The dataset accompanies Alberta Geological Survey Open File Report 2009-01. The dataset contains the results of geochemical analyses of rock samples from the Bad Heart Formation, Clear Hills region and Smoky River region (northwestern Alberta) collected by Alberta Geological Survey from 2004 to 2007. The data comprise elemental analyses of 325 rock samples, including ooidal ironstone, ooidal sandstone, sandstone, siltstone, shale, Bad Heart rubble and till, and conglomerate.

This is a raster dataset of the thickness of the Paskapoo Formation. It is a derived dataset created by the subtraction of the base of the Paskapoo Formation from the top of the formation, which in the western part of Alberta is also the bedrock topography. The gridded isopach data cover only the undeformed part of the Paskapoo Formation that extends west to the front ranges of the Rocky Mountains. The isopach data do not include those parts of the formation affected by tectonic folding or thrusting. The dataset is in ESRI ASCII grid format.

These structure, isopach and zero edge files are part of a series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project.The series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project have been produced using 2 km equi-spaced modified grids generated from Golden Software’s Surfer 9 kriging algorithm. The dataset used to produce each of the maps in this series was created using data from several projects completed by the Ministry (Christopher, 2003; Saskatchewan Industry and Resources et al., 2004; Kreis et al., 2004; Marsh and Heinemann, 2006; Saskatchewan Ministry of Energy and Resources et al., 2007; Heinemann and Marsh, 2009); these data were validated and edited as required to facilitate correlations between the various regional projects. In addition, to minimize edge effects during contouring, the senior author also generated stratigraphic data from wells in adjacent jurisdictions.

The base of the Paskapoo Formation is unconformable with the underlying Scollard Formation. Alberta Geological Survey differentiates the Paskapoo Formation from the underlying Scollard Formation by the first thick sandstone above the uppermost coal seam of the Ardley coal zone. We defined 'thick sandstone' to be 5 m or more thick. This dataset contains the gridded results of the structural surface of the base of the Paskapoo Formation modelled from stratigraphic picks of the >5 m sand above the Scollard Formation coal from oil and gas industry gamma-ray logs. We modelled only the undeformed part of the Paskapoo Formation, which lies east of the Rocky Mountains deformation belt. Because of uncertainty in defining the Paskapoo-Scollard contact, we selected the P20 (20th percentile or low estimate) modelled surface of those data, which is about 5 m deeper than the P50 or median estimated surface. Subsequent boundaries of slices were constructed parallel to this surface, recognizing that, locally, the base of the Paskapoo Formation has an undulating to incised erosional contact with the underlying Scollard Formation. The model illustrates an elongated, concave surface with a central region plunging westwards towards the Alberta syncline and elevated limbs to the northwest and southeast.

All available bathymetry and related information for South Heart Reservoir were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

This digital data release includes helium pycnometry results of selected samples for analyses of shale- and siltstone-hosted hydrocarbons. The strata evaluated include the: - basal Banff Formation, - Colorado Group, - Duvernay Formation, - Exshaw Formation, - Montney Formation, - Muskwa Formation, - Wilrich Formation, - Nordegg Member, and - Rierdon Formation.

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 23 of the Atlas, Cretaceous Cardium Formation of the Western Canada Sedimentary Basin, Figure 2, Cardium Formation Isopach. 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 Town dataset is comprised of all the polygons that represent Towns in Alberta. Town is a municipality type defined under the authority of the Municipal Government Act. The formation of a Town can occur if a majority of buildings are on parcels of land smaller than 1850 square metres and there is a population of 1000 or more.
