Uranium concentrations in organic-rich shales range from less than 5 to over 500 parts per million. This dataset from Geoscience Australia examines correlations between uranium, total organic carbon, and pyrolysis oil yield across Proterozoic to Cretaceous shales in Australian basins. It is intended for testing the hypothesis that uranium-TOC correlations can calibrate hydrocarbon potential.
Use Cases
- Predict total organic carbon content based on gamma-ray log data and uranium concentrations.
- Estimate pyrolysis oil yield using correlations with uranium content.
- Classify kerogen type and maturation level using uranium content alongside Rock-Eval parameters.
- Model the hydrocarbon potential of organic-rich shales across different geological time slices.
- Analyze the impact of diagenetic and post-depositional processes on uranium-TOC correlations.
Strengths
- Data covers a wide temporal range from the Mesoproterozoic to the Cretaceous.
- Explicitly describes uranium concentration ranges over two orders of magnitude.
- Focuses on specific Australian basins including Greater McArthur, Georgina, Eromanga, and Bight.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is in the future (2026-05-14).
