Opis:
The research area is located in the Bytów District (NW Poland). The following analysis were performed: thickness of the humus horizon, reserves of humus, soil reaction, the acid and alkaline cations in soil adsorbtion complex and hulk density. The conducted researches revealed that the application of agricultural machinery caused erosion acceleration, particularly in the hilly areas. The deluvial horizons of these areas reach thickness of 50-100 cm. They are richer in organic matter than humus horizons located on flat-topped mountains and slopes. Discussed deluvial horizons are also characterized by less acid reaction, sometimes even neutral, and higher saturation of the soil adsorbtion complex. It was also observed that longstanding mechanization of agriculture leads to formation of a densified layer at the depth of 30 cm. The intensive fertilization with mineral fertilizers, especially nitric ones, causes soil acidification.

Opis:
The southern extreme location and the natural landscapes, highly modelled by glaciers during the Quaternary period, give Tierra del Fuego a unique opportunity to attract visitors worldwide. Its glacial landforms are geodiversity resources that are witness to global climate changes as natural processes. Therefore, this study aims to highlight different glacial landforms considering their geodidactic potential for educational information in terms of geographical study. Sixteen georesources connected by routes are analysed, using bibliographic research, fieldwork and a datasheet designed ad-hoc. Four of them were formed during middle Pleistocene glaciations and the other twelve during the Last Glacial Maximum (LGM), out of which two also represent the Holocene, which happens to be the youngest glaciation.

Opis:
The idea of establishing the Post-Glacial Land of the Drawa and Dêbnica Geopark emerged on the initiative of the members of Polish Geological Institute – Pomeranian Branch of the National Research Institute and local authorities. At the beginning of the year 2011, commissioned by the Minister of the Environment by the funds of the NFEP&WM, launched works intending to establishment of the Geopark of the Post-Glacial Land of Drawa and Dębnica. The major intention of the concept was researching and demonstrating the 50 geosites covering the Post-Glacial Land and their integration into a consistent network, establishing fundaments of the geopark. The geopark consists of the lands between Połczyn-Zdrój, Barwice and Czaplinek and is positioned in the eastern part of the Zachodniopomorskie voivodenship. The geopark is located inside the early post-glacial landscape, with dominant form of undulant moraine uplands with: terminal moraines, dead ice moraines, kemes, tunel valleys, ice-marginal valleys, kettle holes and sandurs. The geotouristic potential of the region focuses on the early postglacial landscape, and its biggest beauty the shape of the terrain.

Opis:
This research is focused on a small kettle hole located within the Morąg moraines (Iława Lake District, NE Poland). The study objective was to determine the impact of palaeoenvironmental changes in sedimentation and properties of sediments filling the bottom of the kettle hole. Sedimentological, geochemical, and palaeobotanical studies enabled us to distinguish several development phases of the kettle hole, and cluster analysis performed on physicochemical data yielded seven local geochemical zones (JuI/I to JuI/VII). The beginning of biogenic sedimentation in the conditions of a small water body, functioning in the Late Glacial period (4.20–4.10 m), was determined on the basis of palaeobotanical research. Sediments deposited in the lake during its further evolution were rich in microelements such as Ca, Na, Mg, and K, and to a smaller extent – Fe and Mn (JuI/I–III local geochemical zones). The Late Glacial lacustrine period ended with the accumulation of very silty, pollen-free gyttja, with a stratigraphic hiatus (JuI/IV, 3.40–3.20 m). The sediments were enriched with SiO2ter, which indicates an increased rate of slope erosion, and concretions of Fe-Mn occurring below this layer (JuIII) provide evidence for lowering of the water level and even desiccation. In the Holocene, the lacustrine period ended with the accumulation of coarse detrital gyttja (3.20–2.60 m). Palaeobotanical data indicate that the next group of sediments were deposited in the Late Subboreal and Subatlantic periods (2.60–0.0 cm, JuI/V–VII; sedge peat). Their properties were varied and related to hydrologic conditions, limited denudation, and vegetation succession. There was also a significant change in the trophic conditions of the water and consequently in the sediments of the kettle hole, which changed during the lacustrine period from basic to acid, and strongly acid in the surface layer. This reaction may be related to a change in the water regime as well as to human impact in the environment, which led to the colonization of the peat bog by Sphagnum moss.

Opis:
There is evidence, hitherto often denied, for the ice marginal features, including the end moraine hills along the Silesian Rampart, SW Poland. These end moraines are attributed to the regional advance of the Wartanian ice sheet into its maximum position, which is also marked by subglacial till bed. The end moraine hills are located on the northern slopes of the Silesian Rampart and they are very rare, partly due to subsequent erosion, but mainly due to conditions not favourable for a remarkable proglacial accumulation. The Wartanian end moraines of southwestern Poland possess several features that suggest that they are end moraines with dominant waterlain, stratified sediments. They are interpreted as alluvial fans, where the ice margin is represented by a 'scarp'. They have semi-conical form, often plano-convex geometry and an average distal slope of 2-25°. These fans are equivalent to sheetflow-dominated or 'humid' alluvial fans in non-glacial environments. Sedimentary sequences of the end moraines consist mainly of coarse-grained material, with boulders up to 1.8 m in diameter, with typical sediments of 'proximal fan' with a highly pulsatory water discharge. The formation of the end moraine followed the formation of a proglacial lake and strong erosion after its drainage. The end moraine was formed during oscillation of the ice margin that resulted in local glaciotectonic deformation of the end moraine fan sediments (push) and a set of parallel hills, with successive younger alluvial fans (retreat).

Opis:
W artykule krótko opisano budowę geologiczną Litwy i związane z nią formy krajobrazowe. Krajobraz Litwy został ukształtowany niemal wyłącznie poprzez procesy glacjalne i fluwioglacjalne. Na powierzchni występują zatem głównie osady czwartorzędowe. Wychodnie skał starszych (dewonu, jury, kredy i neogenu) są stosunkowo nieliczne. Pomimo braku gór, geomorfologia Litwy jest urozmaicona; o różnorodności krajobrazu decyduje obecność wzgórz morenowych łagodnych równin, szerokich dolin rzecznych i głęboko wciętych, bystrych rzek, a także wielu jezior. Jednym z najciekawszych regionów Litwy jest znajdująca się na liście UNESCO Mierzeja Kurońska, stanowiąca piaszczysty wał z najwyższymi w północnej Europie wydmami. Eksploatowany jest tam najcenniejszy surowiec Litwy - bursztyn. W artykule przedstawiono ponadto inne warte odwiedzenia miejsca, m.in.: birżański obszar krasowy (zbudowany z dewońskich gipsów i anhydrytów), okolice miasta Pokrój, znane z eksploatacji wapieni permu i dolomitów dewonu, a także miejsc występowania największych głazów narzutowych na Litwie.
The short characteristic of Lithuanian geology is presented, as well as the landforms which are tightly connected to the sediments. The landscape was formed thanks to glacial and fluvioglacial processes. The land is covered mainly by Quaternary sediments. The outcrops of older rocks (Devonian, Jurassic, Cretaceous and Neogeneperiods) are rather rare. Although there are no mountains on the territory of Lithuania, the geomorphology of the country is differentiated. The kinds of landscape are: morainic hills and plains, wide river valleys, as well as narrow river gullies and many of lakes. One of the most interesting places in Lithuania is the Curonian Spit placed on UNESCO's World Heritage list. It is full of sandy dunes, the highest in the Northern Europe. Moreover the Curonian Spit is famousfor the real Lithuanian treasure - amber. In the article there are also presented some more worth-seeing places, e.g.: Birżai karstarea (formed by gypsum and anhydrite rocks), Pakruojis region, well known thanks to the exploitation of Permian limestones and Devonian dolomites, and the large erratics locations.

Opis:
W pracy podjęto próbę określenia wielkości sedymentacji w dnach zagłębień bezodpływowych Suwalskiego Parku Krajobrazowego oraz rozpoznania utworów je wypełniających. Na podstawie przeprowadzonych analiz utworów zbadano wielkość i rodzaj przekształceń zachodzących w zagłębieniach bezodpływowych w holocenie. Stwierdzono w nich obecność alochtonicznych osadów mineralnych, oraz autochtonicznych osadów jeziornych i biogenicznych. Pierwszą grupę stanowiły deluwia piaszczysto – gliniaste o maksymalnej miąższości do 1m. Do drugiej zaliczono mułki i iły jeziorne o miąższości kilkudziesięciu centymetrów oraz gytie i torfy o łącznej miąższości sięgającej 9 m. Sekwencja osadów w zagłębieniach Snołda, Łuśnin, Linówek wykazała wtórność depozycji deluwiów w stosunku do akumulacji biogenicznej, która miała miejsce przez cały holocen. Gromadzenie osadów stokowych nasilało się jedynie w okresach wzrostu działalności gospodarczej na tym terenie. Duże nachylenia stoków i znaczne głębokości zagłębień bezodpływowych sprzyjają rozwojowi procesów stokowych. Materiał zdeponowany w obniżeniach pozostaje w nich unieruchomiony. Ogranicza to przestrzennie zasięg denudacji i tym samym oddziałuje stabilizująco na morfologię krajobrazu młodoglacjalnego.
The study is an attempt to determine the size of sedimentation at the bottoms of the small kettle holes of Suwałki Landscape Park as well as the deposits that fill them. The size and the type of the transformations occurring in the kettle holes during the Holocene were determined on the basis of conducted analyses. The presence of allochtonic mineral deposits and autochtonic lacustrine and biogenic deposits was affirmed. The first group consisted of loam colluvium with a maximum thickness of up to 1m. The other one contains lacustrine clays and silts with a maximum thickness of several tens of centimeters and gytjas and peats with a total thickness of up to 9 m. Sediments’ sequence in Snołda, Łuśnin and Linówek depressions indicated a secondary nature of the colluvium deposition in relations to the biogenic acumulation that took place throughout the Holocene. Hillslope sediments accumulation intensified only in times of economic activity growth in the area. Steep gradients of slopes and considerable depth of kettle holes favor the development of hillslope processes. The material accumulated in the depressions remains immobilised. This limits the spatial extent of the denudation and thus stabilises the morphology of early post-glacial landscape.

Opis:
This article analyses the characteristics of paraglacial environment that are recorded in sediments and forms, within the context of the development of views on the relief of Central Poland in the area beyond the extent of the Vistulian (Weichselian) Glaciation. The original relief of the analysed area was formed during the Warta Glaciation (Wartanian, Late Saalian). Until the 1950s, the relief was considered as glacial, when the opinion that periglacial morphogenesis had great significance was prevalent. According to the hypothesis, periglacial processes dominated the original glacial relief, until denudational periglacial plains with tors were formed. However, since the 1960s, more and more data have been documented concerning good preservation of fragments of glacial landscape, particularly within the range of kame fields. In the 1990s, a concept of polygenesis of the relief was presented, stressing the importance of periglacial environment. However, it must be noted that all views on the genesis of the area that have been presented so far still have a gap in the light of contemporary interpretation of the concept of periglacial environment. There is a need to take into account the so-called paraglacial environment, which has hardly been distinguished until now in areas of Pleistocene glaciation. According to present knowledge, the relief of the Warta belt in Central Poland should be recognised as polygenic with predominant features of old glacial relief and with elements of paraglacial, periglacial and fluvio-denudational relief from moderate periods.

Opis:
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.

Opis:
W słabo i silnie zamulonych glebach torfowo-murszowych występujących w krajobrazie młodoglacjalnym zbadano, w trzech terminach 2006 r. oraz w jednym terminie 2007 r., mineralizację organicznych związków azotu. Zawartość uwalnianego azotu mineralnego (N-NH4 i N-NO3), w badanych glebach wykazywała zmienność sezonową. W 2006 r. największa była latem, w okresie wiosennym była 3-4-krotnie, a późnojesiennym 1,5-2-krotnie mniejsza. Największe ilości N-NO3 uwalniały się w okresie letnim w glebach silnie zamulonych i w świetle liczb granicznych mieściły się w przedziale zasobności średniej. Stosunek N-NO3 do N-NH4 tylko w okresie wiosennym był większy od jedności. Zawartość mineralnych form azotu latem 2007 r., ze względu na wysoki poziom wód gruntowych, była mniejsza niż w okresie letnim 2006 r. Zawartość azotu mineralnego (N-NH4 + N-NO3) w analizowanych glebach nie wykazywała wyraźnej zależności od stopnia ich zamulenia.
Mineralization of organic nitrogen was examined in weakly and heavily silted peat-muck soils in the young glacial landscape. The study was carried out in three periods in 2006 and in one in 2007. The amount of mineral nitrogen released from the examined soils varied seasonally. The largest amounts were released in the summer 2006, whereas in spring and late-autumn periods these amounts were 3-4 and 1.5-2 times lower, respectively. In spring the N-NO3 to N-NH4 ratio was above one whereas in the summer and autumn the ammonium form prevailed. Greatest amounts of N-NO3 were released from strongly silted soils in the summer period and in the light of boundary numbers they show medium content of nitrogen. In the summer 2007 the content of mineral forms of nitrogen was lower than in the summer 2006 due to the low groundwater level. In the examined soils mineral nitrogen content (N-NH4+ N-NO3) did not depend on silting.

Opis:
The content and relationships between amounts of macroelements (Ca, Mg, K, Na and Fe) and soil properties along three catenas in the young glacial Łyna River valley, NE Poland, are discussed in the paper. The results were presented against the background of four geochemical landscapes distinguished within the study area: eluvial / trans-eluvial, eluvial accumulative, trans-super-aqual and super-aqual. The middle part of the Łyna River valley is covered with Fluvic Phaeozems and Dystric Fluvisols formed from sands, loams and silts. In some parts, Mollic Gleysols (Limnic) formed from peats and gyttja occur. In the areas adjacent to the floodplain, Eutric Umbrisols (Pantocolluvic) and Haplic Umbrisols (Colluvic) formed from loams, silts and clays are located. The upper slope of the valley is covered by Luvic Pheazems, Luvic Umbrisols, Brunic Dystric Arenosols and Dystric Arenosols The average content of macroelements reached: Cat – 6.60 g kg-1, CaHCl – 3.17 g kg-1, Mgt – 2.79 g kg-1, MgHCl – 0.68 g kg-1, Kt – 7.27 g kg-1, KHCl – 0.20 g kg-1, Nat – 0.84 g kg-1, NaHCl – 0.22 g kg-1, Fet – 8.72 g kg-1 and FeHCl – 5.48 g kg-1. Th content of macroelements in soils of the analysed area was varied between the four geochemical landscapes. The analysis, supported by PCA ordination, resulted in significant positive relations between the macroelement contents and silt (0.05-0.002 mm) and clay (<0.002 mm) soil fractions, CaCO3, pHKCl and amounts of organic matter, as well as an inverse relation to the share of sandy (2.0-0.05 mm) soil fraction. Soils in super-aqual geochemical landscape were the most abundant in macroelements (except KHCl and Nat). The most typical sites of macroelement accumulation were the following geochemical landscapes: super-aqual > trans-super-aqual > eluvial accumulative > eluvial / trans-eluvial.

Opis:
The paper describes a relief intensity factor (RIF) as a method to: 1) recognize main forms of the young-glacial landscape; 2) characterize their morphometry; 3) determine their changes due time and different conditions, as well as 4) compare forms on different altitudes. It consists of three factors: relative height RH and neighborhood NH (counted on the basis of DTM) and also a structure of forms STR – their grain composition GC and the shape FS (relied on geological maps). The model of the Pomeranian relief intensity allows to predict characteristic values for selected postglacial landscape forms. Taking into account the range of the I – III quartile, these values are as follows: for marginal lake basins – 3-6 (mean 4.25); for proglacial stream valleys – 4-7 (5.66); for outwash plains – 6-9 (7.88); for hills consisting of the glacial till (end moraines, ground moraine) and also kames and eskers – 8-12, mean 9.20-10.33 (end moraines 10-12, mean 10.52).

Opis:
Erosion strongly influences the soil properties and affects the intra-field variation of nutrients not only in steep young morainic landscapes but also on gentle slopes of old-glacial landscapes. The aim of the study was the evaluation of changes in the plant-available nutrient contents in the complex old-glacial eroded landscape of the Bielska Plain in the north-eastern part of Poland. The soil samples were collected from the soil profiles located along the transect beginning on the flat summit of the kame hummock extending through south-facing convex slope, the toeslope and footslope and further through the north-facing uniform slope. The content of plant-available forms of phosphorus (Pdl) and potassium (Kdl) and mineral forms of nitrogen (NH4-N and NO3-N) were determined in every soil profile. The soils located in various landscape positions were characterized with different fertility. In the soil located on the toeslope the content of NO3-N, Pdl and Kdl was high, while the soil located on the summit was rich in NH4-N and poor in the plant-available forms of K and P. The erosional distribution of plant-available N, P and K enhances the variation of nutrient content within one field and contributes to high variability of crops.
