706 wells across the Great Artesian Basin were examined, with palynology data reviewed for 407 wells containing Jurassic‒Cretaceous succession. The study by MGPalaeo and Geoscience Australia compiled existing data and sampled 20 new wells to fill knowledge gaps. It produced updated stratigraphic charts and a standardized chronostratigraphic framework for the Surat, Eromanga, and Carpentaria basins.
Use Cases
- Correlating lithostratigraphic units across jurisdictional borders based on reviewed palynology data.
- Generating consistent surfaces for aquifer and aquitard boundaries using regional chronostratigraphic markers.
- Mapping geological and hydrogeological frameworks for long-term water resource management.
- Identifying data and knowledge gaps within the Jurassic‒Cretaceous succession for targeted sampling.
Strengths
- Data review covers 706 wells across the basin, providing a broad spatial scope.
- 407 wells with Jurassic‒Cretaceous succession have reviewed palynology data down to total depth.
- New sampling targeted 20 wells across Queensland and South Australia to address identified gaps.
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 wells sampled in the Great Artesian Basin.
