Permo-Carboniferous strata of the Rocky Mountain Front Ranges between Banff and Jasper, Alberta, are described and correlated to the Mount Greenock section at Jasper and the type sections at Banff. Four conformable formations are recognized. In ascending order, these are the Exshaw, Banff, Rundle and Tunnel Mountain. The history and development of Permo-Carboniferous nomenclature of the Canadian Rockies is summarized.

The Upper Devonian or Lower Mississippian Exshaw Formation consists of approximately 35 feet of black shale. The Banff Formation, an argillaceous unit ranging from 900 to 1500 feet in thickness, contains four easily-recognizable members. Member A, composed of calcareous shales, is equivalent to type Lower Banff; Member B of interbedded limestones and shales is equivalent to type Middle Banff; Member C, a crinoidal limestone unit, is not present in type Banff and may be equivalent to the Pekisko Formation of southern Alberta; and Member D consists of argillaceous limestones equivalent to both type Shunda

and to most of type Upper Banff. Members A and B are considered to be Kinderhookian, and C and D Osagean in age. The Rundle Formation consists of from 800 to 2200 feet of carbonates. Two members are recognized: a lower member of light-coloured crinoidal limestones equivalent to the Osagean Livingstone formation, and an upper member of dark-coloured limestones equivalent to the Meramecian Mount Head Formation. The Tunnel Mountain Formation, the uppermost unit, consists of from 200 to 600 feet of silty dolomites ranging from Chesterian to Pennsylvanian in age.

Significant conclusions resulting from this study are that type Shunda is equivalent to most of type Upper Banff; and that the Tunnel Mountain Formation is a facies of the Rundle, becoming older north of Banff.
