- •
The QMS adakitic granodiorites and their MMEs formed at ~ 430 Ma.
- •
The MMEs are cumulate rocks formed at earlier stages of the same magmatic systems.
- •
The QMS adakitic granodiorites resulted from fractional crystallization dominated by mineral assemblages represented by the MMEs.
- •
They sourced from partial melting of the ocean crust together with recycled terrigenous sediments during continental collision.
