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...

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.

Burnstick Lake, Alberta - Bathymetry, Digital Elevation Model (Arc ASCII grid format)

Description

All available bathymetry and related information for Burnstick Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar... More ≫

Description

All available bathymetry and related information for Burnstick Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

Description

This GIS dataset depicts the result of a geostatistical model of the bedrock topography in Alberta. This model is based on water-well litholog data, stratigraphic picks made on oil and gas petrophysical logs, data derived from digitized contour interpretations on bedrock topography maps, including bedrock outcrop locations and the 60 m grid-spaced Shuttle Rader Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 550, Bedrock Topography of Alberta, Canada.

Description

This GIS dataset depicts a geostatistical model of the thickness of sediment overlying bedrock in Alberta. The sediment thickness surface was generated to assist the construction of a new geological framework for Alberta. The surface was derived by subtracting the bedrock topography of Alberta (Alberta Geological Survey Map 550) from the 60 m Shuttle Radar Topography Mission digital elevation model. These data comprise the raster surface of Alberta Geological Survey Map 551, Thickness of Quaternary and Neogene Sediment in Alberta, Canada.

Description

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the net-to-gross sandstone ratio distribution within the Paskapoo Formation - Middle Composite Slice of the Sylvan Lake sub-basin. The Middle Composite Slice is one of three distinct geological domains identified in the Paskapoo Formation of the Sylvan Lake sub-basin model. Characterization of net-to-gross sandstone ratio distribution within the Paskapoo Formation provides information about the geological heterogeneity and potential hydraulic connectivity within the formation for input into a groundwater flow model. Alberta Geological Survey (AGS) Open File Report 2014-10 includes a full description of the process used to produce the net-to-gross sandstone ratio grid.
