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

The dataset covers geological history from the mid-Ordovician to the Quaternary period. It describes the geology and geochemistry of the 5,030 km² Tantangara and Brindabella 1:100,000 sheet areas in the Lachlan Fold Belt of New South Wales and the Australian Capital Territory. The data was published by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Analyze sedimentary basin evolution based on descriptions of Ordovician to Devonian flysch and shelf sedimentation.
• Model crustal heat flow and metamorphism based on descriptions of Silurian felsic volcanism and granitoid intrusion.
• Assess regional mineral potential based on the mention of known, though small, mineral deposits.
• Reconstruct palaeogeography based on described volcanic arc, marine, and alluvial fan environments from the Ordovician to Devonian.

Strengths

• Covers a defined area of 5,030 square kilometers.
• Provides a detailed geological history spanning from the mid-Ordovician to the Quaternary.
• Includes descriptions of multiple rock types and geological processes, such as flysch sedimentation, volcanic activity, and granitoid intrusion.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific mapped sheet areas.
