- •
The study of Miaohou and Shanhou dike swarms indicates the transition of magmatism.
- •
The adakitic rocks (175–130 Ma) were remelted from Neoproterozoic magmatic rocks.
- •
The bimodal magmatism (~ 130 Ma) produced by inadequate mixing of different melts.
- •
The slab subduction and rollback caused the transition of regional tectonic regime.
