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 Ore Geology and Industrial Minerals written by Anthony M. Evans and published by John Wiley & Sons. This book was released on 2013-07-03 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much new data and many new ideas have emerged in the area of oregeology and industrial minerals since publication of the secondedition of this text in 1987. The overriding philosophy behind thisnew edition is the inclusion and integration of this new materialwithin the established framework of the text. The third edition isre-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fullycovered to meet the changing emphasis of courses in appliedgeology. In addition, chapter 1 has been considerably enlarged toinclude a section on mineral economics covering metals, industrialminerals and bulk materials. In this section, the various aspectsof economic exploitation of industrial and bulk materials arecompared with those of metallic deposits. Other major revisions andadditions include a section on fluid inclusions, expansion of thesection on wall rock alteration, expansion of the material onisotope studies, and the inclusion of a section on hydraulicfracturing and seismic pumping.
Download or read book Giant Metallic Deposits written by Peter Laznicka and published by Springer Science & Business Media. This book was released on 2010-09-02 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals in the earth's crust are very unevenly distributed and, traditionally, a small number of ore deposits, districts or countries have dominated the world supply and have influenced commodity prices. The importance of exceptionally large, or rich, deposits has greatly increased in the age of globalization when a small number of international corporations dominate the metals market, based on few very large ore deposits, practically anywhere in the world. Search for giant orebodies thus drives the exploration industry: not only the in-house teams of large internationals, but also hundreds of junior companies hoping to sell their significant discoveries to the "big boys". Geological characteristics of giant metallic deposits and their setting and the politico-economic constraints of access to and exploitation in prospective areas have been a "hot topic" in the past fifteen years, but the knowledge generated and published has been one-sided, scattered and fragmented. This is the first comprehensive book on the subject that provides body of solid facts rather than rapidly changing theories, written by author of the Empirical Metallogeny book series and founder of the Data Metallogenica visual knowledge system on mineral deposits of the world, who has had an almost 40 years long international academic and industrial experience. The book will provide abundant material for comparative research in metallogeny, practical information for the explorationists as to where to look for the "elephants", and some inspiration for commodity investors.

Download or read book Rutley s Elements of Mineralogy written by C.D. Gribble and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rutley's elements of mineralogy has been around for a long time, certainly throughout my own lifetime; and if my great grandfather had read geology, it would have been prescribed reading for him too! It has been rewritten and revised frequently since fir~t conceived by Frank Rutley in the late 19th century. Major revisions occurred in 1902, and then in 1914, when H. H. Read first took over the authorship, and thereafter in 1936 and in 1965 when the last major changes occurred. It was with some trepidation that I agreed to attempt this revision. I had been asked to do it by Janet Watson in 1979, but various commitments delayed my start on it until 1984. This 27th edition encompasses a number of changes. Chapters 1-5 have the same headings as before, but considerable changes have been made in all of them, particularly 1, 3, 4 and 5. Comments sought prior to the revision revealed considerable disagreement about the role of blowpipe analyses in the book. I have only once had blowpipe analyses demon strated to me, and have never used them; but there is no doubt that they are employed in many countries, and many of the tests (flame colour, bead, etc. ) are still useful as rapid indicators of which element is present in a mineral. I have therefore kept blowpipe analysis information in Rutley, but have relegated it to an appendix.

Book excerpt: Minnesota's caves have a deep history. Carver's Cave is the first to be described in the literature of North America after explorer Jonathan Carver visited it in 1766. The storied Fountain Cave was the birthplace of the city of St. Paul. Just after the American Civil War, Chute's Cave inspired an elaborate national hoax regarding an ancient civilization. Folklore surrounds Petrified Indian Cave, where a strangely shaped stalagmite was mistaken for a person turned to stone. Geologist and urban explorer Greg Brick, PhD, uses decades of research to uncover the secrets of geological wonders.
