Description

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the net-to-gross sandstone ratio distribution within the Paskapoo Formation - Lower Composite Slice of the Sylvan Lake sub-basin. The Lower Composite Slice is one of three distinct geological domains identified in the Paskapoo Formation of the Sylvan Lake sub-basin model. Characterization of net-to-gross sandstone ratio distribution within the Paskapoo Formation provides information about the geological heterogeneity and potential hydraulic connectivity within the formation for input into a groundwater flow model. Alberta Geological Survey (AGS) Open File Report 2014-10 includes a full description of the process used to produce the net-to-gross sandstone ratio grid.

Description

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) C2, which contains the majority of fine-grained materials in the Neogene-Quaternary succession of the Sylvan Lake sub-basin and is the top boundary of the model domain. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

Description

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. The apparent great thickness (about 600 to 700 m) of aquifer along the deformation edge southwest of Drayton Valley is interpreted as an area of stacked, coarse fluvial deposits extending from the base of the Paskapoo Formation almost to surface.

Description

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.

Description

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. The bulk of the unit averages about 50 m in thickness. Given the great range in elevation of the top of the unit, but the relatively uniform thickness of the bulk of the aquifer, we inferred that most of the Haynes aquifer was deposited prior to major deformation with only the western-most parts showing evidence of infill of enhanced accommodation space. Most of the Haynes aquifer is overlain by thick muddy sediments of the Lacombe Member and only outcrops along its eastern edge.

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) S2, which contains coarse-grained material found in upland areas and discontinuously overlies buried valleys, as intradrift sand or terraces adjacent to and underlying present-day streams, rivers, and lakes in the Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

Description

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Paskapoo Formation, which is the bedrock surface in the Sylvan Lake sub-basin. The Paskapoo Formation is a highly heterogeneous system. To satisfy the needs of a groundwater flow model, internal characterization of rock properties was necessary to partition the formation into three distinct geological domains. The Upper Composite Slice is the uppermost of these three domains. Alberta Geological Survey (AGS) Open File Report 2014-10 includes a full description of the process used to produce this structure grid.
