Fig. 6 (a–c) Concentration of selected major and minor elements in deeper sections of the 8 m core versus their average concentration values in the upper 10.5 cm sediment; minor depletion or enrichment is recorded for Fe and Mn and trace elements that form oxy-anions that can be scavenged by Fe-oxidhydroxides; depletion shows systematic increase from light to heavy REEs. Trace elements marked by * and REEs were measured by ICPMS (Analyst: M. Zimmer, GFZ-Potsdam)
