Geoarchaeology is the application of geoscience to the study of archaeological deposits and the archaeological record. Employing techniques from pedology, geomorphology, sedimentology, geochronology, and stratigraphy, geoarchaeologists investigate and interpret sediments, soils and landforms at the focal points of archaeological research. Edited by Rolfe D. Mandel and with contributions by John Albanese, Joe Allen Artz, E. Arthur Bettis III, C. Reid Ferring, Vance T. Holliday, David W.
