Upper Cambrian to Lower Ordovician data on the Ninmaroo Formation, an epeiric carbonate sequence in Australia's Georgina Basin. The dataset describes lithofacies including ooid, peloid, skeletal, and dolostone units, detailing sedimentation in a shallow epicontinental sea under varying salinity and evaporitic conditions. It was published by Geoscience Australia Data and last updated on 2026-03-25.
Use Cases
- Modeling ancient shallow marine environments based on described lithofacies patterns.
- Analyzing cyclic sedimentation patterns likely caused by repeated storm shoaling.
- Studying the impact of salinity and evaporitic conditions on skeletal and non-skeletal carbonate production.
- Reconstructing regressive depositional sequences and shelf progradation from lithofacies data.
Strengths
- Detailed geological description of multiple carbonate lithofacies (ooid, peloid, skeletal, dolostone).
- Specific temporal coverage of the Upper Cambrian to Lower Ordovician period.
- Clear spatial context within the Georgina Basin of Australia.
- Last updated date is provided (2026-03-25).
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is provided in PDF and HTML formats, which may require extraction for computational analysis.
