The Australian Ocean Data Network hosts data on the Ninmaroo Formation, an Upper Cambrian to Lower Ordovician epeiric carbonate sequence in the Georgina Basin. The description details lithofacies including ooid, peloid, skeletal, and dolostone units, deposited in cyclic, shallow marine environments under varying salinity. The dataset was last updated on 2026-06-23.
Use Cases
- Modeling ancient shallow marine depositional environments based on described lithofacies patterns.
- Analyzing cyclic sedimentation patterns linked to storm shoaling events mentioned in the description.
- Studying the impact of salinity on carbonate skeletal production and faunal restriction as described.
- Reconstructing regressive depositional sequences from the described barrier progradation and offlap events.
Strengths
- The description provides a detailed geological context including specific lithofacies types (ooid, peloid, dolostone).
- The temporal range (Upper Cambrian-Lower Ordovician) and geographic location (Georgina Basin) are explicitly stated.
- The depositional model is described in detail, including environmental conditions and cyclic sedimentation drivers.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au, focusing on a single Australian basin.
