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

The Australian Ocean Data Network provides geological data for the Tantangara and Brindabella 1:100,000 Sheet areas, covering 5030 km² in New South Wales and the Australian Capital Territory. The dataset describes the geological history from the mid-Ordovician to the Quaternary, including sedimentation, volcanism, deformation, and metamorphism. It was last updated on 2026-06-05.

Use Cases

• Model regional geological evolution based on described stratigraphic sequences and deformation events.
• Assess mineral exploration potential based on mentions of volcanic arcs, granitoid intrusions, and known mineral deposits.
• Study paleoenvironmental changes based on described transitions from marine to fluviatile sedimentation.
• Correlate geological units across the region based on the detailed chronological framework provided.

Strengths

• Covers a defined area of 5030 km² at a 1:100,000 mapping scale.
• Provides a detailed chronological narrative spanning from the Ordovician to the Quaternary.
• Describes specific geological features including volcanic arcs, granitoid suites, and deformation events.

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.
