공공데이터포털
The Joe Mountain map area, northeast of Whitehorse, is underlain by folded, Upper Triassic and Jurassic sedimentary and volcanic strata of the Whitehorse Trough which are intruded by north-trending Cretaceous plutons. Volcanic rocks previously mapped as ""Volcanics of uncertain age"" and Hutshi Group are Triassic in age and comprise three mappable units dominated by thick accumulations of basaltic and andesitic, aphyric pillowed volcanics. The volcanics, and associated sedimentary rocks dominate the eastern part of the map area whereas a thick carbonate assemblage dominates the Upper Triassic stratigraphy in the western part of the map area. The east-west transition represents either a sharp facies change across the map area or a structural juxtaposition. Numerous through-going, north-trending faults which cut the region may originate from motion along the interpreted Lake Laberge Fault Zone which underlies the Yukon River/Lake Laberge valley. Potential mineral deposits in this map area include copper (gold-molybdenum-tungsten) skarns and gold-bearing quartz veins. Regional silt geochemistry indicates that the distribution of the Triassic volcanic suites is spatially coincident with regionally extensive, gold-in-silt anomalies. The source of these anomalies is uncertain and provide for intriguing prospecting targets.
