Hollebeke Formation

The Hollebeke Formation is a Late Devonian Frasnian stratigraphic unit in the southern Rocky Mountains of Alberta and British Columbia, along the western edge of the Western Canada Sedimentary Basin. Named in 1965 by R.A. Price for Mount Hollebeke near North Kootenay Pass, it consists of marine carbonate rocks about 100 to 240 meters thick. Its lower beds are locally silty or argillaceous dolomite and limestone, and its upper part is very fine crystalline limestone. It occurs west of the Lewis Thrust Fault and south of about 50°N, resting unconformably on much older Cambrian, Ordovician, or late Precambrian rocks and overlain by the Borsato Formation.
