Geology, Inuvik, Northwest Territories . : M183-1/178-2014E-PDF
"The Inuvik map area, NTS 107-B/7 is located in the Northwest Territories on the southeastern edge of the Mackenzie Delta. The western and eastern portions of the map area are underlain by Quaternary fluvial and fluvial fan deposits, and the north central area by hummocky moraine and lacustrine deposits. The south central area is underlain by poorly exposed Cretaceous strata, and fair to poorly exposed Proterozoic and Paleozoic strata. The uplift may be part of an earlier Paleozoic arch. But it presently is part of the Mesozoic Tuk Horst (Wielens, 1992), which centers the Eskimo Lakes Arch. The horst features a complex subcrop of Paleozoic and Proterozoic quartzite, argillite, shale, dolostones and locally volcanics, beneath a pre-Mesozoic unconformity. All strata are openly folded on a scale of tens to hundreds of meters and cut by normal faults. Normal faulting likely has a complex history but is as young as Cretaceous"--Abstract.
