Three four-station chains of Askania Variographs were operated for periods of two months during 1965 and 1966 in British Columbia, New Mexico, Texas, and Oklahoma to form two magnetic depth-sounding profiles, one in western Canada, and the other in the south western U.S.A. Records were also obtained from some I.G.Y. stations and permanent magnetic observatories in the vicinity of the U.S.A. profile. Analyses of the records show that the inland geomagnetic variation anomaly observed by Hyndman (1963) at Kootenay Lake, B.C. reappears to the north between Golden and Johnston Canyon and that the anomaly which Schmucker (p.964) observed between Las Cruces and Cornudas, N.M. reappears to the north between Sayre and Norman, Okla. Power spectral ratios of the form "high-I station / low-I station" suggest that the main features of the subsurface electrical conductivity structures under both the Canadian end the U.S.A. profiles are very similar. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

In my thesis, I compare the short story sequences of Sherwood Anderson's Winesburg, Ohio and John Cheever's The Housebreaker of Shady Hill and Other Stories. Within these texts, I examine the ways in which authors depict the pervasive sense of homelessness and isolation within American communities during the 20th century.

Continental growth may be accomplished at active convergent margins through tectonic accretion and orogeny. Accretionary processes believed to add material to continents include the collision of island arcs and other unsubductable crustal blocks. Using the Intermontane belt as a case study for assessing accretionary processes, it is concluded that island-arc collision and accretion was the principal mechanism for continental growth with relatively minor contributions from 'sliced-off oceanic seamounts and/or plateaux. Fold and thrust belt formation in the northern Intermontane belt records a Middle Jurassic orogenic event that can be attributed to the collision of island-arc highlighting the importance of island-arc collision for causing orogenesis in the North American Cordillera. However, not all orogenic events in the North American Cordillera can be readily attributed to a collisional event. The leading model for driving Laramide orogenesis in the United States is flat-slab subduction, and thermal modelling indicates that subduction of a relatively buoyant oceanic plateau/aseismic ridge may have been responsible for the shallow trajectory. In the Canadian and Mexican portions of the Laramide, the coeval development of a magmatic arc within 300 km of the trench refutes the existence of flat-slab subduction in these regions, and therefore the processes responsible for this orogeny remain enigmatic and require resolution.
