Late Permian Coal Measure Correlations Using Sea-Level Change in Eastern Australian Basins

A geological study from the Australian Ocean Data Network uses eustatic sea-level changes to correlate Late Permian coal-bearing sequences across the Sydney, Gunnedah, and Bowen Basins in eastern Australia. The analysis identifies specific formations deposited during the same highstand and distinguishes those formed by tectonic subsidence. The dataset was last updated on 2026-06 27.

Use Cases

• Correlating stratigraphic sequences across basins based on eustatic sea-level changes mentioned in the description
• Distinguishing between eustatic and tectonic controls on marine bed deposition as discussed in the study
• Analyzing the timing of coal measure deposition initiation across different basins as indicated by the correlations

Strengths

• Identifies specific correlative formations (e.g., Dempsey Formation, Black Alley Shale) across three major basins
• Integrates conclusions from palynological and marine macrofossil studies for cross-validation
• Last updated date of 2026-06-27 is provided

Limitations

• Data format is HTML/PDF, suggesting a document rather than structured data tables
• Column-level documentation is absent; field semantics must be inferred after download
• Row count and sample data are unknown, which may limit suitability assessment
