3D Hydrogeological Framework for Australia's Great Artesian Basin and Adjacent Regions

Geoscience Australia's dataset aims to build a national 3D hydrogeological framework under the Exploring for the Future Program. The work compiles and standardizes data from thousands of boreholes, 2D/3D seismic surveys, and airborne electromagnetic sections to refine stratigraphic understanding. The current focus is on the Great Artesian Basin, Lake Eyre Basin, and Upper Darling Floodplain region, with expansion planned.

Use Cases

• Modeling groundwater system architecture based on integrated basin analysis workflows described.
• Correlating chronostratigraphic units across basins using the refined framework.
• Analyzing hydrostratigraphy for water resource management based on compiled borehole and geophysical data.
• Extending regional geological transects for the Surat, Eromanga, and Carpentaria basins.

Strengths

• Integrates data from thousands of boreholes, including stratigraphic and biostratigraphic picks.
• Incorporates multiple data sources: 2D/3D seismic and airborne electromagnetic derived conductivity sections.
• Applies a nationally consistent chronostratigraphic framework to link studies.

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 the focused study area of the Great Artesian Basin.
