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

Late Permian geological data from the Sydney, Gunnedah, and Bowen Basins in eastern Australia. The dataset, from Geoscience Australia, uses eustatic sea-level changes to correlate terrestrial sequences with marine intercalations. It identifies specific formations deposited during the same eustatic highstand and distinguishes those formed by tectonism.

Use Cases

• Correlating stratigraphic sequences across basins based on described eustatic sea-level changes.
• Identifying marine beds deposited during the same eustatic highstand, as described for the Dempsey Formation and Black Alley Shale.
• Distinguishing between eustatic and tectonic origins of marine intercalations, as discussed for the Kulnura Marine Tongue.
• Analyzing the temporal onset of coal measure deposition across different basins, as indicated by the correlations.

Strengths

• Correlations are consistent with independent palynological and marine macrofossil studies, as mentioned in the description.
• Focuses on a specific, well-defined geological period (Late Permian) and region (three named basins in eastern Australia).

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 specific basins studied.
