Description
Geoscience Australia Data provides palynological analysis results from the Oakvale-1 corehole in the western Murray Basin, South Australia. The dataset contains diverse and well-preserved assemblages of spores, pollen, and dinoflagellate cysts from the marine Oligocene-Miocene Geera Clay and Renmark Group. A quantitative zonation based on major pollen taxa frequencies has been statistically calculated for the sequence.
Use Cases
Reconstructing past vegetation communities based on the described pollen assemblages of Nothofagus, Myrtaceae, and Podocarpaceae.
Analyzing marine-terrestrial environmental linkages based on concurrent dinoflagellate cyst and pollen records.
Correlating regional stratigraphy using the identified Triporopollenites bellus Zone and the statistically derived pollen zonation.
Studying the evolutionary history of specific Australian plant taxa based on fossil records for Acacia, Gyrostemonaceae, Utricularia, and Gardenia.
Strengths
Contains diverse and well-preserved fossil assemblages described as including spores, pollen, and dinoflagellate cysts.
Includes statistically calculated quantitative zonation for the corehole sequence, enabling division into two major zones and four sub-zones.
Provides specific fossil records for extant Australian taxa like Acacia and the first Australian fossil records for Utricularia and Gardenia pollen.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for quantitative analysis.
Data is presented in PDF/HTML formats, which may require extraction for computational use.
