Uranium and Organic Carbon Correlations in Australian Shales, Proterozoic to Cretaceous

Australian Ocean Data Network provides a study of uranium concentrations in organic-rich shales as a predictor for hydrocarbon potential. The data likely contains measurements of uranium, total organic carbon (TOC), and pyrolysis yields from shale samples across four Australian basins spanning the Mesoproterozoic to Cretaceous periods. The dataset was last updated on 2026-04-10.

Use Cases

• Predicting total organic carbon (TOC) content based on uranium concentration correlations described in the study
• Calibrating hydrocarbon potential of source rocks using uranium-TOC and uranium-oil yield relationships
• Analyzing the impact of geological time and depositional environment on uranium enrichment factors
• Investigating how diagenetic processes and organic matter maturation affect original geochemical correlations

Strengths

• Focuses on a specific geochemical relationship (uranium-TOC) for hydrocarbon prediction
• Covers a significant geological time range from the Mesoproterozoic to Cretaceous
• Includes examples from four named Australian basins (Greater McArthur, Georgina, Eromanga, Bight)

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to the selected Australian basins
