In-situ hydrothermal zircon U–Pb and phlogopite 40Ar–39Ar geochronology of uranium mineralisation in Luzong ore district scientific drilling (LTZK01), Anhui Province, SE China: Constraints on the mineralisation process

•The uranium mineralisation in LTZK01 was approximately synchronous with the emplacement of host igneous rocks.•The uranium mineralisation in LTZK01 is genetically related with a medium-high temperature magmatic hydrothermal fluid.•The uranium was most likely fractionated from the felsic melt into F-rich magmatic fluids.
