Geology, Kananaskis Lakes, British Columbia-Alberta / [Author: M.E. McMechan]. : M183-1/11-2011E-PDF
"Kananaskis lakes map area (NTS 82-J/11, 1:50 000 scale) straddles parts of the Front Ranges and Main Ranges subdivisions of the Southern Canadian Rocky Mountains. Five major thrust faults (Misty, Rundle, Lewis, Sulphur Mountain, and Bourgeau) carrying variably folded Paleozoic and Mesozoic carbonate and clastic strata dominate the structural geology. A prominent zone of transverse faults, with a synsedimentary, basement-controlled origin, crosscut Paleozoic strata in each thrust sheet. A change in level of exposure to Cambrian, Ordovician, and Middle Devonian strata marks the transition into the Main Ranges. The southeastern termination of the Cambrian Kickinghorse Rim, an abrupt facies change from competent platform and ramp carbonate units to thick basinal strata, occurs in the western part of the area. Hydrothermal alteration localized immediately inboard of the rim produced zinc showings in the Albert River drainage. Six Late Ordovician to Early Devonian, mafic diatreme breccia pipes occur along the southeastern edge of the Main Ranges"--Abstract.
