The second edition of this classic book provides an updated look at crystal field theory - one of the simplest models of chemical bonding - and its applications. Crystal field theory provides a link between the visible region spectra and thermodynamic properties of numerous rock-forming minerals and gems that contain the elements iron, titanium, vanadium, chromium, manganese, cobalt, nickel or copper. These elements are major constituents of terrestrial planets and significantly influence their geochemical and geophysical properties. A unique perspective of the second edition is that it highlights the properties of minerals that make them compounds of interest to solid-state chemists and physicists as well as to all earth and planetary scientists. This book will be useful as a textbook for advanced students as well as a valuable reference work for all research workers interested in this subject.

Many materials used in industry are crystals. These crystals often show anomalies, such as sudden softening or embrittlement at certain temperatures. If controlled, such behavior can be extremely useful, for manufacturing and high-technology applications. This is one of the first books to describe the recently determined physical origins of such behavior, and provides an insight into the important thermodynamic principles and microstructural properties involved. It starts with the fundamental principles of structural phase transitions in materials. Ferroelasticity, twinning and related microstructures are then described. Landau-type theories of phase transitions are introduced, together with details of elastic and specific heat anomalies, the formation of spontaneous strain, and the generation of solitary waves at temperatures close to the transition point.

The subject of mineralogy has moved away from the systematic treatment of mineral groups toward the study of the behavior of minerals in response to geological processes. It is vital that we understand the physics and chemistry of minerals as this response generally involves structural and chemical changes within individual minerals as well as reactions between minerals. This is the first text to provide an introduction to modern mineralogy for undergraduate students. The main, and often complex, concepts required to understand minerals and the processes that take place within them are presented in an easy to follow manner without any complex mathematical treatment. The book deals with solid-state transformations in minerals, which take place in response to changes in temperature and pressure, as well as introducing the basic crystallography, physics and chemistry needed to understand these processes. No knowledge of physics, chemistry and mathematics beyond high-school level is assumed.

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.

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.

Step-by-step Q&As with detailed colour photographs for easy identification. The Firefly Guide to Minerals, Rocks & Gems is designed for easy and reliable identification of minerals, gems and rocks. Beginning with the stone's colour and any streak, and using a sequence of straightforward questions and answers - aided by 1,300 photographs and drawings - it's easy to narrow down the possibilities among 350 minerals, gems and rocks to the conclusive classification. The book organizes the rocks by colour: Blue, Red, Yellow, Brown, Green, Black, and White. Identification begins with noting the colour of the rock's streak (i.e., vein, line). Identification is then further narrowed down with respect to Colour, Crystal form, Hardness, Lustre, Density, Cleavage, Break and Tenacity. Each rock's main photograph shows the general or typical view, and identification tips about features are noted in the margins of the respective page. Similar stones are presented for comparison and tips are provided that can eliminate imposters. Drawings show the mineral's crystal shape. The chemical formula reveals the elements from which the mineral is composed. There is also information about where the stone is typically found and some of the ways that humans have utilized it. Packed with beautiful photographs of earth's many rocks, minerals and gems, The Firefly Guide to Minerals, Rocks & Gems is perfect for amateur mineralogists and collectors.

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.

Komatiites erupted billions of years ago as pulsating streams of white-hot lava. Their unusual chemical compositions and exceptionally high formation temperatures produced highly fluid lava that crystallized as spectacular layered flows. Investigation of the extreme conditions in which komatiites formed provides important evidence about the thermal and chemical evolution of the planet, and the nature of the Precambrian mantle. This monograph, written by three experts with long experience in the field, presents a complete account of the characteristics of komatiites including their volcanic structures, textures, mineralogy and chemical compositions. Models for their formation and eruption are evaluated (including the anhydrous vs. hydrous magmas controversy). A chapter is also devoted to the valuable nickel and copper ore deposits found in komatiites. Komatiite is a key reference for researchers and advanced students interested in petrology, Archaean geology, economic geology, and broader questions about the evolution of the Earth's crust and mantle.

A volcanic eruption occurs when a magma-filled fracture propagates from its source to the surface. Analysing and understanding the conditions that allow this to happen constitute a major part of the scientific field of volcanotectonics. This new volume introduces this cutting-edge and interdisciplinary topic in volcanological research, which incorporates principles and methods from structural geology, tectonics, volcano-deformation studies, physical volcanology, seismology, and physics. It explains and illustrates the physical processes that operate inside volcanoes and which control the frequencies, locations, durations, and sizes of volcanic eruptions. Featuring a clear theoretical framework and helpful summary descriptions of various volcanic structures and products, as well as many worked examples and exercises, this book is an ideal resource for students, researchers and practitioners seeking an understanding of the processes that give rise to volcanic deformation, earthquakes, and eruptions.
