As the use of beryllium grows worldwide, the need for a single source of information on this important but toxic element is of increasing importance. This comprehensive book describes all aspects of the current sampling and analysis techniques for trace-level beryllium in the workplace. It offers both a historical perspective and a description of the state-of-the-art in a single place. It covers the challenges inherent in sampling procedures such as reproducibility, limited sample volume, surface sampling materials and collection efficiency. It also deals with the problems involved in analytical techniques including lower detection limits, identification and compensation for matrix interferences, greater sensitivity requirements and the need for more robust preparation techniques. Future trends, including development of real-time beryllium sampling and analysis equipment, are also explored. Readers will gain an understanding of sampling and analytical techniques best suited for sensitive and accurate analysis of beryllium at ultra-trace levels in environmental and workplace samples. Many “standard” sampling and analysis techniques have weaknesses that this book will help users avoid.

The overall format of previous editions has been maintained and new information has been incorporated in a similar style. This edition has two new chapters, on the manufacture and enhancement of gemstones and the old chapter on the detection of synthetic, imitation and composite stones has been rearranged. In the past decade the development of new synthetics has proceeded apace. Nowadays clean rubies and emeralds need very careful investigation since they could be natural or synthetic. However careful use of the microscope can still elucidate many problems and new instruments are shown in the text.

This standard book on minerals, first published in 1882, has been completely revised and updated for the first time in 20 years. Silicate minerals are now described in a separate chapter, using crystal-chemical sub-divisions. Non-silicates are treated under the Dana system of classification. The existing classification, based on principal economic elements, has been retained and modernized to assist both the geochemical analyst and the economic geologist needing to know the various minerals associated with a particular element. Each element's world production totals and uses are included. Other revisions to the text have also been made. For over a century this book has served as an important compendium of key information about minerals and as a widely adopted teaching text. Colin Gribble was joint author of "A Practical Introduction to Optical Mineralogy" (with Allan Hall) and "Geology for Civil Engineers" (with Adam McLean). He is also active as a consultant geologist and a researcher in the engineering/geochemical field.

The book aims to explain the variations of near-Earth plasma observed over seismically active areas several days/hours before strong seismic shocks. It demonstrates how seismo-ionospheric coupling is part of the global electric circuit and shows that the anomalous electric field appearing in active seismic areas is the main carrier of information from the earth into the ionosphere. The discussion of physical mechanisms is based on experimental data. The results can be regarded as the basis for future applications such as short-term earthquake prediction. It proceeds to describe existing complex systems of space-born and ground-based monitoring for electromagnetic and ionospheric precursors of earthquakes, as well as those still under construction. It is an excellent text for courses and contains a wealth of information for those scientists working in the field of natural disaster reduction.

The second volume of this two volume work begins with a summary chapter on optical techniques which is intended as a quick reference, and a summary for those who have not purchased the first volume. A short second chapter discusses the use of the various charts, tables, graphs and mineral descriptions contained in the book, and the mineral descriptions given are detailed and up to date, and are intended for use with either grain mounts or thin sections, an innovative feature. Each mineral description is accompanied by a block diagram showing the relationship between optical and crystallographic directions, and almost every mineral is shown in a coloured or black and white photograph, or in some cases, both. The mineral groups are arranged alphabetically with names in upper page corners, and the optical features associated with cleavage surfaces are given for each mineral.

This book reviews current ideas explaining the formation of granite in terms of melting, segregation, ascent and emplacement. It introduces an alternative hypothesis that granites are endogenic in that they essentially form and remain at melting sites in the middle–upper crust under conditions of abnormally high heat flow. The book highlights results of Chinese research over the last 30 years in English for the first time.
