Geoscience Australia Data provides a study using eustatic sea-level changes to correlate Late Permian coal sequences across the Sydney, Gunnedah, and Bowen Basins. The analysis identifies specific formations deposited during the same highstand and distinguishes tectonically influenced deposits. The dataset was last updated on 2026-04-30.
Use Cases
- Correlating terrestrial sequences with marine intercalations based on eustatic sea-level changes described in the study.
- Identifying depositional timing of coal measures across basins based on the described correlation of the Dempsey Formation and equivalents.
- Distinguishing between eustatic and tectonic influences on marine bed deposition based on the analysis of the Kulnura Marine Tongue and Burngrove Formation.
Strengths
- Correlations are cross-validated with palynological and marine macrofossil studies as mentioned in the description.
- Focuses on a specific, well-defined geological period (Late Permian) and region (eastern Australian basins).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF/HTML formats, which may require extraction for computational analysis.
