Geology and Geochemistry of the Tantangara and Brindabella 1:100,000 Sheet Areas

The Tantangara and Brindabella 1:100,000 Sheet areas cover 5030 km² in New South Wales and the Australian Capital Territory, within the Lachlan Fold Belt. The dataset describes the geological history, including sedimentation, volcanism, and deformation events from the Ordovician through the Quaternary. It was published by the Australian Ocean Data Network and last updated on April 10, 2026.

Use Cases

• Modeling regional geological history based on described sedimentation and volcanic events.
• Analyzing the distribution and genesis of mineral deposits based on described lithology and metamorphic grades.
• Studying crustal heat flow and metamorphism based on descriptions of Silurian anatectic processes.
• Mapping Quaternary landform processes based on descriptions of colluvium and alluvium deposition.

Strengths

• Covers a defined area of 5030 km² with precise latitude and longitude boundaries.
• Provides a detailed, multi-period geological history spanning from the Ordovician to the Quaternary.
• Describes specific rock types and processes, such as tholeiitic basalts, ignimbrites, and greenschist facies metamorphism.

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 as PDF/HTML reports, which may require extraction for computational analysis.
