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-...

Bedrock Topography of Alberta (gridded data, ASCII format)

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

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 8 of the Atlas, Middle Cambrian to Lower Ordovician Strata of the Western Canada Sedimentary Basin, Figure 19, Cambrian and Lower Ordovician Isopach. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.
