Stratigraphy
Geological group:Alberta Formation:Wapiabi
Stratigraphic resolution:member
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Waipiabi Fm of the Alberta Gp. Overlies the Cardium Formation conformably or with only slight disconformity. The upper beds are gradational into the overlying Belly River Formation in the south and the Brazeau Formation in the central foothills. The unit passes eastward into shales of the upper Colorado Group and Lea Park Formation, to the north into the Puskwaskau, Bad Heart and Muskiki formations. AGE: Campanian, on the basis of ammonoid biostratigraphy; Baculites ovatus zone. STRATIGRAPHIC POSITION: List representing upper part of formation.
