Abstract This study is based upon palaeobotanical reinvestigation of the Pleistocene deposit strata revealed by test drillings in the buried valley at the Zidini site, southeastern Latvia. Up to 100 m thick lake sediment strata covered by three different till layers have been found in three 120–171 m deep test drillings. New palynological and plant macroremain analysis for sediment samples from core No. 43 have been done. These results and data from the earlier investigations at Zidini were compared. Clearer insights into depositional environment and vegetation change during the accumulation of sediments in the palaeolake have been acquired. According to recent studies and correlation of obtained palaeobotanical data, the palaeolake sediments were accumulated from the Elsterian 1 Late Glacial, through the Cromerian Complex, including two interglacials (Cromer III and Cromer IV) separated by cooling of Glacial C and hiatuses. The upper part of the palaeolake sediment sequence accumulated during Elsterian 2 Early Glacial stadial and interstadial conditions.
