Geology of the Murray Basin with Aquifer Systems and Salinity Context

300,000 km of inland southeastern Australia's Murray Basin is described in this geological summary from the Australian Ocean Data Network. The document details a thin Cainozoic sediment sequence up to 600 meters thick, containing aquifer systems linked to regional salinity problems. It outlines a structural and stratigraphic framework developed over the past 60 million years.

Use Cases

• Model groundwater flow based on described aquifer systems and confining layers.
• Assess salinity risk in agriculture based on the subsurface geology and stratigraphic framework.
• Study sedimentary basin evolution using the identified depositional sequences spanning from Paleocene to Pliocene.

Strengths

• Covers a 300,000 km area of the Murray Basin.
• Describes sediment thickness up to 600 meters and identifies major depositional sequences.
• Links geological features to contemporary agricultural and salinity challenges.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.
