Stepwise post-glacial transgression in the Rhône Delta area as revealed by high-resolution core data

► Stepwise post-glacial transgression is documented from modern Rhône Delta plain. ► We present a multiproxy analysis of two continuous cores, 40 to 50 m long. ► A complete record of swamp, estuarine and nearshore deposits forms the TST. ► Short-term (ca. millennial-scale) cycles are laterally tracked within the TST. ► High-resolution sequence stratigraphy is depicted for the first time onshore Rhône.
