Geology And Geochemistry Of The Tantangara And Brindabella Sheet Areas

The Tantangara and Brindabella 1:100,000 Sheet areas cover 5,030 square kilometers in the Lachlan Fold Belt of New South Wales and the Australian Capital Territory. It details the geological history from the mid-Ordovician to the Quaternary, including sedimentation, volcanism, and deformation events. The dataset was published by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Analyze the spatial distribution of Ordovician tholeiitic basalts and shoshonites to model volcanic arc evolution.
• Map the extent of Silurian S-type and I-type granitoids and felsic volcanics to study crustal heat flow and anatexis.
• Correlate Devonian fluviatile sequences of conglomerate, sandstone, and shale to understand sedimentary cycles and basin termination.
• Study the described mineral deposits, though noted as small and uneconomic, within the context of regional geology.
• Examine the described Tertiary uplift events and Miocene lacustrine sediments to model recent geomorphological development.

Strengths

• Covers a defined area of 5,030 square kilometers at a 1:100,000 scale.
• Provides a detailed chronological narrative spanning from the mid-Ordovician to the Quaternary period.

Limitations

• Primary data format is PDF/HTML reports, not structured tabular data for direct analysis.
• No quantitative sample data, column definitions, or row counts are provided.
• Known mineral deposits are described as small and mostly uneconomic, limiting resource assessment value.
