- •
The Dunhuang HP granulite underwent the four stages of metamorphism.
- •
The HP granulite has a clockwise metamorphic P–T–t path.
- •
The HP granulite has a peak-metamorphic age of 431 Ma and a retrograde age of 403 Ma.
- •
The HP granulite formed by the early Paleozoic collisional orogeny.
- •
The Beishan orogenic collage underwent multiple early Paleozoic collisional processes.
