Online_Linkage: Description: Abstract: The map area lies in the central part of the Boothia Uplift, a linear, positive structural feature extending northward more than 900 km from southern Boothia Peninsula through Somerset Island to the central Arctic Archipelago. The southern two-thirds of the uplift comprises a crystalline core (a salient of the Precambrian Shield) and flanking unmetamorphosed, Proterozoic to Devonian sedimentary strata. The salient is bordered on the west (Prince of Wales Island) by a Silurian-Devonian clastic wedge. Uplift largely occurred along steeply east-dipping thrust faults during the Siluro-Devonian, the movement possibly being related to Caledonian orogeny far to the east (Okulitch et al., 1986). The crystalline core between 71° and 74°N, some 80 km wide and consisting of high-grade metamorphic rocks of the Churchill Structural Province, was the focus of the mapping project. Purpose: Supplemental_Information: Data set is in English. Magnetic declination stated in degrees and minutes. Annual change stated in minutes. Magnetic declination at NW corner of map: 29°29'W, changing 36.3'E annually. Magnetic declination at SW corner of map: 17°3'W, changing 7.5'E annually. Magnetic declination at NE corner of map: 22°25'W, changing 18.7'E annually. Magnetic declination at SE corner of map: 23°13'W, changing 21.7'E annually. Magnetic declination at center of map: 23°13'W, changing 21.7'E annually. Proximity of the North Magnetic Pole causes the compass to be useless in this area.
