Two attributes are important in the location of the Uniejów town and commune: its lying in the centre of the country (ca. 48 km west of the geometric centre of Poland) and in the borderland in different physicogeographical divisions. Uniejów is situated in the southern part of the Koło Basin near the boundaries with Łask Plateau, Sieradz Basin and Turek Plateau. In the past, the factor most important for the development of Uniejów was its location in the placewhere the Warta valley and Warsaw–Berlin valley connected because major routes running along these valleys facilitated transport and settlement. Present development of the town is connected with geothermal waters found in Lower Cretaceous sediments within Lodz Basin. The first hydrogeological well was drilled in Uniejów in 1978. This article presents the location of Uniejów within the physicogeographical, geological, geomorphological, and botanical units and on the map of Poland’s climatic conditions.

Since 2011 the authors have been researching the regional features of rural construction in the region of Kolska Structural Basin and in its vicinity. The specific nature of this region involves a high share of buildings erected from the local building stone – upper-Cretaceous limestone silica building stone. The material, common in the area about 1000 km2 in size, is used for outcropping in the region of the village of Rożniatów, the Uniejów commune, where such formations appear on the surface in the upper layer. The article presents the results of research referring to the Uniejów commune, in which there has been listed about 30% of the total of more than 2000 buildings made from limestone silica building stone. Such a considerable distribution of that material not typical of lowland facilitated the study of the technology applied in the regional rural construction, as well as the architectonic solutions used. The buildings made from limestone silica building stone represented by housing and livestock structures, barns, churches and special structures, due to their unique character, provide a very characteristic element of the local landscape. Unfortunately, from year to year the number of structures demonstrating the regional specific nature in the commune has been decreasing. The deteriorating technical condition of the buildings results in launching maintenance works where the stone is replaced with today’s building materials. More and more structures get demolished. It is necessary to initiate the protection of that unique heritage of material culture. In such actions a special role should be played by local government.

Stanowisko Koźmin Las zlokalizowane jest na obszarze dobrze rozpoznanym w trakcie studiów geologicznych i geomorfologicznych prowadzonych przez badaczy z ośrodka łódzkiego od lat 90. ub. wieku w odkrywkach węgla brunatnego Kopalni Węgla Brunatnego „Adamów”. Od 2010 roku realizowane były tutaj wielowskaźnikowe badania nad znaleziskiem kopalnego lasu ze schyłku późnego vistulianu. Pozostałość in situ bardzo dobrze zachowanych szczątków drzew z tego okresu jest rzadkością w skali europejskiej. Uzyskane wyniki stały się podstawą wniosków paleośrodowiskowych i paleogeograficznych.

Koźmin Las site is located in the well recognized area during the geological and geomorphological studies con-ducted since 90s of the last century in the ocucrops of the Adamów JSC Lignite Mine in Central Poland. Since 2010 have been undertaken multiproxy investigations on the sediments with relicts of former riparian forest dated back at the Vistulian Lateglacial. Well-preserved tree trunks and in situ stamps from this period are rare on a European scale. Obtained results were the basis of palaeoenvironmental and palaeogeographical conclusions

The article analyses the southern part of the expansion of the Bzura-Ner Spillway (Bzura-Ner Pradolina), called the Koło Basin as well as neighbouring areas of the Łask Upland Plain and the Turek Upland Plain. The purpose of the study was to present the role of Pleistocene glaciations, especially the Warta Glaciation and, in particular, their role in the evolution of land relief in this area. It was noted that morphological activity of continental glaciers depended on morphology, lithology and dynamics of the bedrock. Special attention was paid to effects characteristic of the transgression and disappearance of the Warta ice sheet. A survey of geological and geomorphological literature, analyses of archival data, mainly the accounts of geological drillings as well as results of geomorphological and palaeogeomorphological research constitute the basis for the presented data and views. It was found that successive continental glaciers had reduced height differences of the Pleistocene bedrock without obliterating the main forms in the area. Despite the genetic diversity of forms, postglacial forms and sediments – which emerged during the glaciation of the Warta (the last glaciation in this area) – play a predominant part in the described area. The features of glacial tills and fluvioglacial and limnoglacial sediments which form Wartian mounds, hills, and ridges prove that at the end of the Warta glaciation, during deglaciation (in the Bzura sub-phase), the dynamics of glacial processes was intensified. Accumulation of ice in the lower part of the current Koło Basin was conducive to increased dynamics of the ice lobe through oscillations and, possibly, through glacial surges. However, activity of the ice sheet edge has been blurred as a result of areal deglaciation, which is documented by numerous kames – the most widespread convex glacial forms in the area.
