Ninmaroo Formation Sedimentary Facies and Depositional Sequences

Upper Cambrian-Lower Ordovician sedimentary data from the Ninmaroo Formation in the Georgina Basin. The dataset describes lithofacies including ooid, peloid, skeletal, and dolostone units, deposited in a shallow epicontinental sea under varying salinity and tidal conditions. It was published by Geoscience Australia Data and last updated on 2026-04-30.

Use Cases

• Modeling ancient shallow marine depositional environments based on described lithofacies patterns.
• Analyzing cyclic sedimentation and storm shoaling events mentioned in the description.
• Studying the impact of salinity and evaporitic conditions on carbonate and skeletal production.
• Reconstructing paleogeography and regressive sequences from the described barrier complex and progradation events.

Strengths

• Describes a specific geological formation with a defined time range (Upper Cambrian-Lower Ordovician).
• Includes detailed lithofacies descriptions such as ooid, peloid, and flat-pebble conglomerate.
• Provides a conceptual model of depositional environments and sequences.

Limitations

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