Stable Isotope Geochemistry is an introduction to the use of stable isotopes in the geosciences. It is subdivided into three parts:- theoretical and experimental principles;- fractionation mechanisms of light and heavy elements;- the natural variations of geologically important reservoirs.The 5th edition has been revised and extended and now includes a new chapter on palaeoclimatology. Special emphasis has been given to the growing field of "e;heavy"e; elements. Many new references have been added, which will enable quick access to recent literature. 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.
