“…Taking into account the welldated initial layer of lacustrine sedimentation in the Lake Perespilno Bałaga 2004) with the similar pollen composition, we can suppose that this zone represents even older deposits from the end of the Pleniglacial. Such a conclusion is also confirmed by the results of radiocarbon dating of bottom layers of lacustrine deposits (older than 12,300 BP) obtained for other lakes of the Łęczna-Włodawa Lake District (see Bałaga, 2007). Two distinguished subzones (DB-1) indicate the differentiated succession of communities.…”

Abstract:In this paper, the history of Durne Bagno, i.e. the largest peat bog in the Lublin Polesie, is shown. Peat bogs are a unique element of the Polesie landscape. They occur mostly in the subregion of the Łęczna-Włodawa Lake District occupying 1.07% of its area. They fill basin-shaped depressions without outflow, often in the immediate vicinity of dystrophic lakes. Based on interdisciplinary research, the changes of vegetation cover and the Durne Bagno lake-mire ecosystem in the Late Glacial and Holocene are presented. The environmental conditions are reconstructed from pollen analysis, detailed identification of algae of Pediastrum genus and chemical composition of deposits, together with the results of Cladocera analysis. The distribution of archaeological artefacts in the surroundings of Durne Bagno peat bog gives the view on the intensity of settlement in this area. The duration of the limnic and mire stages during the development of the ecosystem was different in different parts of the examined depression. In its central part the limnic stage lasted about 8000 years and included the period from the Late Glacial to the middle Holocene (to about 6000 BP). It is represented by 7 pollen zones and 6 chemical zones. The mire stage contained a part the Atlantic period and on the Subboreal and Subatlantic periods. It is represented by 4 pollen zones and 5 chemical zones. Limnic and mire deposits differ widely in the concentrations of chemical elements. The contents of mineral material and almost all analyzed elements in limnic deposits are high. These deposits are characterized by positive correlation between the contents of Zn and Cr and the frequency of Cladocera fauna. Peat contains very low amount of mineral material. The contents of Ca, Sr and Ba are rather high in sedgemoss peat. The concentrations of these elements decrease upwards due to oligotrophic processes and sedentation of sedge-Eriophorum-Sphagnum peat. Peat succession was modified by pastoral economy of prehistoric man.

“…An increase of CaCO 3 content in the early Younger Dryas section of the sediments from the lake was an effect of the drop in the groundwater level which stimulated the oxidation of soils in the lake catchment (Goslar et al 1999). During the late Older Dryas/early Alleröd period the phase when sediments were enriched with CaCO 3 was more clearly recorded, inter alia, in Karaśne Lake sediments in eastern Poland (Bałaga 2007).…”

“…One of the best studied sediment profiles of this type of lake is from Gością _ z Lake (Ralska- Jasiewiczowa et al 1998Jasiewiczowa et al , 2003Goslar et al 1999). Sediments that are also valuable from the point of view of Late Pleistocene/Early Holocene paleogeography include those of karst lakes situated north of Lublin in Poland (Bałaga 2007(Bałaga , 2010 and in western Belarus, as well as ox-bow lake sediments, e.g. in the Sandomierz Basin (Nalepka 1994;Kołaczek 2010), and those of single lakes left behind by mountain glaciers (Obidowicz 1996).…”

The Late Vistulian and Holocene evolution of Jezioro Lake: a record of environmental change in southern Poland found in deposits and landforms

et al. 2012

Jezioro Lake is the only natural lake in southern Poland outside mountainous areas to have existed continuously since the Pleistocene. The record of environmental change in the Late Vistulian (Weichselian) and Holocene is preserved in the deposits and landforms around the lake. This paper presents the results of paleogeographical and paleoecological research that emabled us to reconstruct the history of the Jezioro Lake. At the end of the Vistulian period, the outlet of the lake was blocked by a parabolic dune moving in from the west. Limnic sedimentation was evident in the sediment core at all levels from the Holocene, with remains of Cladocera, Chironomidae larvae, and aquatic plants. The lake did not disappear at that time, although its area decreased by a factor of 12 by the end of the period. Paleobotanical research permitted the reconstruction of sequences of plant communities and changes in nutrient status and water level. An initial oligotrophic lake, as indicated by the presence of Isoe¨tes lacustris L., changed to a eutrophic lake, as indicated by the presence of Potamogeton natans L. and Nuphar sp., then the lake progressed to the present-day dystrophic lake that is surrounded by a swamp. The profile of organic deposits contains a record of environmental change at least since the Younger Dryas in southern Poland.

Abstract:In this paper we report the results of interdisciplinary investigations of deposits filling small closed depressions in the Western Polesie region. There were reconstructed the environmental changes and the main evolution phases of four morphometrically similar forms (=research sites) situated in the Lublin and Volhynia parts of the Polesie region. The gathered sedimentological, chronostratigraphical, palynological and geochemical data evidence great lithological (peats, gyttja, calcareous tufa) and age (Late Glacial, Neoholocene) differences between the deposits filling individual forms and indirectly suggest their karstic origin.
