- •
Shuikoushan granodiorites were generated from dehydration-melting of amphibolite, coupled with fractional crystallization.
- •
The middle/lower crust beneath the Jiangnan orogen as the source of the Shuikoushan granodiorites.
- •
The detachment of mafic residues after dehydration-melting was triggered by mantle upwelling.
