"This report describes and illustrates two of the important Devonian fossil groups of the Slave Point Formation and Peace Point Member outcropping at Gypsum Cliffs on Peace River in northeastern Alberta. It is based on fossil collections made in 1977 and 1961 and incorporates detailed field observations made in 1956." --

The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.
