“…Among the northern rocks, there is a distinct predominance of Paleozoic limestones (about 40%), allowing the comparison of the till layer with the level correlated with the younger Sanian two glaciation among the South Polish glaciations in the Silesian Lowlands. In the studied fraction (10-35 mm), the percentage of Mesozoic sandstones does not differ from other in the same sandstone in the Saalian deposits of the Polish Lowlands (Górska-Zabielska 2008, Górska-Zabielska & Wachecka-Kotkowska 2014, Czubla 2015, Górska-Zabielska et al 2021.…”

The article presents the results of research from the Mokrzeszów site in the Sudetic Foreland. Lithopetrographic and sedimentological analyses of sediments from the Middle Polish Glaciations (Early Saalian, Odranian, MIS6) in this area indicate the overrepresentation (90–95%) of large Scandinavian erratics. The deposits, representing a repetitive sequence of Gp-Gms-Sp-Sh/Sr(Dmm) lithofacies, accumulated during at least two episodes of glacial outburst floods and six sedimentary cycles. High-energy flows are estimated for the Gms and Gp facies at about 5 m∙s−1 and low-energy flows indicate 0.8 m∙s−1 for the Sp/Sh/Sr facies, to the lack of flow (Fm). The sedimentary sequences confirm the existence of a fan, which may have originated as a subaqueous steep coarse-grained fan in glacial-flow-lake-outburst floods that formed between the ice sheet front and the morphotectonic edge of the Sudetic Marginal Fault line and within the Roztoka-Mokrzeszów Graben, or as an aerial, piedmont fan on the Sudetic Marginal Fault edge. The sediments show discontinuous deformations – gently sloping faults and fractures from glacioisostatic stresses. The fault activity is probably related to the reactivation of the faults due to ice loading during or after the older Saalian glaciation.

“…The unnamed boulder (Figure 7), located on the western, forested shore of the Głęboczek Wielki Lake (52°42'06.9"N 17°48'10.7"E), is the indicator erratic boulder -Åland rapakiwi granite -with characteristic feldspathic ovoids and round quartz crystals (Czubla et al, 2006). Its dimensions are: length -1.2 m, width -0.9 m, height -0.8 m. The following conversions are: volume -0.45 m 3 , weight -4.2 tonnes.…”

The aim of the work is to examine the possibilities of developing geotourism in the context of existing, but not yet recognised, geoheritage in the north-eastern Wielkopolska, western Poland. Pałuki is characterised by exceptional geodiversity, which has enormous potential for diversifying the present tourist offer. The valorisation method of selected 12 geosites was used, taking into account geomorphological, additional and utility categories. The results of the analytical part made it possible to identify the most valuable and geotouristically attractive geosites. They form two original geotourism trails under the common name of "Geodiversified Pałuki". In order to increase the possibilities of developing local geotourism, two proposals for thematic geotourism trail focusing on the most interesting, and highly rated, geosites in the research area are presented.

“…It is also very unlikely that it was transported from remote regions -from the Baltic Basin -area of the alimentation of the Scandinavian ice sheets. Wallstein type flints -representing lower stratigraphic units of the Upper Cretaceous and considered as indicative of this region -have diagnostic features differing from those of Rejowiec flint (Czubla 2015). The features and frequency of raw material occurring in Lechówka are generally similar to those present in chronologically and genetically diverse glacial sediments from Poland -their proportion in coarse-clastic fraction >20 mm in tills, flow diamictons and glacifluvial sediments does not exceed several percent (Górska-Zabielska 2008, Czubla 2015.…”

Flints of the Chełm Hills (Rejowiec flints) – origin, sedimentation environment and exploitation in prehistory – a case study from the Lechówka site

Rejowiec flint from the Chełm Hills occur among glacigenic sediments of the Odranian glaciation and is referred to as erratic flints. The authors, based on the analysis of the sedimentary succession of a kame in Lechówka – within the boundaries of the largest outcrop, in so-called ‘Region I’ (Rejowiec region) – indicate that: (1) the probable source of the flints were older series of glacigenic sediments – from before the Odranian glaciation, (2) their great accumulation directly under the surface and – as a result – their considerable accessibility for exploitation in prehistory were caused by the ‘upfreezing of stones’ in the conditions of a periglacial environment during successive glacial periods (Odranian, Wartanian and Vistulian glaciations). The analysis of archaeological data confirmed the use of the local flints as early as in the Middle Palaeolithic and their most intense exploitation during two main periods – the final stage of the Palaeolithic and a period from the Late Neolithic to the Early Iron Age.
