Uranium and Organic Carbon in Australian Shales, Proterozoic to Cretaceous

Proterozoic to Cretaceous geochemical data from Australian organic-rich shales, focusing on uranium and total organic carbon correlations. The dataset, from Geoscience Australia, was last updated on 2026-04-30. It likely contains measurements for testing the use of uranium content as a predictor for hydrocarbon potential.

Use Cases

• Predicting total organic carbon (TOC) content based on uranium concentration measurements mentioned in the description.
• Modeling hydrocarbon yield from kerogen using correlations with uranium and Rock-Eval pyrolysis data described.
• Analyzing secular and spatial variations in uranium enrichment in marine shales across different geological basins.
• Assessing the impact of diagenetic and post-depositional processes on original U-TOC correlations as discussed.

Strengths

• Focuses on a specific geochemical relationship (Uranium-TOC) with a described correlation range of two orders of magnitude (<5 to >500 ppm).
• Covers a broad geological time range from the Mesoproterozoic to the Cretaceous.
• Includes examples from multiple Australian basins (Greater McArthur, Georgina, Eromanga, Bight), suggesting spatial diversity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
