Abstract Dashed lines mark some correlation levels of the cores from Lake Baikal with the dated δ18O record from ODP 677 (Shackleton et al., 1990), see also Fig. 3. Diagenetic features such as dissolution of magnetite and mineralization of greigite are marked according to Fig. 4. Laschamp and Iceland Basin excursions are indicated as La. and Ic., respectively. Inclination and declination records could provide information on paleosecular variations (periodicity ≤105 years and directional variability <20°, according to Butler, 1992). In the present study, we did not interpret inclination and declination records in terms of paleosecular variations since slight sediment disturbances could produce slight deviations of ChRM declinations and inclinations.
