Landforms And Landscape Evolution Of The Equatorial Margin Of Northeast Brazil

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.

This book presents Brazil as a country of continental dimensions. Its territory has a large variety of rock types, geological structures and climates. The country has a large variety of landscapes, such as the humid plains of the Amazon River, the dry plateaus of the semi-arid region or the subtropical mountains of the southern region. On the coast, some plateaus and mountains, like the Serra do Mar Mountain range, formed a significant barrier front to access the hinterland of Brazil. On the other side of these coastal plateaus and mountains, there is a large collection of other plateaus, mountains, plains and depressions little altered by human interference. Thus, Brazil has a unique variety of different landscapes and extraordinary geomorphological sites. The book invites readers to learn more about the beautiful Brazilian landscapes, their complexity and vastness.

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.

This book presents the characteristics and limitations of geological units, Cenozoic and geochronological concepts. It studies landscape aspects developed from research in areas with proved Cenozoic tectonic activity, such as the Potiguar basin, located between the states of Ceara and Rio Grande do Sul in Brazil. The analytical focus involves the relationship between tectonics and landscapes in different scales, in hills or karsts, or regional, in basins, and massifs.

This book presents the Brazilian natural space and environment. It describes the main environmental aspects of Brazil in relation to geology, climate, geomorphology, vegetation, fauna, water resources and environmental issues. The book presents a beautifully illustrated overview of the physical geography of the Amazon Forest, the central Brazilian savannah (Cerrado), the Cocais Forest, the semi-arid area (Caatinga), the Atlantic Forest area, the Pantanal (Brazilian wetlands), the Auraucárias Plateau, the Pampas area (South grasslands) and the Brazilian Coastal Environment (beaches and mangroves).

This book studies the transformation of modern maritimity practices in coastal areas (such as swimming, navigation and tourism) and their implications to the development of Brazilian coastal cities, with an emphasis on the Northeast part of the country. It is a reflection on coastal geography in the tropics and the contemporary valorization of coastal cities from a socioeconomic, technological and symbolical point of view. The book highlights local fluxes on a regional and local scale, showing the incorporation of beach zones to spaces which were previously associated with so called traditional coastal practices (fishing activities and as harboring points). This book is dedicated to geography researchers and students.

This book provides an overview of the tropical marine environments of Brazil and a multi-disciplinary assessment of the impact of ongoing climate change in these environments. These changes will affect physical, biological and biogeochemical characteristics of coastal zones and oceans, modifying their ecological structure, their functions and the various services provided to humans and have the potential of causing severe socioeconomic impacts in local (coastal zone), regional (continental shelf and shallow seas) and global (ocean) scales. The Tropical Brazil presents a unique opportunity to evaluate how spatial and temporal heterogeneity influences the response and resilience of marine environments to climate changes. This region comprises the main reef constructions of the Western South Atlantic Ocean, the majority of the Brazilian deltas, one of the longest mangrove areas of the world, a very narrow and shallow continental shelf, extreme variations in sediment and nutrient flows, as well as undeniable importance in transferring heat and mass between hemispheres.

This book presents the most relevant articles selected from the annals of the symposium. In the last few years, Brazilian Geomorphology has experienced a series of epistemological and methodological innovations expressed by the incorporation of the complexity paradigm, by the progressive break with the climate paradigm, by the emergency role of new theories, and by the advances in methodological fields favored by the adherence to geochronological techniques and in function of the increasingly widespread use of geotechnologies. Furthermore, the Anthropocene/Technogene emerge claims to be more than only a temporal cuts, but as conceptions of a science engaged with social and environmental issues. The National Symposium of Geomorphology, in the maturity of its 13th edition, constitutes a portrait and an important sample of Brazilian geomorphological production, aggregating works carried out in the most diverse types of landscapes of Brazil. The book provides an overview of the current scientific production of Brazilian Geomorphology, highlighting the diversity of landscapes and geoheritage in Brazil, the complexity of the morphogenetic and morphodynamic processes responsible for shaping its surface, and the various abundant methodologies used in geomorphological studies in tropical areas.
