- •
Detrital zircon spectra reveal a distinct succession in the North Australian Craton.
- •
Revised correlation of the succession has implications for uranium prospectivity.
- •
Hf and O data indicate a period of juvenile crust formation at ca. 2750–2550 Ma.
- •
Hf and O data indicate that crustal reworking dominated the early Paleoproterozoic.
- •
Detrital zircon age and Hf–O isotopes suggest Gawler or Dharwar Craton sources.
