Eromanga Basin Uranium Potential Assessment Using 3D Mapping and Geochemistry

Geoscience Australia's Onshore Energy Security Program investigated evidence for sandstone-hosted uranium systems in the Eromanga Basin. The assessment compiled literature, constructed a 3D basin map, and analyzed water chemistry and geochemistry to evaluate mineralisation potential. The dataset includes findings on basin architecture, fluid pathways, and potential mineralising events.

Use Cases

• Modeling sandstone-hosted uranium deposit formation based on described basin architecture and fluid pathways.
• Assessing regional mineralisation potential based on compiled geodynamic and geochemical data.
• Identifying prospective areas for exploration based on mapped redox and pH fronts from groundwater hydrochemistry.

Strengths

• Assessment is based on a defined five-question framework (pmd*CRC) for understanding mineralising systems.
• Covers a large geographic area, with the Eromanga Basin spanning approximately 1,000,000 km².
• Integrates multiple data types including 3D mapping, literature review, and geochemical analysis.

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; last metadata update was 2026-06-27 18:24:09.551313.
