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.

Alberta Diamond Occurrences Dataset

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... More ≫

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

All available bathymetry and related information for Fawcett 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

In 2002 the Alberta Geological Survey initiated a project to scan and digitize water well geophysical logs from Alberta Environment and Sustainable Resource Development (ESRD) water well data holdings. Casual and summer student staff scanned hard copy logs systematically by NTS mapsheet starting with the Cold Lake area. Scanned logs were digitized into Log ASCII Standard version 2 by Divestco Ltd. This data release consists of 8,763 LAS files, comprised mostly of resistivity logs, and a tab delimited index file. About 1% of the LAS files also contain a natural gamma log. The API number (APIN) in the log header refers to Alberta Environment's water well identifier number used at the time the logs were digitized. There are 205 records where the API number starts with 900. We were unable to confidently match the log file surface location to an AENV location for these records. The approximate aerial coverage is from latitude 49 degrees to 56 degrees N and from longitude 110 degrees to...

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 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 dataset contains an extract of water chemistry data from the Cold Lake - Beaver River Basin project area. The work was completed in 2004 under contract to Alberta Environment (AENV). Information was obtained from industry and government sources. These data are available in three text files, each representing one table in the original database. See the accompanying jpg of the original relationship diagram to understand how the data in the text files tables are related.
