Soils and Sediments Mineralogy and Geochemistry [Paperback]

Clays and soils are of great importance in various scientific fields, such as agriculture and environmental science, and in mineral deposits. Students and close collaborators of Georges Millot, the eminent French clay sedimentologist, have put together a book with topics ranging from weathering processes and diagenetic evalution of sediments to sedimentary mineral deposits. The book is of interest to practitioners, advanced students as well as teachers in the above fields.Clays and soils are of great importance in various scientific fields, such as agriculture and environmental science, and in mineral deposits.
