The Encyclopedia of Mineralogy provides comprehensive, basic treatment of the science of mineralogy. More than 140 articles by internationally known scholars and research workers describe specific areas of mineralogical interest, and a glossary of 3000 entries defines all valid mineral species and many related mineral names. In addition to traditional topics - descriptions of major structural groups, methods of mineral analysis, and the paragenesis of mineral species - this volume embraces such subjects as asbestiform minerals, minerals found in caves and in living beings, and gems and gemology. It includes current data on the latest in our geological inventories - lunar minerals. It describes the properties, characteristics, and uses of industrial resources such as abrasive materials and Portland cement. A directory will guide traveling mineralogists to the major mineralogical museums of the world, with their special interests noted. Clear technical illustrations supplement the text throughout. To help the student and professional find particular information there are a comprehensive subject index, extensive cross-references of related topics (whether in this volume or others in the series), and reference lists to background information and detailed advanced treatment of all topics. The Encyclopedia of Mineralogy is a valuable reference and source for professionals in all geological sciences, for science teachers at all levels, for collectors and `rock hounds', and for all who are curious about the minerals on earth or those brought back from outer space.

The phenomenonofspontaneous ordering in semiconductoralloys, which can be categorized as a self-organized process, is observed to occur sponta neously during epitaxial growth of certain ternary alloy semiconductors and results in a modification of their structural, electronic, and optical properties. There has been a great dealofinterest in learning how to control this phenome non so that it may be used for tailoring desirable electronic and optical properties. There has been even greater interest in exploiting the phenomenon for its unique ability in providing an experimental environment of controlled alloy statistical fluctuations. As such, itimpacts areasofsemiconductorscience and technology related to the materials science ofepitaxial growth, statistical mechanics, and electronic structure of alloys and electronic and photonic devices. During the past two decades, significant progress has been made toward understanding the mechanisms that drive this phenomenon and the changes in physical properties that result from it. A variety of experimental techniques have been used to probe the phenomenon and several attempts made atproviding theoretical models both for the ordering mechanisms as well as electronic structure changes. The various chapters of this book provide a detailed account of these efforts during the past decade. The first chapter provides an elaborate account of the phenomenon, with an excellent perspective of the structural and elec tronic modifications itinduces.

With an approach that stresses the fundamental solid state behaviour of minerals, this 1995 text surveys the physics and chemistry of earth materials.

This book contains 18 invited contributions to the first Inter national Symposium on Order-Disorder Transformations in Alloys+. They cover the major aspects of this group of phase transformations. Although structural order-disorder transformations have been investigated for over 50 years the invited papers, the research papers - whose titles and authors are listed in the appendix - and the discussions at the Symposium have demonstrated very active continued interest and con siderable recent progress in the subject. This is true for theoretical work as weIl as for experimental studies and for the development of materials whose properties result from order-disorder transformations. + Some major national conferences on ordering were held in the USA and in the USSR in recent years; the proceedings are available in the following pUblications: Local Atomic Arrangements Studied by X-Ray Diffraction, Gordon & Breach, New York 1966 2 Ordered Alloys, Claitor's Publ.

Statistical Thermodynamics of Semiconductor Alloys is the consideration of thermodynamic properties and characteristics of crystalline semiconductor alloys by the methods of statistical thermodynamics. The topics presented in this book make it possible to solve such problems as calculation of a miscibility gap, a spinodal decomposition range, a short-range order, deformations of crystal structure, and description of the order-disorder transitions. Semiconductor alloys, including doped elemental semiconductors are the basic materials of solid-state electronics. Their structural stability and other characteristics are key to determining the reliability and lifetime of devices, making the investigation of stability conditions an important part of semiconductor physics, materials science, and engineering. This book is a guide to predicting and studying the thermodynamic properties and characteristics of the basic materials of solid-state electronics. - Includes a complete and detailed consideration of the cluster variation method (CVM) - Provides descriptions of spinodal decomposition ranges of crystalline alloys - Presents a representation of thermodynamics characteristics and properties as a miscibility gap by using the different approximations of CVM - Covers a unique, detailed consideration of the valence force field model with the complete collection of formulas

This monograph, suitable for use as an advanced text, presents the statistical mechanics of solids from the perspective of the material properties of the solid state. The statistical mechanics are developed as a tool for understanding properties and each chapter includes useful exercises to illustrate the topics covered. Topics discussed include the theory of the harmonic crystal, the theory of free electrons in metal and semiconductors, electron transport, alloy ordering, surfaces and polymers.

Coastal Conservation and Management provides the reader with a synthesis of the range and variation of the main coastal formations and includes practical guidance on their management. The book discusses all the main coastal habitats of importance for nature conservation (saltmarsh, shingle, sand dune and seacliff) as well as combinations of these habitats (estuaries and other coastal wetlands). It offers a comprehensive picture of both the soft sedimentary formations and those which are more resilient. While these habitats have all been covered elsewhere in the literature, no single volume gives such a wide-ranging account. An attempt is made throughout to provide the reader with a basic understanding of the importance and range of variation of each habitat and coastal ecosystem. The principal issues are discussed and the key management options identified. Some prescriptive suggestions are made, though for the most part, the reader is left to ponder the issues and their possible solutions. The book argues for a more dynamic approach to the conservation of coastal habitats commensurate with the nature of the ecosystems themselves. Coastal Conservation and Management also stresses interrelationships with human use. By bringing these elements together, it highlights the need for new approaches to conservation management, which accept that change can be a healing force in the rehabilitation of degraded coastal areas. In this context, the book brings the geomorphology of coastal systems to the fore, suggesting that they may be more robust than is normally suggested. In the face of global warming, Coastal Conservation and Management also advocates a reappraisal of the value of natural systems as a means of providing a more flexible and efficient response to rising sea levels.

Radiation Processes In Crystal Solid Solutions is a monograph explaining processes occurring in two classes of crystal solids (metal alloys and doped alkali halides) under irradiation by various types of radiation (alpha, beta, gamma, X-radiations, ions). While metal alloys may differ in high radiation stability, solid solutions based on alkali halides are very radiation-sensitive materials. Radiation defect production mechanisms, intrinsic and extrinsic radiation defects, a role of complexes an impurity-radiation defect which explain distinction in radiating stability of the specified classes of solid solutions are discussed in this e-book. To describe radiation induced phase transformations, two approaches are highlighted: kinetic and thermodynamic. This e-book also includes research on the effect of small radiation doses in a structurally solid phase state of a solution along with a semi-quantitative estimation of radiation effects with respect to temperature changes. This e-book should be a useful reference for advanced readers interested in the physics of radiation and solid state physics.
