Description
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).
