Middle Paleolithic Geomorphological and Paleoenvironmental Setting of the Alsace Region: State of the Art and New Data

The Upper Rhine Plain is part of a Cenozoic graben, which is approximately 40 km wide and 300 km long. This geological structure determines the geometry and the thicknesses of the Quaternary sediments, with a subsiding central zone and loess-covered alluvial terraces on its margins.
