Hydrothermal fluid evolution of the Jintingling gold deposit in the Jiaodong peninsula, China: Constraints from U-Pb age, CL imaging, fluid inclusion and stable isotope

•Molybdenite from gold ores has a Re-Os isochron age of ∼123 Ma and was contemporaneous with gold mineralization at ∼120 Ma.•The earliest vapor and critically homogenized fluid inclusions are recognized as magmatic fluids.•The evolution of hydrothermal fluids included fluid immiscibility and meteoric water mixing.•Fluid immiscibility and decrease in ƒS2 triggered precipitation of gold.
