Geology of the Murray Basin, Southeastern Australia with Aquifer Systems

A geological summary of the Murray Basin, covering its structural and stratigraphic development over the past 60 million years. The document, from Geoscience Australia Data, describes a basin extending over 300,000 km² with Cainozoic sediment sequences up to 600 meters thick. It links subsurface geology to hydrogeological systems and salinity problems affecting the region's agriculture.

Use Cases

• Model regional aquifer systems and groundwater flow based on described stratigraphic sequences and confining layers.
• Assess salinity risk and its impact on agriculture based on the described subsurface geology and groundwater recharge mechanisms.
• Study basin evolution and sediment deposition over geological time based on the identified Tertiary depositional sequences.

Strengths

• Covers a large geographic area of over 300,000 square kilometers.
• Describes geological development over a long temporal range of 60 million years.
• Links geological features like aquifer systems and confining layers to a contemporary environmental problem (salinity).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented as HTML/PDF documents, which may require extraction for quantitative analysis.
