U-Pb dating and metallogenic significance of pegmatite niobium-tantalitein the Central Zone of the Dangba Pegmatite-Type Rare-Metal Deposit in the Ke’eryin Orefield, Sichuan Province

The data set consists of three parts, namely, the profile of vein XIV and XV in the middle section of Dangba deposit: the profile of exploration line 22. There are also data on U-Pb dating of samples selected from pegmatite in the middle section of columbite-tantalite: hand specimens and microscopic photos of orebody VI in Dangba deposit; Columbite-tantalite TIMA Analysis Category Map of Ore Body VI in Dangba Deposit; Representative columbite-tantalite backscattering and TIMA images of orebody VI in Dangba deposit and its LA-ICP-MS U-Pb age concordance map; Columbite-tantalite LA-ICP-MS U-Pb Dating Results of Dangba Deposit; And the statistics of metallogenic age of rare metal deposits in Songpan-Ganzi orogenic belt, and the age map of rare metal deposits in Songpan-Ganzi orogenic belt.
