706 wells across the Great Artesian Basin were examined by MGPalaeo and Geoscience Australia, compiling reviewed palynology data for 407 wells with Jurassic‒Cretaceous succession. The study provides updated biostratigraphic information in a standardized chronostratigraphic framework across the Surat, Eromanga, and Carpentaria basins. It resulted in a summary compilation, a review of zonation schemes, updated stratigraphic charts, and new sampling from 23 wells to fill data gaps.
Use Cases
- Correlating lithostratigraphic units across jurisdictions based on reviewed palynology data.
- Mapping aquifer and aquitard boundaries using consistent chronostratigraphic surfaces.
- Filling data gaps in the Jurassic‒Cretaceous succession through targeted sampling of specific formations.
- Comparing geological and hydrogeological schemes using a standardized biostratigraphic framework.
Strengths
- Data compilation covers 706 wells examined and 407 wells with reviewed palynology data.
- Study integrates legacy data with new sampling from 23 wells across Queensland and South Australia.
- Provides a single consistent palynology zonation scheme applied across the basin.
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 within the Great Artesian Basin.
