文摘
- •
Our granitoids originate from partial melting of the lower continental crust.
- •
Isotope compositions of the granitoids indicate mantle–crust interaction.
- •
Mantle-derived melt was from partial melting of the mantle wedge.
- •
Water from the subducted oceanic slab caused partial melting of the mantle wedge.
