Description

Locations of uraniferous boulder-fields and uraniferous swamps extracted from industry assessment reports are useful metallogenetic indicators for uranium exploration within and around the Athabasca Basin. They are used as pathfinders to uranium occurrences and prospects. These locations along the northern rim of the Athabasca Basin in Alberta have been compiled in GIS format and delivered as a point shapefile. In Alberta, the northern rim of the Athabasca Basin and the regolith underlying the Athabasca unconformity are locally exposed along the northern shore of Lake Athabasca. Extensive uranium exploration work in the 1970s, including scintillometer prospecting traverses, geological mapping, airborne and ground geophysics, and drilling, have documented several uraniferous outcrops with scintillometer readings of up to 10 000 counts per second, and uraniferous boulders and boulder trains with radioactivity up to two orders of magnitude higher than the background. Near the Alberta-...

Description

This GIS dataset is a compilation of existing surficial map information for Alberta tiled into one layer. It was an interim product to produce the generalized polygon dataset (Alberta Geological Survey DIG 2013-0002), which is suitable for presentation and use at 1:1,000,000 scale. We prepared the data by appending existing GIS datasets of each surficial map of Alberta into one provincial layer with a standard attribute table. Data sources included published Alberta Geological Survey and Geological Survey of Canada maps, one master's thesis, and ecological (biophysical) land-classification maps of the mountain parks. When possible, we transferred all of the legend data from each map source into the standard schema. As part of our 1:1,000,000-scale map project, we completed mapping the unmapped areas of Alberta at roughly 500,000 to 1,000,000 scale. This dataset includes those previously unpublished data. With this dataset users can, for the first time, view the surficial geology of...

Surficial Geology of Alberta, 1:1,000,000 scale (GIS data, polygon features)

Description

This GIS dataset is a compilation of existing surficial map information for Alberta, edited for mapping continuity and generalized to make it suitable for presentation and use at 1:1,000,000 scale. It is the dataset used to create Alberta Geological Survey Map 601: Surficial Geology of Alberta. The data were prepared from an intermediate dataset (Alberta Geological Survey DIG 2013-0001), which was edgematched and then the boundaries between similar polygons were 'dissolved.' The residual dataset was then generalized selectively using the Geological Survey of Canada's GeoScaler software. We then added attributes describing the generalized polygons, including unit description, texture, genetic group, and geological age. The data were created as an Esri file geodatabase feature class and exported for public distribution as an Esri shapefile called Surf1M_py_ll.shp. The layer file Surf1M_py_ll.lyr is also included for the convenience of Esri software users (version 9.2).

Description

This GIS dataset represents a reclassification of existing surficial map information for the purpose of portraying the distribution of sand and gravel deposits in Alberta. The surficial geology of Alberta ungeneralised digital mosaic (Alberta Geological Survey DIG2013-0001) represents the primary source of information used in this reclassification. This dataset was updated with more recently published 1:100,000 scale surficial geology maps, and where appropriate new polygon features that were digitized from line features in the Glacial Landforms of Alberta (Alberta Geological Survey Map 604 and DIG2014-0022). The updated surficial geology mosaic was then reclassified using a thematically-based attribute table which categorizes the original surficial geology features based on their sand and gravel component. Attributes within this table comprise: (1) an approximation of the material type (MATERIAL). (2) the aerial proportion that this material represents of the polygon, as a...

Description

This GIS dataset is a compilation of existing surficial map information for the Calgary-Lethbridge Corridor area tiled into one layer. It is suitable for presentation and use at 1:250 000 scale. The dataset was prepared by appending existing GIS datasets into one layer with a standard attribute table. These datasets were then compared against surficial maps for which GIS data were unavailable. Lastly, polygon boundaries were modified to agree with the surface topography as represented by a digital elevation model (DEM) with a grid cell size of 25 metres. Data sources included published Alberta Geological Survey and Geological Survey of Canada maps and the Agricultural Regions of Alberta Soil Inventory Database Version 4.0. Legend information for each polygon was translated by the author into the standard schema. This dataset contains the polygon features of Alberta Geological Survey Map 579, Surficial Geology of the Calgary-Lethbridge Corridor, and has been exported in shapefile...
