Geology and Geochemistry of Tin and Tungsten Deposits in Yukon's McQuesten River Region

Tin and tungsten-bearing veins, breccias and skarns occur in a 60 km long belt trending west from Keno Hill to the Tintina Fault. The dataset likely contains geochemical and mineralogical data for occurrences hosted by mid-Cretaceous intrusions and older metasedimentary rocks. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Identifying mineralogical assemblages based on described vein and skarn types.
• Analyzing geochemical correlations between metals like tungsten, tin, silver, gold, and bismuth.
• Mapping the spatial distribution of tin- and tungsten-dominant occurrences relative to intrusions.
• Using bismuth as a pathfinder for gold in skarns based on the described positive correlation.

Strengths

• Description details a 60 km long belt of occurrences.
• Identifies three distinct stages of skarn mineral formation.
• Provides specific geochemical correlations, such as silver being common in veins with over 50 ppm Sn.

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 Yukon region studied.
