Abstract

Natural lakes are rare in the Czech Republic, since most of territory of southern Moravia has never been glaciated. As indicated by new palynological research, this does not fully apply to southern Moravia. The ongoing palynological research at some sites shows at the number of lakes existed there in the past. Well known examples are the former Vracov Lake, Vacenovice-Jezero Lake as well as Čejčské jezero Lake and Kobylí Lake. The analysed organic sediments were sampled in a shallow depression at the locality of Čejčské jezero Lake (thickness 1-2 m, Čej 27) near the village Čejkovice NW of Hodonín, southern Moravia. The locality has been found during geological survey. By virtue of favourable circumstances, it has been scheduled for protection and proclaimed the Čejčské jezero Lake Natural Monument. Palynological and paleoalgological study of the above mentioned sediments was made. It occurred that a lake really existed at this locality at the time of its origin in the Late Glacial period. During its development, deposition of sediment occurred mainly in the Holocene. One sample of the locality was radiocarbon-dated (Hv: 14C und 3H-Laboratorium, Niedersächsisches Landesamt für Bodenforschung, Hannover, BRD) at its base (depth 2 m) at 9990 +- 275 years BP.
