The Ninmaroo Formation dataset describes epeiric carbonate sedimentation from the Upper Cambrian to Lower Ordovician period in the Georgina Basin. It comprises lithofacies data including ooid, peloid, skeletal, and dolostone types, detailing depositional environments from shallow marine to evaporitic conditions. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-27.
Use Cases
- Modeling ancient shallow marine depositional environments based on described lithofacies patterns.
- Analyzing cyclic sedimentation patterns likely driven by storm shoaling events.
- Reconstructing paleogeographic evolution based on the two described regressive depositional sequences.
- Studying the impact of salinity on carbonate production and faunal restriction in described environments.
Strengths
- Detailed geological description of multiple carbonate lithofacies (ooid, peloid, skeletal, dolostone).
- Clear temporal coverage specified as Upper Cambrian to Lower Ordovician.
- Spatial context is provided for the Georgina Basin.
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 presented in HTML and PDF formats, which may limit machine-readability.
