Book Description
This book focuses on the sedimentology of the Hells Kitchen Member of the Port Sussex Formation in East Falkland (Isla Soledad, Las Malvinas). It closely examines two sediment cores spanning these formations that were recovered from the Falkland Islands in 2008 following a mineral exploration programme. The integrated approach of this research, which combines sedimentological data with geochemistry, makes it a robust insight into this past climatic transition and may help to evaluate and inform predictions of future climate change.

Book Description
Understanding the sedimentary and geophysical archive of glaciated margins is a complex task that requires integration and analysis of disparate sedimentological and geophysical data. Their analysis is vital for understanding the dynamics of past ice sheets and how they interact with their neighbouring marine basins, on timescales that cannot be captured by observations of the cryosphere today. As resources, sediments deposited on the inner margins of glaciated shelves also exhibit resource potential where more sand-dominated systems occur, acting as reservoirs for both hydrocarbons and water. This book surveys the full gamut of glaciated margins, from deep time (Neoproterozoic, Ordovician and Carboniferous–Permian) to modern high-latitude margins in Canada and Antarctica. This collection of papers is the first attempt to deliberately do this, allowing not only the similarities and differences between modern and ancient glaciated margins to be explored, but also the wide spectrum of their mechanisms of investigation to be probed. Together, these papers offer a high-resolution, spatially and temporally diverse blueprint of the depositional processes, ice sheet dynamics, and basin architectures of the world’s former glaciated margins; a vital resource in advancing understanding of our present and future marine-terminating ice sheet margins.

Book Description
A complete and updated catalogue of impact craters and structures in South America from 2014 is presented here. Approximately eighty proven, suspected and disproven structures have been identified by several sources in this continent. All the impact sites of this large continent have been exhaustively reviewed: the proved ones, the possible ones and some very doubtful. Many sites remain without a clear geological "in situ" confirmation and some of them could be even rejected. Argentina and Brazil are leading the list containing almost everything detected. In Bolivia, Chile, Colombia, Guyana, Paraguay, Perú, Uruguay and Venezuela only a few were observed. Only Ecuador is waiting for new discoveries. So far, the largest well stated impact site is still the Araguainha structure in Brazil with its 40 kilometers in diameter. However, two possible impact structures are larger than Araguainha: Malvinas, (with 250 kilometers in diameter) and Vichada in Colombia, (50 kilometers). This study also reports the existence of some Tertiary-Quaternary glassy impactite layers: the "escorias" and "tierras cocidas" of the pampas in Argentina.

Book Description
For most people, planet Earth's icy parts remain out of sight and out of mind. Yet it is the melting of ice that will both raise sea level and warm the climate further by reducing the white surfaces that reflect solar energy back into space. In effect, our icy places act as the world's refrigerator, helping to keep our climate relatively cool. The Icy Planet lays out carbon dioxide's role as the control knob of our climate over the past 1000 million years, then explores what is happening to ice and snow in Antarctica, the Arctic and the high mountains. Colin P. Summerhayes takes readers to the world's icy places to see what is happening to its ice, snow, and permafrost. He recounts tales from his own visits to these frozen landscapes, shining a light on some of the wonders he has encountered in his travels. He also brings together pieces of the climate story from different scientific disciplines, and from the past and the present, to illustrate how Earth's climate system works. Utilizing geological records of climate change alongside new technologies in ice coring, Summerhayes crafts a detailed and compelling record of Earth's climate history and examines how that can be used as a window into our future.

Book Description
This book of contributed papers reconstructs events following the major Paleozoic glaciation, using as analog events during the last 18,000 years. The detailed analysis of present environments aids in understanding what triggered the ancient deglaciations; conversely, the study of the ancient geological record helps to identify factors that influence global environmental change. The syntheses and analyses of Quaternary and older glacial products and events foster a better understanding of those periods in which rapid climatic and environmental changes occurred, and they constitute a ready source of information for analyzing other ancient geological records or constructing models for possible future changes.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 50. The concept of “accreted terranes,” that continents grow by the addition of displaced fragments of crust, was the central topic of a recent multidisciplinary symposium sponsored by the International Union of Geodesy and Geophysics (IUGG). This volume contains a selection of papers presented in Symposium 12 at XIX General Assembly of the IUGG, held August 15–18, 1987, in Vancouver. Convenors Edward Irving and David Stone focused the program on two major themes. The first was to track the displacement of terranes using paleomagnetism, geologic mapping, and paleontology. The second theme was to explore the deep structure of accreted terranes using seismological, geochemical, and potential-field methods. Given the scope of those topics, it is no surprise that the participants represented many specialties within the field of solid-earth geophysics. The program included case histories from a collection of fold belts spanning much time and long distances, from the Proterozoic sutures of North America to the Cenozoic accretionary complexes of the Pacific rim.

Book Description
Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.

Book Description
The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the paleoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic paleobotany and terrestrial paleoecology.
