Baldonnel Formation
The Baldonnel Formation is a stratigraphic unit of Carnian age in the Western Canadian Sedimentary Basin.
It takes the name from the hamlet of Baldonnel, British Columbia, and was first described in the Pacific Fort St. John No. 16 well by L.M. Clark in 1957. A surface type locality can be found at Brown Hill, on the north shore of Williston Lake, at 56°06′51″N 122°48′39″W / 56.11404°N 122.81095°W.
The upper unit of the Baldonnel Formation consists of grey massive limestone and dolomite in the Canadian Rockies foothills and in the western range between the Liard River and Peace River. Siltstone and fine grained sandstone occur as interbeds.
In the sub-surface of the Peace River Country, the Baldonnel Formation is represented by porous and permeable dolomite.
Gas is produced from the Baldonnel Formation in north-eastern British Columbia.
The Baldonnel Formation occurs in outcrops in the Williston Lake area of the Canadian Rockies, and in the sub-surface from the Liard River to the Peace River Country.
It reaches a maximum thickness of 146 metres (480 ft) south of Hudson's Hope.
The Baldonnel Formation is the middle member of the Schooler Creek Group. It is conformably overlain by the Pardonet Formation limestone and siltstone or unconformably overlain by the Fernie Formation shale. North of the Williston Lake it overlies the dolomite beds of the Charlie Lake Formation.
