Description :
Isotope geochemistry has become the most important field of specially geochemistry and is being applied increasingly to the study of chemical processes in natural water bodies, the atmosphere and to other aspects of our environment.
This book is based on the script of lecture course In isotope geochemistry, which is given at the university of Strasbourg, France and at the Eidgenossische Tech Nisch Hochschule (ETH), Zurich, Switzerland by Peter Stille. It is intended to be read by geologists, hydrologists, geochemists and any researchers and students from the board field of environmental science. Its purpose is to isotope geochemistry applied to sedimentary and aquatic systems.
The authors have strived to construct the book in such a way that can be read and understood by those readers, especially students, who have no background in geochemistry. 7 chapters take the reader through the rock cycle from weathering on the continent to eventual deposition in the sea, looked at the largely from the perspective of radiogenic isotope geochemistry.
This book attempts to shed some light on the entire field of sedimentary isotope geochemistry, including the isotope geochemistry of natural water bodies, and objectively discusses important results of previous research in the various sub-fields. Readers are given the opportunity to critically asses this research, allowing them to apply isotopes in their own particular fields.
The first chapter consists on an introduction and basic principles of isotope geochemistry. Weathering and erosion contribute significantly to sediment formation and are discussed in chapter 2. In chapter 3, the fluvial transport to these weathering products into the sea is looked at in some detail. Chapter 4 concerns the application of various isotopic systems to the investigation of our heavily polluted environment. Chapters 5, 6 and 7 are all concerned with the marine environment. While chapter 5 concentrates on seawater and authigenic mineral isotope geochemistry, chapter 6 deals more specially with detrital and authigenic clay minerals in marine sediment for dating and for constraining mechanisms of exchange during deposition and digenesis. The final chapter concerns the behavior of the Sm-Nd isotope system in marine sediments during digenesis.
