Tantangara and Brindabella Geology and Geochemistry, 1:100,000 Scale

Geoscience Australia Data provides a geological and geochemical dataset covering 5,030 km² in the Tantangara and Brindabella 1:100,000 sheet areas of New South Wales and the Australian Capital Territory. The data describes the region's complex geological history, including sedimentation from the mid-Ordovician to the Middle Devonian, multiple volcanic and intrusive events, and subsequent deformation. The dataset was last updated on 2026-03-25.

Use Cases

• Modeling tectonic evolution based on described sequences of sedimentation, volcanism, and deformation.
• Assessing mineral potential based on described rock types and known small mineral deposits.
• Correlating regional stratigraphy using detailed descriptions of Ordovician to Devonian geological units.
• Studying metamorphic processes based on descriptions of upper greenschist facies metamorphism and anatectic products.

Strengths

• Covers a defined area of 5,030 square kilometers.
• Provides a detailed, multi-event geological history spanning from the Ordovician to the Quaternary.
• Includes descriptions of both geochemistry (e.g., tholeiitic basalts, shoshonites) and structural geology.

Limitations

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