Description :
This paper provides a detailed interpretation of downcore variations in the mineral magnetic signatures of lake and floodplain sediment cores by considering new data which examine the variability in soil characteristics, an analysis of the particle size controls on the mineral magnetic signature, and the presentation of new geochemical data for the lake sediments. The sediment of the Old Mill reservoir provides the only suitable record for the application of a simple mixing model which is developed in order to quantify changes in the relative contribution of topsoil and subsoil through time.
