Nature of the Robert Service Thrust on Fork Plateau and implications for mineral exploration, Mayo map area
Revision geological mapping has shown that the Robert Service Thrust is imbricated and isoclinally folded in Mayo map area. On Fork Plateau, highly deformed Keno Hill quartzite and meta-diorite that occur above the hanging wall Hyland Group are inferred to be antiformal windows resulting from folding of the fault surface. The occurrence of vuggy meta-diorite on Fork Plateau, geochemically anomalous headwater creeks and placer mining downstream, indicates that the Fork Plateau may warrant further exploration.
The Government of Yukon acknowledges that Indigenous Peoples have traditional territories throughout the Yukon and celebrates their role as stewards of the lands and waters and their ongoing connection to this place.
