Daly Basin Hydrogeology and Groundwater Inventory for Northern Australia

Cambrian to Ordovician carbonate and siliciclastic rocks, formed 541 to 470 million years ago, form the primary groundwater reservoir of the Daly Basin. This dataset from Geoscience Australia provides descriptive attributes on location, demographics, geology, hydrogeology, and land use for areas bounded by spatial groundwater features. The basin stretches approximately 170 km in length and 30 km in width, shaped as a northwest elongated synform.

Use Cases

• Model groundwater flow and storage based on descriptions of the Tindall Limestone, Jinduckin Formation, and Oolloo Dolostone units.
• Assess groundwater management strategies based on grouped attributes for groundwater management and use.
• Study geological basin evolution based on the described transition from marine to peri-tidal environments.
• Analyze land use and environmental impacts on aquifers based on grouped themes for environment and land use.

Strengths

• Descriptive attributes are grouped into 11 specific themes, including hydrogeology and groundwater management.
• Provides detailed geological context for a basin approximately 170 km long and 30 km wide.
• Sourced from Geoscience Australia, a national geological survey organization.

Limitations

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