Proterozoic and Palaeozoic Rock Formations in the Granites-Tanami Region, Australia

Geoscience Australia Data published a geological report on the Granites-Tanami region, linking Proterozoic areas of northwestern and central Australia. The report describes two main tectonic units, five major tectonic phases from 1960 million years ago to the early Carboniferous, and correlations with other Australian geological regions. The data was last updated on 2026-03-25.

Use Cases

• Correlating regional stratigraphy based on described rock units like the Tanami Complex and Birrindudu Group.
• Modeling tectonic evolution based on the five described phases of tectonic activity.
• Studying basin interconnection based on the correlation between the Redcliff Pound Group and Amadeus Basin units.

Strengths

• Provides specific geological time ranges, such as granites aged 1820-1710 million years and tectonic phases from 1960 million years ago.
• Includes detailed interregional correlations with five other Australian geological regions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
