The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 31 of the Atlas, Petroleum Generation and Migration in the Western Canada Sedimentary Basin, Figure 3, Ordovician Petroleum System. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 27 of the Atlas, Geological History of the Williston Basin and Sweetgrass Arch, Figure 6, Lithotectonic Basement Elements. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 9 of the Atlas, Middle Ordovician to Lower Devonian Strata of the Western Canada Sedimentary Basin, Figure 21, Ordovician-Silurian Structure. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

This GIS dataset is a GIS version of AGS Map 178, linear features, as mapped at 1:250,000-scale by Fenton and Andriashek.

This dataset is a GIS version of Alberta Geological Survey (AGS) Map 146, polygon features, as mapped at 1:250,000 scale. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to AGS by PFRA in Arc/Info coverage format (map polygon features only). Data were subsequently checked and edited by AGS.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 9 of the Atlas, Middle Ordovician to Lower Devonian Strata of the Western Canada Sedimentary Basin, Figure 22, Ordovician-Silurian Subcrop/Outcrop Williston Basin. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 14 of the Atlas, Carboniferous Strata of the Western Canada Sedimentary Basin, Figure 33, Banff/Lodgepole Isopach and Lithofacies. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

This GIS dataset is a GIS version of Alberta Geological Survey Map 139, polygon features, as mapped at 1:250,000 scale. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to Alberta Geological Survey (AGS) by PFRA in Arc/Info coverage format (map polygon features only). Data were subsequently checked and edited by AGS.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 19 of the Atlas, Cretaceous Mannville Group of the Western Canada Sedimentary Basin, Figure 3, Sub-Mannville Unconformity. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

This GIS dataset comprises the geological polygon features of Map 180, Geology of the Precambrian Shield in northeastern Alberta, NTS 74M and NTS 74L, published by the Alberta Geological Survey (polygon features). The data are created in ArcInfo and output for public distribution in shapefile format.
