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.

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 is a 1000 m cell-sized raster grid dataset of the top of the sandstone of the Haynes member of the Paskapoo Formation. We mapped the sandstone using 3-D geostatistical modelling algorithms from data derived from sand calculations of 25 m thick slice intervals of the Paskapoo Formation. We selected the >55% sand isovalue to define sandstone, based on the results of mini-models that show vertical hydraulic connections being established if sand abundance is 55% or greater. This grid represents the upper surface of that three-dimensional body defined by the >55% sand threshold value.

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 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.

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 Aquifer Vulnerability Index (AVI) is a method of assessing the vulnerability of aquifers to surface contaminants in Alberta. An aquifer is a geological formation that is permeable enough to transmit sufficient quantities of water to possible to support the development of water wells. In the assessment of aquifer vulnerability to potential contamination, the depth to the aquifer and the types of geological materials above them are considered. For example, aquifers closer to the surface overlain with pervious surface materials are more vulnerable to contaminants, as compared to aquifers found deeper and covered with a thick layer of impervious material.

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
