This work is based on the observation that further major advances in geochemistry, particularly in understanding the rules that govern the ways in which elements come together to form minerals and rocks, will require the application of the theories of quantum mechanics. The book therefore outlines this theoretical background and discusses the models used to describe bonding in geochemical systems. It is the first book to describe and critically review the application of quantum mechanical theories to minerals and geochemical systems. The book consolidates valuable findings from chemistry and materials science as well as mineralogy and geochemistry, and the presentation has relevance to professionals in a wide range of disciplines. Experimental techniques are surveyed, but the emphasis is on applying theoretical tools to various groups of minerals: the oxides, silicates, carbonates, borates, and sulfides. Other topics dealt with in depth include structure, stereochemistry, bond strengths and stabilities of minerals, various physical properties, and the overall geochemical distribution of the elements.

Features 135 splendid color photographs, ranges from vast rock-landscapes recorded in Europe, America, Australia, and Iceland right down to finely detailed images of a few square millimeters. Close-ups of crystals, gems, and fossils are alternated with micro-images of the minute textures and patterns that emerge from thin, translucent sections of rocks and minerals. Literally, as well as figuratively Dirk Wiersma, the photographer, zooms in` on the subject matter, leading the reader deeper into various spaces of surprising new forms and perspectives, at times abstract, at other times (pseudo)realistic. Brief accompanying texts are written in a style that is accessible and appealing to a general audience, while also providing the necessary factual information.

Ocean Hotspots provides a comprehensive overview of recent and ongoing research on intraplate volcanism in the ocean basins with special emphasis on the Pacific Ocean. The geology of the seamounts and their associated seamount chains is described, along with detailed geophysical, geochemical and hydrothermal observations made by a multi-disciplinary group of marine geoscientists. These observations lead to a deeper understanding of how the ascending mantle melts, represented by hotspots, are able to penetrate the lithosphere, build seamounts, and enhance hydrothermal circulation. The "fixed" hotspot-generated seamount chains also provide key constraints on plate tectonic reconstructions on the Earth's crust.

Framboids may be the most astonishing and abundant natural features you've never heard of. These microscopic spherules of golden pyrite consist of thousands of even smaller microcrystals, often arranged in stunning geometric arrays. They are rarely more than twenty micrometers across, and often look like miniscule raspberries under the microscope. The formation of a framboid is the result of self-assembly of pyrite micro- and nano-crystals under the influence of surface forces. They can be found all around us in rocks of all ages and present-day sediments, soils, and natural waters. Our planet makes billions every second and has been doing so for most of recorded geologic time. As a result, there are more framboids on our planet than there are sand grains on Earth or stars in the observable universe. The microscopic size of framboids belies their importance to contemporary science. They help us better understand inorganic self-assembly and self-organization, and studying them illuminates Earth's evolutionary history. In this book, David Rickard explains what framboids are, how they are formed, and what we can learn from them. The book's thirteen chapters trace everything from their basic attributes and mineralogy to their biogeochemistry and paleoenvironmental significance. Rickard expands on the most updated research and recent developments in geology, chemistry, biology, materials science, biogeochemistry, mineralogy, and crystallography, making this a must-have guide for researchers.

Das Standardwerk fur die Geowissenschaften sowie fur alle Liebhaber von Gesteinen und an Geologie Interessierte. In diesem Buch vermittelt Roland Vinx die Grundlagen der Gesteinskunde praxisorientiert und leicht verstandlich. Dabei kommt es ihm besonders auf die Bestimmung mit makroskopischen Methoden an, d. h. unter Gelandebedingungen, ohne Mikroskop und ohne chemische Analysen. Gesteinsbestimmung erfordert eine sichere Diagnose der enthaltenen Minerale. Deswegen werden zunachst die wichtigsten gesteinsbildenden Minerale vorgestellt, danach folgen Beschreibungen der verschiedenen Gesteinsarten in einheitlich strukturierter Form und auf aktuellem Stand der Klassifikationen. Manchmal ist eine sichere Bestimmung im Gelande prinzipiell nicht moeglich. Fur solche Falle wird erlautert, wie man eine Probe fur die Analyse im Labor nehmen kann, ohne dabei das moeglicherweise sensible Vorkommen zu beeintrachtigen. Mit diesem Buch werden die Merkmale der Gesteine ohne petrographische Vorkenntnisse verstandlich. Sorgfaltig ausgewahlte, farbige Fotos der beschriebenen Minerale und Gesteine sowie von vielen gesteinstypischen Gelandeformen erleichtern das Bestimmen. Das nach nunmehr neun Jahren bereits in der 4. Auflage vorliegende Werk nimmt eine eigene Stellung neben theoretischen Lehrbuchern einerseits und Gesteins- und Mineralienfuhrern andererseits ein.

Photo Atlas of Mineral Pseudomorphism provides a comprehensive overview on the topic of pseudomorphism-in which one mineral is replaced by another but still maintains its original crystal form-a phenomenon that is far more common than currently thought and is extremely important in understanding the geologic history of rocks. There are many examples of pseudomorphs, but they have never been brought together in a single reference book that features high-resolution, full-color pseudomorph formations together with the original minerals that they have replaced. This book is the essential reference book for mineralogists, geologists or anyone who encounters mineral pseudomorphism in their work.

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.

Environmental Impact of Mining and Mineral Processing: Management, Monitoring, and Auditing Strategies covers all the aspects related to mining and the environment, including environmental assessment at the early planning stages, environmental management during mine operation, and the identification of major impacts. Technologies for the treatment of mining, mineral processing, and metallurgical wastes are also covered, along with environmental management of mining wastes, including disposal options and the treatment of mining effluents.

Crystals are sometimes called "Flowers of the Mineral Kingdom." In addition to their great beauty, crystals and other textured materials are enormously useful in electronics, optics, acoustics, and many other engineering applications. This richly illustrated text describes the underlying principles of crystal physics and chemistry, covering a wide range of topics, and illustrating numerous applications in many fields of engineering using the most important materials. It has been written at a level suitable for science and engineering students and cab be used for teaching a one- or two-semester course.
Tensors, matrices, symmetry, and structure-property relationships form the main subjects of the book. While tensors and matrices provide the mathematical framework for understanding anistropy, on which the physical and chemical properties of crystals and textured materials often depend, atomistic arguments are also needed to qualify the property coefficients in various directions. The atomistic arguments are partly based on symmetry and party on the basic physics and chemistry of materials.
After introducing the point groups appropriate for single crystals, textured materials, and ordered magnetic structures, the directional properties of many different materials are described: linear and nonlinear elasticity, piezoelectricity and electrostriction, magnetic phenomena, diffusion and other transport properties, and both primary and secondary ferroic behavior. With crystal optics (its roots in classical mineralogy) having become an important component of the information age, nonlinear optics is described along with the piezo-optics and electro-optics, and analagous linear andnonlinear acoustic wave phenomena. Enantiomorphism, optical activity, and chemical anisotropy are discussed in the final chapters of the book.

The fourth edition of Introduction to Optical Mineralogy has been thoroughly revised and updated to increase reading comprehension and improve the clarity of its illustrations. Author William D. Nesse continues his detailed discussions of the petrographic microscope, the nature and properties of light, and the behavior of light in isotropic and anisotropic minerals, with detailed coverage of uniaxial and biaxial optics. Ideal for advanced undergraduate and graduate courses in optical mineralogy, this accessible text is also an essential resource for petrology and petrography courses.

The second edition of Introduction to Mineralogy follows the highly successful first edition, which become an overnight market leader. Introduction to Mineralogy consolidates much of the material now covered in traditional mineralogy and optical mineralogy courses and focuses on describing minerals within their geologic context. It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy is available with Daniel Schulze's An Atlas of Minerals in Thin Section for a nominal additional fee.

Zeolite scientists, whether they are working in synthesis, catalysis, characterization or application development, use the Atlas of Zeolite Framework Types as a reference. It describes the main features of all of the confirmed zeolite framework structures, and gives references to the relevant primary structural literature. Since the last edition 34 more framwork types have been approved and are described in this new edition. A further new feature will be that characteristic building units will be listed for each of the framework types.
Zeolites and their analogs are used as desiccants, as water softeners, as shape-selective acid catalysts, as molecular sieves, as concentrators of radioactive isotopes, as blood clotting agents, and even as additives to animal feeds. Recently, their suitability as hosts for nanometer spacing of atomic clusters has also been demonstrated. These diverse applications are a reflection of the fascinating structures of these microporous materials. Each time a new zeolite framework structure is reported, it is examined by the Structure Commission of the International Zeolite Association (IZA-SC), and if it is found to be unique and to conform to the IZA-SC's definition of a zeolite, it is assigned a 3-letter framework type code. This code is part of the official IUPAC nomenclature for microporous materials. The Atlas of Zeolite Framework Types is essentially a compilation of data for each of these confirmed framework types. These data include a stereo drawing showing the framework connectivity, features that characterize the idealized framework structure, a list of materials with this framework type, information on the type material that was used to establish the framework type, and stereo drawings of the pore openings of the type material.
* Clear stereo drawings of each of the framework types
* Description of the features of the framework type, allowing readers to quickly see if the framework type is suitable to their needs
* References to isotypic materials, readers can quickly identify related materials and consult the appropriate reference

Zeolites are the most frequently used industrial catalysts. Their applications range from oil refining, petrochemistry and the synthesis of special chemicals to environmental catalysis. Rapid progress in basic research and the development of new processes has resulted in the first Federation of European Zeolite Associations (FEZA) School on Zeolites. Zeolites and Ordered Mesoporous Materials: Progress and Prospects reflects the programme of the first School on Zeolites, held in Prague on August 20-21, 2005. Readers gain insight into the synthesis of the ever-expanding spectrum of zeolites, zeotypes and ordered mesoporous materials including the use of zeolites and mesoporous materials as catalysts in organic conversions. These range from the fascinating ship-in-bottle systems via cascade reactions to bulk applications in oil-refining and petrochemistry. Contributions from world experts enhance the book, with select chapters on trends in the molecular sieves field, zeolite structures, ion-exchange properties of zeolites, advanced applications (with unique technologies and opportunities) and a chapter on natural zeolites.
* Contains contributions from world experts in the field
* Includes an account of the frontier topic of high-throughput techniques
* Reviews the application of quantum-chemical methods to zeolite science to show the necessity of combining experimental and theoretical approaches

Das Buch weitet den Blick uber die kurzfristige Verfugbarkeit von kritischen Metallen auf die grundlegende Frage: Kritisch fur wen? Die Autoren nehmen alle Akteure in den Blick und behandeln geologische, chemische, technische, oekonomische und soziale Aspekte wie auch Fragen des Recyclings und verbinden diese. Auch auf Fragen nach dem guten Leben und des Bergbaus aus der Sicht von Landern des Sudens, Fragen der Ressourcenpolitik und -gerechtigkeit gehen sie ein. Ein weiteres Thema sind das UN-Tiefseebergbauregime und dessen Perspektiven, wie sich zukunftig unkonventionell Erz aus der Tiefsee gewinnen lasst. Kritische Metalle werden in den ubergreifenden Zusammenhang der anstehenden Grossen Transformation eingeordnet. Das Buch beleuchtet insbesondere die grundlegende Bedeutung der stofflichen Voraussetzungen der Energiewende und die energetischen Voraussetzungen der Stoffwende wie auch der Digitalisierung. Damit lasst sich zeigen, dass nicht nur seltene Erden kritisch sind, sondern ebenso Industriemetalle wie etwa Kupfer. Ressourcenpolitik zielt unter anderem auf Sicherung der Primarversorgung mit Technologiemetallen, auf Ressourceneffizienz, Recycling und Substitution kritischer Stoffe. Trotz erster Erfolge ist die Dynamik in Richtung einer zunehmenden Dissipation wertvoller kritischer Metalle ungebrochen. Noetig ist eine rasche Umsteuerung mit dem Ziel, kritische Metalle nicht langer im grossen Stil zu verbrauchen, sondern sie klug zu gebrauchen.

Clays are increasingly becoming a major problem in the mining, extraction and value-adding processes for a wide range of commodity raw materials. Clays can impact negatively on virtually every unit process within the mining and minerals processing sector, having long-term environmental implications that go well beyond the lifetime of the mining operation. This book is the first to compile, explain and evaluate the effects of clays in the mineral processing value chain, from mining to minerals processing, and finally, tailings disposal. Focusing on topics from the chemistry and rheology of clays to their detection and dissolution behaviour, this book provides comprehensive coverage of the effects on processes such as settling, preg-robing, flotation and comminution. It is an excellent reference for professional mineralogists and geologists, industrial engineers, and researchers interested in clays and clay minerals.
