AbstractThe 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.
Summary(Plain Language Summary, not published)
This geological map of Campbell Lake is paired with the adjacent map of the Inuvik area to provide a modern compilation of the geologically significant Campbell Uplift, comprising sedimentary rocks that are much older than strata in the surrounding areas. These are the first detailed geological maps of the area. They incorporate significant new information that has accumulated in the 30 years since the original reconnaissance maps were published in 1981. This uplift provides important insights into the geological evolution of northwestern Canada over the past 500 million years.
