Triassic Environmental Episodes in the Canning Basin, Western Australia

A review of lithology, sedimentary structures, and palaeontology suggests the Triassic system in the Canning Basin can be subdivided into four broad environmental episodes. The sequence records a slow transgression culminating in the Smithian, followed by a regression beginning in the Spathian, with minor marine incursions. The Australian Ocean Data Network published this analysis, which was last updated on 2026-04-16.

Use Cases

• Model basin evolution based on described transgression-regression cycles
• Analyze paleoenvironmental changes based on lithology and sedimentary structures
• Study paleoecology based on the described impoverished marine biota
• Correlate stratigraphic events based on the subdivision into four environmental episodes

Strengths

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

Limitations

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