5.The comparison study of the three belts indicates although they are distinct from each other all the three belts show many common features in the aspect of the metallogeny of large-rich vein uranium deposits, i.e: the important metallogenic areas are located above the old crystalline basement; the paleo-rifting(taphrogeny)controls the development of the volcanic belt and at the same time it is favourable metallogenic tectonic environment; the occurrence of uranium deposit does not depend on the lithology of volcanic rocks; uranium metallogeny is obviously constrained by deep geologic processes and the connected fault-structural net is the necessary condition for the formation of large-rich uranium deposits.
