The Jurassic sediments of the southern Alberta plains, known only from subsurface work, are described as to lithology, thickness, distribution, stratigraphic relationships, and geologic history. The three-fold subdivision of the Ellis group into Swift formation, Rierdon formation, and Sawtooth formation, established in Montana, is recognizable and applicable in Alberta. A major unconformity between the Jurassic beds and the underlying Paleozoic limestone influences the distribution of the Sawtooth formation. Late Jurassic or early Cretaceous erosion truncating the Jurassic formations from south to north has determined the present extent and northern boundaries of these formations in southern Alberta.

Western Canada Sedimentary Basin: A Symposium; Sponsored by the Alberta Society of Petroleum Geologists, and the Saskatchewan Society of Petroleum Geologists
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.
