Proterozoic and Palaeozoic Rocks of the Granites-Tanami Region, Western Australia

The Granites-Tanami region links the Proterozoic areas of northwestern and central Australia. It contains two main tectonic units with rocks ranging from Lower Proterozoic (1960 million years) to early Carboniferous, correlated with five other Australian geological regions. The dataset is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Correlating stratigraphic units based on described rock types and ages.
• Analyzing tectonic evolution based on the five major phases of tectonic activity.
• Modeling basin interconnectivity based on correlations like the Redcliff Pound Group with the Amadeus Basin.
• Mapping regional geology using the described tectonic units and rock formations.

Strengths

• Describes a key geological region linking major Proterozoic areas of Australia.
• Provides specific age ranges for rock units, such as 1820-1710 million-year-old granites.
• Includes interregional correlations with five other defined geological regions.

Limitations

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