Thrust Faults and Gold Veins in Klondike District, Yukon

Regional-scale thrust faults in Yukon's Klondike District separate lithologic units including Upper Permian Klondike Schist, Paleozoic Finlayson assemblage, and Slide Mountain terrane greenstones. These Jurassic thrust slices contain post-metamorphic compressional structures like recumbent folds and spaced cleavage, with gold-bearing veins confined to the Klondike Schist. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.

Use Cases

• Map thrust fault geometries based on lithologic unit boundaries described.
• Analyze spatial relationships between gold veins and kink-fold axial surfaces.
• Model structural evolution based on described overprinting of thrust fabrics by kink-folding.
• Identify potential mineralization zones based on carbonaceous material concentration along cleavage.

Strengths

• Description details specific lithologic units (Klondike Schist, Finlayson assemblage, Slide Mountain terrane).
• Identifies structural features (thrust slices, recumbent folds, spaced cleavage, kink folds).
• Links geological structures to gold vein emplacement mechanisms.

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 Klondike District.
