Palynological Data Review for 706 Wells in the Great Artesian Basin

Geoscience Australia's project compiled and reviewed palynological data from 706 wells across the Great Artesian Basin. The work standardized legacy data from 407 wells and collected new samples from 20 wells to fill knowledge gaps in the Jurassic-Cretaceous succession. This provides a regional chronostratigraphic framework linking the Surat, Eromanga, and Carpentaria basins.

Use Cases

• Correlating lithostratigraphic units across jurisdictional borders based on standardized palynology zonation schemes.
• Refining aquifer and aquitard boundary models based on chronostratigraphic markers derived from spore pollen and marine zonation.
• Identifying data gaps in the Jurassic-Cretaceous succession to guide future sampling and analysis efforts.
• Comparing geological and hydrogeological schemes across the Surat, Eromanga, and Carpentaria basins.

Strengths

• Data review covers 706 wells across the Great Artesian Basin.
• Standardized legacy data from 407 wells with Jurassic-Cretaceous succession.
• Includes new sampling results from 20 wells to address identified gaps.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is delivered as PDF and ZIP files, which may require extraction and manual processing for analysis.
