Late Permian Palynozones and Dated Tuffs from the Bowen Basin, Australia

The Bowen Basin in Queensland, Australia, is the focus of this dataset from Geoscience Australia. It likely contains results from palynological analysis and CA-IDTIMS dating of 11 tuff and 18 sedimentary core samples from the APLNG Meeleebee 5 well. The work attaches numeric ages to palynostratigraphic zones, aiding correlation of coal-bearing sequences.

Use Cases

• Calibrating the temporal span of the APP5 spore-pollen zone based on CA-IDTIMS tuff ages.
• Correlating regional coal-bearing sequences using the identified palynostratigraphic units.
• Refining the age estimates for the Microreticulatisporites bitriangularis Subzone and Micrhystridium evansii acme event.
• Studying the distribution of index species like Dulhuntyispora parvithola across a five-million-year interval.

Strengths

• Integrates two distinct analytical methods: palynology and high-precision CA-IDTIMS dating.
• Based on 29 physical samples (11 tuff, 18 sedimentary) from a specific well core.
• Quantitative palynological analyses were performed with counts up to 100 specimens.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF, DOCX, and HTML formats, which may require extraction for structured analysis.
