Geology, Tangle Peak, British Columbia / Authors, M.E. McMechan and G.B. Leech.: M183-1/12-2011E-PDF
"Tangle Peak map area (NTS 82-J/12, 1:50 000 scale) straddles portions of the Main Ranges and Western Ranges subdivisions of the southern Canadian Rocky Mountains, from northeast to southwest. 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. Hydrothermal alteration localized immediately inboard of the Kickinghorse Rim produced magnesite in the Cross River area and zinc showings in the Albert River drainage. Tight and overturned, northeast-facing folds occur in basinal strata immediately west of the rim whereas, a regional southwest-facing, overturned fold occurs at the transition into the Western Ranges. Folded Cambrian to Middle Devonian strata cut by steep longitudinal and transverse faults characterize the Western Ranges. Thick breccia units occur along several faults. Middle Devonian gypsum deposits occur in the Windermere Creek area"--Abstract.
