Download or read book The Transantarctic Mountains written by Gunter Faure and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.
Download or read book The Ross Orogen of the Transantarctic Mountains written by Edmund Stump and published by Cambridge University Press. This book was released on 1995-03-31 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ross Orogen of the Transantarctic Mountains is the part of the orogenic system that formed at the Pacific continental margin of present-day Antarctica. According to a recent hypothesis, this continental margin was created by the rifting and subsequent drift of Laurentia from Gondwana. With an unparalleled breadth and depth of information, this book provides a detailed synthesis of the history of the Ross orogen. In doing so, it incorporates classical studies with discussions of the most recent and controversial research from the international community. The book also includes a comprehensive bibliography and a historical chronology of all expeditions that have worked on the Ross orogen in the Transantarctic Mountains, from the first sightings by Ross in 1840 right up to the present day. This review of the Ross orogen of the Transantarctic Mountains will be valuable to all geologists interested in these episodes in the Earth's history, and to researchers of the geology of Antarctica.

Available in PDF, EPUB and Kindle. Book excerpt: The study of the Earth’s origin, its composition, the processes that changed and shaped it over time and the fossils preserved in rocks, have occupied enquiring minds from ancient times. The contributions in this volume trace the history of ideas and the research of scholars in a wide range of geological disciplines that have paved the way to our present-day understanding and knowledge of the physical nature of our planet and the diversity of life that inhabited it. To mark the 50th anniversary of the founding of the International Commission on the History of Geology (INHIGEO), the book features contributions that give insights into its establishment and progress. In other sections authors reflect on the value of studying the history of the geosciences and provide accounts of early investigations in fields as diverse as tectonics, volcanology, geomorphology, vertebrate palaeontology and petroleum geology. Other papers discuss the establishment of geological surveys, the contribution of women to geology and biographical sketches of noted scholars in various fields of geoscience.

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).

Download or read book Terrane Processes at the Margins of Gondwana written by Alan Vaughan and published by Geological Society of London. This book was released on 2005 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Australide orogen, the southern hemisphere Neoproterozoic to Mesozoic terrane accretionary orogen that forms the palaeo-Pacific margin of Gondwana, is one of the largest and longest-lived orogens on Earth. This book brings together a series of reviews and multidisciplinary research papers that comprehensively cover the Australides from the Tasman orogen of eastern Australia to the Neoproterozoic and Palaeozoic orogens of South America, taking in New Zealand and Antarctica along the way. It deals with the evolution of the southern Gondwana margin, as it grew during a series of terrane accretion episodes from the late Proterozoic through to final fragmentation in mid-Cretaceous times. Global perspectives are given by comparison with the Palaeozoic northern Gondwana margin and documentation of world-wide terrane accretion episodes in the Late Triassic-Early Jurassic and mid-Cretaceous. The Tasmanides of eastern Australia, and the terrane histories of New Zealand and southern South America are given comprehensive up-to-date reviews.
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.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together many of the world’s leading experts in the fields of Antarctic terrestrial soil ecology, providing a comprehensive and completely up-to-date analysis of the status of Antarctic soil microbiology. Antarctic terrestrial soils represent one of the most extreme environments on Earth. Once thought to be largely sterile, it is now known that these diverse and often specialized extreme habitats harbor a very wide range of different microorganisms. Antarctic soil communities are relatively simple, but not unsophisticated. Recent phylogenetic and microscopic studies have demonstrated that these communities have well established trophic structuring and play a significant role in nutrient cycling in these cold and often dry desert ecosystems. They are surprisingly responsive to change and potentially sensitive to climatic perturbation. Antarctic terrestrial soils also harbor specialized ‘refuge’habitats, where microbial communities develop under (and within) translucent rocks. These cryptic habitats offer unique models for understanding the physical and biological ‘drivers’ of community development, function and evolution.
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 304 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.

Download or read book Antarctic Environments and Resources written by J.D. Hansom and published by Routledge. This book was released on 2014-06-03 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctica is no longer a 'pole apart'. From a scientific perspective, the Antarctic ice sheet, ocean and climate systems are intimately linked with the global climate and are now seen to be of international significance for understanding climate change. From an economic perspective, the Antarctic is perceived to have great potential as a source of marine resources although the extent of speculated mineral and hydrocarbon resources is unknown. From a conservation perspective, the continent of Antarctica represents the ideal image of unspoiled wilderness. Antarctic Environments and Resources is an accessible and timely new geography of the Antarctic which examines the differing and sometimes conflicting interests in the great southern continent, the Southern Ocean and the subantarctic islands against a background of the physical and natural systems of the region and their interactions. It charts the development of human involvement in the area, focusing on the exploitation of resources from early sealing to modern fisheries, tourism and science, and it assesses the consequent impacts on the natural environment. The text also reviews the emerging framework for future environmental management developed under the Antarctic Treaty System. This is an ideal text for undergraduates studying glacial geomorphology, environmental management, polar regions and the Antarctic.

This book was released on 2023-02-14 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Memoir is the first dedicated to the Antarctic mantle. It is a cross-disciplinary reference work combining geochemistry and geophysics to characterize Antarctic mantle properties. Through observations and modelling the mantle structures, compositions and dynamics are characterized at regional and continental scales by subject experts. The Memoir reviews all known occurrences of sub-continental mantle xenoliths in igneous rocks. These studies are presented by region as southern or northern Victoria Land, Marie Byrd Land, the Antarctic Peninsula, East Antarctica and the sub-Antarctic Islands. Sub-oceanic mantle in tectonically emplaced and abyssal settings is also considered where known. This is complemented by a continental-scale mantle xenolith overview, mantle characteristics from igneous rocks and a quantitative mantle fabric study. State-of-the-art, continental-scale geophysical overviews of the Antarctic mantle are presented by discipline as seismology, gravity and magnetics, magnetotellurics, rheology, glacial isostatic adjustment, mantle convection and palaeotopography. This Memoir will be the reference for all researchers interested in the Antarctic mantle and its role in dynamics that shape the Antarctic surface and ice sheets.
