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.

Bedrock Topography of Alberta, 1:2,000,000 scale (GIS data, line features)

Description

This dataset is a GIS version of Map 226, which is a regional synthesis of published and unpublished maps. The data represent 100 m elevation contours of the bedrock subcrop for Alberta. The... More ≫

Description

This dataset is a GIS version of Map 226, which is a regional synthesis of published and unpublished maps. The data represent 100 m elevation contours of the bedrock subcrop for Alberta. The southern part of Alberta, from 49 to 56 degrees north, was primarily compiled from existing 1:250,000 bedrock topography maps. The interpretation of the remaining northern portion of Alberta was based mostly on limited borehole data and information from existing 1:250,000 hydrogeological maps.

Description

This dataset is a GIS version of part of Map 227, which is a regional synthesis of various published and unpublished maps. The data represent drift isopachs for Alberta. The southern part of Alberta, from 49 to 56 degrees north, was primarily compiled from existing 1:250,000 bedrock topography maps. The interpretation of the remaining northern portion of the province was based mostly on limited borehole data and information from existing 1:250,000 hydrogeological maps. The exposed areas represent areas where drift is absent or thin and discontinuous. Contour intervals are irregular and depend on local data density.

Alberta Diamond Inclusion Dataset

Description

This Alberta diamond inclusion dataset includes electron microprobe analyses of garnet, clinopyroxene, olivine, ferropericlase and rutile inclusions from diamonds sampled by the Buffalo Head Hills... More ≫

Description

This Alberta diamond inclusion dataset includes electron microprobe analyses of garnet, clinopyroxene, olivine, ferropericlase and rutile inclusions from diamonds sampled by the Buffalo Head Hills kimberlite field. The data are compiled from Davies et al. (2004) and Banas (2006). Diamond inclusions are of particular research interest in diamond exploration and mantle petrology because they provide direct information about the chemical composition of upper and lower mantle and about the petrogenetic sources of diamonds in a given area/deposit.

Description

The first clue to the presence of possible diamond-bearing source rocks in northern Alberta was the discovery of a perfect octahedral diamond, estimated at about 0.83 carats in weight, by farm worker Einar Opdahl during 1958 in the Evansburg area of west-central Alberta. Since the Opdahl diamond, no new diamond finds were reported in northern Alberta until the 1990s, when several occurrences of alluvial diamond and diamondiferous kimberlite were discovered.

Description

This data comprises the polygon features from AGS Map 207, 'Quaternary Geology, Southern Alberta', compiled by I. Shetsen.
