HIGH-RESOLUTION PALAEOSECULAR VARIATION IN NORTHERN EUROPE DURING THELAST 3200 YEARS

Variations in the declination, inclination and relative palaeointensit y of Earth's magnetic field during the last 3200 yr have been recorded from a sequence of annually laminated sediments in Lake Pohjajarvi (l at 62 degrees N), Central Finland. The magnetic mineralogy is uniform, with only small variations in concentration of magnetite of pseudo-si ngle-domain (PSD) grain size. The variations in direction were found t o be very similar to records reconstructed from other lakes in Finland and northwest Russia, while the relative palaeointensity curve can be correlated accurately with archaeomagnetic data from Central Europe.
