The Kakisa Formation is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin.
It takes the name from the Kakisa River, a tributary of the Mackenzie River, and was first described in outcrop on the banks of the Trout River by H.R. Belyea and D.J. McLaren in 1962. [2]
The Kakisa Formation is composed of silty and dolomitic limestone. [1] Reef builders such as corals and stromatoporoids can be identified in the formation. It is reefoid in its northern extent, where its thickness is variable.
The Kakisa Formation reaches a maximum thickness of 57 metres (190 ft). [1] it occurs at the surface in outcrops along the Kakisa River between Tathlina Lake and Kakisa Lake and as an escarpment along the Mackenzie River. In the sub-surface, it can be found in north-eastern British Columbia, where it is typically 30 metres (100 ft) thick, and thins out towards the Peace River Arch.
The Kakisa Formation is disconformably overlain by the Trout River Formation and conformably overlays the Redknife Formation (east) or the Fort Simpson Formation (west). [1]
It is equivalent to parts of the Winterburn Group in central Alberta. Towards the west, it becomes shaley and turns into the Fort Simpson Formation.
The Cadomin Formation is a stratigraphic unit of Early Cretaceous age in the western part of the Western Canada Sedimentary Basin. It is extends from southeastern British Columbia through western Alberta to northeastern British Columbia, and it contains significant reservoirs of natural gas in some areas. It was named after the mining town of Cadomin, which is an acronym of "Canadian Dominion Mining".
The Belloy Formation is a stratigraphical unit of Permian age in the Western Canadian Sedimentary Basin.
The Redknife Formation is a stratigraphical unit of Devonian age in the Western Canadian Sedimentary Basin.
The Schooler Creek Group is a stratigraphic unit of Middle to Late Triassic age in the Western Canadian Sedimentary Basin. It is present in northeastern British Columbia. It was named for Schooler Creek, a left tributary of Williston Lake, and was first described in two oil wells northwest of Fort St. John, by F.H. McLearn in 1921. Exposures along Williston Lake serve as a type locality in outcrop.
The Baldonnel Formation is a stratigraphical unit of Carnian age in the Western Canadian Sedimentary Basin.
The Horn River Formation is a stratigraphic unit of Devonian age in the Western Canadian Sedimentary Basin.
The Fort Simpson Formation is a stratigraphical unit of Devonian age in the Western Canadian Sedimentary Basin.
The Beaverhill Lake Group is a geologic unit of Middle Devonian to Late Devonian age in the Western Canada Sedimentary Basin that is present in the southwestern Northwest Territories, northeastern British Columbia and Alberta. It was named by the geological staff of Imperial Oil in 1950 for Beaverhill Lake, Alberta, based on the core from a well that they had drilled southeast of the lake, near Ryley, Alberta.
The Woodbend Group is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin.
The Trout River Formation is a stratigraphical unit of Late Devonian age in the Western Canadian Sedimentary Basin.
The Tetcho Formation is a stratigraphical unit of Famennian age in the Western Canadian Sedimentary Basin.
The Kotcho Formation is a stratigraphical unit of middle Famennian age in the Western Canadian Sedimentary Basin.
The Besa River Formation is a stratigraphical unit of Devonian age in the Western Canadian Sedimentary Basin.
The Slave Point Formation is a stratigraphical unit of Middle Devonian age in the Western Canadian Sedimentary Basin.
The Crowfoot Formation is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin.
The Nahanni Formation is a stratigraphical unit of Givetian age in the Western Canadian Sedimentary Basin.
The Grosmont Formation is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin.
The Alexo Formation a stratigraphic unit of Late Devonian age. It is present on the western edge of the Western Canada Sedimentary Basin in the central Rocky Mountains and foothills of Alberta. The formation consists primarily of dolomite. It is locally fossiliferous and includes remains of marine animals such as brachiopods and conodonts.
The Cairn Formation is a geologic formation of Late Devonian (Frasnian) age in the Western Canada Sedimentary Basin. It was named for the Cairn River near its junction with the Southesk River in Jasper National Park by D.J. McLaren in 1955.
The Sassenach Formation is a stratigraphic unit of Late Devonian age. It is present on the western edge of the Western Canada Sedimentary Basin in the Rocky Mountains and foothills of Alberta. It consists primarily of mudstone, siltstone, and silty carbonate rocks, and was named for Mount Sassenach in Jasper National Park by D. J. McLaren and E. W. Mountjoy in 1962.
