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).

Book Synopsis Antarctica and Supercontinent Evolution by : S.L. Harley
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.
Book Synopsis Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula by : John B. Anderson
Download or read book Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula written by John B. Anderson and published by John Wiley & Sons. This book was released on 2013-05-02 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Special Publications Series. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula presents the analysis of data collected during the SHALDRIL program, which sampled the most complete Cenozoic stratigraphic section in the Antarctic Peninsula. The stratigraphic intervals sampled fill major gaps in the existing stratigraphic record in the region, which is believed to have been the last place in Antarctica to become fully glaciated and, as such, the last refugium for plants and animals living on the continent. Providing previously unpublished results from studies aimed at improving our understanding of the changes in climate, glacial setting, and fauna and flora that took place over the past 30 million years, the volume highlights include discussions of marine seismic and drill core records documenting the initial growth and expansion of an ice sheet across the northernmost Antarctic Peninsula continental shelf in the northwestern Weddell Sea. The book features: Detailed vegetation and phytoplankton evolution from greenhouse through icehouse conditions in Antarctica's last refugium Sand grain texture and micromorphology indicating ice sheet control of weathering style Exhumational history around the Drake Passage margins from thermochronology and sediment provenance Comprehensive review of the opening of the ocean passageway between Antarctica and South America and the associated regional tectonics. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula will be of interest to geologists, climatologists, and glaciologists interested in climate and cryosphere evolution and those factors that regulate it.
Book Synopsis Continents and Supercontinents by : John J. W. Rogers
Download or read book Continents and Supercontinents written by John J. W. Rogers and published by Oxford University Press. This book was released on 2004-09-16 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: To this day, there is a great amount of controversy about where, when and how the so-called supercontinents--Pangea, Godwana, Rodinia, and Columbia--were made and broken. Continents and Supercontinents frames that controversy by giving all the necessary background on how continental crust is formed, modified, and destroyed, and what forces move plates. It also discusses how these processes affect the composition of seawater, climate, and the evolution of life. Rogers and Santosh begin with a survey of plate tectonics, and go on to describe the composition, production, and destruction of continental and oceanic crust, and show that cratons or assemblies of cratons became the first true continents, approximately one billion years after the earliest continental crust evolved. The middle part of the book concentrates on supercontinents, beginning with a discussion of types of orogenic belts, distinguishing those that formed by closure of an ocean basin within the belt and those that formed by intracontinental deformation caused by stresses generated elsewhere. This information permits discrimination between models of supercontinent formation by accretion of numerous small terranes and by reorganization of large old continental blocks. This background leads to a description of the assembly and fragmentation of supercontinents throughout earth history. The record is most difficult to interpret for the oldest supercontinent, Columbia, and also controversial for Rodinia, the next youngest supercontinent. The configurations and pattern of breakup of Gondwana and Pangea are well known, but some aspects of their assembly are unclear. The book also briefly describes the histories of continents after the breakup of Pangea, and discusses how changes in the composition of seawater, climate, and life may have been affected by the sizes and locations of continents and supercontinents.

Book Synopsis Geology and Seismic Stratigraphy of the Antarctic Margin, 2 by : Peter F. Barker
Download or read book Geology and Seismic Stratigraphy of the Antarctic Margin, 2 written by Peter F. Barker and published by Wiley-AGU. This book was released on 1995-01-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dominant feature of the modern Antarctic continent is the ice sheet. It strongly influences global climate, through its effects on sea level, albedo and ocean circulation, and provides a record of climate going back (potentially) about 400,000 years. However, it has existed, in one form or another, certainly for 35 million years and probably for longer. Because of the importance of the ice sheet to climate, now and in the past, a major responsibility of global geoscience has been to unravel its history, and understand the processes that have controlled it.

This book was released on 2011-04-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological Evolution of Antarctica is a collection of papers presented at the Fifth International Symposium on Antarctic Earth Sciences, held under the auspices of the Scientific Committee on Antarctic Research (SCAR) at Robinson College, Cambridge, 23-28 August 1987. Contributors were invited to address problems related to the tectonic evolution of the Antarctic crust and the palaeoenvironmental evolution of Antartica since the Late Mesozoic. One hundred and seventy two papers and posters were presented, of which one hundred and fifteen are included in this volume. Papers dealing with the crustal development of Antarctica are divided into major geographical areas and arranged in chronostratigraphic order. The first four sections in this group cover the craton, the Transantarctic Mountains, Weddell Sea-Ross Sea region and the Pacific margin; the last addresses aspects of Gondwana break-up. A final group of papers discusses some of the environmental changes arising from the break-up of Gondwana.

Book Synopsis Geodynamic Evolution of East Antarctica by : M. Satish-Kumar
Download or read book Geodynamic Evolution of East Antarctica written by M. Satish-Kumar and published by Geological Society of London. This book was released on 2008 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological correlations of East Antarctica with adjoining continents have been puzzling geologists ever since the concept of a Gondwana supercontinent surfaced. Despite the paucity of outcrops because of ice cover, difficulty of access and extreme weather, the past 50 years of Japanese Antarctic Research Expeditions (JARE) has successfully revealed vital elements of the geology of East Antarctica. This volume presents reviews and new research from localities across East Antarctica, especially from Dronning Maud Land to Enderby Land, where the geological record preserves a history that spans the Archaean and Proterozoic. The reviews include extensive bibliographies of results obtained by geologists who participated in the JARE. Comprehensive geological, petrological and geochemical studies, form a platform for future research on the formation and dispersion of Rodinia in the Mesoproterozoic and subsequent assembly of Gondwana in the Neoproterozoic to Early Palaeozoic.
