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

Eastern Australia's Sydney, Gunnedah, and Bowen Basins contain data on Late Permian coal measures correlated using eustatic sea-level changes. The dataset, from Geoscience Australia, identifies specific formations like the Dempsey Formation and Black Alley Shale deposited during the same highstand. It was last updated on 2026-03-25.

Use Cases

• Correlating stratigraphic sequences based on eustatic sea-level changes mentioned in the description.
• Analyzing the timing of coal measure deposition onset across different basins.
• Distinguishing between eustatic and tectonic origins for marine beds like the Kulnura Marine Tongue.

Strengths

• Focuses on a specific geological period (Late Permian) and region (eastern Australia).
• Correlations are supported by referenced palynological and marine macrofossil studies.
• Data is provided by the authoritative organization Geoscience 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 Australian basins studied.
