Vegetation and stratigraphy of the Mazovian (Holsteinian) Ineterglacial sections from Dobropol and other new sites in western Polesie Region, south-eastern Poland

Geo log i cal map ping in east ern Po land re sulted in new find of or ganic de pos its near W³odawa. Pol len and plant macrofossils anal y ses at the Dobropol site proved de po si tion dur ing the Mazovian (Holsteinian) Inter gla cial (MIS 11). Pol len spec tra in di cated strong pre dom i nance of Carpinus in the op ti mum phase (pol len pe riod III), sug gest ing in ten - sive in flu ence of con ti nen tal cli mate in this part of Po land. The paleolake Dobropol was shal low, with many spe cies of rushes in a lit to ral zone. Dur ing the Liviecian (MIS 10) and the Krznanian (MIS 8) Glaciations the res er voir was oc cupied by an ice-dam lake, in which silt and clay de po si tion pre vailed. The Mazovian Inter gla cial or ganic de pos its were also re corded in im me di ate sur round ings of the study area. Based on geo log i cal and paleobotanical ex am i na tion of the Dobropol site, the ice sheet of the Krznanian Gla ci ation seemed to have reached at least the south ern part of Włodawa. The ice sheet has not cov ered pre sum ably the whole study area as its ad vance oc curred in sev eral lobes. The sur roundings of W³odawa in the West Polesie Re gion are the third larg est Mazovian paleo-lakeland area in Po land, apart from the vi cin i ties of Biała Podlaska and the £uków Plain.
