Download or read book Regional and Specific Deposits written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Strata-Bound and Stratiform Ore Deposits, Volume 9: Regional and Specific Deposits focuses on the processes, methodologies, principles, and approaches involved in the identification of regional and specific ore deposits. The selection first elaborates on the timing of mineralization in stratiform copper deposits, oolitic iron formations, and metalliferous deep-sea sediments. Discussions focus on marine distribution and nature of surface and near-surface deposits, structural setting and associated deposits, principal types of deep-sea metal-enriched sediments, chronological development of oolitic-inland-sea iron formation, and complementary sources and transport mechanisms. The text then tackles heavy-metal accumulation in limnic sediments, trace metals in fresh waters, nature and origin of Archaean strata-bound volcanic associated nickel-iron-copper sulphide deposits, and the significance of pyritic black shales in the genesis of Archean nickel sulphide deposits. Topics include lithological associations, oxidation and supergene alteration of ores, temporal and tectonic setting, dissolved metal concentrations in large freshwater systems, and transport phases of heavy metals in river water. The publication examines strata-bound tin deposits, geology of the Pine Point lead-zinc district, and genesis of the Rammelsberg ore deposit near Goslar/Upper Harz in the Federal Republic of Germany. The selection is a valuable reference for researchers wanting to explore ore deposits.

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 A Geochemical Investigation and Comparison Between Organic rich Black Shales and Mississippi Valley type Pb Zn Ores in the Southern Ozarks Region written by Bryan M Bottoms and published by . This book was released on 2017 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mississippi Valley-type (MVT) deposits are base metal sulfide deposits that are important economic sources of both Pb and Zn, accounting for 24% of the global Pb and Zn reserves. They are found all over the world, often hosted in platform carbonates on the flanks of sedimentary basins, and often in proximity to hydrocarbons. They are epigenetic, not related to igneous activity, and thought to be sourced from low temperature, highly saline basinal brines that are expelled from sedimentary basins during compaction and/or in conjunction with an orogenic event. The basinal lithologies responsible for providing the metals for the ores are still a matter of debate. The ores are highly enriched in radiogenic Pb and thus potential sources must also share this same isotopic signature. Shales have been hypothesized to represent the original source of the metals due to their radioactive nature, the large volumes of connate fluid associated with their sediments before compaction, and their association with hydrocarbons. The Pb isotopic compositions of 20 sphalerite samples from the Northern Arkansas and the Tri-State MVT mining districts, 23 shales from the Chattanooga and Fayetteville formations, and 2 granitic basement rocks from the southern Ozarks have been analyzed and compared in order to evaluate the potential source(s) of the metals. The granites and most of the shales do not match the isotopic signature of the ores and thus may not represent a viable metal source. However, one sample taken from the base of the Chattanooga shale has similar Pb isotopic ratios to the ores, suggesting that the shale may have provided the metals. The depositional environment of the aforementioned shale sample explains the isotopic signature and sheds some light on the origin of the ore deposits.
