Opis:: Lacustrine organic sediments were sampled at Gronowo (Chełmno Plateau) and Piotrkowo (Dobrzyń Plateau) located within a widespread system of subglacial channels separated by the large Drwęca ice-marginal valley. They have been examined for their pollen, plant macro-remains and geochemistry, as well as radiocarbon-dated. The analyses have allowed reconstructing the evolution of the area and presenting an asynchronous appearance of two lakes. Before lake sedimentation, glaciolimnic sediments from the end of Plenivistulian, at the site of Piotrkowo, was dated. Lacustrine sedimentation started during the Allerød at Gronowo, and during the Preboreal at Piotrkowo. The different age of the two lakes is ascribed mainly to differences in the Late Glacial drainage conditions which directly affected the melting away of dead-ice blocks buried in the channels.

Opis:: In or der to re con struct en vi ron men tal changes in the Borzechowo mire, a sed i ment core was sub jected to macrofossil and strati graphic anal y ses. The mire is lo cated in the east ern part of the Pom er a nian Lakeland (Tuchola For est, northern Po land). It is a limnogenic mire, formed as a re sult of terrestrialisation of a wa ter body. The time of basal peat accu mu la tion was es ti mated by ra dio car bon dat ing as 9860±130 14C BP (Gd-12393) and by palynological anal y sis as Preboreal. The anal y sis of macrofossils shows that in that pe riod, con sid er able hy dro log i cal changes took place in the study area. These hy dro log i cal changes were caused by melt ing of dead ice blocks that was com mon place in the Late Gla cial and the Early Ho lo cene.
