The Titkana Formation formed as a shallow marine shelf along the western shoreline of the North American Craton during Middle Cambrian time.[3][4] Some of the original limestone was subsequently altered to dolomite.[1]
Distribution and stratigraphic relationships
The Titkana is present in the northern Canadian Rockies of Alberta and British Columbia where it reaches thicknesses of up to about 520 metres (1700 ft). It conformably overlies the Pika Formation and is unconformably overlain by the Tatei Formation. It is equivalent to the Eldon Formation in the southern Canadian Rockies.[1]
