Download or read book Origin of Potassium rich Silica deficient Igneous Rocks written by Alok Krishna Gupta and published by Springer. This book was released on 2014-11-11 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes the occurrence, geochemistry, mineralogy, petrology and phase-equilibria studies in air and under high pressures related to the most intriguing group of potassium-rich mafic and ultramafic rocks, often including host of exotic mineral assemblages including feldspathoids. Mantle-derived K-rich melts had intrigued most of the founders of Geology and many of the later experts in the field of Igneous Petrology, because they are sometimes associated with carbonatites and even diamond. They tend to contain anomalous concentration of many such elements as K, Rb, Sr, U, F, P, etc., along with Ni, Co and Cr indicating a mixture of crust and mantle materials. Although these rocks occur rarely in ancient geologic time, they have been erupting mostly in modern geological history (less than last 120 Ma or so). Are the old age data real or the result of a sampling problem? Modern observations leave no doubt that sediments must be subducted on a large scale. There is now evidence that the upper mantle (and perhaps even the lower mantle) is not homogeneous but rather like a fruit cake, and that there are thermal anomalies in the mantle resulting from deep mantle plumes or subduction. Is this related to release of these unusual rocks clearing the mantle of left over subduction materials? This volume, written for those interested in the geochemistry of K-rich melts from the deep Earth, reviews the present state of knowledge of these unique igneous rocks. The author is an expert in the field of Igneous Petrology and the book will serve as a valuable reference book for researchers and academicians in the discipline.
Download or read book Potassic Igneous Rocks and Associated Gold Copper Mineralization written by Daniel Müller and published by Springer. This book was released on 2015-08-31 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the geochemical and petrological characteristics of potassic igneous rock complexes, and investigates the different tectonic settings in which these rocks occur. The authors provide an overview and classification of these rocks and elucidate the geochemical differences between barren and mineralized potassic igneous complexes. High-K rocks host a number of epithermal gold and porphyry copper-gold deposits. In recent years, there has also been growing recognition of an association of such rocks with iron-oxide copper-gold (IOCG) deposits, intrusion-related gold deposits (IRGDs) and possibly even Carlin-type gold deposits. This book is not only relevant to academic petrologists working on alkaline rocks, but also to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terrains. This fourth, updated and expanded edition incorporates new data and references from Africa, Australia, Brazil, China, Greece, Iran, Mongolia, North America, Russia and Turkey, including new maps and sections and new color plates of high-grade gold-copper ore from major deposits hosted by potassic igneous rocks.
Download or read book Cenozoic Volcanism in the Tyrrhenian Sea Region written by Angelo Peccerillo and published by Springer. This book was released on 2016-12-01 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an updated edition of the book by the same author: "Plio-Quaternary volcanism in Italy - Petrology, geochemistry, geodynamics," published in 2005 by Springer. This edition has the same structure as the previous publication, with a general introduction; various chapters dedicated to different volcanic provinces in Italy; and a final chapter on the relationships between magmatism and geodynamics. It includes information that has become available in the last ten years, and new chapters have been added offering detailed discussions of the Oligo-Miocene orogenic volcanism on Sardinia and of some small outcrops of fragmented volcanic rocks occurring in several places of the Apennines. This new edition now covers the entire Tyrrhenian Sea magmatism of the last 40 Ma. Lastly, it includes two appendices: Appendix 1 reports on a comparison between the Tyrrhenian Sea volcanism and the partially coeval magmatism along the Alps and adjoining areas and has the objective of highlighting similarities and difference that can tell us much on geodynamics and magmatism between the converging plates of Europe and Africa. Appendix 2 is an update of the 2005 edition appendix and deals with classification of orogenic rocks with special emphasis on potassic alkaline volcanics.

Download or read book Lamprophyres Lamproites and Related Rocks written by L. Krmíček and published by Geological Society of London. This book was released on 2022-02-09 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleoproterozoic to Cenozoic lamprophyres, lamproites and related rock types (e.g., orangeites, kimberlites) are volatile-rich mafic magmatic rocks with a unique potential for the investigation of processes affecting mantle reservoirs. They originated from primary mantle-derived melts that intruded both cratons and off-craton regions, which were parts of former supercontinents – Columbia, Rodinia and Gondwana–Pangea. Well-known for hosting economic minerals and elements such as diamonds, base metals, gold and platinum-group elements, they are also significant for our understanding of deep-mantle processes, such as mantle metasomatism and mantle plume–lithosphere interactions, as well as large-scale geodynamic processes, such as subduction-related tectonics, and supercontinent amalgamation and break-up. This book aims to provide a timely overview of the state-of-the-art and recent advances as achieved by various research groups around the world. Mineralogical, geochemical, geochronological and isotope analyses are used to decipher the complex petrogenesis and metallogenesis of these extraordinary rocks, and unravel a complete history of tectonic events related to individual supercontinent cycles.

Download or read book Magmas Rocks and Planetary Development written by Eric A. K. Middlemost and published by Routledge. This book was released on 2014-06-03 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variety of volcanic activity in the Solar System is widely recognised, yet the majestic sequences of magmatic processes that operate within an active planet are much less well known. Providing an exposition of igneous rocks, magmas and volcanic erupsions, this book brings together magnetic and volcanic data from different tectonic settings, and planets, with explanations of how they fit together. It systematically examines composition, origin and evolution of common igneous rocks, yet also examines a variety of rare magnetic rocks that play a crucial role in the global magma/igneous rock system.
