Prospecting model for super-large size uranium deposit and prospecting assessment in Fujian, Jiangxi and Guangdong Provinces

Uranium deposits which are located in Streltsov of Russia, Dornod of Mongolia and Xiangshan of China respectively are considered to be the largest volcanic uranium deposits in Meso-Cenozoic basin in the world. Their geologic setting, mineralization characteristic and ore-controlling factors have been summarized and multi-information comprehensive prospecting model for searching for large and super-large scale uranium field have been established. Based on the established model, uranium metallogenic prospect in Meso-Cenozoic volcanic basins located in Nanling districts of Fujian, Jiangxi and Guangdong provinces, China, has been evaluated. According to structures in depth, volcanic and post-volcanic phase structure characteristics and regional geochemistry field analysis, above districts are considered not to be favourable for forming large and super-large scale uranium field. But large or medium and small scale volcanic uranium deposits can be found in local favourable districts. In the light of above-mentioned, further reconnaissance should lay emphasis on Changpu basin and Renju basin
