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

Six sedimentary cycles, each hundreds of metres thick, are documented for the Surat Basin in Australia. The data, provided by Geoscience Australia, describes cycles from the Jurassic and Cretaceous periods, correlating them with global sea-level oscillations. The record was last updated on 2026-05-14.

Use Cases

• Modeling basin stratigraphy based on described cycles of coarse to fine sediment deposition.
• Correlating regional sedimentary sequences with global sea-level oscillations mentioned in the description.
• Reconstructing paleoenvironments (braided streams, deltas, shallow marine) from the described facies transitions.
• Investigating the interplay between global eustatic changes and local isostatic movements as noted in the data.

Strengths

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

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
