Palynostratigraphy of the Poozerie Glaciation (Vistulian) in Belarus

Abstract

A palynological examination was applied to sediments of the last glaciation (Poozerie. Vistulian) in Belarus. Accompanied by geologic setting of deposits. as well as radiocarbon and thermoluminescence dating, the Poozerie sequence could be ascribed to three substages. i.e. Kulakovo, Dvina and Naroch. The Kulakovo substage (early Poozerie) corresponds to the oxygen isotope stage 5d-a, and comprises the West Dvina megastage with the short Black Shore interstage and the megainterstage (two stages of Mirogotshi and Sloboda, and three interstages of Chericov, Suraz and Polotsk). The Dvina substage (Pleniglacial), corresponding to the oxygen isotope stages 4 and 3, consists of the Mezin and Orsha megastages and the separating megainterstage with three middle Poozerie interstages (Turov, Shapurovo and Borisov) and two stages (Rogachevo and Michalinovo). The Naroch substage (oxygen isotope stage 2) represents the Late Glacial. There are several interstages during the Poozerie Glaciation: Chericov (Amersfoort), Suraz (Brorup), Polotsk (Odderade), Turov (Moershoofd), Shapurovo (Hengelo) and Borisov (Denekamp).
