Odsłonięta w stanowisku Stara Maryśka II sukcesja osadowa obejmuje górną część interglacjału eemskiego po zlodowacenie wisły. Na podstawie ciągłości zapisu palinologicznego w osadach wypełniających zbiornik odtworzony został przebieg zmian klimatu i środowiska w okresie późnego plejstocenu (MIS5e-MIS2). Wyniki datowań metodą OSL pozwoliły wyróżnić okresy funkcjonowania warstwy czynnej wieloletniej zmarzliny podczas zlodowacenia wisły (MIS4- -MIS2), która jest wyznacznikiem warunków peryglacjalnych panujących przed czołem lądolodu. Oznaczony został również czas formowania się wydm w rejonie stanowiska.

The sedimentary succession exposed in Stara Maryśka II site includes last part of Eemian Interglacial (MIS 5e) to Late Weichselian (MIS2) deposits. On the base of the palynological record in the paleo-lake, the climate and environmental changes during MIS 5e were reconstructed. Optically stimulated luminescence dating of the sands pseudomorphoses of ice wegdes made it possible to distinguish periods of increased aeolian activity during the Weichselian glaciation.

The paper deals with the age and palaeoenvironment interpretation of the Late Berriasian sedimentary transition from micritic calpionellid limestones to marls, corresponding to the passage from the Osnica Formation to the Kościeliska Marl Formation, Lower Sub-Tatric succession, Tatra Mts., Central Western Carpathians. Since only reliably dated sections are an appropriate basis for palaeoenvironmental study, the following pelagic and hemipelagic sections were chosen owing to enrichment in fine, clastic material and the existing biostratigraphic and magnetostratigraphic frameworks: Pośrednie III, Rówienka, Gładkie Upłaziańskie and Gęsia Szyja. The authors integrated and interpreted new, detailed data on magnetic susceptibility (MS), rock magnetism and element geochemistry from all of the sections. Well defined biostratigraphy permitted the testing of the potential of MS as a stratigraphic method. Owing to its close connection to selected terrigenous elements (e.g., Al, Th, Zr), MS could be used here as a proxy for detrital input into the basin. Its value as a correlation tool in a pelagic and hemipelagic setting was confirmed. MS permitted not only detailed correlation of the outcrops studied, but also the comparison of them with the Barlya section (Western Balkans) of the same age. This study proves that increased detrital input began in the Calpionellopsis simplex Subzone and continued into the lower part of the Calpionellopsis oblonga Subzone. It might be regarded as synchronous event within the Zliechov Basin and it is not everywhere correlated with the formation boundaries. The change in sedimentation was not only a local phenomenon. The onset of deposition of the terrigenous fraction can be identified in many sections of the Western Tethys. Two independent factors, regional regression and an increase in humidity might have contributed simultaneously to the increased detrital input in Late Berriasian time. However, this picture is further complicated by tectonic activity on local and regional scales.

The paper presents an analysis of depositional sequences of landslide peat bog situated in the depressions developed within the landslide landforms Jesionowa in the Beskid Sądecki Mts. (Outer Carpathians). The peat bog, with depositional sequence 2.80 m long, started to form at the begin-ning of the Atlantic Phase ca. 6390-5910 cal BC. Palynological and lithological analyses as well as several (14) radiocarbon age determinations of different horizons in the sediments enabled the recon-struction of palaeoenvironmental changes during the Meso-and Neoholocene. The increase in climate humidity at the beginning of the Subboreal and Subatlantic Phases was observed as delivery of minerogenic material to the peat bog basin and formation of a mineral horizon and an illuvial level within the peat. The particularly intensive delivery of allochthonous material to the peat bog took place at the beginning of the Subboreal Phase and was the result of both significant humid climate and increased human impact (colonization of the Funnel Beaker Culture) in the landslide area. Similar influence of younger colonisations of landslide area (Przeworsk Culture and, later, Valachian coloni-sation) was also recorded within the deposits of peat bog (illuvial and mineral horizons) in the early Subatlantic Phase. Rejuvenation of the landslide zone and formation of the younger landslide were connected with the increase in climate humidity at the beginning of the Subboreal Phase. The peat bog deposits situated within this younger landslide, which are ca. 1.8 m thick, are significantly con-taminated with mineral material.

The paper presents analysis of depositional sequences of two peat bogs situated in the depressions developed within the landslide landforms Pcim Sucha in the Beskid Makowski Mts. (Outer Carpathians). The older peat bog, with depositional sequence 3.75 m long, started to form at the decline of the Boreal Phase ca 7570-7330 cal BC. Palynological and lithological analyses as well as numerous (18) radiocarbon datings of different horizons in the sediment enabled reconstruction of palaeoenvironmental changes of the Middle and Late Holocene. Increase in climate humidity at the beginning of the Atlantic, Subboreal and Subatlantic Phases were observed as deliveries of minerogenic material to the peat bog basin and formation of illuvial and mineral layers within peat. The particularly intensive delivery of allochtonous material to the peat bog took place at the beginning of the Subatlantic Phase and was the result of both significant humid climate and increased human impact (colonization of the Przeworsk Culture) in the landslide area. Rejuvenation of the landslide zone and formation of the second landslide were connected with this period and processes. Deposits of peat bog situated within this younger landslide, which are ca 1.3 m thick, are significantly contaminated with mineral material.

Interdisciplinary palaeoenvironmental studies, conducted near the multi-cultural archaeological sites in the Horodyska River valley (Lublin Upland, East Poland), enable to reconstruct natural and anthropogenic changes of fluvial landscape in the Holocene. The changes are evidenced by the results of archaeological, geological, sedimentological and palynological investigations, as well as radiocarbon and thermoluminescence dating. The Horodyska fluvial system started functioning at the turn of the Late Vistulian and Preboreal. From the beginning of the Subatlantic the record of environmental changes in valley deposits bears the mark of human impact. Main phases of settlement on the river valley bottom (higher terrace) correspond to rather dry periods (Neolithic, Bronze Age, Halstadt period, period of Roman influence, early Middle Ages). Moistening of climate and its associated rise of groundwater level forced people to move settlement on the loess plateau and found a stronghold at the turn of the 11th and 12th centuries.
