Eromanga Basin Uranium Potential Assessment with 3D Mapping and Geochemistry

A study by Geoscience Australia's Onshore Energy Security Program investigating evidence for sandstone-hosted uranium systems in the Eromanga Basin. The research compiled literature reviews, constructed a 3D basin architecture map from public data, and analyzed water chemistry and whole-rock geochemistry. The dataset includes PDF and HTML files summarizing findings on potential mineralising events and favourable geological architecture.

Use Cases

• Identify potential uranium mineralising events based on the review of geodynamic settings and uplift periods.
• Model fluid flow pathways for uranium deposition based on the 3D map of basin architecture showing sandstone packages and shale boundaries.
• Assess regional groundwater chemistry for redox and pH fronts that influence uranium transport and deposition.
• Evaluate the favorability of sandstone-hosted uranium systems based on compiled lithology and stratigraphic sequence data.

Strengths

• Study applies the structured pmd*CRC five-questions framework for systematic mineral system assessment.
• Analysis covers a large geographic area, the Eromanga Basin, which spans approximately 1,000,000 km².
• Integrates multiple data types including 3D mapping, geochemistry, petrology, and literature review.

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 the focus on the Eromanga Basin.
