Provincial

This dataset maps the thickness of the Lacombe aquitard as defined by outputs of a 3-D model of sandiness in the Paskapoo Formation. The Lacombe aquitard consists of >65% non-sandy material in stacked, 25 m thick slices above the base of the Paskapoo Formation.

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.

This dataset represents the topography of the top of the Paskapoo Formation, which is also the bedrock topography in the western part of Alberta. We clipped the surface from Alberta Geological Survey's Bedrock Topography of Alberta grid using the areal extent of the Paskapoo Formation shown on Alberta Geological Survey Map 236, Geological Map of Alberta. The dataset is in ESRI ASCII grid format

Sand bodies within the Sunchild aquifer subcrop over most of its extent, and because overlying Neogene sediment is relatively thin in the western part of the Paskapoo Formation, the unit expresses itself as the present-day topography. Constructing the Sunchild aquifer-thickness map was somewhat problematic because of the difficulty of mapping the step-like distribution and connection of sand bodies that, in places, are laterally adjacent to muddy intervals. The resultant isopach was generated by subtracting the Lacombe Member surface from the Sunchild surface to yield an approximation of Sunchild aquifer thickness. The Sunchild aquifer thickens from less than 50 m in the east to more than 300 m to the west.

This dataset is a grid of the thickness of the Haynes aquifer within the Paskapoo Formation. The Haynes aquifer is a regionally extensive body of sand that lies in the bottom part of the Paskapoo Formation. The isopach was created from the modelled results of the average sandiness of 25 m thick slices in boreholes completed within the Paskapoo Formation. Parts of the aquifer are as much as 100 m thick, particularly in the west near the deformation belt and in a region west of the city of Red Deer.

This digital dataset represents the modelled outputs of the three-dimensional distribution of sandiness in the Paskapoo Formation, Alberta, Canada. Sand-abundance values were determined from log analysis of water-well lithologs and petroleum exploration downhole-geophysical logs, specifically gamma-ray logs. We derived the sandiness values by calculating the average sandiness in 25 m thick slices above the base of the Paskapoo Formation in a borehole and by assigning the average value (P50) to the midpoint of each slice interval. Alberta Geological Survey Bulletin 66 provides detailed descriptions of the methodology.

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 17 of the Atlas, Paleographic Evolution of the Western Canada Foreland Basin, Figure 14, Horseshoe Canyon/Scollard/Paskapoo/Ravenscrag Paleogeography. 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.
