文摘
- •
Granodioritic porphyries from Gutian porphyry Cu–Mo deposit were dated at 161–158 Ma.
- •
The ore-bearing porphyries show an adakitic affinity.
- •
The porphyries originated from remelting of the thickened lower crust with multiple magma components.
- •
Significant Cu–Mo contributions include the ancient subduction melts and enriched mantle-derived sources.
