Geology, Mount Peck, British Columbia / [by] M.E. McMechan and G.B. Leech. : M183-1/9-2011E-PDF
"Mount Peck map area (NTS 82-J/03, 1:50 000 scale) straddles portions of the Front Ranges and Main Ranges subdivisions of the southern Canadian Rocky Mountains. Folded Devonian, Mississippian, Pennsylvanian, Permian, and Triassic carbonate and clastic strata of the Bourgeau thrust sheet comprise the Front Ranges. Mississippi Valley - type alteration and zinc mineralization occur in Upper Devonian Palliser carbonate units east of a facies change into the basinal clastic rocks exposed in the Main Ranges. Large anticlines cored by cleaved Upper Cambrian and Lower Ordovician basinal clastic and carbonate strata, and large synclines cored by Ordovician, Devonian, and locally Mississippian strata characterize the Main Ranges. Complex northeast-facing, overturned folds and northeast-vergent thrust faults occur along the eastern edge of the Main Ranges. No large fault separates the Main Ranges from the Front Ranges. The Main Ranges reflect a culmination in the underlying Bourgeau Thrust. Substantial Middle Devonian gypsum deposits occur in the Lussier Syncline area"--Abstract.
