Geological Constraints on Metal Veins in Mount Nansen, Yukon

Geological and geochronological data describe epithermal vein and porphyry-related gold-silver deposits in the Mount Nansen area of Yukon. The dataset includes U-Pb zircon and titanite ages for intrusive rocks and mineralization events, published by the Government of Yukon. It was last updated on April 17, 2026.

Use Cases

• Correlating mineralization events with intrusive rock ages based on U-Pb dating results
• Mapping the spatial distribution of vein systems based on the described Mount Nansen Trend
• Analyzing the relationship between felsic magmatism and metal deposits based on the proximal relationship described
• Comparing mid-Cretaceous and Late Cretaceous mineralization periods in the Dawson Range based on previous studies cited

Strengths

• Includes specific U-Pb zircon ages with error margins, such as 108.3 ± 0.7 Ma for the Dickson stock
• Provides geological context linking mineralization to specific rock units like the Yukon-Tanana Terrane and Big Creek Batholith

Limitations

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