Palynological Data Review of 706 Wells in the Great Artesian Basin

706 wells across the Great Artesian Basin were examined, with palynology data from 407 wells reviewed and standardized. The study by MGPalaeo and Geoscience Australia compiled legacy data and sampled 23 new wells to fill knowledge gaps in the Jurassic-Cretaceous succession. Results include updated stratigraphic charts and a consistent zonation scheme for regional correlation.

Use Cases

• Correlating lithostratigraphic units across jurisdictional borders based on reviewed palynology data.
• Refining regional chronostratigraphic frameworks to map aquifer and aquitard boundaries.
• Identifying data and knowledge gaps within the Jurassic-Cretaceous succession of the GAB.
• Standardizing diverse historic nomenclature using the Price (1997) and Partridge (2006) zonation schemes.

Strengths

• Data compilation covers 706 examined wells and includes reviewed data from 407 wells.
• Study includes new sampling from 23 key wells to address identified gaps.
• Provides a standardized chronostratigraphic framework across the Surat, Eromanga, and Carpentaria basins.

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 selected wells in Queensland and South Australia.
