The paper presents abiotic resources which are located in a small town in central Poland. They remain unknown to authorities and inhabitants. For the first time they are illustrated in a scientific paper. The objects of local geological heritage point to geodiversity of this district town in the south-western Mazovia. When the geodiversity is interpreted in a simple, an understandable way, it may become attractive for tourists. We show how abiotic resources located within an urban area can be used to support urban geotourism development. The scientific, educational and aesthetic values of these resources may create the town image in accordance with the principles of environmental protection.

Interpretation of the regional high-resolution seismic data of the PolandSPANTM survey in the Grudziądz-Polik area revealed a new depositional architecture of the Upper Cretaceous succession that differs substantially from the previously assumed layer-cake model, commonly applied to Permian-Mesozoic sequences. A previously unrecognized regional unconformity, dividing the Upper Cretaceous succession into two units characterized by very different internal geometries, was identified and mapped. The lower unit, with a generally layer-cake internal pattern, is overlain by an upper unit composed of a regionally low-angle succession that pinches out toward the south. This newly revealed regional pattern remained unrecognized in previous regional compilations based on borehole data, which suggested that a layer-cake depositional architecture prevailed throughout the entire Upper Cretaceous. This new image of Upper Cretaceous depositional patterns has far-reaching consequences for understanding of the evolution of the Polish Basin in the Late Cretaceous, including its subsidence and burial history, deposition, and tectonic development. A re-evaluation of the chronostratigraphy of the Upper Cretaceous of the Polish Basin is needed to temporally constrain the succession of sedimentary and tectonic events revealed here.

Our high-resolution data of pollen and macrofossils from 2 cores taken from the Jagodne site (Garwolin Plain) reveals a pollen succession covering the final part of the Late Saalian (Marine Isotope Stage MIS 6) and embracing the Eemian (MIS 5e). The results correspond to Regional Pollen Assemblage Zones (RPAZ). The hornbeam phase (E5 RPAZ) has been subdivided into subzones and compared to the corresponding division of the key profile of the Garwolin Plain, Kozłów K2-19. The comparison revealed a considerable sedimentary hiatus in the E5 RPAZ at Jagodne. This is attributed to significant palaeohydrological changes occurring widely in this zone, and also seen at other Eemian sites in Poland. Another specific feature of the Jagodne site is the early, rapid terrestrialisation of the palaeolake and its transformation into a raised bog, which occurred already at the end of the hornbeam phase. The Sphagnum dominated peatbog developed for a long time as evidenced by a thick peat layer covering also the Early Vistulian. Both pollen and plant macrofossil data correspond well to observed lithological boundaries, providing a consistent record of palaeoenvironmental and palaeoclimate changes. The results obtained contribute to knowledge of palaeoenvironmental changes and palaeoclimate interpretation of that area.

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.

Site 15 in Mąkolice, Głowno commune, is located in central Poland, on the Łowicz-Błonie Plain. The majority of obtained archaeological sources are related to the settlement of the population of the Przeworsk culture. The most interesting features include relics of structures of two post buildings – a long house and an accompanying building, discovered in the southern part of the settlement. The most important stage of the settlement can be linked to the C2 – D1 phase.

The aim of our study was to quantify the differences in the regeneration-degeneration processes in pine and mixed oak-pine forest habitats in the Kampinos Forest (central Poland). We investigated whether the regeneration rate depends on habitat type, whether there is a relationship between the bilberry (Vaccinium myrtillus) cover and the degree of community deformation, and which habitat type has been most invaded by alien plant species. Our results indicate that the constant loss of pine forest habitats, which has been observed since the 1970s, is continuing. The less deformed communities generally have more bilberry coverage, the stands in pine forest habitats are older and less deformed, and the stands in mixed oak-pine forest habitats are more susceptible to the spread of alien species, but are able to regenerate faster after a disturbance. These results are in line with observations from other parts of Poland and other European countries.

The petrographical features of the medium- and coarse-grained gravels (4-10 mm and 20-60 mm, respectively) of weathered and fresh (unweathered) deposits indicate, in combination with so-called indicator and statistical erratics, that two glacial lobes joined in the borderland of the Polish Lowlands and Uplands. Lower Palaeozoic limestones become less frequent in the finer gravel fraction, whereas crystalline rocks and flints become more frequent. The petrographical analysis of the coarser gravel fraction indicates that the ice sheet advanced from the NE to NNW (the Widawka lobe) and from the NE to ENE (the Rawka, Pilica and Luciąża lobes). The source areas of the gravel deposited by the Warthian ice sheet were magmatic and sedimentary areas of both the Baltic and the SE Sweden basins.

The 1st Middle-Polish (1st Lusatian) Lignite Seam is exploited in open-cast mines in central Poland. A large number of lignite lithotypes, grouped in four lithotype associations, are distinguished: xylitic, detritic, xylo-detritic and detro-xylitic lithotype associations, which show various structures. Each lithotype association was produced under specific peat-forming environmental conditions. In the case of the lignite seams under study they represent all the main environments that are known from Neogene mires, i.e.: fen or open water, bush moor, wet forest swamp and dry forest swamp. For a simple and practical description in the field of both the lignite sections and borehole cores, a new codification for lignite lithotypes is proposed. It is based on the codification of clastic deposits (lithofacies). The practical value of the new lignite lithotype codification is examined in three vertical sections of the 1st Middle-Polish Lignite Seam.

The heavy-mineral assemblages of Pleniglacial fluvial sediments were analysed for two river valleys, viz. the Luciąża River (at Kłudzice Nowe) and the Belnianka River (at Słopiec). These sites, on the Piotrków Plateau and in the Holy Cross Mountains respectively, are located in different morphogenetic zones of Poland that were affected to different degrees by the Middle Polish ice sheets. The study was aimed at determining the kind of processes that modified the heavy-mineral assemblages in the two fluvial sediments, at reconstructing the conditions under which these processes took place, and in how far these processes caused changes in the assemblages. The heavy-mineral associations of the parent material was taken as a starting point; this parent material were the sediments left by the Odranian glaciation (Warta stadial = Late Saalian). It was found that heavy-mineral assemblages in the Luciąża valley deposits are varied, particularly if compared with other fluvioglacial Quaternary deposits from the Polish lowlands, with a dominance of garnet. In the fluvial deposits of the Belnianka valley, zircon, staurolite and tourmaline dominate, with minor amounts of amphibole, pyroxene, biotite and garnet. This suggests that the deposits were subject to intensive and/or persistent chemical weathering and underwent several sedimentation/erosion cycles under periglacial conditions. In both valleys chemical weathering and aeolian processes were the main factors that modified the assemblages of the transparent heavy minerals; these processes were largely controlled by the climatic changes during the Pleistocene.
