Palynostratigraphy of Four Boreholes in the Central West Murray Basin

Palynological analyses from four fully cored boreholes in the central west Murray Basin provide a biostratigraphic framework for groundwater-related geology. The study includes data from the Woodlands-1, Manilla-1, Piangil West-2, and Hatfield-1 holes, augmented by analysis from other boreholes. It was published by Geoscience Australia Data and last updated on 2026-05-14.

Use Cases

• Correlating geological strata based on pollen and dinoflagellate assemblages mentioned in the description.
• Modeling groundwater flow by analyzing the aquitard properties of the Geera Clay facies described.
• Reconstructing paleoclimate and vegetation shifts based on described changes in pollen frequencies from the Late Oligocene to Miocene.
• Dating sedimentary sequences using the described Nothofagidites asperus and Proteacidites tuberculatus pollen zones.

Strengths

• Data is derived from four fully cored boreholes, providing direct subsurface samples.
• Analysis spans multiple geological epochs, from the Early Cretaceous to the Miocene, offering a long temporal context.
• The study references specific pollen zones (e.g., Nothofagidites asperus, Proteacidites tuberculatus) for stratigraphic dating.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes that 'resolution of the palynological zones is too poor' to correlate precisely with global sea-level curves.
