Sandstone-Hosted Uranium Potential Assessment for the Eromanga Basin

Geoscience Australia's Onshore Energy Security Program investigated evidence for sandstone-hosted uranium systems in the Eromanga Basin, covering approximately 1,000,000 km² of central-eastern Australia. The assessment used a five-question framework involving literature review, 3D mapping, water chemistry compilation, and geochemical analysis. The study identified potential mineralising events and favourable geological architectures for uranium deposition.

Use Cases

• Identify prospective areas for uranium exploration based on described basin architecture and sandstone-shale juxtapositions.
• Model regional fluid flow pathways for mineral systems using the compiled 3D map and hydrochemistry data.
• Correlate uranium mineralisation events with periods of uplift and erosion as suggested by the geodynamic review.

Strengths

• Assessment covers a large geographic area of approximately 1,000,000 km².
• Analysis integrates multiple data types including 3D mapping, geochemistry, and hydrochemistry.
• Framework addresses the complete mineralising system through five specific questions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
