Arrinthrunga Formation: Upper Cambrian Carbonate Sedimentology in Central Australia

Upper Cambrian geological data from the Arrinthrunga Formation in the Georgina Basin, central Australia. The dataset, from Geoscience Australia Data, describes a complex carbonate and mixed carbonate-siliciclastic sequence deposited in a shallow, hypersaline epeiric sea. It details sedimentary environments including algal bioherms, peloid shoals, and evaporite pans, with a last update recorded on 2026-04-30.

Use Cases

• Modeling ancient shallow marine depositional environments based on described carbonate lithologies and algal controls.
• Analyzing paleoenvironmental changes from transgression-regression cycles described in the formation's history.
• Studying the formation of evaporite deposits based on the described conditions of high salinity and intermittent emergence.

Strengths

• Detailed geological description of a specific Upper Cambrian formation.
• Spatial coverage is clearly defined as the Georgina Basin in central Australia.
• Last update timestamp is precisely recorded as 2026-04-30 14:43:15.529924.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided in PDF/HTML formats, which may require extraction for computational analysis.
