Daly Basin Hydrogeological Inventory with Geological Unit Descriptions

The Daly Basin in Australia is a geological formation of Cambrian to Ordovician rocks, approximately 170 km long and 30 km wide. This dataset from Geoscience Australia contains descriptive attribute information for spatial groundwater features, grouped into themes like hydrogeology, geology, and land use. It was last updated on 2026-04-30.

Use Cases

• Model groundwater flow and storage based on descriptions of the primary aquifer units like the Tindall Limestone and Oolloo Dolostone.
• Analyze geological history and depositional environments based on the described transitions between carbonate and siliciclastic rock units.
• Assess land use and groundwater management interactions based on the thematic grouping of attributes like environment and industry types.
• Map regional hydrogeological features based on the associated spatial groundwater index referenced in the description.

Strengths

• Description provides specific geological dimensions: the basin is approximately 170 km long and 30 km wide.
• Includes detailed stratigraphic descriptions of key groundwater units like the Daly River Group and its three constituent formations.
• Data is structured around defined thematic groups such as Hydrogeology, Geology, and Groundwater management.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may complicate automated analysis.
