Post-orogenic exhumation triggers gold mineralization in the Trans-Hudson orogen: New geochronology results from the Lynn Lake greenstone belt, Manitoba, Canada

•Garnet-hosted xenotime and gold are dated at ca. 1827 Ma•Early gold veins are metamorphosed to amphibolite facies (505–689 °C)•New ages for gold mineralization also post-date metamorphism by up to 80 Myr•Post-orogenic gold mineralization is coeval with biotite cooling ages (ca. 1746 Ma)•Exhumation of the Trans-Hudson orogen triggered gold mineralization
