The Arrinthrunga Formation in the Georgina Basin of central Australia is a complex Upper Cambrian carbonate and mixed carbonate-siliciclastic sequence. It was deposited in a shallow, extensive, and intermittently emergent epeiric sea under warm, arid conditions, leading to high salinities and local evaporite precipitation. The dataset, hosted by the Australian Ocean Data Network, describes the lithological and environmental evolution of this formation.
Use Cases
- Modeling paleoenvironmental conditions based on described evaporite and algal mat sequences.
- Analyzing carbonate platform evolution from the described cycles of transgression, regression, and shoaling.
- Studying the role of filamentous algae in carbonate production within the described hypersaline lagoon setting.
- Reconstructing depositional facies distribution based on described bioherms, peloid-ooid sands, and quartz-ooid shoals.
Strengths
- The description provides a detailed, process-oriented narrative of the formation's depositional history.
- The dataset is associated with a specific geological formation and basin, providing clear geographic and stratigraphic context.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The data format is HTML/PDF, suggesting the primary data may be textual reports rather than structured tables.
