Palynological Data Review of Wells in the Great Artesian Basin

706 wells were examined across the Great Artesian Basin as part of a project commissioned by the Australian Government. The study compiled reviewed palynology data from 407 wells with Jurassic-Cretaceous succession and sampled new data from 20 wells in Queensland and South Australia. This work by MGPalaeo and Geoscience Australia provides updated biostratigraphic information in a standardized chronostratigraphic framework.

Use Cases

• Correlating lithostratigraphic units across jurisdictional borders based on reviewed palynology data.
• Refining regional chronostratigraphic frameworks for aquifer mapping based on standardized spore pollen and marine zonation schemes.
• Identifying data and knowledge gaps in the Jurassic-Cretaceous succession to guide future sampling efforts.
• Updating stratigraphic charts for the Surat, Eromanga, and Carpentaria basins using compiled legacy and new sample data.

Strengths

• Data compilation covers 706 examined wells and 407 wells with reviewed palynology data.
• Study integrates multiple palynology zonation schemes into a single consistent framework.
• New sampling targeted specific geological formations across 23 key wells in the Surat and Eromanga 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 data_gov_au, focusing on the Great Artesian Basin.
