Bedrock Geology of the Foremost Area (NTS 72E) (GIS data, line features)

Author(s) Glombick, P.M. Date 2014-04-02

This GIS dataset is part of a digital compilation of the bedrock geology of the Foremost area (NTS 72E). It is one of the datasets used to produce Alberta Geological Survey (AGS) Map 568.

This dataset represents the compilation of existing geological maps and original geological mapping by AGS staff. Mapping included field observations and creating three-dimensional models of subsurface stratigraphy based on the interpretation of geophysical logs from oil and gas wells. Each three-dimensional formation surface was projected to a model of the bedrock surface, and the intersection formed the first approximation of the position of the geological contact at the base of the surficial deposits. We adjusted these preliminary contacts to honour outcrop data and the interpretation of the bedrock unit immediately below surficial deposits in individual wells.

The data were created in file geodatabase format and output for public distribution in shapefile format.

AGS Open File Reports 2010-10 and 2011-13 present additional information on data sources related to this dataset.
