Geological Compilation Maps of the Northern Stewart River Area, Klondike and Sixtymile Districts (115N/15, 16, 115O/13, 14 and Parts of 115 O/15, 16)

Geological Compilation Maps of the Northern Stewart River Area, Klondike and Sixtymile Districts (115N/15, 16, 115O/13, 14 and Parts of 115 O/15, 16) This set of maps represents a geological compilation of the northern part of the Stewart River map area, southwest of the Tintina Fault Zone. This report includes six 1:50 000-scale bedrock geology maps which cover NTS map sheets 115 N/15 (Crag Mountain), 115 N/16 (Enchantment Creek), 115 O/13 (Garner Creek), 115 O/14 (Grand Forks), 115 O/15 (Flat Creek) and 115 O/16 (Medrick Creek). The maps are based mainly on geological mapping carried out by the author on behalf of Archer, Cathro and Associates (1981), Ltd. In 1983-84 and the Geological Survey of Canada between 1986 and 1991. Final filed checking, map compilation and synthesis was done in 1995-96 with support from the Canada/Yukon Geoscience Office. Published maps by Cockfield (1927), Bostock (1942), Tempelman-Kluit (1974), and Debicki (1983, 1984), as well as original field notes from 1935-36 by H.S. Bostock and a number of unpublished mineral assessment reports, were used to supplement the author's observations. All available isotopic ages from the area are also shown. The lithostratigraphic legend used for these maps was developed for both this series of maps and adjoining portions of southwestern Dawson map area (116 B,C) to the north (Mortensen, 1988). Note that not all of the units included in the legend are necessarily present in the northern Stewart River map area. 2021-11-02 Government of Yukon geology@gov.yk.ca Science and TechnologyYukon Geological Survey Packageother https://data.geology.gov.yk.ca/reference/42888 Original metadata (https://open.yukon.ca)HTML https://open.yukon.ca/data/datasets/geological-compilation-maps-northern-stewart-river-area-klondike-and-sixtymile
