Available in PDF, EPUB and Kindle. Book excerpt: Understanding Ethiopia is a detailed description of Ethiopia’s geological story and enables non-specialist readers to share the author’s thrill at gaining a deeper insight into the processes which produced, and continue to shape, this amazing country. Ethiopia’s spectacular landscapes, ranging from mountains over 4500m high to salt plains 150m below sea level, are a reflection of the geological processes that formed the country. Indeed, its history and the historical sites, for which it is renowned, are largely determined by geology. Readers learn why and how Ethiopia’s geology is both unique and dynamic, as here the earth’s crust is in the process of breaking apart.

Download or read book Landscapes and Landforms of Ethiopia written by Paolo Billi and published by Springer. This book was released on 2015-03-23 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Geology of Afar East Africa written by Jacques Varet and published by Springer. This book was released on 2017-11-14 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the geological knowledge accumulated on Afar in the last 60 years, demonstrating that it is, and will remain, a real “hot spot” for geological and geophysical research. It provides insights into the Earth processes along diverging plate boundaries, the study of both the continental and oceanic lithosphere and underlying asthenosphere, and margins and transitions including magmatic, volcanic, tectonic, sedimentary, hydrothermal and geodynamic processes. The Afar triangle is a geological depression that developed where the Gulf of Aden, Red Sea and East African Rift Valley meet. It is considered to be one of the Earth system’s most important mantle plumes. In 1967, when the first expedition was organized, there was little information on the geology of the area, and even geographic base maps were lacking. However, the first satellite photographs from the Apollo and Gemini space missions offered a complete picture of the Red Sea-Gulf of Aden region, providing a new vision of the Afar triangle. The book describes the unique geological features that make Afar the only place in the world where an oceanic plate boundary with all its successive steps of development can be observed in the open air. It also presents the Afar triangle as one of the cradles of first, now extinct hominids. The Middle Awash area contains sites of several fossil discoveries, such as the well-known Lucy. The hydrothermal processes in Afar provide conditions suitable for the study of the most primitive forms of life (archaebacterial) and it is also one of the few places where significant quantities of telluric energy are available at the surface for geothermal development. Further, the area has economically interesting mineral deposits and illustrates a number of current climate change issues. In addition to providing geological information, the book shows that Afar is an area where an individual human population developed with its own language and culture, and which adapted to the rugged landscape and extremely dry and hot climate. It is a valuable resource for scientists and students, and also serves the needs of the Afar nation, currently split in three different countries as a result of recent historical events.
Download or read book Groundwater in Ethiopia written by Seifu Kebede and published by Springer Science & Business Media. This book was released on 2012-08-01 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive description of groundwater resources in Ethiopia and its various dimensions (groundwater as resource, environmental functions, and socioeconomics). The prevailing knowledge of groundwater resources in Ethiopia (or elsewhere in Sub Saharan Africa) was based on geological and stratigraphic framework known nearly four decades ago (mainly 1960's and 70's). Thanks to the substantial geoscientific research since the 70's a new set of relevant geological/stratigrahpic data has been created that helps to re-define our understanding of groundwater resources in Africa as a whole and in Ethiopia in particular: a) For the first time the basement aquifer of Ethiopia has been described hydrogeologically based on genesis of regoliths (deep weathering and striping history); clear regional difference in groundwater potential is shown for the first time; comparative accounty has been given regarding groundwater occurrence in the generally low grade basement rocks of Ethiopia (Arabian Nubian shield) and high grade basement rocks of the rest of Africa. b) For the first time groundwater occurrence in multilayred sedimentary rocks account for spatial variation in degree of karstification; deformation history, and stratigraphy. c) The vast volcanic aquifers of Ethiopia which have previously classified based on their ages are now reclassified based on age, morphology (eg. groundwater in plateau volcanics, groundwater in shield volcanics) and aquifer structure. d) The loose alluvio lacustrine sediments which were known as least extensive in previous works based on areal cover are in fact shown to host the most voluminous groundwater resources in Ethiopia. These aquifers have now been described based on their geomorphology, extent, and genesis. The aim of this book is to use these newly created knowledge to redefine the understanding of groundwater resources in Ethiopia.
Download or read book Geology of Hungary written by Janós Haas and published by Springer Science & Business Media. This book was released on 2012-06-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hungary lies in the central part of the Pannonian Basin, surrounded by the ranges of the Alps, Carpathians, and Dinarides. The geology of the country can be summarized as a process whereby complicated plate collision-type orogeny was followed by the formation of a young basin in which a relatively complete sequence of basin infill has been preserved. The handbook “Geology of Hungary” presents an outline of the main features of the geology and geohistory of the region in a single volume, illustrated by a great number of color figures and photos for the benefit of foreign geoscientists interested in this area. The volume follows the evolutionary history of the major structural units prior to their juxtaposition in the Tertiary and discusses the subsequent evolution of the Pannonian Basin. Due to the geohistorical approach to this study it was necessary to extend the scope of the discussion beyond the present-day political boundaries of Hungary, to cover most of the Pannonian region.

Download or read book Homo erectus written by W. Henry Gilbert and published by Univ of California Press. This book was released on 2009-02-04 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the first in a series devoted to the paleoanthropological resources of the Middle Awash Valley of Ethiopia, studies Homo erectus, a close relative of Homo sapiens. Written by a team of highly regarded scholars, this book provides the first detailed descriptions, photographs, and analysis of the fossil vertebrates—from elephants and hyenas to humans—from the Daka Member of the Bouri Formation of the Afar, a place renowned for an abundant and lengthy record of human ancestors. These fossils contribute to our understanding human evolution, and the associated fauna provide new information about the distribution and variability of Pleistocene mammals in eastern Africa. The contributors are all active researchers who worked on the paleontology and geology of these unique deposits. Here they have combined their disparate efforts into a single volume, making the original research results accessible to both the specialist and the general reader. The volume synthesizes environmental backdrop and anatomical detail to open an unparalleled window on the African Pleistocene and its inhabitants.
Download or read book Geo trekking in Ethiopia s Tropical Mountains written by Jan Nyssen and published by Springer. This book was released on 2019-07-09 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on over 150 scientific papers about the Dogu’a Tembien district in Ethiopia. To reach a broader public of people interested in geosites and human-environment interactions, the authors here add a geoguide about this mountain district in Ethiopia(13°30’ N, 39°10’ E; upto 2850 m high) which shows a varied lithology. A large team has carried out research in that district over the past 23 years, including long stays in the areas. Numerous viewpoints and geosites are only accessible on foot; hence the authors prepared the book as a trekking guide, which will enhance sustainable tourism in the same time. This edited work summarises the study results in the international literature into a comprehensive book, which comprises 35 thematic chapters, detailed description of 573 km of trekking routes to access the landscape and the most scenic excursion points, as well as the necessary logistical information. A state-of-the-art trekking map is included as a digital annex.

Book excerpt: "What if the very country that claims the Cradle of Humanity is also the next Mecca for adventure: In March of 2007, four women traveled to northern Ethiopia to climb virgin sandstone towers in the Horn of Africa. They explored rock monoliths in a region that is best known for the drought and famine of the 1980s and was the site of one of the bloodiest massacres of the Derg. Vertical Ethiopia is the narrative of their journey. Told through a series of vignettes that reveal what it means to climb, to travel, and to explore, Vertical Ethiopia looks closely at the intersections between adventure and culture, history and opportunity, and sky and sandstone"--Amazon.
Download or read book Adventures in the Bone Trade written by Jon Kalb and published by Springer Science & Business Media. This book was released on 2000-10-27 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: As co-founder of the expedition that discovered Lucy, and leader of most of the first site-surveys in the Afar Depression in Ethiopia, Jon Kalb has years of experience with the region, its politics, and the scientists involved in the excavations. A participant himself in the "bone wars" that accompanied these discoveries, Kalb recounts the cutthroat competition and back stabbing that were often part of the media-highlighted race to find the oldest hominid fossil. He weaves this story in the rich fabric of Ethiopian society and politics, the plight of the regions peoples, and the international maneuverings for control of the fossil finds.
