Down-core variations of the high-resolution magnetic susceptibility (0.1 cm steps)have been obtained for kasten and pilot cores from sites CON01-603 and CON01-605. This allowed the transfer of AMS 14C dating performed on kasten cores to the performed on kasten cores to the pilot cores subjected to paleomagnetic investigations. Note the discrepancies in the magnetic susceptibility curves from the pilot core from site CON 01-605 (Vydrino Shoulder) measured in 2001 and 2003, respectively (right). Several large peaks visible in the first measurement from 2001 (dashed lines) disappeared after a 2-year-long storage. This is a first hint for the presence the ferromagnetic, chemically unstable greigite.
