Alberta Geological Survey Bulletin 64 documents 190 metallic mineral occurrences. We have digitized these occurrences into GIS format as a point shapefile. The description of these 190 metallic mineral occurrences on the exposed Precambrian Shield of northeast Alberta provides models for mineral deposition, establishes exploration targets and gives insights into the economic potential of the mineral showings. Commodities include gold, uranium, base metals and rare-earth elements. Among these occurrences, we have investigated 20 of them sufficiently, and they are of sufficient exploration importance to be classified as a mineral showing.

This GIS dataset is part of a digital compilation of the Precambrian geology of the Alberta portion of the Canadian Shield and Athabasca Basin. It is one of the datasets used to produce Alberta Geological Survey Map 537. The dataset displays locations on the Alberta shield where we took rock samples for 40 argon/39 argon dating. Attributes include crystallization and/or cooling age, mineral analyzed, sample identifier and rock type, literature reference, and analytical method. This is a digital version of Table 2 in Map 537.

This GIS dataset is part of a digital compilation of the Precambrian geology of the Alberta portion of the Canadian Shield and Athabasca Basin. It is one of the datasets used to produce Alberta Geological Survey (AGS) Map 537. For the Alberta shield, the compilation integrates detailed mapping by both AGS and the Geological Survey of Canada (GSC) at scales ranging between 1:31,680 and 1:250,000. Geochronological data and interpretations also helped prepare this dataset. For the Athabasca Basin, the compilation incorporates the geology of the basin presented in the ExTech IV volume, published in 2007 by the GSC. This dataset tries to present the geological information in a neutral manner, unbiased by the three mutually exclusive, regional tectonic concepts existing at the time of compilation. Users are encouraged to view AGS Map 537, which contains overviews of the geology of the respective areas and a complete reference list. The polygon feature dataset came from existing, though largely unpublished, digital sources. Areas of the shield are mainly from digitized versions of AGS Maps 180 and 25: the shield north of Lake Athabasca and south of the Athabasca Basin, respectively. The selected polygons were from GSC maps, which Alberta Geological Survey digitized, generalized and integrated into the compilation. The author gave new or updated descriptions to the map units and assigned them to the polygon attribute table.

This GIS dataset is part of a digital compilation of the Precambrian geology of the Alberta portion of the Canadian Shield and Athabasca Basin. It is one of the datasets used to produce Alberta Geological Survey Map 537. The dataset displays Alberta shield locations where we took rock samples for uranium-lead dating. Alberta Geological Survey compiled the data from published literature. Attributes include crystallization and/or cooling age, mineral analyzed, sample identifier and rock type, literature reference, and analytical method. This is a digital version of the data given in Table 1 of Map 537.

This GIS dataset is part of a digital compilation of the bedrock geology of Alberta. It is one of the datasets used to produce Alberta Geological Survey (AGS) Map 600. This dataset represents the compilation of existing geological maps and original geological mapping by AGS staff. Mapping in support of the dataset 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 geodatabase format and output for public distribution in shapefile format. AGS Open File Report 2013-02 presents additional information on data sources related to this dataset.
