This book assembles the papers of this symposium, dealing with gravity sliding, studies of sedimentation and structure in limited areas, comparisons with the Appalachians of the United States, the bearing of gravity measurements upon our understanding of mountain structure, earthquakes, and a broad, general view of the tectonic pattern of the earth of which this mountain-built belt is but a small part. The history of mountain building, but today there are as many questions unansweredĪs there are those for which there are tentative solutions.Īppalachian orogeny was a suitable subject for the symposium of the Royal Society ofĬanada Annual Meeting in 1966 at Sherbrooke, Quebec-a city within the Appalachian Mountain System. In recent years detailed mapping, supplemented by studies of turbidityĬurrents, paleomagentism, stable isotopes, and radio-activity have helped to unravel Sub-crustal convection currents, batholiths, metamorphism, gravity sliding, and Refinements were contributed concerning the roles played by crustal compression, During the last century of modifications and Danaĭuring the decade which followed, laid the foundation for our modern geosynclinal His initial hypothesis of 1857, expanded and broadened by J.D. Of the steps in the building of the eastern North American mountains, theĪppalachians.
