Permian Yessabah Limestone Sequence Analysis for the Manning-Macleay Basin

Geoscience Australia Data provides a geological analysis of the Permian Yessabah Limestone formation in eastern Australia. The dataset describes the depositional sequence, facies associations, and dominant faunal assemblages of crinoids and bryozoans within a thick crinoidal limestone unit. The record was last updated on 2026-04-20.

Use Cases

• Modeling sequence stratigraphy based on described lowstand, transgressive, and highstand systems tracts.
• Analyzing paleoenvironmental conditions based on the described shallow-marine high-energy setting.
• Studying faunal succession patterns based on the alternating dominance of crinoid and bryozoan assemblages.

Strengths

• Analysis is grounded in a specific, well-defined geological formation (Permian Yessabah Limestone).
• Description provides a detailed conceptual model of depositional sequences and facies changes.
• Record is associated with an authoritative government organization, Geoscience Australia Data.

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/HTML formats, which may require extraction for computational analysis.
