Available in PDF, EPUB and Kindle. Book excerpt: Globally growing demand of energy and mineral resources, reliable future projection of climate processes and the protection of coasts to mitigate the threats of disasters and hazards require a comprehensive understanding of the structure, ongoing processes and genesis of the marine geosphere. Beyond the “classical” research fields in marine geology in current time more general concepts have been evolved integrating marine geophysics, hydrography, marine biology, climatology and ecology. As an umbrella the term “marine geosciences” has been broadly accepted for this new complex field of research and the solutions of practical tasks in the marine realm. The “Encyclopedia of Marine Geosciences” comprises the current knowledge in marine geosciences whereby not only basic but also applied and technical sciences are covered. Through this concept a broad scale of users in the field of marine sciences and techniques is addressed from students and scholars in academia to engineers and decision makers in industry and politics.
Download or read book The Indian Ocean Nodule Field written by Ranadhir Mukhopadhyay and published by Elsevier. This book was released on 2007-12-08 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book includes a synthesis of research findings on the structure and evolution of the Central Indian Ocean Basin and its ferromanganese deposits, in particular, on the exploration campaign since 1980s. A comprehensive mixture of recent studies along with classical theories starting from the 1960s is the hallmark of the book. Recent concepts and hypotheses, and also critical appreciation of the state-of-the-art knowledge on nodule formation and resource management are incorporated. After limiting the geographical extension of the nodule field and describing its physiographic, geological, biological, physical and chemical characteristics in chapter 1, the various structural, tectonic and volcanic elements are described in chapters 2 and 3. The bottom sediment characteristics that floor the nodules and crusts are dealt with in chapter 4. The nodules and crusts are described in detail in chapter 5, and their process of formation in the light of variable source material, local and regional tectonic activities, and midplate secondary volcanisms are discussed. The mining, environment, metallurgy, legal and economic aspects of the nodule resources are discussed in chapter 6. This title fulfils the growing need to bring voluminous, but scattered information in the form of a book for easy dissemination to students and researchers.* First dedicated book on the Indian Ocean manganese nodule resources * Comprehensively discusses the dynamics of nodule formation in the Indian Ocean Nodule Field (IONF) * Independently assesses the influence of tectonics and volcanism on the manganese nodule resource potential in local and regional scales
Download or read book Marine Geology and Oceanography of the Pacific Manganese Nodule Province written by James L. Bischoff and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 839 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep-sea manganese nodules, once an obscure scientific curios ity, have, in the brief span of two decades, become a potential mineral resource of major importance. Nodules that cover the sea floor of the tropical North Pacific may represent a vast ore de posit of manganese, nickel, cobalt, and copper. Modern technology has apparently surmounted the incredible problem of recovering nodules in water depths of 5000 meters and the extraction of metals from the complex chemical nodule matrix is a reality. Both the recovery and the extraction appear to be economically feasible. Exploitation of this resource is, however, hindered more by the lack of an international legal structure allowing for recognition of mining sites and exploitation rights, than by any other factor. Often, when a mineral deposit becomes identified as an ex ploitable resource, scientific study burgeons. Interest in the nature and genesis of the deposit increases and much is learned from large scale exploration. The case is self evident for petrol eum and ore deposits on land. The study of manganese nodules is just now entering this phase. What was the esoteric field of a few scientists has become the subject of active exploration and research by most of the industrialized nations. Unfortunately for our general understanding of manganese nodules, exploration results remain largely proprietary. However, scientific study has greatly increased and the results are becoming widely available.

Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Download or read book Handbook of Marine Mineral Deposits written by David Spencer Cronan and published by Routledge. This book was released on 2017-10-19 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook summarizes the main advances in our understanding of marine minerals and concentrates on the deposits of proven economic potential. In cases where our knowledge may be too limited to allow defining of their economic potential, those minerals are covered regionally or by deposit type. Handbook of Marine Mineral Deposits is divided into three sections; Marine placers, manganese nodules and crusts, and deep-sea hydrothermal mineralization. All of these mineral deposits have great potential importance to economic geologists and marine mines. Edited by an acknowledged expert in the field, this handbook includes work by internationally renowned contributors. The new United Nations Law of the Sea, ratified by over 100 countries within the past two years, provides a framework and guidelines for deep-sea mineral exploration that increases international interest in this book. The Handbook serves as a platform from which to launch the more detailed evaluation studies that will need to take place in the 21st century before recovery can continue or commence. Handbook of Marine Mineral Deposits is useful to mineralogists, economic geologists, marine geologists, marine miners, and conservationists. Features

This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manganese nodules were first discovered on the ocean floor 160 miles south-west of the Canary Islands on February 18, 1803, during the first complex oceano logical cruise of the Challenger. They surprised researchers by their unusual shape and also by their unusual chemical composition; nevertheless for many years after wards, they were considered merely as one of Nature's exotic marine tricks. After the Secpnd World War, a comprehensive investigation of the World Ocean started, and new data were obtained on a wide distribution of manganese nodules and their polymetallic composition, that made scientists consider nodules as one of the major characteristics of the deep oceanic zone. Recently, meaning since the 1960's, nodules have been recognized as a potential ore source, investigation of which is stimulated by the progressive depletion of land-based mineral resources. Several generations of scientists from various countries have contributed to the problem of exploration of manganese nodules on the ocean floor. Though the problem has been posed, it has not been solved yet because it required, in its turn, a scrutiny of some fundamental aspects such as composition, nature, accretion r'ate of nodules and retrieval of nodule fields. These problems have been discussed in thousands of papers and larger publications; see, in particulare, Mero, 1965; Horn, 1972; Morgenstein, 1973; Bezrukov, 1976; Glasby, 1977; Bischoff and Piper, 1979; Lalou, 1979; Manganese nodules, 1979; Varentsov, 1980; Cronan, 1980; Manganese nodules . . . , 1984, 1986.
