Abstract: 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.

Result: unknown Lineage: Lineage: Statement: This dataset contains modelled data of only the undeformed part of the Paskapoo Formation, which lies east of the Rocky Mountain fold-and-thrust belt. Process step: Process step: Description: B. Hathway (Alberta Geological Survey) made the stratigraphic picks of the base of the Paskapoo Formation. The base of the formation was picked based on the occurrence of the first thick (>=5 m) sand resting above the uppermost Ardley coal zone in the Scollard Formation. We entered the stratigraphic picks into a Microsoft Access database and imported them into ESRI ArcGIS software. Kriging algorithms were applied to generate a raster grid of the P20 structure of the base of the Paskapoo Formation (i.e., top of the Scollard Formation). Because of uncertainty in defining the Paskapoo-Scollard contact, we selected the P20 (twentieth percentile or low estimate) modelled surface as the datum for sand analysis of the Paskapoo Formation, which is about 5 m deeper than the P50 or median estimated surface. Selecting this surface ensured that sand bodies at the Paskapoo-Scollard interface that are less than 5 m thick were captured as part of the analysis of sand abundance in the Paskapoo Formation. We then converted the ArcGIS dataset into an ESRI ASCII grid format. Date and time: 2011-01-01T00:00:00
