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 approximately 1960 to 1000 million years ago, overlain by Early Cambrian volcanics and younger Palaeozoic sediments. It was published by Geoscience Australia Data and was last updated on 2026-04-30.
Use Cases
- Correlating regional stratigraphy based on described rock units and tectonic phases.
- Studying the tectonic evolution of the Australian continent based on the five major phases of activity described.
- Modeling ancient basin interconnections based on correlations between the Birrindudu and Amadeus Basins.
Strengths
- Provides specific geological time ranges, such as granites dated 1820-1710 m.y. and the Birrindudu Group dated about 1560 m.y.
- Includes detailed interregional correlations with named geological units in surrounding Australian regions.
- Describes a clear geological framework with two main tectonic units and five major phases of tectonic activity.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is provided in PDF and HTML formats, which may require extraction for computational analysis.
