- •
A Permian alkaline magmatic belt is identified along the northern margin of NCC.
- •
Peralkaline-alkaline rocks yielded zircon U–Pb ages from 261 to 267 Ma.
- •
A mixing of metasomatic mantle-derived mafic magma with different amount of crust-derived magma is proposed.
- •
A Permian post-orogenic extension is proposed.
