Timing and genetic link of porphyry Mo and skarn Pb-Zn mineralization in the Chagele deposit, Western Nyainqentanglha belt, Tibet

•Mo mineralization in the Chagele deposit took place at 61.9 ± 0.4 Ma.•Pb–Zn mineralization veins formed at 62.8 ± 0.6 Ma.•Mo and Pb–Zn mineralization constitutes a porphyry–skarn metallogenic system.•The magmatic source is from continental crust metasomatized by mantle-derived melt.•Mineralization related magma formed during the initial India–Asia collision.
