Abstract
Basing on systematizing the predecessors’ achievements in prospecting and research on gran-ite-type uranium resources in our country for more than fifty years ,and applying research means such as geochemistry and induction of objective geological phenomena ,the geological characteristics of the granite- <br> type uranium deposits in south China are summarized as follows :The uranium-producing intrusions belong to composite massifs , the uranium-producing granites possess characteristics of intracontinental S-type granites ,large time differences are shown between mineralization and diagenesis ;ore-forming is obviously controlled by geological interfaces .Basing on understanding the dynamics processes of “source ,transpor-tation and aggregation”in the uranium mineralization ,focusing on the source of ore-forming materials and the evolution of ore-fluid system ,the granite-type uranium mineralization in south China is explained .It is believed that the source of ore-forming materials was originated from the regional Late Sinian and Early Cambiran uranium source beds ,the invasion of vein rock after large-scale magmatic activities prompted the regional fluids to locally evolve to ore-forming fluids ,which were driven by gravity and buoyancy and were transported by faults acting as important migration channels ,and the change of physical-chemical condi-tions of the fluids caused the precipitation of ore-forming materials .关键词
