Stoddart Group
Introduction The '''Stoddart Group''' is a stratigraphical unit of Mississippian to Early Pennsylvanian age in the Western Canadian Sedimentary Basin.It takes the name from the Stoddart Creek, a creek that flows into Charlie Lake north of Fort St. John, and was first described in well Pacific Fort St. John #23 (at depths from 2000 to 2600m) by A.T.C. Rutgers in 1958.
Lithology The Formation is composed of both carbonate and clastic facies.
Distribution The Stoddart Group reaches a maximum thickness of  in the sub-surface north of Fort St. John in north-eastern British Columbia. It is present in the sub-surface from the foothills of the Northern Rockies and eastwards into the Peace River Country in north-western Alberta.
Subdivisions The Stoddart Group is composed of the following formations, from top to bottom: Sub-unit  Age  Lithology  Max.Thickness  ReferenceTaylor Flat Formation  Early Pennsylvanian  limestone, dolomite, occasional sandstone, calcareous shale  Kiskatinaw Formation  Chesterian  quartzose sandstone, dark grey shale, rare carbonate  Golata Formation  late Meramecian-Chesterian  fossiliferous limestone, shales, occasional siltstone, coal and anhydrite
Relationship to other units The Stoddart Group is overlain by the Ishbel Group in the foothills and the Prophet Formation in the northern plains; it  conformably overlays the Debolt Formation.It can be correlated with the Tunnel Mountain Formation, the Kananaskis Formation, the Mattson Formation and the Mount Head Formation of the southern Canadian Rockies, and with the Amsden Formation in Montana.
