Clay coatings from a modern soil chronosequence: A tool for estimating the relative age of well-drained paleosols

Three geomorphic surfaces characterize the landscape of southeastern Mississippi: uplands, stream-cut terraces, and modern alluvium. The present floodplain, has poorly developed soils, and lacks illuvial accumulations. Soils developing in the uplands have abundant and prominent illuvial clay coatings up to 2 mm thick, while the terraces have minor clay coatings less than 1 mm thick.
