Petrogenesis of the Yaochong granite and Mo deposit, Western Dabie orogen, eastern-central China: Constraints from zircon U–Pb and molybdenite Re–Os ages, whole-rock geochemistry and Sr–Nd–Pb–Hf isotopes

•The Yaochong magmatic and Mo mineralization ages are dated to be Early Cretaceous.•Tectonic collapse is suggested to have occurred in the Western Dabie orogen.•The tectonic collapse may have led to a two-stage magmatism and Mo mineralization.
