Soil micromorphology deals with the microscopic study of undisturbed soil and regolith samples, making use especially of thin sections and petrographic techniques. It exists as a discipline for almost 70 years. Micromorphology is used by pedologists, quaternary geologists, sedimentologists, and since two decennia intensively by archaeologists. This book provides the state of art in the field of genetic interpretation of micromorphological features, which is not restricted to the classic genetic soil horizons, but also covers processes of soil material formation and weathering, and the results of human activities and regoliths in a wider sense.
