Sedimentary Cycles in the Surat Basin and Global Sea-Level Changes

Six sedimentary cycles, each hundreds of metres thick, have been identified in the Surat Basin, corresponding to nine global sea-level oscillations. The cycles from the Jurassic and Cretaceous periods are described, detailing depositional environments like braided streams, deltas, and marine settings. This dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Modeling basin-scale sedimentary responses based on described cycles of high-energy deposition and marine transgression/regression.
• Correlating regional stratigraphy with global sea-level oscillations based on the nine identified global cycles.
• Reconstructing paleoenvironments based on described depositional settings like braided streams, swamps, lakes, and deltas.

Strengths

• Describes six distinct sedimentary cycles, each hundreds of metres thick.
• Correlates basin cycles with nine global sea-level oscillations.
• Provides temporal context spanning the Jurassic and Cretaceous periods.

Limitations

• Data is documented in PDF/HTML formats; column-level structure and sample data are unavailable.
• Row count and dataset scale are unknown, limiting suitability assessment.
• The description suggests local isostatic movements may have obscured some global signals, indicating potential data complexity.
