Murray Basin Depth to Palaeozoic Basement at 1:1,000,000 Scale

A geospatial dataset representing the depth from the surface to the Palaeozoic bedrock in the Murray Basin. The polygon data was constructed using depth to basement contours at 50-meter intervals generated from drill hole data and depth to magnetic source estimates. The dataset is provided by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-09.

Use Cases

• Model subsurface geology based on depth to Palaeozoic bedrock polygons.
• Estimate resource exploration potential based on integrated borehole and magnetic data.
• Create regional geological cross-sections based on 50-meter contour intervals.
• Validate geophysical interpretations based on the methodology from the Gold Undercover report.

Strengths

• Data is derived from two integrated sources: drill hole data and depth to magnetic source estimates.
• Contours are provided at a detailed 50-meter interval.
• Methodology is documented in a referenced technical report (Gold Undercover report 21).
• Available under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Murray Basin region.
