- •
Gray gneisses in North Wulan terrane record Mesoproterozoic trondhjemite magmatism.
- •
The precursor magma was generated in a continental rifting setting.
- •
Geodynamics is identical to that of coeval mafic rocks in Tarim and Yangtze Cratons.
- •
Tectonics was correlated to initial breakup of the supercontinent Columbia.
