Amadeus Basin Hydrogeological Inventory with Geological Unit Descriptions

An inventory of descriptive attributes for the Amadeus Basin in central Australia, grouped into themes including location, geology, hydrogeology, and land use. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-04-28. It describes a sedimentary basin with rock sequences from the Neoproterozoic to Late Devonian periods, with a total thickness ranging from 6,000 m to 14,000 m.

Use Cases

• Assess hydrocarbon source rock potential based on described geological formations like the Horn Valley Siltstone and Gillen Formation.
• Model groundwater resources and management based on the hydrogeology and groundwater themes.
• Analyze basin stratigraphy and depositional environments using the detailed descriptions of super-sequences and unit thicknesses.
• Support land use and environmental planning by integrating data on physical geography, surface water, and industry types.

Strengths

• Describes a basin with a substantial geological record spanning from the Neoproterozoic to Late Devonian, potentially Early Carboniferous.
• Provides specific thickness ranges for the overall basin (6,000 m to 14,000 m) and for individual formations, such as the Gillen Formation (up to 850 m thick).
• Groups descriptive information into 11 structured thematic categories, including Hydrogeology 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 hinder automated data extraction and analysis.
