Palynological Data Review for 706 Wells in the Great Artesian Basin

A palynological data compilation and analysis from Geoscience Australia's groundwater assessment project. The study examined 706 wells across the Great Artesian Basin and compiled reviewed data for 407 wells with Jurassic-Cretaceous succession. This work provides a standardized chronostratigraphic framework to support regional correlation and groundwater management.

Use Cases

• Correlating lithostratigraphic units across jurisdictional borders based on reviewed palynology data.
• Refining regional chronostratigraphic frameworks for aquifer mapping based on standardized zonation schemes.
• Identifying data gaps in Jurassic-Cretaceous sequences to guide future sampling programs.
• Generating consistent surfaces for aquifer and aquitard boundaries based on key chronostratigraphic markers.

Strengths

• Data compilation covers 706 wells examined and 407 wells with reviewed palynology data.
• Includes new sampling results from 20 wells to fill identified knowledge gaps.
• Applies a single consistent palynology zonation scheme (Price 1997, Partridge 2006) for regional correlation.

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 in Queensland and South Australia.
