Download or read book Archean Geodynamics and Environments written by Keith Benn and published by American Geophysical Union. This book was released on 2006-01-10 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 164. The Archean Eon represents 1.3 Gyr of Earth's distant past, from about 3.8 Ga to 2.5 Ga—nearly one third of our planet's history. It was during the Archean that a regime of global geodynamics was established, resulting in the formation and recycling of the first lithosphere, as well as the formation, growth, deformation, differentiation, emergence, and erosion of continents. By the end of the Archean, Earth had reached a geodynamic regime dominated by plate tectonic processes. The consequent environments, at and near Earth's surface, included the different niches within which early life forms evolved. It is to the Archean evolution of Earth that we now look to better understand many of the processes that shaped the planet, as we know it.

Download or read book Evolution of Archean Crust and Early Life written by Yildirim Dilek and published by Springer. This book was released on 2013-11-26 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an integrated approach to the study of the evolution of the Archean lithosphere, biosphere and atmosphere, and as such it is a unique contribution to our understanding of the early Earth and life. The structural and geochemical make-up of both the oceanic and continental crust of the Archean Earth is documented in some case studies of various cratons, and the implications of the Phanerozoic plate and plume tectonic processes for the Archean geology are discussed in several chapters in the book. All chapters are process-oriented and data-rich, and reflect the most recent knowledge and information on the Archean Earth. The interdisciplinary approach of examining the evolution of the Archean crust, oceans, and life that we adopt in this book sets it apart from previous publications on Precambrian geology. The book will be attractive to researchers in academia and in industry, and to senior undergraduate students, graduate students and faculty in earth and natural sciences.

Download or read book Formation and Crust Mantle Geodynamic Processes of the Neoarchean K rich Granitoid Belt in the Southern Range of Eastern Hebei Western Liaoning Provinces North China Craton written by Jinghao Fu and published by Springer Nature. This book was released on 2022-08-23 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meso- to Neoarchean is a critical transitional period for the formation and evolution of continental crust and the corresponding geodynamic mechanisms, during which the average composition of continental crust gradually shifted from Na-enriched to K-enriched. However, the ultimate source of K and its enrichment mechanism in continental crust are still enigmatic. Moreover, fierce controversies remain on the Precambrian subdivision and late Archean geodynamic models of the North China Craton (NCC). Archean basement terranes in the Eastern Hebei-Western Liaoning Provinces, northern NCC display characteristic lithological zonation similar to those developed in modern convergent plate margins, and from northwest to southeast can be subdivided into the MORB-type tholeiite belt, oceanic arc tectonic belt, and K-rich granitoid belt. This book reports systematic field geological, petrographic, structural, whole-rock geochemical, and zircon U-Pb-Hf-O isotopic data for the various late Neoarchean lithological assemblages of the K-rich granitoid belt. Their deformational characteristics and petrogenesis are discussed in detail, and integrated with their spatiotemporal relationships and metamorphic features, a late Neoarchean active continental margin setting with multi-stage trench retreats and subsequent arc-continent collision is proposed to account for the formation and evolution of the K-rich granitoid belt. It also throws light upon the ultimate source and enrichment mechanism of K in the late Archean continental crust by comparing K-rich granitoid belt with the adjacent oceanic arc tectonic belt.

Download or read book Archean Evolution of the Pilbara Craton and Fortescue Basin written by Arthur H. Hickman and published by Springer Nature. This book was released on 2023-03-09 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of today’s major geoscientific controversies centres on the origin of the Archean granite‒greenstone terranes. Is the geology of these scattered remnants of our planet’s early crust consistent with the theory that modern-style plate-tectonic processes operated from the early Archean, or does it indicate that tectonic and magmatic processes were different in the Archean? Earth has clearly evolved since its initial formation, so at what stage did its processes of crustal growth first resemble those of today? The logical place to seek answers to these intriguing and important questions is within the best-preserved early Archean crust. The Pilbara region of northwest Australia is internationally famous for its abundant and exceptionally well-preserved fossil evidence of early life. However, until recently the area has received much less recognition for the key evidence it provides on early Archean crustal evolution. This book presents and interprets this evidence through a new stage-by-stage account of the development of the Pilbara’s geological record between 3.53 and 2.63 Ga. The Archean Pilbara crust represents one fragment of Earth’s oldest known supercontinent Vaalbara, which also included the Kaapvaal Craton of southern Africa. Recognition of Vaalbara expands the background database for both these areas, allowing us to more fully understand each of them.

Download or read book When Did Plate Tectonics Begin on Planet Earth written by Kent C. Condie and published by Geological Society of America. This book was released on 2008-01-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Inspired by a GSA Penrose Conference held in Lander, Wyoming, June 14-18, 2006, this volume discusses the beginning and evolution of plate tectonics on Earth, and gives readers an introduction to some of the uncertainties and controversies related to the evolution of the planet. In the first three sections of the book, which cover isotopic, geochemical, metamorphic, mineralization, and mantle geodynamic constraints, a variety of papers address the question of when "modern-style" plate tectonics began on planet Earth. The next set of papers focuses on the geodynamic or geophysical constraints for the beginning of plate tectonics. The volume's final section synthesizes a broad range of evidence, from planetary analogues and geodynamic modeling, to Earth's preserved geologic record. This work provides an excellent graduate level text summarizing the current state of knowledge and will be of interest to a wide range of earth and planetary scientists."--Publisher's website.

Download or read book Reading the Archive of Earth s Oxygenation written by Victor Melezhik and published by Springer Science & Business Media. This book was released on 2012-09-28 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth’s present-day environments are the outcome of a 4.5 billion year period of evolution reflecting the interaction of global-scale geological and biological processes. Punctuating that evolution were several extraordinary events and episodes that perturbed the entire Earth system and led to the creation of new environmental conditions, sometimes even to fundamental changes in how planet Earth operated. Volume 3: Global Events and the Fennoscandian Arctic Russia - Drilling Earth Project represents another kind of illustrated journey through the early Palaeoproterozoic, provided by syntheses, reviews and summaries of the current state of our understanding of a series of global events that resulted in a fundamental change of the Earth System from an anoxic to an oxic state. The book discusses traces of life, possible causes for the Huronian-age glaciations, addresses radical changes in carbon, sulphur and phosphorus cycles during the Palaeoproterozoic, and provides a comprehensive description and a rich photo-documentation of the early Palaeoproterozoic supergiant, petrified oil-field. Terrestrial environments are characterised through a critical review of available data on weathered and calichified surfaces and travertine deposits. Potential implementation of Ca, Mg, Sr, Fe, Mo, U and Re-Os isotope systems for deciphering Palaeoproterozoic seawater chemistry and a change in the redox-state of water and sedimentary columns are discussed. The volume considers in detail the definition of the oxic atmosphere, possible causes for the oxygen rise, and considers the oxidation of terrestrial environment not as a single event, but a slow-motion process lasting over hundreds of millions of years. Finally, the book provides a roadmap as to how the FAR-DEEP cores may facilitate future interesting science and provide a new foundation for education in earth-science community. Welcome to the illustrative journey through one of the most exciting periods of planet Earth!

Download or read book Encyclopedia of Astrobiology written by Muriel Gargaud and published by Springer Nature. This book was released on 2023-07-27 with total page 3376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in its third edition the Encyclopedia of Astrobiology serves as the key to a common understanding in the extremely interdisciplinary community of astrobiologists. Each new or experienced researcher and graduate student in adjacent fields of astrobiology will appreciate this reference work in the quest to understand the big picture. The carefully selected group of active researchers contributing to this work are aiming to give a comprehensive international perspective on and to accelerate the interdisciplinary advance of astrobiology. The interdisciplinary field of astrobiology constitutes a joint arena where provocative discoveries are coalescing concerning, e.g. the prevalence of exoplanets, the diversity and hardiness of life, and its chances for emergence. Biologists, astrophysicists, (bio)-chemists, geoscientists and space scientists share this exciting mission of revealing the origin and commonality of life in the Universe. With its overview articles and its definitions the Encyclopedia of Astrobiology not only provides a common language and understanding for the members of the different disciplines but also serves for educating a new generation of young astrobiologists who are no longer separated by the jargon of individual scientific disciplines. This new edition offers ~170 new entries. More than half of the existing entries were updated, expanded or supplemented with figures supporting the understanding of the text. Especially in the fields of astrochemistry and terrestrial extremophiles but also in exoplanets and space sciences in general there is a huge body of new results that have been taken into account in this new edition. Because the entries in the Encyclopedia are in alphabetical order without regard for scientific field, this edition includes a section “Astrobiology by Discipline” which lists the entries by scientific field and subfield. This should be particularly helpful to those enquiring about astrobiology, as it illustrates the broad and detailed nature of the field.
