Palynostratigraphy Data from 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 geological factors related to groundwater. The study, augmented by analysis from other boreholes, covers sediments from the Early Cretaceous to the Middle Miocene. Data is provided by the Australian Ocean Data Network and was last updated on 2026-06, though the original study date is unspecified.

Use Cases

• Correlating aquifer ages based on pollen and dinoflagellate zones mentioned in the description
• Analyzing shifts in vegetation and climate from the Late Oligocene to Miocene based on pollen assemblage data
• Modeling the extent of marine incursions in the basin based on dinoflagellate evidence
• Refining regional stratigraphic frameworks using the identified palynological zones

Strengths

• Data is derived from four fully cored boreholes, providing direct stratigraphic samples
• Analysis covers a wide temporal range from Early Cretaceous to Middle Miocene
• Includes pollen taxa with affinities to modern tropical species, noted as having potential stratigraphic value

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 palynological zones is too poor to identify specific pulses of marine transgression
