Preliminary geology of Rose Mountain, Anvil District, central Yukon (105 K/5)
A 2000 m thick succession of six metasedimentary and metavolcanic units ranging in age from Ordovician through Permian strikes northwest and dips moderately to the southwest in the Rose Mountain area (105K/05). Units 3-6 have conformable contacts exposed and form a continuous succession. Units 1, 2 and 4 are correlated with lower to middle Paleozoic regional stratigraphic units of ancestral North America. Unit 3 consists of pale green argillite with lesser chert pebble conglomerate, sandstone and shale chip breccia interbeds, and is unique to the Rose Mountain area. Unit 5 is bedded chert and is correlated with North American Mount Christie formation. Unit 5 is also similar to chert units in Slide Mountain Terrane. Unit 6 correlates with basalts of the Slide Mountain Terrane. Unit 4 is correlated with Earn Group and contains two stratiform barite horizons. No sulphides are visibly associated with the barite, but the unit is favourable for stratiform base metal mineralization. All units contain one major deformation fabric. This contrasts with structural style immediately to the northeast where two major deformation fabrics occur. The Rose Mountain fabric is correlated with the older deformation fabric present to the northeast.

Preliminary geology north of Mount Mye, Anvil District (105K/6, 105K/7), central Yukon
공공데이터포털
The northeast Anvil area, 15 km north of Mount Mye (NTS 105K/6, 105K/7), is underlain by a conformable Cambrian-Devonian volcanic and sedimentary package with an aggregate thickness of greater than 1600 m. The lowest unit, with an exposed thickness of 120 m, consists of calcareous phyllites of the Cambrian-Ordovician Vangorda formation. Conformably overlying the phyllites is a >900-m-thick Ordovician-Silurian sequence of submarine basalt flows and volcaniclastic sedimentary rocks of the Menzie Creek formation. Volcaniclastic sediments are dominantly coarse, proximal, fragmental breccias with lesser conglomerates, sandstones, and siltstones. Carbonaceous shales with lesser siltstones, limestones, dolostones, and quartzites of the Ordovician-Devonian Road River Group (>450 m) are intercalated with and overlying the basalt flows. The east margin of the map area is a depositional edge of basalt volcanism with only scattered thin flows occurring further to the east. This depositional edge is considered to be a north-trending, west-side-down, Ordovician-Silurian syndepositional, normal fault forming the east margin of a sedimentary sub-basin infilled with volcanic rocks. Hornfelsing on the east margin of the map area indicates a large, shallowly buried, northwest extension of the mid-Cretaceous Orchay Batholith.
