Notes on the Jurassic of Southwestern Saskatchewan
Four Jurassic formations are recognized in southwestern Saskatchewan—the Watrous, Gravelbourg, Shaunavon, and Vanguard. Since the type sections of these formations were first established, additional drilling has made it advisable to redefine the three members of the Vanguard formation.
The four formations are described briefly and attempts are made to illustrate the correlation between them and the Sawtooth, Rierdon, and Swift formations of the Ellis Group of Montana.
The difficulties experienced in determining the Jurassic-Cretaceous boundary are illustrated by means of several cross sections.
Figures & Tables
As a result of the intensive search for oil and gas in western Canada, a regional meeting was held in 1955. This volume was the result of that meeting, and contains 23 papers divided between a discussion of the Jurassic and a discussion of the Carboniferous. Stratigraphy, subsurface, boundaries, formations, sedimentation and geology of western Canada and adjacent areas are thoroughly covered.
