Download or read book Antarctica and Supercontinent Evolution written by S.L. Harley and published by Geological Society of London. This book was released on 2014-01-24 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica preserves a rock record that spans three and a half billion years of history and has a remarkable story to tell about the evolution of our Earth, from the hottest crustal rocks yet found in an orogenic system, to the assembly and breakup of Gondwana in the Phanerozoic. This volume highlights our improved understanding of the tectonic events that have shaped Antarctica and how these potentially relate to supercontinent assembly and fragmentation. The internal constitution of the East Antarctic Shield is assessed using information available from the basement geology and from detritus preserved as Mesozoic sediments in the Trans Antarctic Mountains. Accretionary orogenesis along the proto-Pacific margin of Antarctica is examined and the volumes of intracrustal melting compared with juvenile magma additions in these complex orogenic systems assessed. This special volume demonstrates the diversity of approaches required to elucidate and understand crustal evolution and evaluate the supercontinent concept.
Download or read book Volcanism in Antarctica 200 Million Years of Subduction Rifting and Continental Break up written by J.L. Smellie and published by Geological Society of London. This book was released on 2021-06-09 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).

This book was released on 2022-07-28 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic's unique environment and position on the globe make it a prime location to gain insights into how Earth and the universe operate. This report assesses National Science Foundation (NSF) progress in addressing three priority research areas identified in a 2015 National Academies report: (1) understanding the linkages between ice sheets and sea-level rise, including both a focus on current rates of ice sheet change and studies of past major ice sheet retreat episodes; (2) understanding biological adaptations to the extreme and changing Antarctic environment; and (3) establishing a next-generation cosmic microwave background (CMB) program, partly located in Antarctica, to study the origins of the universe. NSF has made important progress understanding the impacts of current ice sheet change, particularly through studies focused on the ice sheet and ocean interactions driving ongoing ice mass loss at the Thwaites Glacier and Amundsen Sea region in West Antarctica. Less progress has been made on studies of past major ice sheet retreat episodes. Progress is also strong on CMB research to understand the origins of the universe. Progress has lagged on understanding biological adaptations, in part because of limited community organization and collaboration toward the priority. To accelerate progress during the second half of the initiative, NSF could issue specific calls for proposals, develop strategies to foster collaborations and partnerships, and commission a transparent review of logistical capacity to help illuminate strategies and priorities for addressing resource constraints. Such efforts would also help optimize science and proposal development in an environment of inherently constrained logistics.

Download or read book New Research Opportunities in the Earth Sciences written by National Research Council and published by National Academies Press. This book was released on 2012-04-26 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2001 National Research Council (NRC) report Basic Research Opportunities in Earth Science (BROES) described how basic research in the Earth sciences serves five national imperatives: (1) discovery, use, and conservation of natural resources; (2) characterization and mitigation of natural hazards; (3) geotechnical support of commercial and infrastructure development; (4) stewardship of the environment; and (5) terrestrial surveillance for global security and national defense. This perspective is even more pressing today, and will persist into the future, with ever-growing emphasis. Today's world-with headlines dominated by issues involving fossil fuel and water resources, earthquake and tsunami disasters claiming hundreds of thousands of lives and causing hundreds of billions of dollars in damages, profound environmental changes associated with the evolving climate system, and nuclear weapons proliferation and testing-has many urgent societal issues that need to be informed by sound understanding of the Earth sciences. A national strategy to sustain basic research and training of expertise across the full spectrum of the Earth sciences is motivated by these national imperatives. New Research Opportunities in the Earth Sciences identifies new and emerging research opportunities in the Earth sciences over the next decade, including surface and deep Earth processes and interdisciplinary research with fields such as ocean and atmospheric sciences, biology, engineering, computer science, and social and behavioral sciences. The report also identifies key instrumentation and facilities needed to support these new and emerging research opportunities. The report describes opportunities for increased cooperation in these new and emerging areas between EAR and other government agency programs, industry, and international programs, and suggests new ways that EAR can help train the next generation of Earth scientists, support young investigators, and increase the participation of underrepresented groups in the field.

This book was released on 2013-12-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume highlights developments in our understanding of the palaeogeographical, palaeobiological, palaeoclimatic and cryospheric evolution of Antarctica. It focuses on the sedimentary record from the Devonian to the Quaternary Period. It features tectonic evolution and stratigraphy, as well as processes taking place adjacent to, beneath and beyond the ice-sheet margin, including the continental shelf. The contributions in this volume include several invited review papers, as well as original research papers arising from the International Symposium on Antarctic Earth Sciences in Edinburgh, in July 2011. These papers demonstrate a remarkable diversity of Earth science interests in the Antarctic. Following international trends, there is particular emphasis on the Cenozoic Era, reflecting the increasing emphasis on the documentation and understanding of the past record of ice-sheet fluctuations. Furthermore, Antarctic Earth history is providing us with important information about potential future trends, as the impact of global warming is increasingly felt on the continent and its ocean.
