Eromanga Basin Uranium Potential Assessment

Geoscience Australia's investigation assessed uranium potential across a 1,000,000 km² sedimentary basin in central-eastern Australia. The study compiled literature reviews, 3D geological maps, water chemistry, and geochemical data to evaluate five key questions about mineralising systems. This analysis was conducted under the Onshore Energy Security Program.

Use Cases

• Identify potential uranium mineralising events by correlating periods of uplift and erosion from geodynamic reviews.
• Map fluid flow pathways and favourable sandstone architectures using the compiled 3D basin map showing permeable packages bounded by shales.
• Assess regional groundwater chemistry for uranium transport mechanisms using compiled datasets showing redox and pH fronts.
• Evaluate stratigraphic sequences for uranium deposition by analyzing whole-rock and multi-element geochemistry from specific sandstone and shale units.

Strengths

• Assessment covers a vast 1,000,000 square kilometer basin area.
• Analysis framework addresses five distinct questions covering geodynamics, architecture, fluids, flow drivers, and metal deposition.
• Integrates multiple data types including 3D maps, geochemistry, and hydrochemistry.

Limitations

• Specific sample sizes, row counts, and data volumes are not provided.
• Primary data formats are PDF and HTML reports, limiting direct machine-readability.
• Geographic focus is exclusively on the Eromanga Basin in Australia.
