Fluvial deposits represent the preserved record of one of the major nonmarine environ ments. They accumulate in large and small intermontane valleys, in the broad valleys of trunk rivers, in the wedges of alluvial fans flanking areas of uplift, in the outwash plains fronting melting glaciers, and in coastal plains. The nature of alluvial assemblages - their lithofacies composition, vertical stratigraphic record, and architecture - reflect an inter play of many processes, from the wandering of individual channels across a floodplain, to the long-term effects of uplift and subsidence. Fluvial deposits are a sensitive indicator of tectonic processes, and also carry subtle signatures of the climate at the time of deposition. They are the hosts for many petroleum and mineral deposits. This book is about all these subjects. The first part of the book, following a historical introduction, constructs the strati graphic framework of fluvial deposits, step by step, starting with lithofacies, combining these into architectural elements and other facies associations, and then showing how these, in turn, combine to represent distinctive fluvial styles. Next, the discussion turns to problems of correlation and the building of large-scale stratigraphic frameworks. These basin-scale constructions form the basis for a discussion of causes and processes, including autogenic processes of channel shifting and cyclicity, and the larger questions of allogenic (tectonic, eustatic, and climatic) sedimentary controls and the development of our ideas about nonmarine sequence stratigraphy."

The role of hydrothermal fluids during the crystallization of layered intrusions and the ore deposits they contain has long been debated. This book summarizes the evidence for fluid-crystal-liquid (hydromagmatic) interactions and their importance for the understanding of the formation of platinum-group deposits in layered intrusions. It discusses the composition of igneous fluids in mafic magmatic systems, the generation and movement of these fluids in layered intrusions, their impact in altering the mineralogy and composition of the originally precipitated assemblages, and their role in the transport of the platinum-group elements (PGE). Using examples from the Bushveld complex of South Africa and other intrusions, this book provides a comprehensive overview of the hydromagmatic model for the origin of various features of layered intrusions. It is a useful reference for academic researchers and professional geologists working on economic mineral exploration, layered igneous intrusions, and hydrothermal metallogenesis.

In this edition, most of the commonly occurring minerals of igneous, metamorphic and sedimentary rocks are discussed in terms of structure, chemistry, optical and other physical properties, distinguishing features and paragenesis. Important correlations between these aspects of mineralogy are emphasized wherever possible. The content of each section has been updated where needed in the light of published research over the 21 years between editions. Tables of over 200 chemical analyses and formulae are included and a number of older entries have been replaced by more recent examples. Major new features: Entirely new views of crystal structures in perspective using CrystalMaker colour images; Over 60 colour photographs of minerals in thin sections of rocks under the petrological microscope; Considerably expanded treatment of feldspar and zeolite minerals; Mineral identification table based on birefringence and listing other properties; Colour strip with appropriate interference colours and birefringences for the main rock-forming minerals. This book will be useful to undergraduate students of mineralogy, petrology and geochemistry, especially those at third or fourth year, engaged in more advanced courses or specialized projects, and also as a reference work for students for 'Masters' degrees by taught courses or research. For doctorate students, and research workers in the Earth Sciences as well as those in Materials Science and other related disciplines, this work can be useful as a condensed version of the very extensive treatment presented in the volumes of the DHZ Series 'Rock-Forming Minerals', second edition. Buyers through online retailers should contact the Mineralogical Society in order to receive the free CD which goes with the book ([email protected]).

The review chapters collected here were the basis for a two-day short course on nontraditional stable isotopes held in May 2004 in Montreal, Canada.

All Earth Science students need to understand the origins, environments, and basic processes that produce igneous and metamorphic rocks. This concise introductory textbook provides students with the essential knowledge needed to understand how petrology relates to other topics in the geologic sciences, and has been written specifically for one-semester courses. Throughout, the emphasis is on interpreting the mineralogy and petrology of rock suites in terms of origin and environment, with the first half of the book concentrating on igneous rocks, and the second half on metamorphic rocks. This Second Edition has been thoroughly revised and brought completely up-to-date. It now includes a new chapter on the application of stable and radiogenic isotopes in petrology, introducing students to the concept of isotopic fractionation and describing the process of radioactive decay. The discussions of phase diagrams, connections between igneous and metamorphic rock suites, and convergent margin magmatism have also been expanded. There is a new glossary of terms, updated end-of-chapter exercises, and updated further readings.

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.

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.

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.

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 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.
