- •
Zircon ages explain the crustal composition of a seismic transect across Inner Mongolia.
- •
The middle crust comprises Proterozoic mafic and felsic gneisses.
- •
The lower crust forms a late Archaean granulite-facies assemblage.
- •
The deep crust of the southern CAOB and the northern NCC have a similar provenance.
