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.

Thickness and Distribution of Quaternary and Neogene Sediment in Alberta, Canada (Gridded data, ASCII format)

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.
