- Abstract
The superlarge continental volcanic rock-type uranium deposits, which were discovered abroad long ago, have not yet been reported up to now in China. This is an important problem that needs to be urgently solved by uranium geologists at present. In this paper, on the basis of analyzing the metallogenic settings and geological conditions of the superlarge continental volcanic rock-type uranium deposits discovered in the world along with the metallogenic characteristics of those of the same type in China, the space-time distribution patterns of continental volcanics and the metallogenic potential of main tectono-volcanic belts in China are discussed, and a synthetic conclusion has been drawn that there is a possibility to discover the superlarge continental volcanic rock-type uranium deposits in China. Moreover, it is evidenced that the Ganhang, Nanling, Yanliao, Da Hinggan Ling and other tectono-volcanic belts possess favorable geological conditions for the formation of ssuperlarge ore deposits of the continental volcanic rock type. The intersecting and overlapping locations of the aforementioned main belts with other tectono-volcanic (-intrusive) belts are the most potential areas where the superlarge continental volcanic rock-type uranium deposits would be found.
