Late Proterozoic to Mississippian strata underlie the West Lake map area (105N/9) in the Hess Mountains of east-central Yukon. The dataset describes three fault-bounded structural blocks containing tectonically thickened Selwyn Basin strata, including Hyland, Road River, and Earn groups. It was published by the Government of Yukon and last updated in April 2026.
Use Cases
- Map structural geology based on fault-bounded blocks and tectonic thickening described.
- Identify potential mineral exploration targets based on silver-bearing quartz veins and stream sediment anomalies.
- Analyze stratigraphic relationships based on descriptions of unconformities and thrust faults.
- Model geological formations based on the distribution of Hyland, Road River, and Earn groups.
Strengths
- Describes specific geological formations (Hyland, Road River, Earn groups) and structural features (West Lake Fault, Wilson Range Fault).
- Identifies a mineral occurrence (Plata) and associated stream sediment anomalies (Ag, Zn, Pb).
- Provides a detailed spatial context for the West Lake map area (105N/9) in the Hess Mountains.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified despite the 2026 update date.
