Permian Yessabah Limestone Sequence Analysis, Manning-Macleay Basin, Australia

A geological study of the Permian Yessabah Limestone formation in the Manning-Macleay Basin of eastern Australia. The dataset, provided by the Australian Ocean Data Network, describes the depositional sequence, facies associations, and dominant faunal assemblages of crinoids and bryozoa within this thick crinoidal limestone unit. It was last updated on 2026-04-10.

Use Cases

• Modeling sea-level change impacts on sedimentary facies based on the described lowstand, transgressive, and highstand systems tracts.
• Analyzing the alternation of dominant faunal assemblages based on the described cycles of crinoid-rich and bryozoan-rich limestone units.
• Studying basin evolution and sequence stratigraphy based on the described relationships between the Yessabah Limestone, underlying Parrabel Beds, and overlying Warbro Formation.

Strengths

• The description provides a detailed geological narrative of the formation's depositional history.
• The dataset is hosted by the authoritative Australian Ocean Data Network.
• A specific last update date of 2026-04-10 is provided.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file formats are PDF and HTML, which may require manual extraction for computational analysis.
