Book Description
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.

Book Description
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 Description
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 Description
The Proterozoic aeon involved at least three major continental readjustments. India and Antarctica appear in most models of supercontinent reconstructions, but their relative position has been the subject of debate. High-resolution petrological and geochronological data, especially from the Proterozoic mobile belts, provide the principal means of resolving this issue. The ice-covered nature of Antarctica allows only limited access to the rocks, and then only in coastal tracts, so detailed studies in more accessible Proterozoic terrains in India assume added significance. This volume, a follow-up to the XII International Symposium on Antarctic Earth Science, Goa (a SCAR symposium), provides new data from selected locations in east Antarctica (Enderby Land and Dronning Maud Land) and from India, including the Eastern Ghats Mobile Belt (EGMB), Chota Nagpur Gneissic Complex, the Khasi Hills and the Aravalli–Delhi Mobile Belt. The presented geochronological data, constrained by petrological studies, are expected to provide new insights, especially into the EGMB–east Antarctica connection and the rate of continental readjustments in the post-Rodinia break-up.

Book Description
Antarctic Climate Evolution, Second Edition, enhances our understanding of the history of the world's largest ice sheet, and how it responded to and influenced climate change during the Cenozoic. It includes terrestrial and marine geology, sedimentology, glacier geophysics and ship-borne geophysics, coupled with results from numerical ice sheet and climate modeling. The book's content largely mirrors the structure of the Past Antarctic Ice Sheets (PAIS) program (www.scar.org/science/pais), formed to investigate past changes in Antarctica by supporting multidisciplinary global research. This new edition reflects recent advances and is updated with several new chapters, including those covering marine and terrestrial life changes, ice shelves, advances in numerical modeling, and increasing coverage of rates of change. The approach of the PAIS program has led to substantial improvement in our knowledge base of past Antarctic change and our understanding of the factors that have guided its evolution. - Offers an overview of Antarctic climate change, analyzing historical, present-day and future developments - Provides the latest information on subjects ranging from terrestrial and marine geology to sedimentology and glacier geophysics in the context of Antarctic evolution - Fully updated to include expanded coverage of rates of change, advances in numerical modeling, marine and terrestrial life changes, ice shelves, and more

Book Description
The fourth international symposium on Antarctic Earth Sciences took place in Adelaide, South Australia during the week 16-20 August 1982. This volume contains a record of the centenary activities celebrating Sir Douglas Mawson and the one hundred and seventy-four papers that were presented by delegates for discussion over the five days. Sir Douglas Mawson was part of the first team to reach the magnetic South Pole, a leading geologist and scientific figure during the heroic age of of antarctic exploration. The papers presented during the symposium were divided into fifteen categories covering east and west Antarctica, marine, land and glacial geology, plate tectonics, islands, peninsulas, climatic change and Precambrian and Cenozoic era activity. The two hundred persons from sixteen countries who attended the symposium brought together a wide range of the most current expertise and research to share, of which this volume provides a record.
