A bedrock geology map of the southern Nash Creek area in central Yukon, covering parts of NTS 106D/2, 3, 6 and 7. The map was produced by the Government of Yukon and details stratigraphic units, thrust faults, and gabbro sills. It was last updated on April 17, 2026.
Use Cases
- Identify stratigraphic units and formations based on detailed geological descriptions.
- Analyze regional-scale thrust fault structures like the Dawson and Robert Service thrusts.
- Locate areas with potential Au and polymetallic mineral deposits hosted by specific formations.
- Study the distribution and age of gabbro sills within the mapped formations.
- Analyze structural features such as foliation and fold trends described in the area.
Strengths
- Mapping conducted at a detailed 1:50,000 scale.
- Describes specific geological formations (Hyland, Earn, Tsichu Groups) and their constituent units.
- Identifies regional-scale structural features like thrust faults and folds.
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 a single regional mapping project.
