This book was released on 2019-11-14 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book (Special Issue) presents impressive new results related to a wide spectrum of occurrences of platinum-group minerals (PGM) and natural compounds enriched in platinum-group elements (PGE), which are associated with various complexes and deposits, such as Uralian-Alaskan-type complexes, layered intrusions and placers. The geographical locations of the involved deposits and complexes include, on a truly international scale, different areas of the Urals, Western and Eastern Sayans and Gornaya Shoria in Siberia, Southern Central Asian Orogenic Belt in China, Northern Michigan, USA, South Africa and Zimbabwe, etc. Of particular interest is the first description of a new species of PGM, thalhammerite (approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association), which is a new species of palladium-silver sulfobismuthide discovered in the Noril’sk region of Russia. Additionally, comprehensive reviews, on compositional variations in Pt–Fe alloy minerals and processes of transformations of PGM in exogenic environments, are presented which will also attract attention from international readers.

Download or read book Large Igneous Provinces and their Plumbing Systems written by R. K. Srivastava and published by Geological Society of London. This book was released on 2022-03-15 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identification of large-volume, short-duration mafic magmatic events of intraplate affinity in both continental and oceanic settings on the Earth and other planets provides invaluable clues for understanding several vital geological issues of current concern. Of particular importance is understanding the assembly and dispersal of supercontinents through Earth’s history, dramatic climate change events including mass extinctions, and processes that have produced a wide range of large igneous province (LIP)-related resources, such as Ni–Cu–PGE, Au, U, base metals and petroleum. This volume comprises 21 contributions on the latest developments and new information on LIPs and their plumbing systems and presents methodical studies on different components of LIP plumbing systems. These articles are especially helpful in understanding continental break-up events, regional domal uplift and a variety of metallogenic systems, as well as the temporal and spatial distribution of LIPs, their origin and their likely links to mantle plumes/superplumes.
Download or read book Ancient Earth and the First Ancestors A Cultural and Geological Journey written by Ron Morton and published by Rockflower Press LLC. This book was released on 2011-11-30 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this sequel to the award winning Talking Rocks an earth scientist and an Ojibwe elder travel across Minnesota exploring the ancient rocks that make up a large part of that state.As the geologist describes how these rocks formed and brings to life the ancient worlds they created, the elder, through Native American stories, oral history, culture, and science illustrates how his people had an intimate understanding of,and respect for, these ancient rocks and the land they gave shape to.Traveling from Ely, Grand Portage, Gunflint Lake, and Isle Royale in the northern part of the state south to Jeffers, Mor¬ton, and Blue Mounds State Park the two find themselves discussing such diverse topics as the nature of science, holistic geology, mining, science and spirituality, the legacy of the furtrade, significance of the Little Spirit Tree, and much more. Ancient Earth and the First Ancestors not only tells a fascinating story that spans billions of years, but is also a wonderful chronicle of two people from different cultural and scientific heritages learning to understand, appreciate,and see the value and importance in each other’s way of viewing this land and the planet we all call home.

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.
