Sydney Basin Hydrogeological And Geological Inventory

The Sydney Basin in Australia contains a hydrogeological inventory with descriptive attributes grouped into themes like location, geology, hydrogeology, and land use. The dataset, published by the Australian Ocean Data Network, describes rock formations from the Late Carboniferous to Middle Triassic periods and includes details on coal deposits and basin structure. It was last updated in April 2026.

Use Cases

• Map groundwater management zones using administrative and hydrogeology theme attributes.
• Analyze the relationship between coal deposit locations and late Permian strata features like sandstone and claystone units.
• Model historical basin subsidence and uplift using data on tectonic events and maximum burial depths of 2000 to 3000 metres.
• Correlate surface water features with overlying sedimentary basins in river valleys and estuaries.
• Study land use and industry types in relation to physical geography and environmental theme data.

Strengths

• Data is structured into 11 specific thematic groups for systematic analysis.
• Describes a major geological basin system with a defined temporal range from the Late Carboniferous to Middle Triassic.
• Includes specific stratigraphic details, such as the Illawarra, Tomago, Newcastle, and Wittingham coal measures.

Limitations

• The dataset is provided as a PDF, limiting direct computational analysis without extraction.
• Specific row counts, column names, and sample data are unavailable, obscuring data volume and structure.
• Geographic focus is exclusively on the Sydney Basin, limiting applicability to other regions.
