An Evaluation of the Coal Resources of the Ardley Coal Zone, to a Depth of 400 Metres, in the Alberta Plains Area

This report is one product of a coal evaluation program that has been jointly funded by Alberta Energy and Natural Resources and the Alberta Research Council since 1979. Major objectives of the program were: (a) to evaluate the coal resources of the plains region of Alberta south of Township 64, from the near-surface depths of about 400 m; and (b) to develop an understanding of the sedimentologic and stratigraphic controls on the distribution and geometry of the coal seams. The Ardley coal zone is one of the most important coal zones of the plains region and is currently being strip-mined for use in electrical power plants. In this report a comprehensive regional assessment is made of the geological character of coals in the Ardley zone. A description of the calculated inferred resources for the Ardley and other coal zones is presented in a separate report.
