Description
Palynological analysis of the marine Oligocene-Miocene sequence from the Oakvale-1 corehole in the western Murray Basin, South Australia. The dataset, provided by Geoscience Australia Data, contains diverse and well-preserved assemblages of spores, pollen, and dinoflagellate cysts, with records for numerous extant Australian taxa and the first Australian fossil records for some pollen types. A quantitative zonation based on major pollen taxa frequencies divides the sequence into two major zones, with the younger zone further subdivided into four sub-zones.
Use Cases
Reconstructing past vegetation and climate based on the diverse and well-preserved pollen and spore assemblages.
Studying the evolution and paleobiogeography of specific plant families (e.g., Myrtaceae, Nothofagus, Podocarpaceae) based on their fossil pollen frequencies.
Conducting biostratigraphic correlation using the defined pollen zones and the tentative identification of the Triporopollenites bellus Zone.
Investigating marine-terrestrial linkages through the analysis of concurrent dinoflagellate cyst assemblages.
Strengths
Assemblages are described as diverse and well-preserved throughout the sequence.
Provides the first fossil record in Australia for pollen of Utricularia and Gardenia.
Includes a statistically calculated quantitative zonation with two major zones and four sub-zones.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is delivered in PDF/HTML formats, which may require extraction for computational analysis.
