This report contains a regional correlation of the Beaverhill Lake Group in the subsurface of Alberta, presented in the form of strike- and dip-oriented stratigraphic cross-sections. Lithostratigraphic units described in this report are the Watt Mountain Formation of the Elk Point Group (the top of which forms the base of the Beaverhill Lake Group), the Fort Vermilion Formation, the Slave Point and Swan Hills formations, and the Waterways Formation. Member-level stratigraphy within the Waterways Formation is discussed, but these units are not correlated within the study area. Picking criteria are outlined in an examination of representative wells from distinct geographic areas that encompass various depositional realms during the time the Beaverhill Lake Group was deposited.
Important carbonate depositional realms covered by the study area include (1) the Swan Hills Formation carbonate complexes of west-central and southwestern Alberta, (2) the Slave Point Formation carbonate complex of the Peace River region in northwestern Alberta, (3) the Slave Point Formation carbonate complex of the Hay River Platform in northwestern Alberta, and (4) the carbonate complex within the Waterways Formation - the Eastern Platform - in southeastern and east-central Alberta. Additionally, the evaporites of the Fort Vermilion Formation and the argillaceous carbonates and calcareous shales of the Waterways Formation, basinwards of the main carbonate complexes, are correlated and discussed. Measured depths of formation tops from cross-section wells are included in an appendix and are published as DIG 2014-0024.
