Download or read book The Spanish Coastal Systems written by Juan A. Morales and published by Springer. This book was released on 2018-09-03 with total page 809 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the state of art of the geologic knowledge about the Spanish coast obtained through scientific research in the last 30 years.From a general point of view, coasts are the most quickly changing systems of the Earth. This is critical, since many human resources, such as the main part of economic and social activities, are located in the coastal areas. Especially in the case of Spain these coasts include cities, wide industrial areas (including harbor complexes), important ecologic systems, and our main economic resource: tourism. Understanding the dynamic functioning of each element of this coast is vital for correct future coastal management, so as to solve problems derived from bad plans developed in the last decades of the twentieth century. This is a valuable text for advanced graduate students and coastal researchers, which connects the specific dynamic functioning of the main Spanish coastal environments and their relationships with human activities.

Download or read book Comparative Perspectives on the Archaeology of Coastal South America written by Robyn E. Cutright and published by Center for Comparative Arch. This book was released on 2010 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirteen papers by archaeologists from North and South America on the archaeology of coastal Ecuador, Peru, and Chile. The authors have all emphasized comparative approaches to prehispanic societies along the Pacific coast. They give preference neither to high theory nor to case-specific empirical details, but rather attempt to answer theoretically important research questions with appropriate methodologies and empirical datasets--ones that are amenable to a broad comparative view.

Download or read book Lukurmata written by Marc Bermann and published by Princeton University Press. This book was released on 2014-07-14 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Household archaeology, together with community and regional settlement information, forms the basis for a unique local perspective of Andean prehistory in this study of the evolution of the site of Lukurmata, a pre-Columbian community in highland Bolivia. First established nearly two thousand years ago, Lukurmata grew to be a major ceremonial center in the Tiwanaku state, a polity that dominated the south-central Andes from a.d. 400 to 1200. After the Tiwanaku state collapsed, Lukurmata rapidly declined, becoming once again a small village. In his analysis of a 1300-year-long sequence of house remains at Lukurmata, Marc Bermann traces patterns and changes in the organization of domestic life, household ritual, ties to other communities, and mortuary activities, as well as household adaptations to overarching political and economic trends. Prehistorians have long studied the processes of Andean state formation, expansion, and decline at the regional level, notes Bermann. But only now are we beginning to understand how these changes affected the lives of the residents at individual settlements. Presenting a "view from below" of Andean prehistory based on a remarkably extensive data set, Lukurmata is a rare case study of how prehispanic polities can be understood in new ways if prehistorians integrate the different lines of evidence available to them.

Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

This book was released on 2014-04-24 with total page 1083 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a balance between principles and practice, this state-of-the-art overview of geophysical methods takes readers from the basic physical phenomena, through the acquisition and processing of data, to the creation of geological models of the subsurface and data interpretation to find hidden mineral deposits. Detailed descriptions of all the commonly used geophysical methods are given, including gravity, magnetic, radiometric, electrical, electromagnetic and seismic methods. Each technique is described in a consistent way and without complex mathematics. Emphasising extraction of maximum geological information from geophysical data, the book also explains petrophysics, data modelling and common interpretation pitfalls. Packed with full-colour figures, also available online, the text is supported by selected examples from around the world, including all the major deposit types. Designed for advanced undergraduate and graduate courses in minerals geoscience, this is also a valuable reference for professionals in the mining industry wishing to make greater use of geophysical methods. In 2015, Dentith and Mudge won the ASEG Lindsay Ingall Memorial Award for their combined effort in promoting geophysics to the wider community with the publication of this title.

Download or read book Regions at Risk written by Jeanne X. Kasperson and published by UN. This book was released on 1995 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-induced environmental change is to be found throughout the world, but there are areas that scientists consider to be "critical regions" - regions that are particularly vulnerable to or suffering from environmental degradation. In this volume nine such "critical environmental regions" (Amazonia, the Aral Sea basin, the middle mountains of Nepal, Kenya's Ukambani region, the US Southern High Plains, the Mexico Basin, the North Sea, the Ordos Plateau of China, and the eastern Sundaland region of South-East Asia) are examined as case-studies. In chapter one the authors provide a detailed look into the concepts of environmental criticality and endangerment and propose formal definitions. The nine regional studies that follow in the subsequent chapters serve to translate the conceptual framework into the physical and social realities of each area. The case-studies make available an up-to-date synthesis of vast amounts of inaccessible data, and as such will be valuable to scholars and policy makers interested in specific areas of the world and others interested in regional comparisons. Anyone concerned with global environmental change, criticality, human-environment interactions, and how societies in different regions have responded to environmental degradation will find much that is new and important in this pioneering, innovative study.

Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Download or read book Understanding Mineral Deposits written by Kula Misra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.

Download or read book Techniques in Mineral Exploration written by J.H. Reedman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: For some years I have felt there was a need for a single, comprehen sive, reference book on exploration geology. Numerous textbooks are available on subjects such as geophysical prospecting, exploration geochemistry, mining geology, photogeology and general economic geology, but, for the geologist working in mineral exploration, who does not require a specialist's knowledge, a general book on explora tion techniques is needed. Many undergraduate university courses tend to neglect economic geology and few deal with the more prac tical aspects in any detail. Graduate geologists embarking on a career in economic geology or mineral exploration are therefore often poorly equipped and have to learn a considerable amount 'on the job'. By providing a book that includes material which can be found in some of the standard texts together with a number of practical aspects not to be found elsewhere, I hope that both recent graduates and more experienced exploration geologists will find it a useful reference work and manual. In addition, students of economic geology and personnel working in related fields in the mining and mineral extraction in dustries will find it informative. J. H. REEDMAN v Acknowledgements The author would like to thank Dr K. Fletcher, geochemist with the Department of Geology, University of British Columbia, and Kari Savario, geophysicist with Finnish Technical Aid to Zambia, for reading the original drafts and offering constructive criticism and advice on the chapters on geochemical and geophysical prospecting respectively.

Download or read book The Geology of Ore Deposits written by John M. Guilbert and published by Waveland Press. This book was released on 2007-02-09 with total page 1000 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern civilizations dependence upon an increasing volume and diversity of minerals makes the search for new ore deposits ever more difficult. Now available from Waveland Press, Guilbert & Parks text presents ideas, principles, and data fundamental for beginning economic geologists to understand the genesis and localization of ore deposits and of the minerals associated with them. The authors comprehensively describe the physical and chemical characteristics of ore deposits and correlate them with environments and conditions of deposition, since ore deposits are best interpreted as extensions of the environments responsible for their enclosing rocks. Examples and illustrations emphasize structural, chemical, and temporal controls and encourage the three-dimensional thinking used by productive explorationists as they face unsolved problems. This upper-level undergraduate text is fully illustrated and meticulously indexed. Its reliable, authoritative coverage assumes an upper-level command of chemistry and physics, as well as mineralogy, petrology, and structural geology. Outstanding features . . . develops and combines the abilities of the explorationist and of the researcher of ore-forming processes structures the geologic descriptions into groupings recognized by researchers and explorers alike builds confidence, revitalizes curiosity, and encourages expanded thinking emphasizes that the days of easy discovery of outcropping ores are not over includes revised, expanded, and updated descriptions of districts

Download or read book Human Settlements and Planning for Ecological Sustainability written by Keith Pezzoli and published by MIT Press. This book was released on 2000 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many areas of the world, environmental degradation in and around human settlements is undermining prospects for both socioeconomic justice and ecological sustainability. To explore the issues involved in this worldwide problem, Keith Pezzoli focuses on a dramatic instance of conflict that grew out of the unauthorized penetration of human settlements into the Ajusco greenbelt zone, a vital part of Mexico City's ecological reserve. The heart of the book is the story of what happened when residents of the Ajusco settlements fought relocation by proposing that the areas be transformed into productive ecology settlements. Pezzoli draws upon urban and regional planning theory and practice to examine biophysical as well as ethical and social sides of the story, and he uses the Mexican experience to identify planning strategies to link economy, ecology, and community in sustainable development. -- Publisher description.
