Cassiterite U–Pb and muscovite40Ar–39Ar age constraints on the timing of mineralization in the Xuebaoding Sn–W–Be deposit, western China

The Xuebaoding deposit in the Songpan–Garzê orogenic belt, western China, spatially associated with the Xuebaoding granitic complex, is a unique pegmatite-type Sn–W–Be deposit within the giant Songpan–Garzê polymetallic belt. A lack of precise geochronological constraints on the timing of mineralization for this deposit has precluded definitive statements relating to a genetic link between ore formation and granitoid intrusion, up to now.
