Geology, geochronology and geochemistry of the Miocene Jiaoxi quartz vein-type W deposit in the western part of the Lhasa Terrane, Tibet: Implications for ore genesis

•Highly evolved parental magma controls formation of the Jiaoxi W deposit.•New geodynamic setting for Miocene granite-related W deposits in central Lhasa subterrane.•Mantle-derived melts play an important role in mobilizing the W from crust materials.
