Late Permian Coal Measures Correlation via Sea-Level Change in Eastern Australia

Eustatic sea-level changes correlate Late Permian coal sequences across the Sydney, Gunnedah, and Bowen Basins. The Dempsey Formation, Black Alley Shale, and MacMillan Formation were deposited during the same highstand, while the Kulnura Marine Tongue and lower Burngrove Formation are tectonic. This dataset, hosted by the Australian Ocean Data Network, indicates coal deposition began later in the Bowen Basin than in the Sydney and Gunnedah Basins.

Use Cases

• Correlating stratigraphic sequences based on eustatic sea-level changes described in the study.
• Analyzing the timing of coal measure deposition across different basins as indicated by the correlations.
• Distinguishing between eustatic and tectonic influences on marine bed formation using the identified formations.
• Validating palynological and marine macrofossil study conclusions with the provided correlation framework.

Strengths

• Correlations are consistent with independent palynological conclusions.
• Specific geological formations across three major Australian basins are identified and compared.
• Dataset is hosted by the authoritative Australian Ocean Data Network.

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 data_gov_au, focusing on eastern Australia.
