Palynological Data Review for 706 Wells in the Great Artesian Basin

706 wells across the Great Artesian Basin were examined, with palynology data from 407 wells compiled and reviewed. The study by MGPalaeo and Geoscience Australia created a standardized chronostratigraphic framework and sampled new data from 20 wells to fill knowledge gaps. It provides updated biostratigraphic information to correlate aquifer boundaries across the Surat, Eromanga, and Carpentaria basins.

Use Cases

• Correlating lithostratigraphic units across jurisdictional borders based on compiled palynology data from 407 wells.
• Refining regional chronostratigraphic frameworks using the adapted Price (1997) and Partridge (2006) zonation schemes.
• Identifying data gaps in Jurassic-Cretaceous successions to guide future sampling, as demonstrated by the new sampling of 23 key wells.
• Generating consistent surfaces for aquifer and aquitard boundaries based on key regional chronostratigraphic markers.

Strengths

• Data compilation covers 706 examined wells and includes reviewed palynology data from 407 wells.
• Study integrates legacy data with new sampling from 20 wells to address specific knowledge gaps.
• Provides a standardized framework reconciling several different historical palynology zonation schemes.

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.
