- •
The Jurassic intermediate-acidic intrusions formed in three stages: Early Jurassic (180–177 Ma), Middle Jurassic (171–170 Ma), and Late Jurassic (∼151 Ma).
- •
The Paleo-Pacific oceanic plate was subducted beneath the East Asian continent starting in the Early Jurassic or earlier.
- •
The generation of the Jurassic intrusions was related to subduction of the Paleo-Pacific oceanic plate.
