Book Description
Written by highly qualified Argentine scientists and scholars, this book focuses on the uninterrupted geological and paleontological record of Patagonia and Tierra del Fuego since the Miocene-Pliocene boundary to the arrival of man and modern times. This region is an outstanding area for research, with significant interest at the international level. It provides an updated overview of the scientific work in all related fields with a strong paleoclimatic approach. Patagonia has also been a sort of a "paleoclimatic bridge" between the Antarctic Peninsula and the more northerly land masses, since the final opening of the Drake Passage in the middle Miocene. Timely and comprehensive, The Late Cenozoic of Patagonia and Tierra del Fuego is the only monograph book written in English.* One-stop resource for paleontological information of the Late Cenozoic of Patagonia* Covers 5 million years in the uninterrupted history of Patagonia and Tierra del Fuego* Comprehensive coverage of the region written by highly qualified Argentine scientists and scholars

Book Description
Ichnology is the science of marks, tracks, trails, traces structures and other sources of evidence of biological activity, beyond the living beings themselves, when studied both in continents and oceans. In spite of its scientific value and interdisciplinary contribution, particularly in South America, in the complex task of identifying ancient environments, information is dispersed and sometimes even ignored. This book has recovered the remarkably abundant information that Ichnology of terrestrial environments has incorporated. The studied geographical regions are the Pampas of Argentina, vast lowlands with a wide latitudinal distribution in between the warm and wet subtropical areas and the cold deserts of Patagonia. Pedogenetic processes preserve tracks and marks found in sediments, rock surfaces and soils, revealing the activity of life forms. This book refers to a variety of signs of biological activity, particularly in ancient soils. This volume includes abundant original information and a meticulous revision of paleo-ichnological investigations, most by the author himself, one of the most important South American specialists, during many decades of his dedication to scientific research. The book includes a review of the stratigraphic sequences of the Cenozoic chronostratigraphic scheme. Firstly, the author provides a scrutiny of the continental ichnofacies and the ichnological record of the South American Cenozoic age. This is followed by chapters dedicated to the faunal associations of vertebrates, with very valuable information about the past climatic events and biogeographical changes, of undoubted value for those scholars interested in vertebrate Paleontology. Likewise, the highly relevant ichnotaxonomy is also developed exhaustively, with special reference to the essential activity of insects in the paleosols, mostly ants and termites. /divFinally, this book presents the most complete, extensive and up-dated bibliography in the subject, which is probably unique as such for southern South America and most of the world. Certainly, this is a book that will provide valuable scientific tools for those specialists interested in this infrequent discipline, either paleontologists, biologists, geologists, pedologists and sedimentologists.

Book Description
This book presents a novel approach in the field of global change by presenting a comprehensive analysis of interhemispheric linkages of climate, present and past, and their effects on human societies. The ultimate goal of this interhemispheric integration is to improve our understanding of causes and mechanisms of climate change to enhance our capability in predicting future changes. Given the societal interest in global change issues this book offers a new approach for the integration of global information. It will provide a reference for professional scientists, researchers and graduate students in the fields of climatology, and the earth and environmental sciences. - Chapters analyse instrumental atmospheric and oceanic data to address such phenomena as El Nino/Southern Oscillation variability and other climate anomalies such as the Pacific and North Atlantic Oscillation and polar air outbreaks - A new systematic methodology is presented that allows objective and verifiable reconstruction of climate fields from sparse data - Especially valuable in the context of climate proxy data

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 Southern Andes, stretching from the subtropics to the subantarctic, are ideally located for palaeoenvironmental research. Over the broad and continuous latitudinal extent of the cordillera (-24˚), vegetation is adjusted to climatic gradients and atmospheric circulation patterns.Opposed to the prevailing Southern Westerlies, the Southern Andes are positioned to receive the brunt of the winds, while biota are set to record the shifting of incoming storm systems over time. Sequential, latitudinally-placed, sedimentary deposits containing microfossils and macroremains, as archives of past vegetation and climate, make possible the detection of equatorward and poleward displacement of plant communities and, as a consequence, changes in climatic controls. No terrestrial setting in the Southern Hemisphere is so unique for palaeoenvironmental reconstruction during and since the last ice age. Twenty radiocarbon-dated fossil pollen and spore records chosen to place emphasis on the last ice age include high-resolution, submillennial data sets that also cover the Holocene, thus providing contrast between present interglacial and past glacial ages. From a refined data base, the records constitute the foundation for interpreting factors responsible for vegetation change over >50,000 14C years, glacial-interglacial migration and refugial patterns for a diversity of taxa, and the extent of intrahemispheric and polar hemispheric synchroneity versus asynchroneity.

Book Description
Improved dating methods have increased our ability to more precisely determine the timing and durations of glaciations. Utilizing glacial and loess deposits, we have compared glaciations that occurred in North and South America in order to determine if events are synchronous or not, to explore forcing mechanisms, and to compare glaciations with cold periods of the Marine Oxygen Isotope stages and the loess/paleosol records of China. Stratigraphic sections containing a variety of glacial deposits, some with interbedded volcanics, as well as loess deposits, were used in reconstructing the glacial history. The Late Pleistocene (Brunhes Chron) Last Glacial Maximum is recognized in mountain and continental areas of North America but only in the mountains of South America. Commonly our comparisons indicate roughly synchronous glaciations on the two continents, whereas other glaciations are more elusive and difficult to compare. Although our comparisons are at low resolutions, the results suggest that Milankovitch forcing is most likely the dominant trigger for hemispheric glaciation modified by local factors.
