urgently, therefore, nuclear power become one of the necessary to the sustainable development of China's future energy. With more and more effort on uranium exploration, undiscovered uranium mineralization near surface and in subsurface is getting less, and it is more and more difficult to find U deposit directly by traditional surface survey. To meet the higher demand in the evaluation and prognosis of U resources, this paper introduces detailedly and systematically the uranium geological modeling and the prognosis technologies through integrated geological data. Guided by geodynamics, metallogenic dynamics and U metallogenetic theory, the geotectonic, geophysical, geochemical and remote sensing data of the known U deposits has been studied to summarize the prognosis factors and build geological models of U deposits. The model and prognosis factors are then transformed into evaluation and prognosis model in GIS. With GIS we can, estimate U resource amount in analogy districts in the outlined U metallogenetic prognosis zone. All the above study have resulted in an integrate set of operating method and technical flow for U resource potential evaluation. (author)
