Description

The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation. This grid is a computer-generated geostatistical model of the bedrock topography of Alberta using previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data. The quality of this data has been assessed and then a quality-weighting approach was applied to the dataset prior to interpolation. The surface was modelled using a 500m x 500m grid cell spacing, and as such should not be used for local scale studies. This grid represents the surface portrayed in AGS Map 602, Bedrock Topography of Alberta, and this grid will continue to be updated as part of the Alberta Geological Framework project. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of...

Description

This GIS dataset is a result of the compilation of all existing Alberta Geological Survey sand and gravel geology and resource data into digital format. Data sources include Alberta Geological Survey maps and reports produced between 1976 and 2006. References are provided as an attribute so the user can refer back to the original maps and reports. Attributes include study level, material description, references, area, sand and gravel thickness, and gravel and sand volumes. In 2009, data from newly mapped area NTS 83N/NE were added.

Description

This data set comprises the bedrock geology of Alberta in geographic information systems (GIS) format. The GIS coverage was originally prepared by digitizing Map 027, 1972, Alberta Geological Survey, Alberta Research Council. Revisions since 1972 have incorporated new mapping data from work by the Alberta Geological Survey and the Geological Survey of Canada, and by the Canadian Society of Petroleum Geologists through the contribution of its membership to the Geological Atlas of the Western Canada Sedimentary Basin. The coverage shows the formation and geologic age of the bedrock subcrop, as well as the nature of the contacts between formations. GIS files are distributed as shapefiles of bedrock polygons (geol_py_ll.shp), bedrock line features (bdrk_ln_ll.shp), and bedrock contacts (geol_ln_ll.shp).

Description

This data set is an updated, GIS version of part of the Alberta Geological Survey's published Map No. 226, which in turn is a regional synthesis of various published and unpublished maps. The data represent the locations of thalwegs (paleo-channels) incised in the bedrock surface.

Surficial Geology, Alberta Foothills and Rocky Mountains (GIS data, polygon features)

Description

This GIS dataset is a GIS version of AGS Map 150, Sheets 1 - 6, as mapped at 1:250,000-scale by Bayrock and Reimchen. Digitizing was originally done by Prairie Farm Rehabilitation Administration... More ≫

Description

This GIS dataset is a GIS version of AGS Map 150, Sheets 1 - 6, as mapped at 1:250,000-scale by Bayrock and Reimchen. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to AGS by PFRA in individual map sheets, in Arc/Info coverage format. Data were subsequently checked and edge-matched to create a single polygon coverage. Some rubber-sheeting and other edits were done during the checking and correction process.

Description

This dataset is a GIS version of Map 226, which is a regional synthesis of published and unpublished maps. The data represent 100 m elevation contours of the bedrock subcrop for Alberta. The southern part of Alberta, from 49 to 56 degrees north, was primarily compiled from existing 1:250,000 bedrock topography maps. The interpretation of the remaining northern portion of Alberta was based mostly on limited borehole data and information from existing 1:250,000 hydrogeological maps.
