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

5,030 km² of geological mapping and geochemical data from the southern Lachlan Fold Belt in New South Wales and the Australian Capital Territory. The description details a complex geological history spanning from the mid-Ordovician to the Quaternary, including sedimentation, volcanism, and deformation events. This dataset is published by Geoscience Australia and was last updated in April 2026.

Use Cases

• Model regional geological evolution based on described stratigraphy and deformation events.
• Analyze the distribution of mineral deposits based on the described volcanic and intrusive rock types.
• Study paleoenvironmental changes from the described transitions between marine, shelf, and fluviatile sedimentation.
• Correlate geochemical signatures with described S-type and I-type magmatic suites.

Strengths

• Covers a specific 5,030 km² area with a detailed geological history.
• Includes data on multiple geological processes like sedimentation, volcanism, and metamorphism.
• Published by the authoritative national geological survey, Geoscience Australia.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite the 2026 update date.
