Triassic Environmental Sequence in Australia's Canning Basin

Lithology, sedimentary structures, and palaeontology data subdivide the Triassic system in the Canning Basin into four distinct environmental episodes. The sequence documents a slow marine transgression culminating in the Smithian stage, followed by a regression with minor marine incursions. This review, supplemented by original investigations, was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Classify sedimentary environments using lithology and sedimentary structure data from the Fitzroy Graben.
• Model paleosalinity conditions by analyzing the impoverished marine biota tolerant of reduced saline conditions.
• Correlate trends in aridity and deposition with the withdrawal of the Blina Sea using data on red bed increases.
• Reconstruct the evolution from a riverine plain to a coastal alluvial plain using data on meandering streams and lakes.

Strengths

• Defines four distinct environmental episodes for the Triassic system.
• Analysis incorporates original investigations supplementing the review.

Limitations

• Primary data format is a PDF/HTML document, not structured tabular data.
• Specific sample counts, measurements, and geographic coordinates are not provided.
