New discovery of rare and dispersed elements Re, Se ores in Permian Wujiaping Formation of Wangcang area, Sichuan Province

Due to extremely scattered characteristics of rare and dispersed elements in the geological body, it is extremely difficult for them to form their own independent deposits.According to the study of prospecting prediction, an independent Re and Se enrichment stratum featuring sedimentation-reformation genesis was first discovered in the first member of Wujiaping Formation in Wangcang, Sichuan.By means of sparse drilling engineering in partial areas, the authors obtained 61.4 tons of rhenium and 3000 tons of selenium resources, which show that there is huge prospecting potentiality of rhenium and selenium.With the characteristics of forming stratified enrichment, the co-existence of V and Mo seams in the same formation, the existence of economical and optional ores and the probable comprehensive recovery of many elements, the area is expected to become an important metallogenic belt of new types of mineralization of shortage emerging strategic resources in China.The deposit shows such characteristics as stability of ore-bearing stratum, uniform mineralization and huge scale.
