Download or read book Paleomagnetism written by Michael W. McElhinny and published by Elsevier. This book was released on 1999-10-18 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleomagnetism is the study of the fossil magnetism in rocks. It has been paramount in determining that the continents have drifted over the surface of the Earth throughout geological time. The fossil magnetism preserved in the ocean floor has demonstrated how continental drift takes place through the process of sea-floor spreading. The methods and techniques used in paleomagnetic studies of continental rocks and of the ocean floor are described and then applied to determining horizontal movements of the Earth's crust over geological time. An up-to-date review of global paleomagnetic data enables 1000 million years of Earth history to be summarized in terms of the drift of the major crustal blocks over the surface of the Earth. The first edition of McElhinny's book was heralded as a "classic and definitive text." It thoroughly discussed the theory of geomagnetism, the geologic reversals of the Earth's magnetic field, and the shifting of magnetic poles. In the 25 years since the highly successful first edition of Palaeomagnetism and Plate Tectonics (Cambridge, 1973) the many advances in the concepts, methodology, and insights into paleomagnetism warrant this new treatment. This completely updated and revised edition of Paleomagnetism: Continents and Oceans will be a welcome resource for a broad audience of earth scientists as well as laypeople curious about magnetism, paleogeography, geology, and plate tectonics. Because the book is intended for a wide audience of geologists, geophysicists, and oceanographers, it balances the mathematical and descriptive aspects of each topic. Details the theory and methodology of rock magnetism, with particular emphasis on intrepreting crustal movements from continental and oceanic measurements Outlines Earth history for the past 1000 million years, from the Rodinia super-continent through its breakup and the formation of Gondwana to the formation and breakup of Pangea and the amalgamation of Eurasia Provides a comprehensive treatment of oceanic paleomagnetism Provides a set of color pateogeographic maps covering the past 250 million years Written by two internationally recognized experts in the field

Download or read book Stratigraphy written by Jacques Rey and published by Editions TECHNIP. This book was released on 2008 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, written by 33 stratigraphic experts, presents various processes available which will enable the location in time of all rock types: sedimentary, metamorphic, plutonic, and eruptive, whether they are in outcrop or at subsurface. The terminology and the appropriate practices for each method are presented in separate chapters and illustrated with concrete examples. The order of the chapters is modeled on the progression of the stratigraphic process, from the descriptive to the interpretative, from the methods of the geometric stratigraphy (lithostratigraphy and genetic stratigraphy, chemostratigraphy, magnetostratigraphy) to the chronological stratigraphy (biostratigraphy), followed by the chronometric stratigraphy (isotopic geochronology). The final two chapters are dedicated to chronostratigraphic units and correlations which combine the contributions of various methods and to the presentation of the 2007 version of the Geological Time Scale. The definitions of stratigraphic terms can be found in a glossary at the end of the work. The book is addressed to all professional geologists, from the industrial sector as well as those in universities, including teachers and researchers who would like to deepen their knowledge of the vocabulary, the concepts, the methods and the practical applications of different approaches of stratigraphy, a reference discipline for the entirety of the geological sciences.
Download or read book Paleomagnetism of the Early Proterozoic Sioux Quartzite Southwestern Minnesota implications for Correlating Quartzites of the Baraboo Interval written by Val W. Chandler and published by . This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleomagnetic studies were conducted on the Early Proterozoic Sioux Quartzite, one of the so-called "Baraboo interval" red-bed sequences of the Lake Superior region. A total of 158 samples were collected from 17 sites scattered across four basins (Cottonwood County, New Ulm, northern Pipestone, and southern Pipestone) in southwestern Minnesota. Alternating-field and thermal demagnetization studies indicate that the magnetization is dominantly single component, and that the magnetic carrier is hematite. Hematite occurs both as a diagenetic mineral whose long paragenetic history began shortly after deposition and as veinlets that formed during a strain event possibly related to regional tilting. The magnetization is tentatively interpreted to have occurred before regional tilting, although a definitive fold test is difficult because dips are low. Measured paleomagnetic directions at both site and basin levels show good clustering, and the average directions obtained from each of the four basins are not significantly different at the 95 percent confidence level. The good clustering at all levels of sampling indicates that the Sioux Quartzite was magnetized either within a short time interval or during a period of subdued apparent polar wander. The structurally corrected paleomagnetic directions from the four basins yield a combined paleopole location at 1 01 ° W. and 16° N. (k=65, alpha 95=11 °). Dated paleopoles for Early Proterozoic rocks in North America and age dates of rocks interpreted to underlie the Sioux Quartzite imply that its age is 1,700-1,650 Ma. This interval corresponds in part with the age of 1,800-1,630 Ma of the Central Plains orogen, which lies some 200-300 kilometers south of the Sioux Quartzite out- crop. Quartzite may reflect a tectonic pulse related to the Central Plains orogen. Preliminary paleomagnetic data on Baraboo-interval quartzites from Wisconsin indicate that the Sioux paleopole cannot be distinguished at the 95 percent confidence level from that of the Barren Quartzite, but that it differs from that of the Baraboo Quartzite, which on the basis of existing apparent polar wander data could be as much as 100 million years older. The paleomagnetic data support previously raised cautions that some Baraboo interval quartz arenites may have been deposited in separate basins at significantly different times.

Download or read book Paleomagnetic Rotations and Continental Deformation written by Catherine Kissel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most interesting results obtained in the last two decades in the study of crustal deformation has been the recognition that large regions of continental crust undergo rotations about vertical axis during deformation. Proof of such rotations has come through the paleomagnetic studies, which reveal rotations when paleomagnetic declinations within the deforming region arc compared with those found in coeval rocks in the stable regions outside the deforming zone. Such rotations were first described in Oregon then in the North American Cordilleras and in Southern California and were a surprise to everyone. Even in California which, as a result of oil exploration, was among the best geologically explored regions in the world, no one could claim to have predicted that these rotations would be found. Rotations have subsequently been found in other areas of recent continental tectonic activity, notably in the Basin and Range province, New Zealand, the Andes, Greece and Western Turkey, so that they appear as an important feature of continental deformation.
Download or read book The Continental Drift Controversy Volume 2 Paleomagnetism and Confirmation of Drift written by Henry R. Frankel and published by Cambridge University Press. This book was released on 2012-04-26 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resolution of the sixty-year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth science. This four-volume treatise on the continental drift controversy is the first complete history of the origin, debate and gradual acceptance of this revolutionary theory. Based on extensive interviews, archival papers and original works, Frankel weaves together the lives and work of the scientists involved, producing an accessible narrative for scientists and non-scientists alike. This second volume provides the first extensive account of the growing paleomagnetic case for continental drift in the 1950s and the development of apparent polar wander paths that showed how the continents had changed their positions relative to one another, more or less as Wegener had proposed. Paleomagnetism offered the first physical measure that continental drift had occurred and helped determine the changing latitudes of the continents through geologic time.
