- •
Mafic microgranular enclaves are commonly present in Beiya pluton, Southwestern China.
- •
Geochemical and isotopic studies indicate a mafic-felsic magma mixing process.
- •
The underplating of mafic magmas likely supplied parts of water, sulfur and metals (Au and Cu) for the Beiya porphyry system.
