Stable Isotope Geochemistry is an introduction to the use of stable isotopes in the geosciences. For students and scientists alike the book will be a primary source of information with regard to how and where stable isotopes can be used to solve geological problems. It is subdivided into three parts: i) theoretical and experimental principles, ii) fractionation processes of light and heavy elements, iii) the natural variations of geologically important reservoirs. In the last decade, major advances in multicollector-ICP-mass-spectrometry enable the precise determination of a wide range of transition and heavy elements. Progress in analysing the rare isotopes of certain elements allows the distinction between mass-dependent and mass-independent fractionations. These major advances in analytical techniques make an extended new edition necessary. Special emphasis has been given to the growing field of "e;non-traditional"e; isotope systems. Many new references have been added, which will enable quick access to recent literature.

The first edition of this book was published in 1973, the second, totally rewritten, followed 7 years later in 1980. Because the field of stable isotopes is still grow- ing and exerting an increasing influence on geosciences in general, it seems to be necessary, after a further 7 years, to revise the edition again accordingly. Not only has the previous edition been updated, but two completely new chapters on the isotopic composi- tion of mantle-derived material and on the isotopic composition of the ocean during the geologie past, have been added. The references concentrate on re cent literature. In some cases, older references have been omitted to save space. I do not intend to underrate the value of older publications, but only to keep the reference list - al- ready very voluminous in relation to the totallengt- from becoming even larger. An early draft has been reviewed by Russell Harmon and Alan Matthews. John Valley has se nt me a preprint of an artic1e on metamorphie rocks. To all three of them I owe my deepest thanks.

Since the publication of the previous edition advances in multicollector-ICP-mass-spectrometry allow precise measurements of new isotope systems. In this new edition therefore, 42 elements with resolvable natural variations in isotope composition are discussed.
