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, including literature review, 3D basin architecture mapping, water chemistry compilation, and geochemical analysis. The basin covers approximately 1,000,000 km² of central-eastern Australia.
Use Cases
- Evaluate uranium mineralisation potential based on basin architecture and stratigraphic sequences.
- Model fluid flow pathways for uranium deposition using 3D geological maps.
- Identify regional redox and pH fronts for uranium transport based on groundwater hydrochemistry.
- Correlate mineralising events with periods of uplift and erosion from geodynamic reviews.
- Assess sandstone aquifer exposure and shale aquitard containment for deposit formation.
Strengths
- Assessment covers a basin area of approximately 1,000,000 km².
- Analysis employs a structured five-question framework for understanding the whole mineralising system.
- Includes multiple data types: literature review, 3D mapping, water chemistry, and geochemistry.
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 data_gov_au.
