Genesis of Luobuzhen Pb-Zn veins: Implications for porphyry Cu systems and exploration targeting at Luobuzhen-Dongshibu in western Gangdese belt, southern Tibet
Fluid inclusion and S–Pb–H–O isotopes constrain origin of Luobuzhen Pb–Zn veins. Miocene high Sr/Y rock at Dongshibu has similar Hf isotopes to those at Zhunuo. Porphyry copper system would occur at Luobuzhen-Dongshibu in collisional zone. Potential porphyry Cu and epithermal Au–Ag mineralization should be targeted.
