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 dataset consists of previously published information from Alberta Geological Survey (AGS) maps and reports, as well as new data for which the quality has been assessed in order to apply a quality-weighting approach prior to modelling the bedrock topography surface. It is the data used to produce AGS Map 602, Bedrock Topography of Alberta. Explanatory notes, references, and data sources appear on a supplementary page to accompany Map 602. These notes describe the distribution of physiographic terrain elements of the bedrock surface across Alberta, and the sources and quality of the data that were used to interpolate this surface.

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...

Compilation of In Situ Stress Data from Alberta and Northeastern British Columbia (tabular data, tab delimited)

Description

This digital dataset is the compilation of an analysis of the in situ stress regime in several regions of Alberta and northeastern British Columbia conducted by Dr. Sebastian Bell under a contract with the Alberta Geological Survey from 1999 to 2004. The dataset includes both new and previously published estimates for vertical stress gradients, minimum horizontal stress gradients, and stress orientation. Understanding the state of stress in the subsurface has always been important in the development of energy resources. The recent development of unconventional oil sand and low permeability hydrocarbon deposits, waste fluid disposal, greenhouse gas sequestration, and potential geothermal energy extraction all require knowledge of the state of stress to operate safely and economically. A lack of understanding of the state of stress in a given project area has the potential to negatively affect the economics of such projects and may expose operators to increased liabilities.

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).

Surficial Geology of the Peerless Lake Area, Alberta (NTS 84B) (GIS data, point features)

Description

This GIS dataset depicts the surficial geology of the NTS map area 84B (point features). The 1:250 000 scale dataset was compiled from four published 1:100 000 scale maps (AGS maps 265, 266, 267... More ≫

Description

This GIS dataset depicts the surficial geology of the NTS map area 84B (point features). The 1:250 000 scale dataset was compiled from four published 1:100 000 scale maps (AGS maps 265, 266, 267 and 267). The aggregated data was generalized by thinning out features where too dense to be represented clearly. The process was overseen by the mapping geologist.The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

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 7 of the Atlas, Paleographic Evolution of the Cratonic Platform - Cambrian to Triassic, Figure 3, Ordovician (OS1) 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.
