Palynological analyses from four fully cored boreholes (Woodlands-1, Manilla-1, Piangil West-2, Hatfield-1) provide a biostratigraphic framework for groundwater geology. The study, augmented by other cores and cuttings, covers sequences from the Early Cretaceous to the Middle Miocene. It was contributed by the Australian Ocean Data Network.
Use Cases
- Establishing biostratigraphic zones for groundwater aquifers based on pollen and dinoflagellate assemblages.
- Correlating marine incursion events across the basin based on dinoflagellate evidence.
- Analyzing shifts in vegetation and climate patterns from Late Oligocene to earliest Miocene based on pollen frequency changes.
- Identifying condensed sequences and correlating marine transgression pulses with global sea-level curves.
Strengths
- Analysis includes four fully cored boreholes, providing direct samples.
- Study references previously studied sequences (Oakvale-1) for broader context.
- Identifies pollen taxa with affinities to modern tropical species, which are of potential stratigraphic value.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
