Rates of Chemical Weathering of Rocks and Minerals

Steven M. Colman

David P. Dethier

Researchers in geomorphology, geochemistry, quaternary geology, soil science, and mineralogy will welcome this volume, the first to focus exclusively on rates of silicate chemical weathering. Consisting largely of previously unpublished data from six countries, the volume examines the latest experimental, modelling, and field results.
New information is presented on topics of current research interest, including inferences about chemical mechanisms at the level of mineral surfaces, and data relating weathering rates to landscape evolution over millions of years. The volume integrates the variety of approaches used by diverse subdisciplines in the assessment of weathering rates, and provides up-to-date references.
