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

A digital grid of the top of the Empress Fm. Unit 1 sand and gravel, (the lowermost unit in the Empress Formation), where present, or the topography of the surrounding landscape, where Unit 1 is absent. The unit is originally modeled from borehole data and adjusted to the bedrock surface and present-day land surface. The grid is generated at a 250 m cell-size resolution, based on information as recent as 2003.
