The book deals with the most striking landscapes and landforms of Nigeria. Attention is paid to the diversity of geomorphic features found in the country, from the coast to the extreme north, approached geographically at the national, regional and local scales, with a view to highlight the combined influence of geological, climatic, biotic and anthropogenic influences, as well as geoheritage potentials. The topics and sites described range from the mainly depositional coastal lagoons and inlets, the most prominent of which is the oil rich Niger Delta, characterized by the mangrove and rain forest, both of which have been seriously modified by human impact; through the coastal lowlands and associated hill country, with derived, deciduous and dry forest vegetation; the very prominent Niger/Benue Trough and associated features; the savanna-semi desert covered high plains of the north and the Chad Basin, each of which features spectacular landscapes and landforms, including human-made forms such as cities and cityscapes. The book provides the readers with the opportunity to explore the variety of Nigerian landscapes and landforms through informative texts illustrated with color maps and photos: it will be relevant to scientists/scholars as well as others interested in the geology, physical geography, geomorphology, landscape, tourism and other geoheritage-related information about the country.
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 provides a succinct but comprehensive presentation of key geomorphological locations and topics including information about geomorphological heritage and maps to visit the most important sites. Apart from often being remarkably scenic, landscapes reveal stories that often can be traced back in time tens of million years and include unique events. This is particularly true for Ethiopia where spectacular examples of different landforms are present. Its geomorphology varies from highlands, marked by high volcanoes and incised by deep river gorges, to the rift valley lakes endorheic systems and the below sea level lowlands with characteristic landscapes which are unique in the world. Landscapes and Landforms of Ethiopia highlights all these topics including essential information about geology and tectonic framework, past and present climate, hydrology, geographical regions and long-term geomorphological history. It is a highly informative book, providing insight for readers with an interest in geography and geomorphology.
This book presents a beautifully illustrated overview of the most prominent landscapes of South Africa and the distinctive landforms associated with them. It describes the processes, origins and the environmental significance of those landscapes, including their relationships to human activity of the past and present. The sites described in this book include, amongst others, the Blyde River Canyon, Augrabies Falls, Kruger National Park, Kalahari desert landscapes, the Great Escarpment, Sterkfontein caves and karst system, Table Mountain, Cape winelands, coastal dunes, rocky coasts, Boer War battlefield sites, and Vredefort impact structure. Landscapes and Landforms of South Africa provides a new perspective on South Africa’s scenic landscapes by considering their diversity, long and short term histories, and importance for geoconservation and geotourism. This book will be relevant to those interested in the geology, physical geography and history of South Africa, climate change and landscape tourism.
This book describes the Central Sahara region, bringing together an unprecedented combination of diverse and often historic research published in different languages in order to describe its varied landscapes and landforms. The Central Sahara region consists of Libya, Algeria, Mali, Niger and Chad, countries that share similar landscape histories and common landscape traits, including massifs, sand seas, paleowater features and large depressions. Furthermore, human settlement of this region goes hand-in-hand with climate and environmental changes and landscape evolution during the Holocene and earlier; hence, Central Saharan landscapes and landforms provide valuable insights into landscape–human relationships over long timescales. The book offers a comprehensive yet accessible reference source, drawing on both past and present interdisciplinary research and gathering the insights of authors from many different countries to explore a region that has largely been overlooked in available literature.
Outcrops of granitic rocks cover a large proportion of the Earth's surface and host a range of spectacular landforms and landscapes, from extensive plains dotted by inselbergs to deeply dissected mountain ranges. They are often strikingly beautiful, but more importantly, they provide valuable insights into the mechanisms of geomorphic evolution both in the past and at present. The book offers a comprehensive view of the geomorphology of granite areas, examining individual landforms and their assemblages. Weathering processes, and the phenomenon of deep weathering in particular, are given much emphasis as these are fundamental to the understanding of the geomorphic evolution of granite areas. Granite landforms directly related to weathering, such as boulders, tors, inselbergs, and features of surface microrelief are examined in respect to their characteristics and origin. Patterns of slope evolution are shown in the context of both rock slopes and deeply weathered terrains. Granite geomorphology in the coastal, periglacial and glacial context is presented to show how the characteristics of granite control landform evolution in these specific environments. In the closing part a variety of geological controls is reviewed and their primacy over other factors is advocated, followed by an attempt to provide a typology of natural granite landscapes. Finally, certain specific ways of human transformation of granite landscapes are presented. The book will be useful to a range of earth science disciplines, including geomorphology, igneous petrology, engineering geology and soil science. Cultural geographers and people dealing with conservation of geological heritage should find it of interest. Examples from all parts of the world and extensive referencing ensure that it will act as an up-to-date guidebook to the fascinating world of granite geomorphology.
Physical landscapes are one of the most fascinating facets of our Planet, which tell stories about the evolution of the surface of the Earth. This book provides up-to-date information about the geomorphology of the selected ‘classic’ sites from around the world and shows the variety of geomorphological landscapes as moulded by different sets of processes acting over different timescales, from millions of years to days. The volume is written by nearly fifty geomorphologists from more than twenty countries who for many years have researched some of the unique sceneries on the planet. The thirty six chapters present each continent of the world. They describe landscapes of different origin, so that the reader can learn about the complexity of processes behind the sceneries. This is a useful reference book, linking geomorphology with global initiatives focused on nature conservation.
Granite is exposed over more than 15% of the continents, implying that its significance to the Earth’s surface is comparable to that of the carbonates. Landforms and Geology of Granite Terrains is devoted to this phenomenon and provides a comprehensive explanation of the landforms and landscapes developed on granitic rocks and forms. Whereas existing literature in the field predominantly deals with karst landscapes, this book is specifically focussed on granitic terrains. Landforms and Geology of Granite Terrains provides detailed considerations of the forms, major and minor, well-known and not so familiar granitic terrains, developed over large areas of the continents. It comprises interpretations which are of general significance in the analysis and understanding of the landscape and includes many theories in the context of granite landforms. The importance of structure, including crystal stresses, and the value of etching of subsurface initiation, multi-stages or two-stages development, neotectonic forms, solution forms is emphasized as well as the antiquity of some forms and surfaces (inherited forms). Morphogenetic forms are placed in perspective and comparison is made with similar forms in other rock types. This work is intended for geologists, geomorphologists, geographers and mining engineers and can serve both as a practical guide for professionals and as a textbook for university courses. Author, location and subject indices are included.
