Geology of the Canberra 1:100,000 Sheet Area in New South Wales and ACT

The Canberra 1:100,000 Geological Sheet covers approximately 2500 km² of hilly, upland terrain in the Australian Capital Territory and southeastern New South Wales. The bedrock comprises Ordovician to Silurian sediments and acid volcanics which have been invaded by several generations of Silurian intrusions. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-05.

Use Cases

• Map bedrock geology based on the described Ordovician to Silurian sediments and volcanics.
• Analyze geological structures and intrusions based on the described multiple generations of Silurian intrusions.
• Conduct regional geological studies based on the 1:100,000 scale mapping of the 2500 km² area.

Strengths

• Covers a defined area of approximately 2500 km².
• Describes specific geological time periods (Ordovician to Silurian) and rock types (sediments, acid volcanics, intrusions).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
