Uranium concentrations in organic-rich shales can range over two orders of magnitude, 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 in marine shales from the Greater McArthur, Georgina, Eromanga, and Bight basins. It was last updated on 2026-04-20.
Use Cases
- Predicting total organic carbon content based on uranium concentration or gamma-ray logs.
- Estimating pyrolysis oil yield (S2) from kerogen using uranium content correlations.
- Classifying kerogen type and maturation level using uranium, hydrogen index, and oxygen index data.
- Modeling the impact of diagenetic processes and hydrothermal fluids on uranium-organic carbon relationships.
Strengths
- Data spans a significant geological time range from the Mesoproterozoic to the Cretaceous.
- Analysis includes multiple major Australian sedimentary basins.
- Correlations are tested against established geochemical methods like Rock-Eval pyrolysis and Fischer retort assay.
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 is dated 2026-04-20.
