Peliminary observations on the geology of the Anvil Lake area (parts of NTS 105K/11 and 12), central Yukon

The Anvil Lake area consists of mostly contact-metamorphosed siltstone and sandstone having lesser interbedded volcanic and carbonate units that belong to the Early Paleozoic Selwyn basin, thrust northward over the Devono-Mississippian Earn Group and Carboniferous to Triassic formations. These are intruded by the mid-Cretaceous Anvil batholith. The mapped area surrounds the Keg, a disseminated silver-base metal deposit of current interest; new bedrock information will increase the efficiency of exploration of silver bearing veins noted along stratigraphic and structural contacts regionally. It is the first season of an investigation aiming to provide more detailed revision of regional maps, with further paleontology, geochronology, and structural analysis.
