The Permian Yessabah Limestone is a thick crinoidal limestone formation in the Manning-Macleay Basin of eastern Australia. The dataset likely contains geological analysis and depositional models describing its stratigraphic succession, sea-level changes, and faunal assemblages. The data is provided by the Australian Ocean Data Network and was last updated in May 2026.
Use Cases
- Modeling depositional sequences based on described sea-level fall and rise cycles.
- Analyzing facies associations based on the described shift from clastic rocks to limestone.
- Studying paleoecology based on the described alternating dominance of crinoid and bryozoan assemblages.
Strengths
- The description provides a detailed geological context including specific formations (Yessabah Limestone, Parrabel Beds, Warbro Formation).
- The data source is a recognized national network (Australian Ocean Data Network).
- The update timestamp is precise (2026-05-05 00:45:05.388857).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may not be readily machine-readable for analysis.
