Abstract:Rhenium is an important dispersed element, which is mainly applied in fields such as national defense, aerospace and petrochemical engineering. The key point is that of rhenium is irreplaceability in these fields. However, systematic research work of rhenium deposits in China has not been carried out so far. Based on the systematic review of rhenium mineral resources exploration and scientific research achievements in China, the resource characteristics and metallogenic regularity of rhenium deposits in China are preliminarily summarized, and guides to prospecting of rhenium deposits are discussed. According to this study, rhenium resources are widely distributed in China, with great resource potential and prospecting prospect. In this paper, rhenium deposits in China are divided into 8 types including porphyry type, skarn type, and carbonatite vein type and so on. Among them, porphyry type, skarn type and carbonatite vein type are the most important, accounting for more than 90% of the total estimated resources. The rhenium mineralization can be developed from the Paleoproterozoic to the Cenozoic. The resources formed in the Himalayan period are the largest, followed by the Yanshanian, Indosinian and Caledonian periods, appearing a trend that the younger the rhenium age is, the more resources the rhenium will be. The endogenous rhenium deposits are divided into 25 rhenium- forming belts, of which Gangdese rhenium- forming belt and eastern Qinling rhenium- forming belt are the most important. The prediction types of rhenium deposits are divided into 5 types including porphyry type, skarn type, magmatic hydrothermal vein type, continental sedimentary type and marine sedimentary type. The favorable ore- prospecting areas of each prediction type are analyzed, the guides to prospecting is pointed out, and the suggestions for future rhenium resources investigation and industry development are put forward.
