Download or read book Manganese Ores of Supergene Zone Geochemistry of Formation written by I.M. Varentsov and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major part of the world's high grade industrial manganese ore is being mined in supergene deposits. This book represents the first attempt to bring together not only academic but also commercial data on all aspects of the geochemistry of formation of supergene manganese ores. It is a distinctive account of the geology, geochemistry, mineralogy, experimental modelling studies, mechanisms of formation processes and geochemical evolution through geological time of manganese ores for all types of supergene deposits. Special emphasis is placed on the general geochemical model of supergene manganese ore formation, which can be applied in geochemical exploration. Despite the fact that supergene manganese ores have been used by mankind since the early centuries, it is only during the last decade that a comprehensive understanding of the nature of geochemical processes of formation of these deposits has become available and their potential as an economic resource has been recognized against other genetical types of manganese accumulations. Audience: This substantial and comprehensive volume is of interest to economic geologists, mining engineers, geochemists, mineralogists and other specialized geoscientists.

Download or read book Treatise on Geochemistry written by and published by Newnes. This book was released on 2013-10-19 with total page 14787 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!
Download or read book Geochemistry of Sedimentary Ore Deposits written by J.B. Maynard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an outgrowth of my interest in the chemistry of sedimentary rocks. In teaching geochemistry, I realized that the best examples for many chemical processes are drawn from the study of ore deposits. Consequently, we initiated a course at The University of Cincinnati entitled "Sedimentary Ore Deposits," which serves as the final quarter course for both our sedimentary petrology and our ore deposits sequence, and this book is based on that teaching experience. Because of my orientation, the treatment given is perhaps more sedimentological than is usually found in books on ore deposits, but I hope that this proves to be an advantage. It will also be obvious that I have drawn heavily on the ideas and techniques of Robert Garrels. A number of people have helped with the creation of this book. I am especially grateful to my students and colleagues at Cincinnati and The Memorial University of Newfoundland for suffering through preliminary versions in my courses. I particularly thank Bill Jenks, Malcolm Annis, and Dave Strong. For help with field work I thank A. Hallam, R. Hiscott, J. Hudson, R. Kepferle, P. O'Kita, A. Robertson, C. Stone, and R. Stevens. I am also deeply indebted to Bob Stevens for many hours of insightful discussion.

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.

Book excerpt: This book presents the second volume of a complete development of the new structural classification of minerals, which is based on the internal crystal structure, and is therefore its natural classification. Because of the large domain of the mineral kingdom, this work is divided into three volumes, in which the minerals are ordered from the structurally simple to the more complex. Audience: This work will be of particular interest to teachers and research workers in mineralogy, and in inorganic crystal structures in academia.
Download or read book The Geochemistry of Manganese and Manganese Nodules in the Ocean written by G.N. Baturin and published by Springer Science & Business Media. 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.
Download or read book Geochemistry of Manganese Oxides a Guide to Sulfide Ore Deposits written by James Arthur Anderson and published by . This book was released on 1964 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geologic and geochemical studies have been made on manganese deposits of known origin in the Tintic mining district, Utah. Chemical and mineralogic characteristics of the supergene manganese oxides can be used to distinguish their source material and therefore their association with sulfide ore deposits. Manganese oxides formed by oxidation of ferroan rhodochrosite halos to massive lead-zinc-silver replacement ore are distinguished by anomalously high amounts of zinc, lead, silver, cadmium, and arsenic. Diagnostic manganese oxide minerals include chalcophanite [(Mc, Zn) Mn2O5·2H2O], hetaerolite (ZnMn2O4), coronadite (PbRO16, R=Mn2Mn4), and todorokite [(Mn, Ca)Mn5O12·3H2O]. Crednerite (CuMn2O4) accompanies these minerals in copper-lead-zinc ore bodies. Manganese oxides formed by oxidation of manganocalcite along conduits remote from sulfide ore are distinguished by a lack of diagnostic minerals and minor element impurities, as well as a deficiency of minor elements and minerals that characterize other deposits. Transported manganese oxides formed by supergene solutions produced by weathering of altered volcanics, or by oxidation of pyritic fissures, are distinguished by anomalously high amounts of sodium, cobalt, nickel, titanium, vanadium, phosphorus, and potassium. They contain one or more of the diagnostic minerals including rancieite [(Ca, Mn)Mn4O9·3H2O], woodruffite [(Zn, Mn)Mn5O12·3H2O], and lithiophorite (Li2Mn2Al8Mn10O35·14H2O. Chemical analyses for zinc, lead, silver, and copper have proven to be a reliable, rapid, and inexpensive field exploration technique for distinguishing manganese oxides associated with sulfide ore in the Tintic mining district. Mineralogic and leach-test confirmations are desirable on samples showing positive results. A review of the literature suggests that similar techniques may be used to distinguish manganese oxides associated with sulfide ore in other mining districts.
