The Kakisa Formation is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin .
5-597: 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. The Kakisa Formation is composed of silty and dolomitic limestone . Reef builders such as corals and stromatoporoids can be identified in the formation. It is reefoid in its northern extent, where its thickness
10-688: Is disconformably overlain by the Trout River Formation and conformably overlays the Redknife Formation (east) or the Fort Simpson Formation (west). 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 . Kakisa River The Kakisa River is a major tributary of the Mackenzie River in
15-508: Is variable. The Kakisa Formation reaches a maximum thickness of 57 metres (190 ft). 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
20-688: The British Columbia border it turns north and flows back in the Northwest Territories. It keeps a north to northeast direction, paralleling the Redknife River for a while, then turns east, where it builds a complex lake and channel system before it empties into the Tathlina Lake at its western extremity. It flows out the north side of the lake and continues north, receives the waters of Gull Creek, then flows into
25-696: The Northwest Territories of Canada . The river gives the name to the Kakisa Formation , a stratigraphical unit of the Western Canadian Sedimentary Basin . The Kakisa River originates in northern Alberta , immediately south of the Northwest Territories border, from Creighton Lake, at an elevation of 570 meters (1,870 ft). It flows westwards, briefly crossing into the Northwest Territories, then back into Alberta. 3 kilometers (1.9 mi) east of
