- •
Arc magmatism at Mount Brown took place at ca. 1490–1400 Ma.
- •
Granulite facies metamorphism with an near-isobaric cooling path occurred at ca. 920–900 Ma.
- •
Mount Brown represents the earliest portion of the long-lived Rayner continental arc.
- •
The tectonic evolution of the Rayner orogen might have lasted for ca. 600 Ma.
