The Kananaskis Formation is a geologic formation that is present on the western edge of the Western Canada Sedimentary Basin in the southern Canadian Rockies of western Alberta.[2] Named after the Kananaskis Range near Banff,[3] it was deposited during the Late Pennsylvanian sub-period of the Carboniferous period.[1][3] Some of its strata host fossils of marine invertebrates.[1]
The Kananaskis Formation consists primarily of pale grey weathering, thick- and thin-bedded silty limestone and dolomite, with beds and nodules of chert, chert breccias and conglomerates, and quartzites.[1][3]
Paleontology
Fusulinids, spiriferid brachiopods, gastropods, and sponge spicules have been described from some of the beds in the Kananaskis Formation.[1][4]
