Available in PDF, EPUB and Kindle. Book excerpt: Recent developments have shown that many full and partial ophiolites are preserved in Precambrian cratons. This book provides a comprehensive description and discussion of the field aspects, geochemistry, geochronology and structure of the best of these ophiolites. It also presents syntheses of the characteristics of ophiolites of different ages, and an analysis of what the characteristics of these ophiolites mean for the thermal and chemical evolution of the earth. This title emphasizes new studies of Precambrian Geology that have documented ophiolites, ophiolitic fragments, and ophiolitic melanges in many Precambrian terranes. Each chapter focuses on individual Precambrian ophiolites or regions with numerous Precambrian ophiolites, and covers field aspects, petrology, geochemistry, geochronology, and other descriptive aspects of these ophiolites, it also delves into more theoretical and speculative aspects about the interpretation of the significance of these ancient ophiolites.

Download or read book Archean Crustal Evolution written by K.C. Condie and published by Elsevier. This book was released on 1994-11-11 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of Tectonics/Geochemistry, up-to-date reviews by leading scientists as well as a broad topical coverage of the Archean, are some of the features of this particular volume. As geochronology has progressed in the last 20 years, the Archean has continued to attract interest. Advancements in the understanding of Archean crustal and mantle evolution have progressed rapidly since the first International Archean Symposium in Western Australia (1970). The landmark for the Archean was the NATO Advanced Study Institute at Leicester (1975). At this meeting the Archean truly "came of age". Investigators from many different disciplines focused their expertise on the early history of the earth. For the first time, the nature of the atmosphere, oceans, and life during the Archean was an important part of an Archean symposium. During the most recent Archean Symposium in Perth in 1990, there was a shift in interest from field and trace element data to the new rapidly evolving high-precision U/Pb geochronology of Archean rocks and to detailed structural studies of both low and high grade Archean terrains. The terrane concept so widely applied to the Phanerozoic was proposed for the Archean Yilgarn Province in Western Australia and is now widely accepted for the Archean (as evident by the articles in this book). Plate tectonics is now widely accepted as the principal process that controls the history of continents and oceans. There are, though, well substantiated differences between Archean and post-Archean rocks that indicate that Archean tectonic regimes must have differed in some respects from modern ones. The question of how and to what degree did Archean plate tectonics differ from modern plate tectonics is treated in many of the chapters of this book. Altogether, the editor has presented a selection of articles that provide a fascinating insight into the latest observations in this field.

Download or read book A Tale of Two Cratons written by A. G. Jones and published by Gulf Professional Publishing. This book was released on 2004-03-11 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the established nature of geoscientific knowledge of the Kaapvaal craton compared to the Slave craton, and given the exciting new interdisciplinary results coming from the Kaapvaal Project and from Slave craton studies, scientists working on both cratons were brought together in a workshop to compare and contrast the nature of these two cratons. Of the 54 papers presented at the workshop, 24 are included in this volume. There are clearly major similarities and differences between these two Archean cratons. The crust of both was predominantly formed in the Mesoarchean. Both contain crustal sections consisting of terranes of different ages welded together by Archean accretionary events. Both crustal sections are underlain by lithospheric mantle sections consisting of peridotites that experienced extensive partial melt extraction between 2.9 Ga and 3.2 Ga, but this is where the similarities between the cratons end. One of the most striking differences between the Slave and Kaapvaal cartons is the apparent seismic homogeneity of the Kaapvaal craton's SCLM whereas the Slave craton is seismically layered. The seismic layering in the centre of the craton correlates laterally and with depth with electrical layering and geochemical layering. Taken together, these differences suggest that SCLM formation was different for the two cratons, implying that the search for a single causative formation process is bound to fail. Reprinted from the journal Lithos Volume 71, numbers 2-4.

Download or read book Early Earth Systems written by Hugh R. Rollinson and published by John Wiley & Sons. This book was released on 2009-03-12 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early Earth Systems provides a complete history of the Earth from its beginnings to the end of the Archaean. This journey through the Earth's early history begins with the Earth's origin, then examines the evolution of the mantle, the origin of the continental crust, the origin and evolution of the Earth's atmosphere and oceans, and ends with the origin of life. Looks at the evidence for the Earth's very early differentiation into core, mantle, crust, atmosphere and oceans and how this differentiation saw extreme interactions within the Earth system. Discusses Archaean Earth processes within the framework of the Earth System Science paradigm, providing a qualitative assessment of the principal reservoirs and fluxes in the early Earth. “The book would be perfect for a graduate-level or upper level undergraduate course on the early Earth. It will also serve as a great starting point for researchers in solid-Earth geochemistry who want to know more about the Earth’s early atmosphere and biosphere, and vice versa for low temperature geochemists who want to get a modern overview of the Earth’s interior.” Geological Magazine, 2008

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive compilation of data and ideas relating to the origin, evolution, and significance of the world's greenstone belts, and includes contributions from over 100 experts. In the first of two parts, reviews are presented on broad topics relating to the geology of greenstone belts and their surroundings, covering mainly post-1980 research. These include: historical, sedimentologic, volcanic, structural, metamorphic, metallogenic, and thermal aspects; summaries of mafic/ultramafic magnetism, strain, fluids, geophysics and deep structures; relations with associated granitoids, tectonic evolution, and geochronology; and field relationships. The second part takes a more focused look at the geology of specific cratons and individual greenstone belts worldwide, including Archaean, Proterozoic, and Phanerozoic examples. Detailed geologic maps on large and small scales, extensive tabulations of data, and short written summaries of the salient features are included for all belts. The book will be a valuable reference tool for academic and industrial researchers, students, explorationists, and anyone interested in the evolution of Earth processes over geologic time.
Download or read book Geology s Significant Sites and their Contributions to Geoheritage written by R. M. Clary and published by Geological Society of London. This book was released on 2024-07-23 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions in this book explore several geologically significant sites and, in doing so, acknowledge and explore not just the geological exposures themselves, but also the people and issues that are fundamentally intertwined with the history of our science and its impact on our society. Through selective examples of outcrops and locales integral to the history of geology, we explore the evolution of modern geology, as well as the geodiversity and geoheritage of our planet. While the volume is far from comprehensive, the chapters contained herein detail a range for geoheritage value, scale of geoheritage sites and potential for geoheritage opportunities that will promote a broader, richer understanding of the complexity of the geoheritage of Earth. Importantly, many chapters offer a cautionary tale of sites almost lost to posterity and submit their take-away lessons for community mobilization towards geoheritage site protection.
