Ninmaroo Formation Sedimentary Data for Upper Cambrian-Lower Ordovician Period

Upper Cambrian-Lower Ordovician sedimentary data from the Ninmaroo Formation in the Georgina Basin, describing lithofacies and depositional environments. The dataset comprises descriptions of ooid, peloid, skeletal, and dolostone lithofacies, along with terrigenous sandstones. It was published by the Australian Ocean Data Network and last updated on 2026-04-10.

Use Cases

• Modeling ancient epeiric carbonate sedimentation patterns based on described lithofacies.
• Analyzing paleoenvironmental conditions based on described normal marine, saline, and evaporitic settings.
• Studying cyclic sedimentation and regressive sequences based on described depositional patterns.
• Investigating diagenetic processes based on the described late diagenetic crystalline dolostone lithofacies.

Strengths

• Detailed description of multiple carbonate lithofacies including ooid, peloid, and skeletal sands.
• Specific temporal coverage for the Upper Cambrian-Lower Ordovician period.
• Clear spatial context within the Georgina Basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided as PDF/HTML documents, not in a structured tabular format.
