- •
Mo-bearing quartz veins at Zhifang area form an orogenic type Mo system in Qinling.
- •
Molybdenites from the Zhifang Mo system yield a mean Re–Os age of ~ 244 Ma.
- •
Sr–Nd–Pb isotopes and Re contents suggest that the fluids were sourced from old crust.
- •
Underthrusted back-arc basement beneath arc causes orogenic-type mineralization.
- •
Continental arc to back-arc transitional area accommodates orogenic type deposits.
