Metallogeny of the Late Jurassic Qiucun epithermal gold deposit in southeastern China: Constraints from geochronology, fluid inclusions, and H-O-C-Pb isotopes

•Hydrothermal apatite and zircon U-Pb geochronology record the Qiucun gold mineralization occurred at ca. 161 Ma.•Fluid inclusion and C-H-O isotope data indicate a meteroic fluid source.•S-Pb isotope suggest derivation of them from the volcanic host rocks and deeper-seated crustal materials.•Qiucun represent a Late Jurassic low-sulfidation epithermal gold deposit in SE China.
