Sedimentary Cycles in the Surat Basin Linked to Global Sea-Level Changes

The Surat Basin in Australia contains six sedimentary cycles, each hundreds of metres thick, from the Jurassic and Cretaceous periods. The cycles are described as resulting from global sea-level oscillations, with depositional environments ranging from braided streams to shallow marine settings. This dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling sedimentary basin evolution based on described cycles of high-energy deposition followed by finer sedimentation.
• Correlating regional stratigraphy with global sea-level oscillations based on the described temporal correspondence.
• Analyzing depositional environment transitions (e.g., from braided streams to deltas) based on the described sediment sequences.
• Investigating the impact of local isostatic movements on the sedimentary record as mentioned in the description.

Strengths

• Describes six distinct sedimentary cycles, each hundreds of metres thick, providing a structured geological framework.
• Links basin-scale cycles to nine global sea-level oscillations, offering a comparative context.
• Specifies depositional environments (e.g., braided streams, deltas, shallow marine) for different cycle phases.

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.
