Download or read book Continental Drift written by G. D. Garland and published by University of Toronto Press. This book was released on 1966-12-15 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possibility that the continents of the earth have undergone major changes in position during the earth's history has fascinated scholars for at least three hundred years. Recently, evidence from several scientific disciplines has shown that the possibility must be very seriously considered in any study of the surface features of the earth. The first part of this volume consists of papers given at a symposium on continental drift, held at the annual meeting of the Royal Society of Canada in Charlottetown in June 1964. They present the views of three geophysicists, a botanist, and an astronomer. In these papers, the present evidence for or against continental drift is reviewed and the authors in most cases draw their own conclusions. The reader will find that there is not unanimous agreement in favour of drift. Nearly all discussions of continental drift stress the possible separation of the Americas from Europe and Africa. Considerable work has been done on the tracing of structures, on each side of the Atlantic Ocean, which might once have been connected. Geologists and geophysicists working in the Arctic or on the eastern seaboard of Canada have an important contribution to make to this subject. The second part of this volume, therefore, consists of a group of papers, also presented at the Charlottetown meeting, which throw light on the complicated crustal structure of these regions. In any attempt to reconstruct North America as part of Europe the features described in these papers will have to be taken into account. Once again, the reader will find differences of opinion on the question of whether the evidence favours a separation of our continent from Europe. Indeed, it is because the theory of continental drift us so difficult to confirm without ambiguity by direct observation that it remains controversial but exciting.

Download or read book Appalachian Tectonics written by Thomas H. Clark and published by University of Toronto Press. This book was released on 1967-12-15 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain ranges are the most conspicuous elements of the earth's architecture, and the manner in which the architectural units are arranged or disarranged has become the study of a subdivision of geology known as Tectonics. A hundred years ago James Hall attempted the first scientific synthesis of the steps in the building of the eastern North American mountains, the Appalachians. His initial hypothesis of 1857, expanded and broadened by J.D. Dana during the decade which followed, laid the foundation for our modern geosynclinal theory of mountain building. During the last century of modifications and refinements were contributed concerning the roles played by crustal compression, sub-crustal convection currents, batholiths, metamorphism, gravity sliding, and isostasy. In recent years detailed mapping, supplemented by studies of turbidity currents, paleomagentism, stable isotopes, and radio-activity have helped to unravel the history of mountain building, but today there are as many questions unanswered as there are those for which there are tentative solutions. Aspects of Appalachian orogeny was a suitable subject for the symposium of the Royal Society of Canada Annual Meeting in 1966 at Sherbrooke, Quebec—a city within the Appalachian Mountain System. 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. Such a comprehensive volume, bringing together a variety of points of view of some of the foremost scholars in the field, indicates the vastness of the subject, the significant progress made thus far, the necessity for new and progressive methods of exploration, and above all the interdependence of all the workers in the field, no matter how seemingly unrelated their specialities are.

This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The classical Appalachian, Caledonian, Hercynian, and Mauritanide orogens are now only segments of a once-continuous Paleozoic mountain belt which has been fragmented during Mesozoic-Cenozoic formation of the North Atlantic Ocean. These segments are major parts of the countries surrounding the North Atlantic - most of which are members of NATO. The aim of this NATO conference was to evaluate these fragments in terms of their pre-Mesozoic positions, and to attempt a synthesis of their geologic evolution on an international and orogen-wide scale. Geologists who have studied these scattered remnants have been separated by both geography and discipline. Orogen-wide syntheses have beeen attempted in the past by individuals who are specialists not only in discipline but also in geography; therefore, these attempts have not been satisfactory to everyone. This conference brought together the foremost specialists in different disciplines from each country. They attempted to teach other specialists, not only in their own fields, but in other disciplines, about regional variations and particular problems. The resulting international cross-fertilization, both within and between speciaLties, enriched individual workers and helped to provide a multi-disciplinary overview of the orogen.

Download or read book Geology of the Appalachian—Caledonian Orogen in Canada and Greenland written by Harold Williams and published by Geological Society of America. This book was released on 1995 with total page 951 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the Canadian Appalachian region. The chapter on the East Greenland Caledonides stands alone and there is no attempt to integrate the geological accounts of the two far removed regions. Rocks of the Canadian Appalachian region are described under four broad temporal divisions: lower Paleozoic and older, middle Paleozoic, upper Paleozoic, and Mesozoic. The rocks of these temporal divisions define geographic zones, belts, basins, and graben, respectively. The area is of special interest because so many modern concepts of mountain building are based on Appalachian rocks & structures.
