Jurassic-Cretaceous Sandstone Diagenesis and Porosity in the Eromanga Basin

Jurassic and Lower Cretaceous sandstones from the Eromanga Basin in New South Wales are analyzed for diagenetic processes and petrophysical properties. The dataset, sourced from the Australian Ocean Data Network, includes measurements of core porosity and permeability for quartzose and volcanolithic petrofacies, detailing authigenic mineral sequences and pore-type distributions. It was last updated on 2026-04-10.

Use Cases

• Modeling aquifer potential based on described primary porosity preservation in quartzose sandstones
• Correlating depositional environments with porosity-permeability patterns as mentioned in the description
• Analyzing diagenetic sequences and authigenic mineralogy for sandstone reactivity studies
• Investigating pore-type distribution (micropores vs. macropores) in volcanolithic sandstones

Strengths

• Includes specific mean porosity (29%) and permeability (676 md) values for quartzose sandstones.
• Provides detailed diagenetic sequences for two distinct sandstone petrofacies.
• Correlates petrophysical properties with depositional environments and lithofacies.

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 the Eromanga Basin study area.
