AbstractThe southeast Sans Sault Rapids map area (NTS 106-H/SE) covers the transition from the northern Mackenzie Mountains to the Mackenzie Plain and northwest Franklin Mountains of the Northwest Territories. Bedrock exposures in the area include carbonate and siliciclastic strata ranging from Neoproterozoic (Tonian) to Cretaceous age. These strata were deformed in Cretaceous to Eocene time by folding and contractional faulting associated with Cordilleran deformation. Major structures include the Stony and Imperial anticlines. A minor set of pre-Cordilleran extensional faults are preserved within Neoproterozoic strata of the Mackenzie Mountains Supergroup, and are locally associated with diabase or gabbro dykes assigned to the Gunbarrel magmatic event (~780 Ma). Variable preservation of Neoproterozoic units beneath the sub-Cambrian unconformity indicates tilting or warping of strata before Cambrian time. A second major unconformity between Devonian and Cretaceous strata is marked by low-angle truncation of Paleozoic strata beneath the Cretaceous units.
Summary(Plain Language Summary, not published)
This publication is a bedrock map of the southeast quadrant of the Sans Sault Rapids map area (NTS 106H) in northern Mackenzie Mountains, Northwest Territories. It illustrates the distribution of sedimentary rocks of Neoproterozoic to Cretaceous age along with structural features such as folds and faults.
