"The southeast quadrant of Norman Wells map area (NTS 96-E) covers parts of the Franklin Mountains and Mackenzie Plain, Northwest Territories. The area varies from low-lying forested plain to alpine mountainous terrain along the Norman Range, with bedrock exposures concentrated along the mountain ridges, and stream or lake outcrops. 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 triggered uplift of Cambrian and younger strata along reverse or thrust faults in the Franklin Mountains. The variation in trend of significant faults is believed to be due to the reactivation of older normal faults. To the southwest of the Norman Range, the Mackenzie Plain is dominated by folded Devonian and Cretaceous siliciclastic strata that have largely been planed off by glacial activity. The presence of the Saline River Formation, an evaporitic unit, in the hanging wall of larger faults suggests its involvement as a local detachment surface. An unconformity at the base of Upper Cretaceous strata cuts more deeply into underlying Lower Cretaceous and Devonian strata to the northeast, a reflection of uplift along the Keele Arch before deposition of the Slater River Formation. This map area includes the Norman Wells oilfield, a field that has been active for many decades, producing oil from the Kee Scarp Member of the Ramparts Formation, a limestone reef encased in shale"--Abstract.
