Stratigraphy
| Geological group: | Smoky | Formation: | Kaskapau | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: Belonging to the Smoky Group. The Kaskapau is conformable with the underlying continental Dunvegan Formation in northeastern British Columbia and most of the Alberta Peace River area, with a transitional lithology except in the vicinity of Watino, Alberta, where the contact is abrupt and the Dunveganoceras Zone seems to be missing. The Kaskapau Formation is conformably overlain by the Bad Heart Formation in the Smoky River area. AGE: Cenomanian, on the basis of ammonoid and foraminiferal biostratigraphy. STRATIGRAPHIC POSITION: From unknown position in local section. | |||||
