Figure F23. MST-derived whole-core magnetic susceptibility (top) compared with the natural remanent magnetization (NRM) intensity measured after 25-mT AF demagnetization for the lowermost 40 m of the Site 1233 splice. Two intervals of weak magnetic susceptibility and NRM intensity imply diagenetic loss of fine-grained ferromagnetic phases relative to coarse-grained material.
