Geoscience Australia Data provides a geological study on sandstone diagenesis in the Eromanga Basin of New South Wales. The data compares quartzose and volcanolithic petrofacies, detailing their authigenic minerals, porosity, and permeability. It was last updated on 2026-05-14.
Use Cases
- Modeling aquifer properties based on described porosity and permeability values for quartzose and volcanolithic sandstones.
- Studying diagenetic sequences based on the temporal order of authigenic mineral appearance detailed for each petrofacies.
- Correlating depositional environments with porosity-permeability distribution patterns as described in the summary.
- Analyzing the impact of early diagenetic clay cutans on preserving primary porosity in quartzose sandstones.
Strengths
- Provides specific average porosity (35%) and permeability (125 md) for volcanolithic sandstones.
- Provides specific mean porosity (29%) and permeability (676 md) for quartzose sandstones.
- Describes detailed diagenetic sequences and authigenic minerals for two distinct sandstone petrofacies.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is provided as PDF/HTML files, which may require extraction for quantitative analysis.
