- Description:
- Abstract:
- This is a 1000 m cell-sized raster dataset of the upper surface of the Lacombe Member aquitard, modelled from the >65% silt and clay point data derived by depth-slice analysis of well-log data. Alberta Geological Survey Bulletin 66 provides details on this grid dataset. The dataset is in ESRI ASCII grid format.
- Purpose:
- This dataset was generated to define the top of the Lacombe Member aquitard within the Paskapoo Formation.

- Data Quality Information:
- Attribute Accuracy:
- Attribute Accuracy Report:
- There could be a significant difference between sand values calculated at a borehole site and the modelled values assigned to the locations of the centre of regional 1000 m size grid cells.
- Logical Consistency Report:
- This raster dataset represents the amalgamated elevations of >65% average silt-clay values that are not overlain by sandy sediment in 25 m thick slices constructed parallel to the base of the Paskapoo Formation. The dataset is in ESRI ASCII grid format. Null data are coded '-9999'.
- Completeness Report:
- This dataset represents the elevation values from only those 25 m thick slices in the 3-D model in which the average silt-clay values exceed 65% and are not overlain by sandy sediment in the overlying 25 m thick slice. We only modelled the undeformed part of the Paskapoo Formation, which lies east of the Rocky Mountain fold-and-thrust belt, in this dataset. Refer to Alberta Geological Survey Bulletin 66 for a detailed description.

- Process Step:
- Process Description:
- We derived the three-dimensional data used to model the distribution of sandiness from the calculated average sand value of 25 m thick slice intervals in boreholes completed in the Paskapoo Formation. We subjectively defined the Lacombe aquifer based on the three-dimensional renderings of >65% silt-clay isovalues using Voxler ™ modelling software. The decision on how to assign a top to the three-dimensional body was based on the maximum height above the top of the Haynes sandstone that a silt-clay body extended before being covered by sandy sediment. We then transformed the grid to elevation above sea level by adding it to the elevation grid of the base of the Paskapoo. Refer to Alberta Geological Survey Bulletin 66 for more detail regarding methodology.
