Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.
This comprehensive book contains contributions from specialists who provide a complete status update along with outstanding issues encompassing different topics related to deep-sea mining. Interest in exploration and exploitation of deep-sea minerals is seeing a revival due to diminishing grades and increasing costs of processing of terrestrial minerals as well as availability of several strategic metals in seabed mineral resources; it therefore becomes imperative to take stock of various issues related to deep-sea mining. The authors are experienced scientists and engineers from around the globe developing advanced technologies for mining and metallurgical extraction as well as performing deep sea exploration for several decades. They invite readers to learn about the resource potential of different deep-sea minerals, design considerations and development of mining systems, and the potential environmental impacts of mining in international waters.
This monograph is the most comprehensive treatment available of the geology of the Santa Catalina Mountains north of Tucson, expanding greatly on classic older descriptions of the southern Catalinas. The study treats the entire range with a cross-sectional emphasis to clarify relations among the mylonitic core-complex aspects to the south, passing northward through voluminous Tertiary granitic rocks and an older deformed and metamorphosed zone into a tilted relic of the Plateau. New rock units such as Precambrian glaciomarine deposits are introduced, and the mineral-resource character and potential of each segment of the range is described. The book includes a full-color 1:48,000 geologic map of an 11 x 48 km transect through the range, oriented to permit reconstruction of the jigsaw puzzle produced by Tertiary crustal stretching. Three other detailed maps and descriptions of key localities make the monograph a self-guided tour through the geologic history of the range.
