Permian Yessabah Limestone Sequence Analysis, Manning-Macleay Basin

The Permian Yessabah Limestone is a thick crinoidal limestone unit deposited in northeastern New South Wales, Australia. It was deposited as part of a transgressive systems tract in a shallow-marine high-energy environment, following a major sea-level fall at the end of the Carboniferous. The dataset, provided by the Australian Ocean Data Network, includes analysis of depositional models and sequence stratigraphy for this formation.

Use Cases

• Modeling sequence stratigraphy based on described systems tracts (lowstand, transgressive, highstand).
• Analyzing paleoenvironmental conditions based on the described shallow-marine high-energy depositional setting.
• Studying faunal assemblage alternation patterns based on the described cycles of crinoid-rich and bryozoan-rich limestone units.

Strengths

• Description provides a detailed geological narrative of depositional sequence and environmental change.
• Dataset is hosted by the authoritative Australian Ocean Data Network.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
