A Handbook of Silicate Rock Analysis


Book Description

without an appreciation of what happens in between. The techniques available for the chemical analysis of silicate rocks have undergone a revolution over the last 30 years. However, to use an analytical technique most effectively, No longer is the analytical balance the only instrument used it is essential to understand its analytical characteristics, in for quantitative measurement, as it was in the days of classi particular the excitation mechanism and the response of the cal gravimetric procedures. A wide variety of instrumental signal detection system. In this book, these characteristics techniques is now commonly used for silicate rock analysis, have been described within a framework of practical ana lytical aplications, especially for the routine multi-element including some that incorporate excitation sources and detec tion systems that have been developed only in the last few analysis of silicate rocks. All analytical techniques available years. These instrumental developments now permit a wide for routine silicate rock analysis are discussed, including range of trace elements to be determined on a routine basis. some more specialized procedures. Sufficient detail is In parallel with these exciting advances, users have tended included to provide practitioners of geochemistry with a firm to become more remote from the data production process. base from which to assess current performance, and in some This is, in part, an inevitable result of the widespread intro cases, future developments.













Pharmacology of Fluorides


Book Description

This volume is the completion of work initially planned several years ago as a compilation of selected aspects of the biological effects of fluorides. The first portion appeared in Volume XXII (1966) of this Handbuch, under the title "Pharmacology of Fluorides, Part 1. " Inasmuch as the present volume is an integral part of the original project, justification for offering it to the scientific community remains the same as that originally set forth. This may be recapitulated as follows. The tremendous increase in the annual production of fluorides over the amounts produced thirty years ago, together with the increased diversity of their uses has correspondingly increased the hazard associated with these materials. That is to say, the possibilities of encountering their characteristic toxic effects under the conditions of their use has increased because the variety, amounts and ways of usage have increased. Their inherent toxicity, of course has not changed, but the increased hazard has led to a vast increase in the amount and scope of research reported. It is the purpose of these volumes to review selected aspects of this literature. Rochester, N. Y. , February 1970 FRANK A. SMITH Acknowledgements Even the casual reader of this volume will soon realize that contributing authors, as well as those contributing to its predecessor, Volume XX/I, have made good use of tables of data, figures and pertinent quotations from previously published work.
