West Musgrave 3D palaeovalley point dataset ~ Base of Cenozoic depth estimates made using

Depth estimates for the base of the Cenozoic layer in the West Musgrave region of Australia, derived from airborne electromagnetic conductivity models. The data was produced by Geoscience Australia's Exploring for the Future program and standardized for the EGGS database to support future modeling under the Resourcing Australia’s Prosperity initiative. The record was last updated on May 14, 2026.

Use Cases

• Modeling palaeovalley groundwater resources based on inferred subsurface architecture.
• Integrating standardized depth estimates into regional geological models based on the EGGS database framework.
• Analyzing the base of Cenozoic stratigraphy for resource exploration based on AEM and borehole data.

Strengths

• Data originates from a national geological survey (Geoscience Australia).
• Interpretations are standardized for integration into a central database (EGGS), facilitating reuse.
• Depth estimates are derived from multiple data sources including airborne electromagnetic models, borehole data, and geologic outcrop.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
