Polycyclic aromatic hydrocarbon distributions in the McArthur River ore deposit suggest hydrothermal petroleum generation temperatures of 250-400°C. The data provides evidence for ore formation in a marine diagenetic environment and implications for exploration models. The dataset is hosted by the Australian Ocean Data Network and was last updated in April 2026.
Use Cases
- Modeling ore formation temperatures based on PAH isomer distributions.
- Investigating sulfur source mechanisms in hydrothermal systems based on high-temperature brine transport.
- Studying paleobiological information related to ancient hydrothermal microbiology.
- Refining exploration models for sediment-hosted deposits using organic geochemistry signatures.
- Comparing hydrothermal petroleum signatures with conventional oil using PAH compound profiles.
Strengths
- Data provides evidence for a specific temperature range (250-400°C) for ore-forming fluids.
- Results are applicable to exquisitely preserved sediment-hosted base metal deposits.
- Dataset integrates multiple lines of evidence: geochemical, geological, and mineralogical.
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.
