(top): Schematic view of sediment cores LEF 44, LEF 45 and LEF 50 with selected geochemical proxies Ca, Sr, Fe, and Sr/Fe ratio from XRF measurements. Different sedimentary units are distinguishable by a distinct distribution of elements. The marked washover unit is characterized by high Sr and Ca values. For the lower part of the washover sequence, a mixing of deposits from different depositional environments is documented. Relative width of core sections represents grain size composition (1—mainly silt and clay, 2—sand, 3—sand and gravel, 4—mainly gravel). For legend see also Fig. 7. (bottom): Different core sections of cores LEF 44, LEF 45 and LEF 50. Main sedimentary characteristics are depicted. On top of the lagoonal mud, a coarse-grained sequence was found, comprising up to four different subunits (I, II, III, IV). Mud drapes were found in cores LEF 44 and LEF 50. In core LEF 50, subunit I shows a clear fining-up sequence. Subunits II and III are clearly thinning landward.
