Arrinthrunga Formation: Upper Cambrian Carbonate Sequence in the Georgina Basin, Australia

The Arrinthrunga Formation dataset from the Australian Ocean Data Network describes a complex Upper Cambrian carbonate and mixed carbonate-siliciclastic sequence deposited in an extensive epeiric sea in central Australia. The data likely contains geological observations on lithologies, evaporites, and algal bioherms from the Georgina Basin. The dataset was last updated on 2026-06-27.

Use Cases

• Modeling ancient carbonate platform depositional environments based on described lithological sequences.
• Analyzing the influence of algal mats and bioherms on sediment distribution as described in the formation history.
• Studying the impact of sea-level change and emergence on evaporite formation in shallow marine settings.
• Reconstructing paleogeography and facies belts for the Upper Cambrian in the Georgina Basin.

Strengths

• Dataset is hosted by the authoritative Australian Ocean Data Network.
• Description provides a detailed geological history of the formation's depositional environments.

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 solely on the Georgina Basin.
