Sedimentary Cycles in the Surat Basin Linked to 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 in a document from the Australian Ocean Data Network, last updated in 2026. The data likely contains detailed geological interpretations of depositional environments and their relationship to eustatic changes.

Use Cases

• Modeling sedimentary basin response to sea-level change based on described cycles of coarse to fine deposition.
• Correlating regional stratigraphy with global events based on the correspondence between six basin cycles and nine global oscillations.
• Analyzing depositional environment transitions based on described shifts from braided streams to marine settings.
• Studying the impact of local isostatic movements on stratigraphic records as mentioned in the description.

Strengths

• Describes six distinct, thick sedimentary cycles with specific environmental interpretations.
• Links basin-scale cycles to nine global sea-level oscillations, providing a macro-scale context.
• Document is hosted by the authoritative Australian Ocean Data Network.

Limitations

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