Jurassic strata of the foothills belt of Alberta and British Columbia have been designated as the Fernie formation after the locality in which they were first recognized. The formation overlies, with erosional unconformity, Triassic or Carboniferous strata and consists of a marine sequence of gray to black shales interbedded with minor amounts of thin sandstones. The upper beds grade through a transition zone into Lower Cretaceous strata which are non-marine and coal-bearing in the southern foothills but vary from non-marine to marine sandstones in the northern foothills. In the latter areas the sandstone sequence contains Jurassic and Lower Cretaceous fossils which suggests the absence of an apparent lithologic or time break between the Jurassic and Cretaceous systems. Fossil evidence from widely separated areas indicates a time range from Sinemurian to Argovian and indicates that the Jurassic seaways were fairly continuous at least in the deeper parts of the Rocky Mountain geo- syncline. This would not necessarily rule out the existence of local uplifts in restricted localities of the area under discussion.

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.
