This study uses a range of magnetic parameters, eg. Susceptibility (X), Saturation Isothermal Remanence (SIRM), Anhysteretic Remanence (ARM), interparametric ratios (ARM/X, SIRM/X, SIRM/ARM) and coercivity of remanence data (IRM-n/SIRM, (BO)CR), coupled with various dating methods (eg. moss increment counting and radiometric dating) to estimate the magnetic deposition onto some Scandinavian peat bogs. The sites available included 4 from southern Finland, 5 from northern Finland, 2 from northern Norway and 1 from southern Denmark. In addition to the magnetic techniques, a range of chemical determinations (iron, copper, zinc, lead, nickel and, where available, manganese) have been made, or are utilised, for all the peat cores. The reproducibility of the primary magnetic deposition record at Kaurastensuo, southern Finland has been examined. The rise in magnetic particulate concentrations, termed the magnetic 'take-off', was consistently dated to about 1931 for 7 of the 8 cores used, regardless of hummock-hollow ...
