Gondwana Landscapes in southern South America


Book Description

This book presents extensive and new information on the geomorphology of cratonic areas of southern South America. It includes valuable data relating to recurrent controversies in general geomorphology beyond the boundaries of South America and reveals the great need to integrate many different aspects of geomorphology in regional studies. With the focus on ancient landscapes and especially on planation surfaces it addresses the question of what processes could form such huge features, and how they can be preserved for so long. Many of the papers include maps of planation surfaces or other geomorphic units. The volume brings together an up-to-date, state-of-the-art collection of information on South American geomorphology, and shows beyond doubt that geomorphology is on the same time scale as global tectonics, biological evolution and major climate change. Some of the papers describe ancient geomorphological features of areas that have never been studied or published before, while others describe regions which are totally unknown to the public. The scope of the book extends from tropical latitudes north of the Tropic of Capricorn, south to freezing Patagonia in the “roaring fifties”, more than 3,500 km from north to south. Including over one thousand citations from geological and geomorphological literature, this volume will serve as a starting point for a whole new phase of studies of the fascinating landscape history of southern South America.

Marine Isotope Stage 3 in Southern South America, 60 KA B.P.-30 KA B.P.


Book Description

This book presents isotope data reflecting changes in temperature derived from core samples in South America. Marine Isotope Stage (MIS) is examined in detail with respect to Stage 3. With over 20 chapters, this detailed treatise discusses high climatic variability, paleoclimatic events, Dansgaard-Oeschger cycles, continental vertebrates, sea level changes, vegetation and climate changes based on pollen records, and the non-Amazon landscape and fauna from 65 to 20 ka B.P. The book also looks at the earth’s magnetic field and climate change during MIS 3 and MIS 5 and presents a comparison between both stages with respect to marine deposits in Uruguay. With case studies drawn from Brazil, Argentina and Uruguay this book presents research from the some of the worlds experts in this field.




Dynamics of the Pantanal Wetland in South America


Book Description

This book provides readers with in-depth insights into the changes in the Pantanal wetland from its formation to the actual and likely future states. It reveals that today’s Pantanal is an evolutionary consequence of geological, ecological and, more recently, man-made events taking place at distinct space-time intervals. Topics include geotectonics and sun-earth interactions, which largely dictate the rate of drastic changes that eventually disrupt ecological stability and radically rebuild the regional landscape. Furthermore, the biota-climate system is discussed as a major driver reshaping the ecohydrology functioning of the landscape on an intermediate timescale. Also covered are major changes in the landscape ecohydrology and biodiversity due to recent land-use and climate changes induced by humankind in the Anthropocene. The ability to recognize how those temporal scales impact the Pantanal wetland provides the opportunity for wise management approaches and the sustainable development of the region.




Advances in Coastal Geoarchaeology in Latin America


Book Description

This book introduces selected contributions from the GEGAL (Spanish acronym for Latin American Geoarchaeological Studies Group) Workshop held at La Paloma Beach, Uruguay, with a focus on Coastal Geoarchaeology, and an attendance of more than 50 researchers, students and professionals from several Latin American countries. The contributions were selected in order to encompass the vast array of environmental, geomorphological and archaeological contexts comprised in the geographical frame of Latin America. Topics covered through the chapters include specific issues such as human occupation and fluvial dynamic processes in mountain and lowland environments, methodological developments in dating methods, taphonomy and chemical proxies, as well as landscape modification by anthropogenic disturbances. As the first compilation of Coastal Geoarchaeology for Latin America, this book is intended to become a useful tool for students, researchers and professionals from related fields, as it comprises not only the regional state of the art, but also new insights and developments which can be potentially applied to other contexts world wide.




Landforms and Landscape Evolution of the Equatorial Margin of Northeast Brazil


Book Description

More than a simple monograph, the authors present a comprehensive geomorphic overview of a large tropical region where they show how deciphering the long-term landform evolution helps understanding the present set of landscapes and morphodynamic environments. The Equatorial margin of the Brazilian “Nordeste” displays stratigraphic landmarks whose interpretation reveals the age and nature of landforms, leading to a reconstruction of the geomorphic history by the means of combined morphostratigraphic and morphopedological approaches. Beyond the role of differential erosion related to moderate post-oceanic opening uplift, the plain and upland landscape reflects a juxtaposition of landform and soil generations related to a shallow basin inversion, the last stages of which occurred in semi-arid conditions since the Oligocene. These results throw light on old debates on models of long-term landform development in platform areas, and also help evaluating recent models of denudation and burial based on thermochronological methods.

Amazonia: Landscape and Species Evolution


Book Description

The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.

The History of the Study of Landforms or the Development of Geomorphology, Volume 5


Book Description

Co-published with British Society for Geomorphology This volume is the fifth in the definitive series, The History of the Study of Landforms or the Development of Geomorphology. Volume 1 (1964) dealt with contributions to the field up to 1890, Volume 2 (1973) with the concepts and contributions of William Morris Davis and Volume 3 (1991) covered historical and regional themes during the ‘classic’ period of geomorphology (1890–1950). Volume 4 (2008) concentrated on studies of geomorphological processes and Quaternary geomorphology between 1890 and 1965; by the end of this period, process-based studies had become dominant. Volume 5 builds on this platform, covering in detail the revolutionary changes in approach that characterized the study of geomorphology in the second half of the twentieth century. It is divided into three sections: the first deals with changes in approach and method; the second with changes in ideas and the broader scientific context within which geomorphology is studied; and the final section details advances in research on processes and landforms. The volume’s objective is to describe and analyse many of the developments that provide a foundation for the rich and varied subject matter of twenty-first century geomorphology.
