Permian Yessabah Limestone Sequence Analysis, Manning-Macleay Basin

Sequence analysis of the Permian Yessabah Limestone describes a thick crinoidal unit deposited during a major sea-level transgression in northeastern New South Wales. The dataset, hosted by the Australian Ocean Data Network, likely contains geological models and analysis of depositional systems tracts. Last updated metadata indicates a future date of 2026-06-16.

Use Cases

• Modeling sea-level change impacts on sedimentary facies based on described systems tracts.
• Analyzing the distribution of crinoid and bryozoan assemblages based on alternating dominance patterns.
• Reconstructing depositional environments in the Manning-Macleay Basin based on described shallow-marine high-energy settings.

Strengths

• Describes a specific geological formation with a detailed stratigraphic context.
• Metadata indicates association with the authoritative Australian Ocean Data Network.
• The description provides a clear sequence of depositional events and environmental changes.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
