Geology And Geochemistry Of The Tantangara And Brindabella Regions

Geological and geochemical data covers a 5,030 km² area within the Lachlan Fold Belt of New South Wales and the Australian Capital Territory. The Australian Ocean Data Network compiled this information detailing rock formations, sedimentary history, volcanic activity, and mineral deposits. The dataset was last updated in April 2026.

Use Cases

• Analyze the distribution of Ordovician to Devonian sedimentary facies, such as flysch and shelf deposits, to model paleogeographic environments.
• Map the spatial extent of Silurian S-type and I-type felsic volcanics and comagmatic granitoids to understand crustal heat flow and anatectic processes.
• Correlate known small mineral deposit locations with specific host rock units and structural features for regional prospectivity analysis.
• Study the sequence of Tertiary uplift events and associated Miocene lacustrine sediments to reconstruct recent tectonic history.
• Model Quaternary landform processes by examining the distribution of colluvium on mountain slopes and alluvium along stream courses.

Strengths

• Covers a defined 5,030 square kilometer mapping area.
• Provides detailed stratigraphic and tectonic history spanning from the Ordovician to the Quaternary period.

Limitations

• Known mineral deposits are described as small and mostly uneconomic, limiting direct resource applications.
• Primary data formats are PDF and HTML, which may require extraction for quantitative spatial analysis.
• Specific sample sizes, analytical measurements, and row/column counts for underlying data are not provided.
