The interval of high abundance of ostracods in the sediment sequences of PE-1 and PE-2 starts in sandy silt deposits (OAZ B, Figs 4 and 5), although generally the high sand fraction content related to a higher sedimentation rate seems to dilute the actual microfaunal content.
Correlation of most OAZs in the sequences studied is quite easy because of the remarkable similarity of ostracod distribution, particularly in PE-1 and PE-5.
2001), local pollen assemblage zones PAZ Pe-1 and PAZ Pe-2, identified at the transition from glaciolacustrine clay to lake marl, could be correlated with the Younger Dryas Chronozone (YDr) (Hang et al.
stevensoni at the beginning of lime accumulation in PE-1 and PE-5 (OAZ C1), refers to the possible water depth shallower than 4 m (Niinemets 1999).
If the suggestion about the lake level and possible sedimentation hiatus in foreshore areas holds true, the carbonate accumulation started first in the central part of the lake represented by PE-1 and PE-5 sequences already at the end of the YDr (Fig.
reptans present in OAZ D in PE-1 and PE-5, which could be explained with the water having been deep enough (> 4 m) in these points and with the fact that the aforementioned regression did not affect the ostracod assemblage in the deeper central parts of the lake.
OAZ 0 containing rich ostracod fauna between empty samples of varved clay, which is explained by redeposition of sediments; (b) PE-1 and PE-2 .
