Geological Mapping of the Robert Service Thrust in Yukon's Mayo Area

Revision geological mapping has shown that the Robert Service Thrust is imbricated and isoclinally folded in the Mayo map area. The Government of Yukon produced this report, which was last updated on April 17, 2026. It describes the occurrence of vuggy meta-diorite, geochemically anomalous headwater creeks, and downstream placer mining on Fork Plateau.

Use Cases

• Analyze structural geology based on descriptions of imbricated and isoclinally folded thrust faults.
• Identify potential mineral exploration targets based on the occurrence of vuggy meta-diorite and geochemically anomalous creeks.
• Assess placer mining potential downstream based on the described geological features.
• Interpret antiformal windows in the hanging wall based on descriptions of highly deformed Keno Hill quartzite and meta-diorite.

Strengths

• Report is authored by the authoritative Government of Yukon.
• Last updated on April 17, 2026, indicating recent maintenance.
• Focuses on a specific geological structure (Robert Service Thrust) and region (Mayo map area, Fork Plateau).

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 Yukon region.
