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

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 activity. The dataset was last updated on 2026-04-10.

Use Cases

• Correlating stratigraphic sequences across basins based on described eustatic sea-level change events.
• Modeling depositional timing of coal measures based on the described correlations between basins.
• Distinguishing tectonically-driven marine beds from eustatically-driven ones based on the formation analysis provided.

Strengths

• Analysis correlates specific formations across three major Australian basins.
• Conclusions are cross-referenced with palynological and marine macrofossil studies mentioned in the description.

Limitations

• Data is presented as a PDF/HTML document; column-level data and row counts are unknown.
• Description metadata is limited; actual data quality requires manual inspection after download.
