Permian Yessabah Limestone Sequence Analysis and Depositional Models

Eastern Australia's Permian Yessabah Limestone formation in the Manning-Macleay Basin is described. The dataset, from the Australian Ocean Data Network, details the stratigraphic sequence, depositional environment, and faunal assemblages of this crinoidal limestone unit. It was last updated on 2026-06-05.

Use Cases

• Modeling sea-level change and depositional systems based on described lowstand, transgressive, and highstand systems tracts.
• Analyzing the distribution of crinoid and bryozoan faunal assemblages mentioned in the description.
• Studying the transition from clastic to carbonate depositional environments in a shallow-marine high-energy setting.

Strengths

• Detailed geological description of a specific formation's depositional history.
• Focus on a well-defined geographic region (Manning-Macleay Basin, eastern Australia).
• Last updated date is provided (2026-06-05).

Limitations

• Row count and data scale are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as PDF/HTML documents, which may require manual extraction for analysis.
