- •
310–290 Ma mafic–intermediate rocks were discovered in the Central Tianshan block.
- •
Late Carboniferous intrusions were emplaced in a continental arc setting.
- •
Early Permian within-plate magmatism was linked to post-collisional slab break-off.
- •
The Junggar Ocean most probably closed in the latest Carboniferous.
