Triassic Sediment Provenance Analysis for Australia's Roebuck Basin

The Roebuck Basin on Australia's North West Shelf contains Paleozoic to recent sedimentary rocks. This dataset provides U-Pb detrital zircon dating analyses from offshore petroleum well cuttings, aiming to clarify sediment origins and reservoir quality for the Triassic Keraudren deltas. The data was published via the Australian Ocean Data Network and was last updated on 2026-06-04.

Use Cases

• Model sediment transport pathways based on detrital zircon age spectra and grain shape analysis.
• Assess reservoir quality potential for the Triassic Upper and Lower Keraudren deltas based on provenance interpretations.
• Reconstruct paleogeographic settings by integrating zircon data with seismostratigraphic interpretations of clinoforms and submarine canyons.
• Identify sediment source regions by analyzing zircon data suggesting contributions from Australia's interior and reworked Permian sediments.

Strengths

• Analysis includes U-Pb detrital zircon dating, a precise geochronological method.
• Data integrates multiple analytical approaches, including zircon grain shape (roundness) analysis and seismostratigraphic interpretations.
• Focuses on a region of renewed exploration interest following recent hydrocarbon discoveries in the Bedout Sub-basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may require extraction and structuring for analysis.
