Diagenetic analysis of Jurassic and Lower Cretaceous sandstones from the Eromanga Basin in New South Wales. The dataset likely contains measurements of core porosity and permeability for quartzose and volcanolithic petrofacies, detailing authigenic mineral sequences and pore types. It is hosted by the Australian Ocean Data Network and was last updated in June 2026.
Use Cases
- Modeling aquifer function based on described primary porosity and permeability values.
- Correlating depositional environments with porosity-permeability distribution patterns as mentioned.
- Studying diagenetic sequences, such as the order of authigenic mineral appearance in different sandstone types.
- Analyzing the impact of early diagenetic clay cutans on inhibiting quartz cementation and preserving porosity.
Strengths
- Includes specific mean porosity (29%) and permeability (676 md) values for quartzose sandstones.
- Provides detailed mean porosity (35%) and permeability (125 md) values for volcanolithic sandstones.
- Describes distinct diagenetic pathways and authigenic mineral sequences for two major petrofacies.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- File formats are HTML and PDF, which may require extraction to access structured data.
