| Abstract | The area includes Archean rocks of Slave craton and Paleoproterozoic rocks of Wopmay orogen. Both groups of rocks were deformed at 1.882 Ga during the Calderian orogeny (Hildebrand et al., 2010a). Rocks
of Slave craton and its cover occur in the eastern part of the map area within and east of the medial zone (Hildebrand et al., 1990), where they form a crustal duplex structurally beneath rocks of Hottah terrane, which comprises metasedimentary rocks
of Akaitcho group (Easton, 1982) sitting unconformably upon Bent gneiss (Hildebrand et al., 1991), and intruded by plutons of Hepburn batholith (Lalonde, 1986). Sitting unconformably atop, and intruding, the collapsed collision zone, are magmatic and
sedimentary rocks of the 1.875-1.843 Ga Great Bear magmatic zone (Hoffman and McGlynn, 1977; Hildebrand et al., 1987b, 2010b). Rocks of the area were folded about northwest to northerly trending axes and cut by a swarm of strike-slip faults.

| Summary | (Plain Language Summary, not published)
This geological map compiles the rock types and the structural attributes of the Calder River map area (NTS 86F; 1:25000 scale) to the SE of Great Bear
Lake, Northwest Territories. The area falls largely within the Wek'èezhìi management region reaching across the Sahtu region and the limit of Tliçho Private Land. Mapping was conducted at 1:16,000 to 1:50,000 between 1979 and 1990 by the Department
of Indian and Northern Affairs and the Geological Survey of Canada. Most outcrops of Precambrian volcanic and sedimentary rocks were mapped. In areas of slightly younger plutonic igneous rocks, irregularly spaced traverses were made. Hildebrand
(1982; 1984a, b); Hildebrand et al., 1987, 1988, 1990, 1991); and Pelletier (1988) discussed field results. The IOCG-Great Bear project of the Geo-mapping for Energy and Minerals (GEM) Program undertook the recovery of all legacy geological
information and the digitalization and publication of the map. The map is released jointly with the Northwest Territories Geoscience Office. |
