The lithogeochemical data provides the chemical composition of rock samples. This data helps characterize the rocks and can be used to understand their mode of formation.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

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.

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.

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 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.

The City dataset is comprised of all the polygons that represent Cities in Alberta. City is a municipality type defined under the authority of the Municipal Government Act. The formation of a City can occur when a majority of the buildings are on parcels of land smaller than 1850 square meters and there is a population of 10 000 or more.

This data release includes fluid saturation 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, - Nordegg Member, and - Rierdon Formation.

The Village dataset is comprised of all the polygons that represent Villages in Alberta. Village is a municipality type defined under the authority of the Municipal Government Act. The formation of a Village can occur when a majority of the buildings are on parcels of land smaller than 1850 square meters and there is a population of 300 or more.

Land Plats illustrate in map view the oil or gas Spacing Areas delimited in a pool, and names the geological formation in which the pool is recognised. Land Plats are the sole official record of where the Director of PandNG Titles Branch recognizes a pool of hydrocarbons to exist for the purpose of administering oil and gas title

The Municipal District dataset is comprised of all the polygons that represent Municipal Districts in Alberta. Municipal District is a municipality type defined under the authority of the Municipal Government Act. The formation of a Municipal District occur when a majority of the buildings used as dwellings are on parcels of land with an area of at least 1850 square meters and there is a population of 1000 or more. A municipal district is a government form in rural areas of the province.
