Palynological Data Review of 706 Wells in the Great Artesian Basin

A 2026 report by MGPalaeo and Geoscience Australia compiles and analyzes 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 to fill knowledge gaps. It provides a standardized chronostratigraphic framework for the Surat, Eromanga, and Carpentaria basins.

Use Cases

• Correlating lithostratigraphic units across jurisdictional borders based on the compiled palynology data from 407 wells.
• Refining aquifer and aquitard boundary models based on the standardized chronostratigraphic markers.
• Mapping the Jurassic-Cretaceous succession across the Great Artesian Basin using the reviewed and updated zonation schemes.
• Identifying data gaps in regional geological frameworks to guide future sampling programs.

Strengths

• Data compilation covers 706 wells across the Great Artesian Basin, with detailed review of 407 wells.
• Includes new sampling data from 20 wells to address identified knowledge gaps.
• Standardizes multiple historic palynology zonation schemes into a single consistent framework.

Limitations

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