The Proterozoic and Palaeozoic rocks of The Granites-Tanami region, Western Australia and

The Granites-Tanami region links Proterozoic areas of northwestern and central Australia. The dataset describes two main tectonic units: the Granites-Tanami Block and the Birrindudu Basin, with rock formations dated from the Lower Proterozoic (1960 m.y.) to the early Carboniferous. It is provided by the Australian Ocean Data Network and was last updated in 2026.

Use Cases

• Correlating rock formations based on described stratigraphic units like the Tanami Complex and Redcliff Pound Group.
• Analyzing tectonic evolution based on the five major phases of tectonic activity mentioned.
• Studying basin interconnectivity based on correlations between the Birrindudu and Amadeus Basins.

Strengths

• Includes specific geological time ranges, such as granites dated 1820-1710 m.y. and the Birrindudu Group dated about 1560 m.y.
• Provides interregional correlations with named geological regions like the Kimberley region and Amadeus Basin.

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 on a specific Australian region.
