Opis:
Alluvial and oxbow deposits preserved 18 m above the Skawa River valley floor are related to the Early Vistulian. Pollen analysis of the two mainly terrestrial profiles revealed a boreal forest succession. The age of the deposits is discussed.

Opis:
Two sections of sediment from small oxbow-lake infillings located in different river valleys in central Poland were studied by cladoceran analysis in order to examine the response of aquatic ecosystems to the Younger Dryas. Lithological and geochemical records, as well as chydorid (Chydoridae) ephippia analysis were also used to reconstruct Younger Dryas climate trends. A high concentration of cladocerans, as well as the presence of Cladocera taxa preferring warmer water, was found. It is likely that local processes in the oxbow lakes were important, because the presence of warm-preferring taxa was also related to their habitats and their development. Yet local environmental forces, such as the influence of the rivers, habitat modification, macrophyte abundance, and eutrophication, were not only major factors to affect the Cladocera diversity in the Younger Dryas. The observation of changes in the composition and concentration of Cladocera in oxbow-lake infillings indicates that most of the changes occurred in response to climate changes.

Opis:
The article presents results of research of three sections (Kuców 9, 10 and 16). Two of them record fluvial and lacustrine interglacial sediments and the third, cold-stage glaciolacustrine sediments. They were formed inside the Miocene – Pliocene syncline depressions in a central part of the southern horst within the Kleszczów Graben. Fluvial and lacustrine deposits of the Middle Pleistocene Interglacial (Mazovian or Ferdynandovian in the Czyżów Formation) are described from the Kuców 9 and 10 sections. Their sediments are located in marginal parts of a buried river valley and within an oxbow palaeolake, then covered by glaciofluvial deposits of the Ławki (Early Saalian) and Rogowiec (Late Saalian) Formations. The Kuców 16 section comprises ice-dam sandy lithofacies (Kuców Formation, Elsterian) of a marginal part in a proglacial lake. Two pollen diagrams of K65/15 and Kuców 9 sections represent the Mazovian (Holsteinian) succession, although in the Kuców 9 section some features are typical for the Ferdinandovian succession.
