Northern Territory's McArthur Basin hydrogeological inventory contains descriptive attribute information for spatial groundwater features. The basin is a Paleoproterozoic to Mesoproterozoic geological formation with an estimated thickness of 10,000 m to 12,000 m, known for Proterozoic petroleum systems. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-06-04.
Use Cases
- Map groundwater management zones based on the Hydrogeology Index map and administrative boundaries.
- Assess petroleum exploration potential based on the basin's stratigraphic packages and known petroleum systems.
- Model regional groundwater flow based on the basin's structural features like the Urapunga and Walker Fault Zones.
- Study land use impacts on groundwater based on the described themes of land use and industry types.
Strengths
- Thematic grouping covers 11 distinct topics including hydrogeology, geology, and land use.
- Basin thickness is quantified as 10,000 m to 12,000 m, with potential for 15,000 m in places.
- Stratigraphy is detailed with five named depositional packages (Wilton, Favenc, Glyde, Goyder, Redback).
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 only in PDF format, which may hinder direct computational analysis.
