| Abstract | The region encompassed by Upper Ramparts River and Sans Sault Rapids map areas contains 20 647 km 2 and includes parts of Mackenzie Mountains, Peel Plateau, Peel Plain. Mackenzie Plain, and Franklin
Mountains. The cumulative stratigraphic column of the region exceeds 8840 m in thickness, although this total is not known to have accumulated at any single point. The country is subdivided into two distinct regions on the basis of stratigraphy. The
first of these. and the one represented by all of Sans Sault Rapids and most of Upper Ramparts River map areas, behaved as a stable platform from Helikian through Devonian time; Hadrynian and Lower Cambrian rocks are almost entirely missing, and
Paleozoic strata are mainly carbonates. The second region, occupying only the southwest corner of Upper Ramparts, is Selwyn Basin. where a thick Hadrynian and Lower Cambrian succession is present and the lower and middle Paleozoic carbonates of the
platform change facies to shale. No sedimentary record of late Paleozoic through Jurassic time is preserved. A thick and mostly marine Cretaceous succession is present northeast of the Mackenzie Mountains. Cenozoic strata were not observed. The
obvious structures of the region. west-northwesterly trending. large-scale folds and subordinate contractional faults are. broadly. Laramide in age. The structural style is governed by the presence of kinematically related detachments at three
different stratigraphic levels. Mackenzie Mountains and the crestal regions of Franklin Mountains uplifts are judged to be devoid of hydrocarbon potential. The remainder of the two map areas is considered to have moderate potential for oil or gas
production from stratigraphic traps. The Paleozoic and older sedimentary successions of Mackenzie Mountains show promise for production of zinc, lead and copper. |
