The Muskeg Formation is a stratigraphical unit of Givetian age in the Western Canadian Sedimentary Basin.
It takes the name from the Muskeg arctic soil that covers the northern reaches of western Canada, and was first described in the California Standard Steen River 2-22-117-5W6M well (situated north of Zama Lake) by J. Law in 1955.
Lithology
The Muskeg Formation is evaporitic and carbonatic, with salt, anhydrite, dolomite and limestone.[1]
Distribution
The Muskeg Formation occurs in the northern half of the Elk Point Basin, in north-eastern British Columbia and north-western Alberta. It reaches a maximum thickness of 270 metres (890 ft).
Relationship to other units
The Muskeg Formation is disconformably overlain by the Watt Mountain Formation and is underlain by the Keg River Formation. It can be correlated with the Pine Point Formation, Presqu'ile Formation and Sulphur Point Formation.
