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

Australian Ocean Data Network hosts data from a study dating Permian plant microfossil zones in the Bowen Basin, Australia. The dataset combines palynological analysis of 11 tuff and 18 sedimentary core samples with CA-IDTIMS dating to attach numeric ages to palynostratigraphic units. This work aids the correlation of palynofloras and economic coal-bearing sequences.

Use Cases

• Calibrating Permian spore-pollen zones (e.g., APP5, APP6) based on CA-IDTIMS tuff ages mentioned in the description
• Correlating regional coal-bearing sequences based on dated palynostratigraphic units
• Refining the temporal range of index species and acme events like Microstridium evansii
• Assessing the proximity of palynozones to the Permian-Triassic boundary based on the described age span

Strengths

• Integrates two precise methodologies: palynological analysis and CA-IDTIMS dating
• Focuses on a specific, economically significant basin (Bowen Basin) with terrestrial and marine sediments
• Identifies key index species and acme events, providing biostratigraphic anchors

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/temporal bias inherent to a single core sample (APLNG Meeleebee 5)
