Eromanga Basin Uranium Potential Assessment with 3D Mapping and Geochemistry

Geoscience Australia's Onshore Energy Security Program investigated evidence for sandstone-hosted uranium systems in the Eromanga Basin. The assessment used a five-question framework involving a literature review, 3D basin mapping, water chemistry compilation, and whole-rock geochemistry. The dataset includes findings on potential mineralising events and favourable geological architecture across the ~1,000,000 km² basin.

Use Cases

• Identify potential uranium mineralisation zones based on described basin architecture and sandstone packages.
• Model fluid flow pathways for mineral systems using the compiled 3D map of the basin.
• Assess regional geochemical trends for uranium deposition using the compiled water chemistry and whole-rock geochemistry data.
• Evaluate the geodynamic history of the basin for mineralising events based on the literature review and space-time plots.

Strengths

• Assessment covers a large geographic area of approximately 1,000,000 km² in central-eastern Australia.
• Analysis employs a structured five-question framework addressing the complete mineralising system.
• Integrates multiple data types including 3D mapping, geochemistry, 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 freshness should be verified despite a last updated date of 2026-06-16.
