Jurassic-Cretaceous Sandstone Diagenesis and Aquifer Properties in the Eromanga Basin

The dataset describes diagenetic overprints and petrofacies of Jurassic and Lower Cretaceous sandstones in the Eromanga Basin, New South Wales. It includes quantitative porosity and permeability measurements, such as volcanolithic sandstones averaging 35% core porosity and quartzose sandstone averaging 29% porosity. The data was published by the Australian Ocean Data Network and last updated in 2026.

Use Cases

• Modeling aquifer performance based on porosity and permeability data for quartzose sandstones
• Analyzing diagenetic mineral sequences based on authigenic mineral descriptions for volcanolithic and quartzose sandstones
• Correlating depositional environments with porosity-permeability distribution patterns as described in the lithofacies analysis
• Studying the impact of early diagenetic clay infiltration on primary porosity preservation in quartzose sandstones

Strengths

• Includes specific quantitative measurements: volcanolithic sandstones average 35% porosity and 125 md permeability
• Provides detailed diagenetic mineral sequences for two distinct petrofacies
• Links petrophysical properties (porosity, permeability) to depositional environments and diagenetic history

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, focusing solely on the Eromanga Basin in New South Wales
