Download or read book Lamprophyres written by N. M. S. Rock and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following their recognition by GUmbel (1874), lamprophyres were treated for an entire century as little more than obscure curiosities. Although this situation has changed recently, with a flowering of publications and active workers, lamprophyres remain almost the only group of igneous rocks which have not yet received attention in a dedicated monograph. In five exploratory reviews (1977-1987), the writer aimed to set out what was known about these rocks. The lUGS Subcommission on igneous rock systematics had meanwhile presented its nomenclatural framework (Streckeisen 1979). All this has now been overtaken by a recent explosion of interest, epitomized not least by lamprophyres' greater prominence in the 4th International Kimberlite Conference Proceedings. More data have become available since 1985 than over the entire previous century, and it is obviously impossible for such an extraordinary outpouring to be fully reviewed in this first, preliminary book. At the risk of dissatisfying some readers, therefore, this book concentrates on factual matters, and on a broad overview rather than minutiae. Because not even a world map of known lamprophyres was previously available, almost half the book is deliberately taken up by the first global lamprophyre compilation, and its commensurately extensive Bibliography. Such a compendium of largely objective information is believed to be of more immediate interest and lasting value than a premature pottage of petrogenetic polemic. Chapters 1-7 bring previous studies up to date, and concentrate on factual information.

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.

Book Synopsis Igneous Petrogenesis A Global Tectonic Approach by : B.M. Wilson
Download or read book Igneous Petrogenesis A Global Tectonic Approach written by B.M. Wilson and published by Springer Science & Business Media. This book was released on 2007-09-23 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a major text in igneous petrology, this innovative book offers a much-needed, radically different approach to the study of igneous rocks. Bridging a long-recognized gap in the literature by providing petrogenic models for magmatismin terms of global tectonic processes, it encompasses geophysics and geochemistry in a comprehensive treatment of the subject. Most textbooks in igneous petrology have intended to avoid discussion of potentially controversial petrogenetic models. However, this is precisely the sort of information senior students of igneous petrology require. Dr Wilson has drawn on 15 years of research and 10 years of teaching experience in writing an account of what is now a well established understanding of the processes involved in environments of magma generation. She provides full discussions of the major-element, trace-element, and radiogenic isotope characteristics of magmas generated in different tectonic settings and she deals with the information derived from such data concerning magma source regions and their ascent trough the Earth's lithosphere. Additionally each chapter contains a summary of geophysical data relating to crustal and mantle structure and the location of magma reservoirs. The modular format of the book will facilitate its use by all students, researchers and professionals with an interest in igneous petrology. A basic knowledge of geochemistry, mineralogy, phase diagrams, regional geology and global tectonics is assumed, but such advanced topics as trace element and isotope geochemistry can be omitted initially if the reader's background is inappropriate. The text is profusely illustrated and the bibliography contains over 1000 carefully selected references. Marge Wilson graduated in geology at the University of Oxford. She then spent a year at the University of California, Berkeley, and subsequently studied the petrogenesis of nepheline syenites from the Gardar province of Greenland, leading to a PhD from the University of Leeds. Her research has focused on island-arc, oceanic-island and intra-continental plate tectonic settings.

Book Synopsis The Metallogeny of Lode Gold Deposits by : Ulrich Kretschmar
Download or read book The Metallogeny of Lode Gold Deposits written by Ulrich Kretschmar and published by Elsevier. This book was released on 2015-11-24 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Metallogeny of Lode Gold Deposits: A Syngenetic Perspective is a synthesis of lode gold vein forming processes, addressing the commonality in similar worldwide deposits. The book’s empirical model incorporates widely known and accepted principles of ore deposition and shows how it applies in the volcanic-sedimentary greenstone belt environment. Several chapters detail outcrop maps and photos of field occurrences and textures. The interpretations flow directly from the authors’ field work, and are coupled with analyses of underlying physical processes. Utilizing detailed geological mapping, field work, and chemical analyses as the basis of a syngenetic formation mode, the text arms readers with the tools necessary to accurately analyze and interpret new data on the subject. This includes information on decoding the significance of asymmetry in vein formation, as well as the role of lamprophyres in gold camps, how Archean geology requires integration into a lode vein formation model, and how to develop an understanding of the worldwide applicability of gold cycles to lode vein formation and exploration and how it can be applied to deposits of all ages. Presents the first book to galvanize lode gold research into a single authoritative reference Simplifies the complexity of lode gold’s underlying processes and presents valid concepts surrounding the lode gold forming environment Features color figures, illustrations, and photos that enrich the content’s focus and aid in the retention of key concepts

Book Synopsis Potassic Igneous Rocks and Associated Gold-Copper Mineralization by : Daniel Müller
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 2013-04-17 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been increasing interest from geoscientists in potassic ig neous rocks. Academic geoscientists have been interested in their petrogenesis and their potential value in defining the tectonic setting of the terranes into which they were intruded, and exploration geoscientists have become increasingly interested in the association of these rocks with major epithermal gold and porphyry gold-copper deposits. Despite this current interest, there is no comprehensive textbook that deals with these aspects of potassic igneous rocks. This book redresses this situation by elucidating the characteristic features of potassic (high-K) igneous rocks, erecting a hierarchical scheme that allows interpre tation of their tectonic setting using whole-rock geochemistry, and investigating their associations with a variety of gold and copper-gold deposits, worldwide. About two thirds of the book is based on a PhD thesis by Dr Daniel Muller which was produced at the Key Centre for Strategic Mineral Deposits within the Department of Geology and Geophysics at The University of Western Australia under the supervision of Professor David Groves, the late Dr Nick Rock, Professor Eugen Stumpf!, Dr Wayne Taylor, and Dr Brendon Griffin. The remainder of the book has been compiled from the literature using the collective experience of the two authors. The book is dedi cated to the memory of Dr Rock who initiated the research project but died before its completion.
