(top): Schematic view of sediment cores LEF 1, LEF 18 (AAS) and LEF 47 (XRF) with selected geochemical proxies. Findings for core LEF 46 are analogous to core LEF 47, for trench LEF S1 analogous to the upper part of core LEF 18. Different sedimentary units are characterized by a distinct distribution of elements. 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 Figs. 3 and 7. (bottom): Different core sections of cores LEF 1, LEF 47 and LEF 18. Main sedimentary characteristics are depicted. On top of the lagoonal mud and a former surface, a coarse-grained sequence was found which is thinning landward. In core LEF 18, only one subunit (I or II) was found.
