"Mount Assiniboine map area (NTS 82-J/13, 1:50 000 scale) straddles portions of the Front Ranges, Main Ranges, and Western Ranges subdivisions of the southern Canadian Rocky Mountains, from northeast to extreme southwest. Thrusts carrying folded Ordovician, Devonian, and Mississippian carbonate and clastic strata characterize the Front Ranges, where Upper Devonian Fairholme Group strata change facies from reef to basinal deposits. At the Middle and Upper Cambrian Kickinghorse Rim, an abrupt westward facies change from competent platform and ramp carbonate units to thick basinal strata, divides the Main Ranges into eastern broadly folded and western penetratively deformed parts. Tight and overturned northeast-facing folds occur immediately west of the Kickinghorse Rim. Boulders and blocks shed from the rim are spectacularly exposed near Indian Peak. Hydrothermal alteration localized at the rim produced magnesite ore near Mount Brussilof. Folded Lower to Upper Ordovician strata cut by steep to overturned thrusts characterize the Western Ranges"--Abstract.
