Polycyclic aromatic hydrocarbon (PAH) data from the McArthur River ore deposit in northern Australia. The dataset likely contains compound distributions and abundances used to infer temperature gradients and ore formation processes. It is provided by Geoscience Australia Data and was last updated in April 2026.
Use Cases
- Modeling ore-forming fluid temperatures based on PAH isomer distributions.
- Investigating the source of sulfur in ore deposits based on high-temperature transport hypotheses.
- Comparing hydrothermal petroleum signatures with conventional oil using PAH compound profiles.
- Studying paleobiological information and ancient hydrothermal system microbiology referenced in the description.
Strengths
- Data provides evidence for a specific temperature range (250-400°C) for ore-forming brines.
- Analysis is based on an 'exquisitely preserved' sediment-hosted base metal deposit, as stated in the description.
- Findings are linked to a specific geological location and published research (Logan et al., 2001).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data freshness should be verified despite the 2026 update timestamp.
