- •
The Xuting pluton contains potassic and sodic granite.
- •
The Xuting pluton was emplaced between 2070 Ma and 2090 Ma.
- •
Both the potassic and sodic components of the Xuting pluton are A-type granites.
- •
The sodic granites are a very rare type known from only a few localities globally.
- •
The 2.2–2.0 Ga bimodal magmatic rocks along the TNCO formed in a rift setting.
