Geology, Carcajou Canyon (southeast), Northwest Territories / [Authors: K.M. Fallas and R.B. MacNaughton]. : M183-1/96-2012E-PDF

"The southeast quadrant of Carcajou Canyon map area (NTS 96-D) lies within the mountainous Canyon Ranges of the eastern Mackenzie Mountains, Northwest Territories. Outcrop is widespread on the higher ridges in the western portion of the map, but decreases to the northeast as ridges become lower and more vegetated toward the Mackenzie Plain. Rock types include siliciclastic, carbonate, and evaporite strata ranging from Neoproterozoic to Paleocene. Proterozoic and Paleozoic strata have been deformed by northwest- to southeast-trending folds and contractional faults associated with Cordilleran deformation. A set of approximately north-trending minor extensional faults are preserved within Proterozoic and Cambrian strata, and were locally reactivated by Cordilleran deformation. Cryogenian igneous activity resulted in the emplacement of gabbroic dykes into strata of the Mackenzie Mountains Supergroup. Two major unconformities represent significant gaps in the local geological record, one between Proterozoic (Cryogenian) and Cambrian strata, and another between Devonian and Cretaceous strata"--Abstract.
