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 dataset (lineaments_ln_ll.shp) comprises structural features compiled into GIS format from existing literature, published up to 2003. The data represent fault/lineament locations known or inferred in the Alberta Plains. We have chosen to digitize and publish all lineaments from source maps even where they extended beyond the Alberta boundary. Each compiled feature is characterized by a set of attributes including: affected formations (oldest affected and oldest non-affected stratigraphic unit), fault type, fault sense of displacement, evidence used to infer the fault/lineament, original reference information and publication scale, and an estimate of the georeferencing error. The completeness of the captured attribute set varies for each feature as a function of the level of detail in the source article. The data set should be used cautiously. First, the original authors' interpretation of subsurface faults, particularly of 'basement faults', from air photo or satellite imagery...

Description

The bedrock topography map of the Peerless Lake area (NTS 84B) shows the elevation of the bedrock surface. In general, the topography of the land surface reflects the bedrock topography. Thus, bedrock highs underlie the Buffalo Head Hills Upland, Peerless Lake Upland and Utikuma Uplands. Major buried valleys lie within the Loon River Lowland in the west-central part and within the Wabasca Lowlands in the south and northeast parts of the map area. The elevation of the bedrock surface ranges from 780 metres above sea level (masl) in the Buffalo Head Hills to 300 masl in the Loon River Lowland. Segments of three major buried valleys are present: the Muskwa Valley in the south, the Red Earth Valley in the Loon River Lowland and Gods Valley in the northeast. The exact shape of these bedrock valleys and their relationships in the areas where they appear to merge is uncertain as a consequence of the scarcity of relevant drillholes. The Muskwa Valley trends westward towards Lubicon Lake and...

Description

This GIS dataset depicts the surficial geology of the NTS map area 84B (line 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.
