Eucla Basin Hydrogeological Inventory with Geological History and Spatial Features

1,150,000 square kilometres of Australia's Eucla Basin, the world's largest grouping of onshore Cenozoic marine sediments, are documented in this hydrogeological inventory. Geoscience Australia compiled descriptive attributes grouped into themes like geology, hydrogeology, and land use. The data, last updated in March 2026, details the basin's sedimentary succession and geological events from the Eocene to Pliocene.

Use Cases

• Model regional groundwater flow based on the described hydrogeology and stratigraphic units.
• Analyze land use and environmental impacts based on the inventory's thematic groupings for surface water and industry.
• Study Cenozoic sediment deposition and karstification processes based on the detailed geological history.
• Support environmental planning and management based on data themes covering groundwater use and the physical environment.

Strengths

• Covers an extensive area of approximately 1,150,000 square kilometres.
• Descriptive data is organized into 11 specific thematic groups, including hydrogeology and groundwater management.
• Documents a unique geological region containing the world's largest onshore Cenozoic marine sediments.

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 direct computational analysis.
