Download or read book The African Erosion Surface written by Kevin Burke and published by Geological Society of America. This book was released on 2008-01-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this Memoir, Burke and Gunnell draw on anglophone and francophone work to analyze the African continent's distinctive basin-and-swell topography. Exploring topics such as landforms, bauxites and laterites, fission-track studies, climatic changes, volcanic rock distribution, hotspots, mantle plumes, and rifts, as well as deep and shallow mantle geophysics, ocean floor evolution, continental flooding, and offshore sediment deposition, the authors have pieced together a coherent, continent-wide reconstruction of landscape development during the past 200 million years. Two episodes of continental breakup and the formation of ocean floor were followed by erosion that reduced the continent to a low-elevation and low-relief African Surface by Late Cretaceous times. Africa's present-day topography developed mostly during the past 30 million years as the African Surface underwent swell uplift and climate changed radically after the Antarctic ice sheet first formed. Northern hemisphere glaciation and related Sahara initiation 3 million years ago were Africa's most recent great changes."--Publisher's website.

Download or read book Geology and Resource Potential of the Congo Basin written by Maarten J. de Wit and published by Springer Science & Business Media. This book was released on 2015-01-02 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the geomorphology, geology, geochronology, geophysics and mineral resources of the Congo Basin, one of the world’s most enigmatic and poorly understood major intra-continental sedimentary basins, and its flanking areas of Central Africa. It provides an up to date analysis of the large region’s origin and evolution. The book’s nineteen chapters take the reader through the entire basement history, as well as the Basin’s ca. 700 million years of cover sequences. Starting from its Archean cratons and Proterozoic mobile belts, and proceeding through the Phanerozoic sequences, including the most recent Cenozoic successions, the book also explores the present drainage systems and the subtle but complex topography of the Congo Basin. It also presents and evaluates new basin models and related dynamic processes, as well as revised correlation schemes with its Gondwana counterparts in South America, all of which provide key insights into its rich diamond deposits and other mineral wealth, which are documented in the final chapters. A specific feature of this book is its synthesis, performed by teams of active experts, of a vast amount of geoscientific data previously only recorded in research reports, company reports, survey bulletins, and scattered journal articles and books. The sheer size of the Congo Basin (ca.1.8 million km2, or just under half the area of the EU) and Central Africa (some 7 million km2, or more than 70% of the area of the USA) will make this a sought-after source of information and inspiration on this unique region.

Book excerpt: The history of science discipline is contributing valuable knowledge of the culture of soil understanding, of the conditions in society that fostered the ideas, and of why they developed in certain ways. This book is about the progressive “footprints made by scientists in the soil. It contains chapters chosen from important topics in the development of soil science, and tells the story of the people and the exciting ideas that contributed to our present understanding of soils. Initiated by discussions within the Soil Science Society of America and the International Union of Soil Sciences, this book uniquely illustrates the significance of soils to our society. It is planned for soils students, for various scientific disciplines, and for members of the public who show an increasing interest in soil. This book allows us to answer the questions: “How do we know what we know about soils? and “How did one step or idea lead to the next one? The chapters are written by an international group of authors, each with special interests, bound together by the central theme of soils and how we came to our present understanding of soils. Each concentrate on soil knowledge in the western world and draw primarily on written accounts available in English and European languages. Academics, graduate students, researchers and practitioners will gain new insights from these studies of how ideas in soil science and understanding of uses of soils developed. * Discusses tracing soils knowledge accumulated from Roman times, first by soil users and after 1800s by scientists* Offers ideas about how soils knowledge was influenced by the social context and by human needs* Combines the history of ideas with scientific knowledge of soils* Written by chapter authors who combine subject matter expertise with knowledge of practical soil uses, and provide numerous references for further study of the relevant literature

Download or read book African Ecology and Human Evolution written by Francis Clark Howell and published by Transaction Publishers. This book was released on 2008 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: The record of man's early evolution, though still fragmentary, is more complete on the African continent than anywhere else in the world. The ecological context of this evolution, however, has been studied intensively only in recent years. This pioneering volume draws together eminent specialists from many fields--physical anthropologists, zoologists, geologists, paleontologists, and prehistorians--who summarize here the results of their diverse research on Pleistocene environments and the cultural and biological evolution of man in Africa. This volume was sponsored by the Wenner-Gren Foundation for Anthropological Research Inc., which met at Burg Wartenstein, Austria. The editors have field experience in Africa, especially eastern and equatorial Africa. This experience is coupled with their awareness of the need to integrate results of numerous field studies bearing on the biological-behavioral evolution of higher primates with other field studies on the paleoecology and the mammalian ecology of sub-Saharan Africa. The book includes contributions on Pleistocene stratigraphy and climatic changes throughout the African continent; on the origin and evolution of the earliest man-like creatures in Africa; on the dating, distribution, and adaptation of Pleistocene hunter-gatherer peoples; and on the ecology, biology, and social behavior of African primate and human populations. The chapters reflect vividly the state of current knowledge at the time and indicate paths for future research. Over 100 maps and figures, detailed bibliographies, and a comprehensive index contribute to the importance of the volume for basic reference use. F. Clark Howell is professor emeritus of paleoanthropology at the University of California, Berkeley where he is co-director of the Laboratory of Human Studies. He is also curator at The University of California Museum of Paleontology. Franois Bourlire (1913-1993) was professor of physiology at the University of Paris. He is also credited with founding the Gerontology Research Unit of Institute of Health and Medical Research and was a member of Paris hospitals.
Download or read book Laterite Soil Engineering written by M Gidigasu and published by Elsevier. This book was released on 2012-12-02 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laterite Soil Engineering is one of a few books about solving engineering problems with the help of engineering pedology. This book presents the latest information on the laterite soils’ geotechnical characteristics and engineering behavior. It shows that laterite soils are different from natural soils and that most laterite soils can be evaluated for engineering purposes using accepted theories and well-known test procedures for temperate-zone soils. This book also shows that modern concepts based on pedological considerations are very useful and take a logical approach to the identification and evaluation of laterite soils for engineering purposes. The first four chapters focus on reviewing information about the processes of tropical weathering and laterization. Chapter five summarizes information about the location, morphology and composition of laterite soils. Chapter six highlights the geotechnical implications of the pedogenic processes of tropical weathering, and it emphasizes the contribution of the results of these pedogenic processes to the deviations of engineering behavior of the problem of laterite soils. In addition, chapter seven discusses the influence of laterite soil genesis on the physic-chemical characteristics based on comparing the properties of three genetic soil groups formed under three different weathering conditions. Chapters eight through nineteen discuss the geotechnical characteristics and evaluation of laterite soils, and the effects of pedogenesis and soil-forming factors on the geotechnical and stabilization characteristics of laterite soils. The last chapter discusses the little information that exists on the application of laterite soils in engineering problems.
