A Late Weichselian geomagnetic record from Lake Tamula, SE Estonia

A Late Weichselian palaeomagnetic record has been obtained from sediments deposited in Lake Tamula in SE Estonia, and detailed mineral magnetic studies have been undertaken to identify the carriers of remanence. The palaeomagnetic record can be compared to records from southern Sweden and Karelia in NW Russia. A westerly declination swing in the Swedish and Russian records, between 13,300 and 12,100 calender years BP is also found in the Lake Tamula sediments. Based on a floating varve chronology in the varved clay unit the deglaciation can be dated to 14,400 calender years or 12,600 radiocarbon years BP. The palaeomagnetic evidence supports the presently accepted deglaciation chronology of southeastern Estonia, which is based on radiocarbon dates of the Haanja and Otepää ice‐marginal stages.Sandgren, P., Hang, T. & Snowball, I.F., 1997: A Late Weichselian geomagnetic record from Lake Tamula, SE Estonia.
