Nimrod Complex is only exposed Precambrian basement in Ross Sea sector of Antarctica.
- •
Major crust-forming events at ∼3.1, ∼2.5 and ∼1.7 Ga.
- •
Sedimentary protoliths of Argosy Schist are mostly Neoproterozoic in age (⩽1050 Ma).
- •
1.7 Ga events include magmatism, deep-crustal metamorphism, and eclogite formation.
- •
Key part of Mawson Continent, assembled during Nuna-Rodinia transition.
