Palynological and geochronological data from 11 tuff and 18 sedimentary core samples from the Bowen Basin, Australia. Quantitative analyses with counts up to 100 specimens were undertaken to identify plant microfossil taxa and correlate them with CA-IDTIMS dated tuffs. The dataset was published by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Correlating palynostratigraphic zones with numeric ages based on CA-IDTIMS dated tuffs.
- Analyzing the temporal span of the Dulhuntyispora parvithola zone across approximately five million years.
- Identifying and dating the Microreticulatisporites bitriangularis Subzone and Micrhystridium evansii acme event.
- Studying the distribution of APP5 and APP6 zone index species within the Bowen Basin succession.
Strengths
- Includes 29 total samples (11 tuff and 18 sedimentary core) providing a substantial basis for analysis.
- Quantitative analyses were performed with counts up to 100 specimens per sample.
- Combines palynology with high-precision CA-IDTIMS dating to attach numeric ages to stratigraphic units.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the single APLNG Meeleebee 5 well.
