Opis:
Artykuł prezentuje aktualny stan rozpoznania stanowisk eemskich w centralnej Polsce oraz uwagi natury pale - ogeograficznej wynikające z analizy ich rozprzestrzenienia, w nawiązaniu do genezy mis jeziornych, charakteru wypełnień i paleoreliefu. Zestawiono 58 stanowisk posiadających paleobotanicznie udokumentowane osady z interglacjału eemskiego oraz wyszczególniono kolejnych 30 miejsc występowania kopalnych osadów organogenicznych uznanych za eemskie. Wskazano, wykorzystując także materiały dotychczas niepublikowane, na znaczne zagęszczenie kopalnych zbiorników, porównywalne z obecnym rozprzestrzenieniem jezior na pojezierzach północnej Polski. Określono, na podstawie danych palinostratygraficznych, że zanik jezior polodowcowych mógł trwać nawet około 80 tys. lat.
The article presents the current state of recognizing of the Eemian subfossil flora sites in central Poland and palaeogeographic remarks resulting from the analysis of their distribution in relation to the origin of palaeolakes, the nature of their infillings and palaeolandscape. 58 sites in the area with palaeobotanic documentation of the Eemian interglacial have been summarized and also following 30 places of fossil organogenic deposits considered as Eemian were listed. Indicated have been, also using the materials previously unpublished, a significant frequency of the fossil lake depressions comparable with the present spread of lakes in the northern Poland lakelands (lake districts). It has been determined, referring to palynostratigraphy, that the decline of glacial lakes may take up to ca 80 thousand years.

Opis:
Well-developed N-S trending esker, described in literature as the Gostynin esker, consists of parallel ridges associated witch a tunnel valey flanked by the Vistulian (Weichselian) till plain. The sedimentary succession of one of the ridges is known in the Osada site. Complexity of the esker internal structure is expressed by 4 sedimentary units of different environments. The lowest, coarsegravelly (O1), developed by infilling a subglacial tunnel. The following one, making the main part of the esker ridge, is a sandy unit (O2) deposited in an ice-walled open channel. Locally, the deposits show normal synsedimentary faults. The O3 unit of fine-grained sediments was laid in a stagnant water. The succession is topped by a thin discontinous layer of flow till (O4). Sedimentation took place when the ice-sheet changed its dynamics from active to stagnant.

The pol len data re veal that sed imen ta tion at Wietrzychowice has be gun at the be gin ning of the Ho lo cene (Preboreal). Pol len anal y sis was used to determine stratigraphy with regard to sediment characteristics. The pollen spectrum was divided into 8 LPAZes (1-7Xa, 7Xb) which were also, where pos si ble, stratigraphically clas si fied. Ra dio car bon dat ing of 6 730 ± 90 BP (5 730–5 480 BC, MKL-702) at depth of 1.20 m con firmed the pol len anal y sis age es ti ma tion. Five set tle ment ep i sodes were found in or ganic sed i ments in the up per part of the W5 core. The first was pre sum ably dur ing the Preboreal, the sec ond in the early At lan tic, the third in the late At lan tic (prob a bly Neo lithic FBC), the fourth in the early Mid dle Ages and the last one in the late Mid dle Ages. The pol len anal y sis was use ful to point ir reg u lar i ties in sed i ment suc ces sion. Such a sit u a - tion made palaeoenvironmental in ter pre ta tion dif fi cult, but fur ther re search is still needed to en able an ac cu rate re construc tion.

Opis:
The article is focused on the most recent investigations of glaciotectonic structures in high escarpment exposures of the Vistula valley from Dobrzyń to Kuzki in the western part of the Płock Basin. Deformations involve Neogene and occasionally the Lower Pleistocene deposits and they are not expressed as landforms. Structural investigations and analysis of archival geological data provided new information on the origin of large-scale shear structures. Results obtained are clearly contrary to the concept of Brykczyński (1982) regarding valley-side glaciotectonics in the Płock Basin. An emergence of the extensive zone of serial thrust structures of significant amplitude (up to 100–150 m) was found to have not been controlled by a palaeovalley. A driving mechanism is interpreted as a gravity spreading in front of ice sheets advancing from north-northeast during the South Polish Complex (Dorst-Elsterian).

Opis:
Vistulian climatic changes are recorded in various sedimentary environments of central Poland, both in the extraglacial zone of the last glaciation and also in the area occupied by the last Scandinavian Ice Sheet, being reflected by palaeobotanical, palaeozoological, sedimentological and geochronological data. The most pronounced morphogenetic processes are linked to a glacial succession in the northern part of the study area, referred to the Upper Plenivistulian. For most of the study area, located in the extraglacial zone, the climatic changes are reconstructed from lake-bog, fluvial, slope and aeolian sedimentary successions. In central Poland, no site has been documented so far where there would be a continuous biogenic record through the whole Vistulian. Environmental changes recorded through the Vistulian include temperature, vegetation and the dynamics of morphogenetic processes, and sedimentary environments most useful for assessing changes occurring at that time may be indicated. The Early Vistulian is best recognized within biogenic deposits, as in the older part of Plenivistulian. The conditions in the earlier part of the Plenivistulian are best reported from fluvial and slope deposits with evidence of permafrost and of glacial conditions, though only in the northern part of the study area. Changing conditions of the Late Vistulian are expressed via well-documented morphogenetic processes occurring in all (except glacial) sedimentary environments, lake-bog and aeolian environments providing the most complete information about the nature of this period. Most of the Vistulian deposits reflect cold periods. There is a distinctive increase in periglacial impacts throughout the Plenivistulian with the apogee during the Upper Plenivistulian and interstadial warmings did not influence this trend. Each sedimentary environment provides significant data about the climate evolution, and processes playing a leading role vary according to the Vistulian stratigraphic unit. The consolidation of findings from regional research has provided new directions for further interdisciplinary studies.
