DOWNLOAD EBOOKThe 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 EBOOKAs 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 EBOOKManganese mineralization is diverse in occurence, origin, mineralogy and geochemistry. This volume includes a review of the range of terrestrial Mn deposits and their relative abundance through geological time. Experimental and modelling approaches to Mn geochemistry and mineralogy can further aid our understanding of the formational and depositational processes involved and thereby our interpretation of deposit metallogenesis.
