The Canning Basin in Western Australia contains a record of Triassic sedimentary environments. A review of lithology, sedimentary structures, and palaeontology suggests the system can be subdivided into four broad environmental episodes, from a riverine plain to a shallow marine embayment and then a coastal alluvial plain. The dataset is provided by the Australian Ocean Data Network and was last updated in June 2026.
Use Cases
- Modeling Triassic marine transgression and regression cycles based on the described environmental episodes.
- Analyzing paleoenvironmental changes based on the trend to increasing aridity and red bed deposition.
- Studying marine biota tolerance to reduced saline conditions based on the description of an impoverished marine community.
- Correlating sedimentary facies with the withdrawal of the Blina Sea as mentioned in the description.
Strengths
- Description provides a detailed narrative of four distinct environmental episodes spanning the Triassic period.
- Analysis is supplemented by original investigations, suggesting a foundation of primary research.
- Specific geological events and time periods (Smithian, Spathian, Ladinian) are named, providing temporal context.
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 not be directly machine-readable for analysis.
