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, sourced from the Australian Ocean Data Network, examines correlations between uranium, total organic carbon, and pyrolysis oil yield in Australian marine shales from the Mesoproterozoic to Cretaceous periods. It was last updated on June 23, 2026.
Use Cases
- Predicting total organic carbon content based on uranium concentrations mentioned in the description
- Calibrating hydrocarbon potential of source rocks using uranium-TOC correlations described in the study
- Analyzing the impact of diagenetic processes on uranium-organic matter relationships as discussed
- Modeling spatial and secular variations in uranium enrichment in marine shales across geological time
Strengths
- Focuses on a specific geochemical relationship with potential predictive applications for hydrocarbon exploration
- Covers Australian marine shales from a wide temporal range, from the Mesoproterozoic to Cretaceous
- Description references established correlations and processes like U-TOC and U-oil yield relationships
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to data_gov_au, focusing on Australian basins
