The appinite–granite association was formed from 444 ± 3 Ma to 452 ± 4 Ma.
The appinites likely originated from an ancient metasomatised mantle.
The magmatic processes include AFC, magma mingling and/or mixing.
The appinite–granite association was formed in an intracontinental regime.
The ancient enriched mantle has a significant contribution to some of the Paleozoic granitoids in South China.
