- •
The Xing’an complex formed in three stages: ∼358 Ma, 309–308 Ma, and ∼294 Ma.
- •
Intermediate rocks of different ages were formed by similar petrogenetic processes.
- •
Parental magmas of granites were formed by partial melting of newly accreted crust.
- •
The Xing’an and Songnen terranes had not amalgamated before the Early Permian.
