Bedrock geology, Campbell Lake, Northwest Territories / [authors: M.P. Cecile ... [et al.]].: M183-1/179-2014E-PDF

"The Campbell Lake map area, NTS 107-B/2 is located in the Northwest Territories on the southeastern edge of the Mackenzie Delta. The western map area is underlain by Quaternary fluvial deposits and parts of the central and northeast area by fluvial and fluvial fan deposits. The eastern area is underlain by poorly exposed Cretaceous strata, and the central area by poorly exposed Proterozoic and Paleozoic strata which comprise the southwestern Campbell Uplift. These Proterozoic and Paleozoic strata may be part of an earlier Paleozoic arch. However this feature is now part of the Tuk Horst (Wielens, 1992), which centers the Eskimo Lakes Arch. The horst features a complex subcrop of Paleozoic and Proterozoic sedimentary strata and local 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 is likely complex, and much of it Cretaceous"--Abstract.
