Triassic Environmental Sequence in the Canning Basin, Western Australia

A review of lithology, sedimentary structures, and palaeontology subdivides the Triassic system in the Canning Basin into four environmental episodes. The sequence records a transgression culminating in the Smithian, a regression beginning in the Spathian, and a trend to increasing aridity correlated with the withdrawal of the Blina Sea. The dataset is provided by the Australian Ocean Data Network and was last updated on 2026-06-27.

Use Cases

• Modeling Triassic basin evolution based on described environmental episodes.
• Analyzing changes in marine biota based on descriptions of salinity-tolerant species.
• Correlating sedimentary facies with described lithology and structures.
• Studying paleoclimate trends based on the described increase in aridity and red beds.

Strengths

• Analysis is based on a review supplemented by original investigations.
• Describes a clear temporal sequence of four environmental episodes spanning the Triassic.
• Provides specific geological time references (Smithian, Spathian, Ladinian).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the Canning Basin study area.
