摘　　要：Objective The Guangshigou uranium deposit is located in the eastern part of the Shangdan triangular domain, which is currently the most productive pegmatite-hosted uranium deposit in China. Previous studies have focused on the migration and precipitation of uraninite and biotite clusters in the uraniferous pegmatites(Li Yanhe et al., 2016; Yuan et al., 2018). However, the accurate uranium mineralization age still remains poorly constrained, thus
