| contents | In 2008, a 404 cm long sediment core (2008-3) was recovered from 8 m depth in the southern part of Lake Big Yarovoe. It consists mostly of striated black, grey and greenish-grey silts. The poor organic content of Lake Big Yarovoe sediments posed a problem for radiocarbon dating, but the problem was solved with a geomagnetic approach. A record of geomagnetic inclinations from the studied core was compared with Holocene records of inclinations from Lake Biwa, Japan. The age model of Lake Biwa is based on two widespread tephra layers: Kawagodaira (3.15 ka BP) and Kikai-Akahoya (7.25 ka BP) (Ali et al., 1999). To produce an adequate age-depth model for Lake Big Yarovoe, we transferred the ages of the extremes that the two geomagnetic curves have in common from the Lake Biwa age model to the Lake Big Yarovoe record.
