Palaeozoic high-grade metamorphism within the Centralian Superbasin, Harts Range region, central Australia
Dating of remnant detrital zircon from high-grade metasediments of the Harts Range Group (HRG) in central Australia shows that the sedimentary protoliths were deposited during the Neoproterozoic to Cambrian, demonstrably younger than Palaeoproterozoic metamorphic rocks of the surrounding Arunta Inlier. The inferred depositional age of the HRG indicates that it was deposited at the same time as sedimentary rocks of the former Centralian Superbasin, now represented by the Amadeus and...[Show more]
