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

A geological report from the Australian Ocean Data Network describes the Proterozoic and Palaeozoic rock units of the Granites-Tanami region in Western Australia and Northern Territory. The data correlates these formations with similar rocks across northwestern and central Australia, including the Kimberley and Amadeus Basin regions. The report was last updated on 2026-06 23.

Use Cases

• Correlating stratigraphic units like the Tanami Complex with the Halls Creek Group based on regional geological descriptions.
• Analyzing the tectonic history of the Birrindudu Basin based on described phases of activity from 1960 m.y. to early Carboniferous.
• Modeling the paleogeographic interconnection of basins based on correlations such as the Redcliff Pound Group with the Heavitree Quartzite.

Strengths

• Includes specific geological age ranges, such as granites dated 1820-1710 m.y. and the Birrindudu Group at about 1560 m.y.
• Provides detailed interregional correlations with named geological units in five surrounding areas.
• Identifies five major phases of tectonic activity with defined age brackets.

Limitations

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