- •
Epilog of paleo-Pacific subduction is unraveled by two phases of silicic volcanism.
- •
The first phase is characterized by A-type rocks (95–91 Ma) in a NE-SW trend.
- •
The second phase is E-W trending RDA (83–56 Ma) and rift-basin suites (56–38 Ma).
- •
Plate moving direction changed <83 Ma and this subduction system closed at ∼56 Ma.
