| contents | Geochemical and palynological data from an annually laminated core sequence (Lake Belau, Schleswig-Holstein) are interpreted with respect to vegetation and settlement history on the basis of a chronostratigraphical model and archaeological evidence. Most settlement periods indicated by pollen and archaeological data can be geochemically identified in the sediment sequence using tracer elements such as K, Rb, Zr and the K/Zr ratio. Whilst air-borne pollen carry a more regional signal, the sedimentary flux of these trace elements is determined by the allogenic input from the catchment area of the lake and, therefore, provides information about the local history of settlement and agricultural land use in the lake's vicinity. This is exemplified for the period of the middle Neolithic Funnel Beaker Culture ('Iversen landnam'), where a time offset of 250 years between both signals has been detected. In contrast, both geochemical and pollen signals are highly synchronous during the Early Migration Period and the High Medieval Period. Additionally, the Fe/Ca and/or U/Fe ratio may serve as a sensitive tracer for human impact on the trophic state of the lake. The suggested impact of the Romans and the High Medieval civilization can clearly be seen (and quantified) from elevated lead input into Lake Belau sediments at this time. Effects of secular climatic changes on the sedimentary chemistry have not been detected and, if present, seem to have been obliterated by anthropogenic activity. |
