Six sedimentary cycles, each hundreds of metres thick, have been identified in the Surat Basin, corresponding to nine global sea-level oscillations. The dataset, provided by the Australian Ocean Data Network, describes the depositional environments from braided streams to shallow marine settings during the Jurassic and Cretaceous periods. It was last updated on 2026-06-27.
Use Cases
- Modeling basin-scale depositional sequences based on described cycles of high-energy and low-energy sedimentation.
- Correlating regional stratigraphy with global sea-level curves based on the described nine oscillations.
- Reconstructing paleoenvironments (e.g., streams, swamps, deltas, marine settings) based on described sediment types and facies.
- Analyzing the impact of local isostatic movements on the sedimentary record as mentioned in the description.
Strengths
- Describes six distinct, thick sedimentary cycles with specific environmental interpretations.
- Links basin-scale observations to nine global sea-level oscillations, providing a broader context.
- Explicitly discusses geological processes like eustatic falls and rises, and local isostatic movements.
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 HTML and PDF formats, which may require parsing to extract structured data.
