Genetic stratigraphic analysis of the Hamersley group
Total Grant Value
To test the hypothesis that original facies of Pilbara banded iron formations were carbonate-rich, new dedicated lithofacies and sequence-stratigraphic analysis of the Hamersley Province was undertaken in this project.
Key findings from the project include:
- Precursor sediments were hydrothermal muds;
- The depositional site was deep-marine; and
- The precursor sediments to BIFs were deposited by deep-marine bottom density currents.
