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 20c, Middle Cambrian Lithology Shale. 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.

This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The Base Watersheds data was created by re-working and post-processing the digital elevation data from the Alberta Provincial Digital Elevation Model, the digital hydrography data from the Base Stream and Flow Representation Lines, the Base Waterbody Polygons and the Base Hydrography Point Events and the digital boundaries of the ATS Version 4.1 Alberta Provincial Boundary. The digital elevation data was hydrologically corrected using simplified versions of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons. The digital watersheds were created using the hydrologically corrected filled Alberta Provincial Digital Elevation Model data as a base and the simplified versions of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons as pour points. The routes were created from the raw and simplified versions of the Base Stream and Flow Representation Lines using the names or the longest stream as the base. Strahler Order coding was applied to the simplified version of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons as well as the digital watersheds. Hydrocoding was applied to the routes. The reaches were not created but would be generated using the simplified version of the Base Stream and Flow Representation Lines as a base and the hydrologically corrected filled Alberta Provincial Digital Elevation Model plus the Base Hydrography Point Events to determine the breaks. The Base Watersheds consists of four data packages: Base Watersheds - Hydrologically Corrected Filled Digital Elevation Model (DEM), Base Watersheds - Simplified Hydrography, Base Watersheds - Watersheds and Base Watersheds - Routes. The four data packages are composed of: Base Watersheds Hydrologically Corrected Filled Digital Elevation Mode (DEM) Hydrologically Corrected Fully Filled Terrain Hydrologically Corrected Fully Filled 25 Metre Raster Hydrologically Corrected Fully Filled 100 Metre Raster Hydrologically Corrected Partially Filled Terrain Hydrologically Corrected Partially Filled 25 Metre Raster Hydrologically Corrected Partially Filled 100 Metre Raster Simplified Hydrography Simplified Linear Network Lines Simplified Linear Network Points Simplified Hydropolygons Simplified Linear Network Cross Reference Simplified Hydropolygons Cross Reference Strahler Order Coding Watersheds Fully Filled Watersheds Partially Filled Watersheds Strahler Order Coding Routes Single Line Network Routes Simplified Linear Network Routes Hydrocoding These feature datasets, feature classes and tables were generated using the Base Features Derived Watersheds and Hydrocoding Specifications documents. There are six documents in this collection: Overview Strahler Order Coding Filled Hydrologically Corrected Terrain Watersheds Hydrocoding Reaches Full descriptions of the individual datasets are included in the metadata for the four data packages.

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 10 of the Atlas, Devonian Elk Point Group of the Western Canada Sedimentary Basin, Figure 7, Distribution of Lower Givetian Strata. 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.

In 2010, for the Alberta Geological Survey Saline Aquifer Mapping Project, we collected and analyzed 38 water samples from oil wells producing from geological units, including the Glauconitic, Ostracod, Ellerslie, Banff, Wabamun, Nisku, Leduc and Cooking Lake, within 100 km of Edmonton, Alberta. We analyzed filtered water samples for pH, density and specific conductance. oxygen, hydrogen and strontium isotopes. and dissolved constituents, including sodium, potassium, calcium, magnesium, barium, strontium, lithium, iron, manganese, chloride, bromide, sulphate, sulphide, silica and inorganic carbon.

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 12 of the Atlas, Devonian Woodbend-Winterburn Strata of the Western Canada Sedimentary Basin, Figure 16, Majeau Lake Isopach and Lithofacies. 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.

The AMDO (Alberta Mineral Deposits and Occurrences) application was created by the Minerals and Coal Geoscience Section of the Alberta Geological Survey as a database for mineral deposits in Alberta in the early 1990s. It was originally released as Open File Report OFR 1991-17. Industrial minerals from that data source have been extracted into Microsoft Access, their locations refined or corrected and presented in GIS format.

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 17 of the Atlas, Paleographic Evolution of the Western Canada Foreland Basin, Figure 6, Middle Upper Mannville (and Equivalents) Paleogeography. 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.

This lithium ground- and formation-water geochemical dataset will enable present and future companies to better evaluate their targets and characterize their resource estimates by being able to distinguish between background and anomalous concentrations of lithium throughout Alberta. The dataset comprises lithium geochemical data from ground and formation water in Alberta and near the Alberta border. The data were captured from several databases, including those from Alberta Geological Survey (oil and gas wells database, AERI and Beaver River Basin projects), and the Alberta Research Council. In total there are 1,511 records, of which 48 records have >75 mg/L Li. Nineteen analyses have >100 mg/L Li (up to 140 mg/L) and occur within the Middle to Upper Devonian Beaverhill Lake Formation and Woodbend and Winterburn groups of west-central to northwestern Alberta. Economic concentrations of lithium are known to form in either lithium pegmatite or in high-lithium brine and clay. A few of the world's oil-field waters also have medium to high lithium content. During the mid-1990s, several government reports showed that lithium values of up to 140 mg/L Li occurred in west-central Alberta formation waters of the Beaverhill Lake and Woodbend groups. however, minimal data were publicly released.

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.
