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

5030 km² of geological mapping in the southern Lachlan Fold Belt, covering parts of New South Wales and the Australian Capital Territory. The data details a complex geological history from the mid-Ordovician to the Quaternary, including sedimentation, volcanic activity, and deformation events. It was published by the Australian Ocean Data Network and includes information on known mineral deposits.

Use Cases

• Regional geological mapping and stratigraphic correlation based on described rock units and ages.
• Studying the evolution of volcanic arcs and magmatic systems based on descriptions of tholeiitic basalts, shoshonites, and felsic volcanics.
• Analyzing sedimentary basin development and deformation history from the described flysch, shelf, and fluviatile sequences.
• Assessing mineral potential by referencing the described, though small, mineral deposits.

Strengths

• Covers a defined 5030 km² area with precise latitude/longitude bounds.
• Provides a detailed, multi-period geological history from the Ordovician to the Quaternary.
• Includes descriptions of various rock types, geological processes, and mineral occurrences.

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.
