Paper described geomorphological characteristics of landform sets which occur on research areas investigated by Polish geomorphologists on Spitsbergen. These area involve four areas along the western coast of Spitsbergen, i.e. vicinities of the Kaffiøyra, the Werenskioldbreen, the Calypsostranda, and the Hornsund, as wel as one area located in the central part of Spitsbergen, i.e. vicinity of Billefjord with special emphasis on surroundings of the Petuniabkukta. Landforms are characterized in different morphogenetic terms, mainly glacial, peryglacial, deundational, slope, fluvial, even eolian factors and processes.

Luminescence dating was applied in the studies on the evolution of the St. Laurent Mountain in Kałdus (Lower Vistula Valley, Poland), where archaeological excavation revealed a settlement sequence. The core of the hill is constituted by eolian sands which formed the dune. Above them there is a sequence of deposits consisting of three levels of the silty sand anthropogenic deposits separated by top eolian cover and a layer of the burnt material. Three samples from the eolian base and one from the eolian cover were taken for luminescence analysis. The absolute age was established by a comparison of TL and OSL results. The basement of the St. Laurent Mountain (till and ablation sands) was created by a receding glacier during or short after the last glacial period. It suggests the age limit for the dune not older than 18,000 years. Luminescence dating indicates, that the dune formation was initiated in Pleniglacial just after deglaciation, ca. 16,500 years ago and the top eolian cover was established in Neolithic Age, between 6000 and 8000 years ago. Numerous archaeological findings from the upper part of the mountain and C-14 dates of the burnt material provided data for reconstruction of the last phase of this formation.

Stratigraphy of the Vistulian glacial events in the southern part of the Lower Vistula region in the north Poland is presented. Lithostratigraphic units and TL dating of Vistulian deposits exposing along the Vistula valley between Toruń and the Chełmno Lakeland are described in detail. The obtained results indicate that the Vistulian sequences in the Lower Vistula region were deposited during five palaeogeographical episodes. Three glacial events were distinguished: the first at the beginning of the Middle Vistulian (~65O70 ka) and two younger ones during the Late Vistulian. The Middle and Late Vistulian glacial events were separated by a long ice-free period, between 65 and 30 ka.

The aim of this paper is to present in detail a method, adopted in our laboratory, for the determination of annual dose. In particular, an analysis is focused on the thermoluminescence dating of eolian sediments from Kępa Kujawska. The advantage of the presented method is that partial matrix doses for alfa, beta and gamma radiation are determined simultaneously from the high resolution gamma spectrometry measurements.

A dune in Kępa Kujawska is located on the edge of the Toruń Basin. Preliminary studies on the natural thermoluminescence (TL) revealed relative chronology of the dune. The TL profile exposed three stages of the dune formation, which are correlated with three eolian members of dune deposits indicated by sedimentological investigations. The experiments on optical bleaching show that light (sunlight as well as laboratory light) only partially resets natural TL in that material. The high level of residual TL was taken into account in absolute dating of the dune. The TL ages obtained for quartz sand from the upper member are confirmed by radiocarbon dating of soil and burn horizon in proximal part of hte dune. Archaeological remains found in the dune give another evidence for truthfulness of TL dating results. The TL age of the middle member is consistent with conclusions from pollen analysis in the dune and its environments. The formation of this dune was started in the Late Glacial, probably in the Younger Dryas. In this period eolian deposition was stimulated by variable climate conditions. The upper member of the dune is connected with Neolithic and Iron Cultures when anthropogenic activity initiated eolian processes again. During the Atlantic and the Subatlantic periods the dune was rebuilt.
