Correlation (by Levkovskaya, 1987, 2001) of some lake transgressions and regressions of Eastern Latvia (Lubana Holocene Lake) and Kaliningrad area of Russia (Zedmar Holocene Lake) with climatic reconstructions (by Klimanov) and with Lubana pollen diagrams of sediments without archaeological layers: I-peat bog Zosu (by Ilves, Medne, 1979) and: II-upper part of archaeologically sterile sediments at the site Zvidze (by Loze et al., 1984).
