Geology, Norman Wells (southwest), Northwest Territories / [by] K.M. Fallas ... [et al.]. : M183-1/101-2012E-PDF
"The southwest quadrant of Norman Wells map area (NTS 96-E) covers parts of the Franklin Mountains, Mackenzie Plain, and Mackenzie Mountains, Northwest Territories. The area varies from low-lying forested plain to alpine mountainous terrain, with bedrock exposures concentrated in the mountains on either side of the Mackenzie River. The geological interpretation in poorly exposed portions of the Mackenzie Plain has been enhanced by examination of public-domain seismic-reflection lines, archived with the National Energy Board. Cordilleran deformation from the southwest has uplifted Proterozoic and/or Paleozoic strata along reverse or thrust faults, and anticlinal folds in both the Mackenzie and Franklin mountains. The intervening Mackenzie Plain is dominated by folded and faulted Devonian and Cretaceous siliciclastic strata that have largely been planed off by glacial activity. The lack of surface exposure of Proterozoic strata in the Norman Range indicates this interval is not involved in Franklin Mountain structures, in contrast to the Mackenzie Mountains. An unconformity at the base of Upper Cretaceous strata cuts more deeply into underlying strata to the northeast, a reflection of uplift along the Keele Arch before deposition of the Slater River Formation. Exploration by petroleum companies in the area has typically targeted potential reservoirs in buried Devonian strata"--Abstract.
