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. The dataset describes the geological history, including sedimentation from the mid-Ordovician to the Devonian, volcanic activity, deformation events, and Quaternary deposits. It is provided by Geoscience Australia Data and was last updated in May 2026.

Use Cases

• Map regional geological units based on described stratigraphy and rock types.
• Analyze volcanic arc evolution based on descriptions of tholeiitic basalts and shoshonites.
• Study sedimentary basin development based on the described flysch, shelf, and fluviatile sequences.
• Model crustal heat flow and metamorphism based on descriptions of anatectic granitoids and greenschist facies metamorphism.
• Assess mineral potential based on the mention of known, though small, mineral deposits.

Strengths

• Covers a defined area of 5,030 square kilometers.
• Provides a detailed geological history spanning from the Ordovician to the Quaternary.
• Sourced from Geoscience Australia Data, a national geological survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats are PDF and HTML, which may require manual data extraction for analysis.
