Peace River Formation

The Peace River Formation is a middle Albian geologic unit in Alberta and northeastern British Columbia within the Western Canadian Sedimentary Basin. First described by McConnell in 1893 along the Peace River, it consists of greywacke, coal, marine sandstone, and dark non-calcareous fissile shale, averaging about 20 meters thick. Its Paddy Member is confined to northern Alberta, while the Cadotte and Harmon members extend into British Columbia. Part of the Fort St. John Group, it lies conformably between the Spirit River and Shaftesbury formations and correlates with several regional units. It is also economically important because natural gas is produced from its Cadotte Member in northwestern Alberta.
