Origin of the Dongbulage Mo–Pb–Zn deposit in the Great Hinggan Range, northeast China: Geological, molybdenite Re–Os dating, fluid inclusion, and C–H–O–S–Pb isotope constraints

•The mineralization in the Dongbulage deposit occurred at 162.1 ± 1.3 Ma.•The early sulfide minerals were derived mainly from magmatic–hydrothermal fluids.•The late sulfide minerals were strongly affected by the surrounding strata materials.•Fluid boiling and mixing were key factors in ore precipitation.
