The Permian Yessabah Limestone dataset documents a thick crinoidal limestone unit from the Manning-Macleay Basin in eastern Australia. It was created by Geoscience Australia Data and last updated on 2026-03-25. The data describes depositional models, sea-level changes, and alternating faunal assemblages of crinoids and bryozoa within a transgressive systems tract.
Use Cases
- Modeling sequence stratigraphy based on described systems tracts (lowstand, transgressive, highstand).
- Analyzing paleoenvironmental changes based on the transition from clastic to carbonate to turbidite facies.
- Studying faunal succession patterns based on alternating crinoid-rich and bryozoan-rich limestone units.
Strengths
- Data originates from Geoscience Australia Data, a national geological survey.
- The description provides a detailed geological context for the formation's depositional history.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is provided in PDF/HTML formats, which may require extraction for computational analysis.
