Opis:: The manuscript presents fossil records of Riccia spores in the Quaternary deposits. They are rarely reported and identified to the species level during routine pollen analysis. In the available sequences 5 species, including R. cavernosa, R. beyrichiana, R. sorocarpa, R. crinita and R. bifurca were noted. The occurrence of spores in fossil records proves the existence of temporary wet habitats characteristic both for natural environments (e.g. temporary dry lake shores or peat bogs) as well as habitats resulting from human activity, e.g. microhabitats in crops and pastures or trench walls. The spores recorded in sequences present an opportunity for discussion of their potential use as proxies in palaeoenvironmental reconstructions

Opis:: During many years’ research, the stratigraphy of Quaternary deposits in the area surrounding Konin has elaborated. In the young Quaternary strata the Eemian fossil lakeland was established and the exposed Mikorzyn section was found. Previous geological and palynological analyses of the site prove a nearly complete sequence of Eemian and Vistulian deposits. Furthermore, archival records of drill cores indicate that older interglacial sediments may also have been deposited about 10 metres deeper in this particular area. To test this possibility, a relatively deep test borehole—Mikorzyn 1 was carried out in the distance about 70 metres only. The sedimentological and palynological core analyses prove the Eemian age of examined organic materials. The borehole, established only the presence of ca.10 m offset in the bottom part of the Eemian strata. This fact, as well as other faults and Tertiary coal injections into glacial sediments, confirmed the occurrence of neotectonic activity.

Opis:: The paper presents characteristics of the Pleistocene sediments in the western part of the Holy Cross Mountains. They are subdivided into four complexes and their stratigraphic setting is referred to the updated scheme for the Pleistocene of Poland. The Preglacial Complex includes fluvial sediments characteristic for its lack of Scandinavian material. Sediments of three main glaciations (Nidanian, Sanian 1 and Sanian 2) within the South Polish Complex, are referred also as the South Polish Glaciations. The oldest of these glaciations (Nidanian) is separated from the middle glaciation (Sanian 1) by sediments of the Podlasian Interglacial, represented by clay at the Kozi Grzbiet Cave that contains faunal remains and record of the Brunhes/Matuyama palaeomagnetic boundary. During the middle (Sanian 1) and youngest glaciation (Sanian 2), the Holy Cross Mountains were almost completely covered by the Scandinavian ice sheet, forming glacial deposits separated by fluvial series of the Ferdynandovian Interglacial. The Middle Polish Complex begins with sediments of the Mazovian Interglacial, represented by a pollen record from the Zakrucze site. They are followed by deposits of periglacial and fluvial origin of the Liwiecian Glaciation, Zbójnian Interglacial, Krznanian Glaciation and Lublinian Interglacial. The following glaciation (Odranian) is represented by the youngest glacial deposits that document presence of the Scandinavian ice-sheet in the westernmost part of the Holy Cross Mountains. The North Polish Complex is composed of a climatic warming (Eemian Interglacial) and cooling (Vistulian Glaciation), and is represented by valley and periglacial deposits. The last cooling of the Pleistocene is recorded in faunal remains in the Raj Cave.

Tytuł:: Recent hydrogeological situation of the Kock–Ryki area (Południowopodlaska lowland)
Aktualne warunki hydrogeologiczne obszaru Ryki-Kock (Nizina Południowopodlaska)
Autorzy:: Mioduchowska, Wiktoria
Opis:: Terenem badań pracy licencjackiej był obszar Kock–Ryki położony w obrębie Niziny Południowopodlaskiej. W celu określenia aktualnej sytuacji hydrogeologicznej tego terenu i sporządzania mapy zalegania zwierciadła wód podziemnych przeprowadzone zostały badania terenowe które wykazały, że najniżej zwierciadło wód pierwszego poziomu wodonośnego zalega 114,86 m n.p.m, najwyżej zaś 188,46 m n.p.m., natomiast średnio zalega 148 m n.p.m. W 30 z 34 punktów pomiarowych poziom wód pierwszego poziomu wodonośnego nie był głębiej niż 4 m p.p.t. W pozostałych czterech punktach pomiarowych głębokość wahały się pomiędzy 4,15 a 16,45 m p.p.t. Studnie te znajdowały się w obrębie czwartorzędowych polodowcowych, słabo przepuszczalnych glin zwałowych oraz mułków piaszczystych.
The area of research for the bachelor's thesis was the Kock–Ryki region located within the Południowopodlaska Lowland. Field investigations were conducted to determine the current hydrogeological situation of this area and to create a map of the first water-bearing horizon. The research published the following results: the lowest level of the first water-bearing horizon was 114.86 m a.s.l., while the highest was 188.46 m a.s.l., and the average was 148 m a.s.l. In 30 out of 34 measurement points, first water-bearing horizon did not drop lower than 4 m b.g.l. In the remaining four measurement points, these values ranged from 4.15 to 16.45 m b.g.l. These wells were located within quaternary glacial deposits of poorly permeable clay and sandy loams.

Opis:: The Białowice site is situated in the north-west of the Nowa Sól Depression which is part of the Central Poland Lowlands. Palynological analysis shows that lake and swamp accumulations took place in the Early Vistulian. Two warm interstadial-rank oscillations (Brörup and Odderade) and a stadial (Rederstall) have been distinguished during the Early Vistulian. The sequence of changes at Białowice is similar to the sequences in profiles from other parts of Poland and Western Europe. Until now, in that region of Poland the vegetation succession of the Brörup and Odderade had remained unknown. The lithology of the profile at Białowice shows rapid changes of sedimentation which have been observed in the younger part of the Brörup and at the Brörup/Rederstall transition. Geological and palynological data suggests that the maximum limit of the Vistulian Glaciation to the south of the Żary Hills.

Opis:: The risk of dangerous radon emissions in Estonia is high, being among the highest in Europe. In almost 33 per cent of Estonian land area, the content of radon in soil-contained air exceeds the safe limit for unrestricted construction (50 kBq/m3). In such high radon-risk areas the concentration of radon in soil-contained air ranges from 50 to 400 kBq/m3, in a few cases reaching up to 2,100 kBq/m3 exceeding the permitted level for residential areas. The situation is particularly serious in the northernmost part of the country, where uranium-rich graptolite argillite (Dictyonema shale) and the Obolus phosphorite are close to ground surface and their particles are constituent parts of Quaternary deposits. Radon emissions from bedrock have been investigated in detail, but to date Quaternary strata as a source of radon emissions are poorly studied. According to our measurements the highest concentrations of radon are related to tills containing clasts and fines of graptolite argillite and phosphorite. Glacial deposits include also granitoidal material, containing U, Th and K, which have been transported by glaciers from the outcrop areas of crystalline basement rocks in Finland and the Gulf of Finland. Due to weathering, outwash and repeated redeposition other genetic types are poorer in radioactive elements and they are weaker sources of radon.

Opis:: The Ground Penetrating Radar (GPR) measurements presented in this paper had two main objectives. The first was to analize the possibility of using GPR method in examination of sediments in a mountainous geological environment and the second objective was to assess the special distribution of post-glacial sediments and their thickness at a selected site. The experimental measurements were carried out on in the alp of Ornak in the western part of Tatra Mountains This article provides a brief theoretical analysis of possible use of the georadar method in post-glacial sediment examination. The results of GPR surveys done in the reflection profiling mode enable the distinction of zones with different amount of till, clay, sand, gravel and rock debris in the post-glacial sediments.
Badania GPR prezentowane w artykule miały dwa cele: pierwszym było określenie możliwości zastosowania metody GPR do badania utworów osadowych w górskich warunkach geologicznych, a drugim - określenie przestrzennego rozkładu i miąższości utworów postglacjalnych w wybranym miejscu w górach. Badania eksperymentalne przeprowadzono na hali Ornak we wschodniej części Tatr. W artykule zamieszczono krótką dyskusję teoretyczną na temat możliwości zastosowania metody georadarowej do badania osadów postglacjalnych. Zaprezentowane w artykule wyniki badań GPR wykonanych w technice refleksyjnej pozwoliły na wyróżnienie w osadach postglacjalnych stref z różnym nagromadzeniem glin, piasków, żwirów oraz odłamków skalnych.

Opis:: Geological mapping works, conducted on 1:50,000 litho-petrographic map sheets of the South Baltic coast and the eastern part of the Pomerania Lakeland, show a clear relationship between large landforms of this area, like: subglacial channels, Wieżyca Hill, the ice lobe that accumulated Gardno moraine deposits, and sub-Quaternary relief. These landforms came into existence as a result of reactivation of pre-existing fault zones in the sub-Cainozoic basement, due to the ice mass loading during successive Pleistocene ice-sheet advances. Subglacial channels developed and thick tills and ice-dammed lake deposits were accumulated in the region. The subglacial channels and morainic belts are now dominating landforms in the Pomeranian Lakeland.
