Eromanga Basin Uranium Prospectivity Analysis And 3D Model

Geoscience Australia's study assesses sandstone-hosted uranium potential across the 1,000,000 km² Eromanga Basin in central-eastern Australia. The analysis applies a five-question framework, integrating geodynamic reviews, 3D architectural mapping, water chemistry, and geochemistry to evaluate mineralising events and fluid pathways. Findings identify three potential mineralising events in the basin's west and a prolonged event in the east.

Use Cases

• Train geological prospectivity models using features like geodynamic setting, basin architecture, and fluid flow pathways identified in the study.
• Analyze spatial relationships between uranium potential, regional redox fronts, and pH fronts mapped from groundwater hydrochemistry data.
• Validate 3D basin architecture models showing permeable sandstone packages bounded by impermeable shales for fluid containment simulation.
• Correlate periods of known uplift and erosion from geodynamic reviews with potential uranium mineralising events in the basin.

Strengths

• Analysis covers a vast geographic area of approximately 1,000,000 square kilometers in the Eromanga Basin.
• Integrates multiple data types: literature review, 3D architectural mapping, water chemistry compilation, and detailed petrology.
• Applies a structured five-question framework to assess the entire mineralising system.

Limitations

• Primary data is presented in report formats (PDF, HTML), not as a structured, queryable database or tabular dataset.
• Sample data and specific columnar features are unavailable, limiting direct analytical use without manual extraction.
• The study's findings are interpretive, synthesizing existing public data rather than providing new raw measurements.
