Permian Yessabah Limestone Sequence Analysis and Depositional Models

The Permian Yessabah Limestone formation in the Manning-Macleay Basin of eastern Australia is described. The dataset, hosted by the Australian Ocean Data Network, includes analysis of its depositional sequence within a major sea-level cycle from the Carboniferous to the Permian. It details the formation's crinoidal and bryozoan faunal assemblages and its relationship to surrounding clastic units.

Use Cases

• Modeling shallow-marine depositional environments based on the described high-energy crinoidal limestone facies.
• Analyzing sea-level change impacts on sedimentary systems based on the described lowstand, transgressive, and highstand systems tracts.
• Studying faunal succession and dominance patterns based on the alternating crinoid and bryozoan assemblages mentioned.
• Correlating stratigraphic units based on the described disconformable contact and facies associations.

Strengths

• Provides a detailed geological narrative covering a complete sea-level cycle from the Carboniferous to the Permian.
• Focuses on a specific, well-defined geological formation (Yessabah Limestone) within a known basin (Manning-Macleay).
• Hosted by an authoritative organization, the Australian Ocean Data Network.

Limitations

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