Ireton Microfossil Zones of Central and Northeastern Alberta

Abstract
The Ire ton shale member of the Woodbend formation in northeastern and central Alberta contains microfossil assemblages of Upper Devonian age that can be used for correlating stratigraphic sections throughout a large portion of the plains area. These fossils can make substantial contributions to both age determination and facies studies, which are of indirect but pertinent value in understanding the geology of this province. Thirty-three of the most commonly occurring species belonging to twenty genera are figured and described. An enormous asymmetric structural and sedimentary basin with the deepest part along the eastern margin of the highly disturbed foothills belt of the Rocky Mountains, the Western Canada sedimentary basin is detailed in this volume. It consists of 30 papers dealing with the petroleum geology of the basin, with most of the papers deal with the area south of the Northwest Territories. The geological history of the area is covered, as well as topics such as: regional stratigraphic analysis, paleontological correlations, structural interpretations, folded faults, and the tar sands of Athabaska River.
