Arrinthrunga Formation: Upper Cambrian Carbonate Sequence in the Georgina Basin

Upper Cambrian sedimentary data from the Arrinthrunga Formation in central Australia's Georgina Basin. The dataset, published by the Australian Ocean Data Network, describes a complex carbonate and mixed carbonate-siliciclastic sequence deposited in a shallow, hypersaline epeiric sea. It details lithologies, depositional environments, and paleogeographic changes, with the record last updated on 2026-06-05.

Use Cases

• Modeling ancient shallow-marine depositional environments based on described carbonate lithologies and evaporite sequences.
• Analyzing paleogeographic changes and sea-level fluctuations based on described transgression and regression events.
• Studying the role of filamentous algae in carbonate production and bioherm formation in hypersaline conditions.

Strengths

• Detailed geological description of a specific Upper Cambrian formation with a complex depositional history.
• Focus on a well-defined geographic region (Georgina Basin, central Australia) and temporal period (Upper Cambrian).
• Last updated date is provided (2026-06-05).

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/temporal bias inherent to data_gov_au.
