Download or read book Petrology of Polygenic Mafic-Ultramafic Massifs of the East Sakhalin Ophiolite Association written by Felix P. Lesnov and published by CRC Press. This book was released on 2017-01-12 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph is concerned with results of studies of petrology of mafic-ultramafic massifs as part of the East Sakhalin ophiolite association. It generalizes and interprets a large body of data (mainly original data) on geology, petrography, petrochemistry, and geochemistry of rocks; mineralogy and geochemistry of rock-forming and accessory minerals; chromite and platinum contents, and isotopic age of zircons from rocks of the typical mafic-ultramafic massifs of the East Sakhalin ophiolite association: Berezovka, Shel’ting, Komsomol’sk, and South Schmidt. Gabbroids from the Berezovka massif contain ultramafic xenoliths. Ultramafic rocks are locally cut by gabbroid and pyroxenite veins. Three spatially close but genetically autonomous bodies are distinguished in the structure of the massifs under study: protrusion of upper-mantle restitic ultramafic rocks (harzburgites, lherzolites, and dunites); intrusion of orthomagmatic gabbroids (gabbronorites, gabbro, and norites) that cuts it; and contact-reaction zone, located along the boundaries between gabbroid intrusion and ultramafic protrusion, which consists of hybrid ultramafic rocks (wehrlites, websterites, clinopyroxenites, and their olivine- and plagioclase-containing varieties) and hybrid gabbroids (melano- and mesocratic olivine gabbronorites and gabbro as well as troctolites). The hybrid ultramafic rocks and gabbroids are the product of interaction between mafic melts and restitic ultramafic rocks. Taking into account the later formation of the gabbroid intrusions compared to the ultramafic protrusions, the massifs in question are determined as polygenic. The idea of their polygenic formation is supported by data on the isotopic age of zircons from the Berezovka massif rocks. In this monograph the author develops his earlier proposed concept of polygenic formation of mafic–ultramafic massifs belonging to ophiolite associations. The book addresses a wide circle of petrologists and practicing geologists as well as senior-year students and postgraduates studying problems of mafic-ultramafic magmatism.

Download or read book Magmatic Sulfide Deposits written by Anthony J. Naldrett and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written by a leading authority on the subject of magmatic sulfide deposits. An overview of deposit types, accompanied by a summary of the resources of nickel, copper and platinum-group elements in the world’s principal known deposits, is followed by a summary of the relevant physical chemistry. The core of the book comprises a discussion about the geology and geochemistry of each of the deposit types in turn, accompanied by the implications of this data to the origin of the deposits in the light of our understanding of the chemical processes involved. A final chapter focuses on the use of the genetic concepts in exploration.

Download or read book Tectonic Growth of a Collisional Continental Margin written by Kenneth D. Ridgway and published by Geological Society of America. This book was released on 2007 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The convergent margin of southern Alaska is considered one of the type areas for understanding the growth of continental margins through collisional tectonic processes. Collisional processes that formed this margin were responsible for multiple episodes of sedimentary basin development, subduction complex growth, magmatism, and deformation. Two main collisional episodes shaped this Mesozoic-Cenozoic continental margin. The first event was the Mesozoic collision of the allochthonous Wrangellia composite terrane. This event represents the largest addition of juvenile crust to western North America in the past 100 m.y. The second event is the ongoing collision of the Yakutat terrane along the southeastern margin of Alaska. This Cenozoic event has produced the highest coast mountain range on Earth (Saint Elias Mountains), the Wrangell continental arc, and sedimentary basins throughout southern Alaska. Active collisional processes continue to shape the southern margin of Alaska, mainly through crustal shortening and strike-slip deformation, large-magnitude earthquakes, and rapid uplift and exhumation of mountain belts and high sedimentation rates in adjacent sedimentary basins. This volume contains 24 articles that integrate new geophysical and geologic data, including many field-based studies, to better link the sedimentary, structural, geochemical, and magmatic processes that are important for understanding the development of collisional continental margins."--Publisher's website.

Download or read book Large Igneous Provinces written by Richard E. Ernst and published by Cambridge University Press. This book was released on 2014-09-25 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large igneous provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100,000 km3, and often above 1 million km3. They are linked to continental break-up, global environmental catastrophes, regional uplift and a variety of ore deposit types. In this up-to-date, fascinating book, leading expert Richard E. Ernst explores all aspects of LIPs, beginning by introducing their definition and essential characteristics. Topics covered include continental and oceanic LIPs; their origins, structures, and geochemistry; geological and environmental effects; association with silicic, carbonatite and kimberlite magmatism; and analogues of LIPs in the Archean, and on other planets. The book concludes with an assessment of LIPs' influence on natural resources such as mineral deposits, petroleum and aquifers. This is a one-stop resource for researchers and graduate students in a wide range of disciplines, including tectonics, igneous petrology, geochemistry, geophysics, Earth history, and planetary geology, and for mining industry professionals.

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.
