Abstract

Down-core variations of normalised relative paleointensity after removal of intervals affected by diagenesis (magnetite dissolution and/or greigite formation) and correlation to the relative paleointensity record from ODP Site 984 (Channell, 1999). In addition to AMS 14C dating and the geomagnetic excursions, the age model was completed and refined by tuning the relative paleointensity records to the equivalent record from ODP Site 984 (Channell, 1999; Fig. 8). The relative paleointensity variations in Lake Baikal and ODP Site 984 are well correlated. This confirms the global geomagnetic field origin of the relative paleointensity variations documented in the present study. In addition, it shows that local sedimentary variations have no effect on the paleomagnetic records.
