Geology, Carcajou Canyon (northwest), Northwest Territories / [Authors: K.M. Fallas and R.B. MacNaughton]. : M183-1/94-2012E-PDF
"The northwest quadrant of Carcajou Canyon map area (NTS 96-D) lies within the mountainous Canyon Ranges of the eastern Mackenzie Mountains, Northwest Territories. Well exposed siliciclastic, carbonate, and evaporite strata range from Neoproterozoic to Devonian in the Mackenzie Mountains. Cretaceous shale and sandstone is preserved only beneath the Mackenzie Plain, in the northeast corner of the map. Proterozoic and Paleozoic strata have been deformed by northwest-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 sills and 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.
