Geology, Mount Abruzzi, British Columbia / [by] M.E. McMechan.: M183-1/10-2011E-PDF
"Mount Abruzzi map area (NTS 82-J/06, 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 are thrust over Lower Cretaceous foreland basin clastic strata in the Front Ranges. Mississippi Valley-type alteration occurs locally in southwesternmost exposures of Upper Devonian Palliser carbonate. A thick basinal succession of folded and cleaved Middle Cambrian to Lower Ordovician clastic and carbonate strata, and intensely folded Middle and Upper Ordovician and Middle Devonian, predominantly carbonate strata characterize the Main Ranges. No large fault separates the Main Ranges from the Front Ranges. The Main Ranges reflect a south-plunging culmination in the underlying Bourgeau Thrust. Sixteen Late Ordovician to Early Devonian, mafic diatreme breccia pipes occur in the northeastern part of the Main Ranges in the map area"--Abstract.
