Genesis of orogenic gold systems in the Daduhe belt: Evidence of long-lived fertile mantle lithosphere as a source of diverse metallogeny on the western margin of the Yangtze Craton, China

•Both the Early Jurassic and Cenozoic gold mineralization are hosted by NNE-trending faults.•The Daduhe orogenic gold deposits have ore fluids derived from metasomatized mantle lithosphere.•The deposits have similar S-O-He-Ar isotope values to IOCG, Fe-V-Ti and carbonatite REE deposits.
