Palynological Data Review for 706 Wells in the Great Artesian Basin

Geoscience Australia's project compiled and analyzed palynological data from 706 wells across the Great Artesian Basin. The study reviewed data from 407 wells with Jurassic-Cretaceous succession and conducted new sampling in 20 wells across Queensland and South Australia. This work provides a standardized chronostratigraphic framework linking lithostratigraphic units across the Surat, Eromanga, and Carpentaria basins.

Use Cases

• Correlating stratigraphic units across jurisdictional borders based on reviewed palynology data.
• Refining aquifer and aquitard boundary models based on standardized chronostratigraphic markers.
• Identifying data gaps in Jurassic-Cretaceous succession knowledge for targeted sampling.
• Comparing different geological and hydrogeological schemes using a unified biostratigraphic framework.
• Updating regional stratigraphic charts for the Surat, Eromanga, and Carpentaria basins.

Strengths

• Data compilation covers 706 wells examined and 407 wells with reviewed palynology data.
• New sampling program filled gaps with data from 20 wells in Queensland and South Australia.
• Study applied a single consistent palynology zonation scheme (Price 1997, Partridge 2006) to legacy data.

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 within the Great Artesian Basin.
