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

Palynological and geochronological data from 11 tuff and 18 sedimentary core samples from the Bowen Basin, Australia. The work was conducted by Geoscience Australia, with data last updated in March 2026. Analyses include quantitative counts of plant microfossils and CA-IDTIMS dating to attach numeric ages to palynostratigraphic units.

Use Cases

• Correlating palynostratigraphic zones based on the presence of index species like Dulhuntyispora parvithola and Microreticulatisporites bitriangularis.
• Refining the age of the Price (1997) APP5 spore-pollen zone using associated CA-IDTIMS tuff ages.
• Identifying and dating acme events, such as the Micrhystridium evansii event, within the Permian succession.
• Aiding regional correlation of economic coal-bearing sequences by combining palynology and radiometric dating.

Strengths

• Integrates two distinct data types: palynological counts and high-precision CA-IDTIMS radiometric dates.
• Quantitative analyses with specimen counts up to 100 per sample.
• Data is tied to a specific, documented geological section from the APLNG Meeleebee 5 well.

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 computational analysis.
