A Late Cretaceous tin metallogenic event in Nanling W–Sn metallogenic province: Constraints from U–Pb, Ar–Ar geochronology at the Jiepailing Sn–Be–F deposit, Hunan, China

The Jiepailing deposit, located in southern Hunan Province, China, is a giant Sn–Be–F deposit in the Nanling W–Sn province. The Sn–Be–F mineralization is spatially associated with the Jiepailing granite porphyry. LA-MC-ICP-MS zircon U–Pb dating of the Jiepailing granite porphyry yielded a weighted mean 206Pb/238U age of 90.5 ± 0.9 Ma (MSWD = 0.32), which is interpreted as the emplacement age of the granite porphyry. Hydrothermal muscovite yields...
