Opis:
Different glaciotectonic structures and landforms occur in the territory of Belarus: folded dislocations, glacial depressions, rafts and injective features. The largest folded glaciodislocation is 30 km long and 8-11 km wide, and glacial rafts are up to 1.5 km long and 20-25 m thick. Many glaciotectonic structures are clearly expressed in landscape. Most large folded glaciodislocations were formed during the Sozh (Warthe) Stage of the Dnieper Glaciation.

Opis:
The possible existence of a circular structure in the Kościerzyna region (northern Poland) was suggested in two papers in the 1980s. The current studies were aimed at verifying this hypothesis. Analysis of a digital terrain model of the pre-Quaternary surface relief as well as of the present terrain revealed the existence of a large structure of ca. 50 km in diameter. Its geometry was established based on a model of the Neogene/Pliocene surface and identifiable lineaments. Its characteristic feature is the presence of rim-like forms, an internal plateau, and a “high” in the centre. The structure is estimated to date from before the Pleistocene. The circular structure has been reshaped by glacial erosion and accumulation, and is now buried under Quaternary deposits. The existence of the Kościerzyna circular structure was confirmed by conducted studies, but my hypothesis of an impact origin is still uncertain and needs to be confirmed by future research.

Opis:
Mollusc-bearing deposits at Hrud II (Eastern Poland) accumulated in the western part of a palaeolake of Holsteinian age (MIS 11). The faunal assemblage is typical of freshwater environments and presumably represents a part of the interglacial climatic optimum (Carpinus–Abies Zone). On the basis of its varied composition, the evolution of the water body is described. Reinterpretation of the data from the eastern part of the lake (Hrud I) and combining of the results from both sites enable a wider palaeoecological reconstruction. Fluctuations in lake level, water dynamics and changes in the aquatic vegetation are inferred from quantitative relations between selected molluscs, especially Lithoglyphus jahni, Valvata piscinalis and Bithynia tentaculata, which prevail in the deposits investigated. A predominance of Valvata piscinalis indicates a rise in water level, whereas the communities with abundant Bithynia opercula are typical of a more shallow lake with rich reed fields. Amelioration of the trophic conditions between the pre-optimal and optimal part of the Holsteinian Interglacial can also be recognised.

Opis:
Aerial photographs taken from kites provide a versatile and low-cost means to acquire high-resolution, large-scale imagery for special Quaternary investigations. Kite aerial photographs (KAP) are typically taken from heights of 50-150 m using light-weight automatic cameras. Pictures may be acquired in vertical and oblique vantages. Scanning of photographs and digital processing allow for resampling, enhancement, and analysis of images. We have utilized basic KAP at five sites in eastern and northern Poland in order to evaluate the potential of KAP for Quaternary investigations. Our preliminary results suggest that KAP may provide detailed and repetitive imagery of geomorphic conditions, soils, land cover/use, and other surface features related to Quaternary processes, landforms, and deposits. However, KAP will not replace conventional aerial photography for general survey and mapping purposes.

Opis:
A new investigation and palaeoenvironmental reconstruction of the locss-palaeosol sequence at Prymorskc, SW s q Ukraine is presented using soil structures, grain size, mineral magnetics, organic carbon and calcium carbonate determinations. Six units of the established Ukraine Quaternary stratigraphical scheme have been identified and analysed above and including the Zavadivka (Holsteinian) marker horizon - Dnieper, Kaidaky, Tiasmyn, Pryluky and Udai. Precipitation and temperature are tentatively reconstructed from soil and sedimentary proxies calibrated by modern analogues. Increased temperatures and precipitation to today are inferred for the red-brown Zavadivka palaeosol. Overlying Zavadivka is the Dnieper loess containing a gley and two chernozcms above, possibly representing climatic variations of the Saalian Glaciation. The calcified chernozem Kaidaky is separated by a thin loess from the brown/ chestnut Pryluky palaeosol (Eemian) which has features indicating drier conditions to the present. Non-gleyed palaeosols exhibit an enhanced magnetic susceptibility (MS) signal relative to the less weathered loess and highlights the palaeoclimatic potential of the technique. The most well developed palaeosol from this study has the highest MS value (Zavadivka: 80-1 o·8 SJ units) but this relationship is not always found in the Black Sea region. Previous MS analyses at Prymorske (Nawrocki et al. 1999) report significantly higher values to those of this study. Consequently the MS curve at Prymorske cannot be used with confidence for palaeoenvironmental reconstruction and inter-regional correlation without further investigation and modern analogue study.

Opis:
W pracy zaprezentowano na tle warunków geologicznych charakterystykę znalezionych krzemieni pochodzących z piasków szczytów wzgórz morenowych oraz z gliny zwałowej w czwartorzędowym nadkładzie pokładu węgla brunatnego w Sieniawie. Krzemienie składają się z drobnoziarnistego autogenicznego kwarcu, trudno identyfikowanej ilości amorficznego chalcedonu oraz śladowej ilości goethytu i być może moganitu. Krzemienie zawierają od 0,15 do 0,36% węgla organicznego oraz w ilościach śladowych takie metale jak mangan, stront, tytan i cynk. Trudno jest jednoznacznie wyznaczyć, które z badanych metali mogą być związane z genezą krzemieni, ich wiekiem lub taką cechą jak barwa i jej strefowe zmiany. Przypuszczalnie badane krzemienie mogą pochodzić z utworów węglanowych kredy i/lub jury występujących w północno-zachodniej Polsce lub w rejonie na północ od wybrzeża (dno Bałtyku).
In the paper, geological conditions and characteristics of found flints originated from sands and boulder clay are presented. Flints are present in Quaternary overburden of the brown coal bed in Sieniawa, Poland and they consist of fine-grained authigenic quartz, hard to identify amount of amorphous chalcedon and trace amounts of goethite and possibly moganite. Flints contain from 0,15 to 0,36% of total organic carbon and trace amount of metals such as manganese, strontium, titanium and zinc. Presumably, investigated flints may origin from Jurassic and/or Cretaceous carbonate formations occurring in the North-Western parts of Poland or in the region due north from polish coast line (bottom of the Baltic Sea).

Opis:
Several event layers have been identified in lacustrine deposits in the AErI Basin of Anatolia (E Türkiye). Sedimentological and palaeontological data newly indicate a storm-induced origin for some of them. The sedimentary structures in three sections, a few tens of metres apart from each other laterally, such as hummocky cross-stratification, wave-generated cross-bedding, parallel bedding, erosional surfaces, and graded bedding, which are considered characteristic of tempestites, are clearly present. Additionally, fining-upwards units and biogenic escape structures located at different levels of these sections indicate a similar origin. The vertical variations in layer thickness, grain size, and sedimentary structures in these sedimentary sections indicate fluctuating hydrodynamic conditions during deposition, while lateral decrease in the size and wavelength of the structures reflects deepening. This interpretation of storm-induced deposition is compatible with regional palaeoclimatological and palaeogeographical data, and is supported by evidence of Quaternary storm-induced sedimentation in adjacent lacustrine basins in the region.

Opis:
Systematic investigations of glaciotectonic features in Lithuania started in 1994. The first glaciotectonic review map of Lithuania has been carried out as a constituent part of the glaciotectonic map of central Europe. Two groups of landforms linked with glaciotectonic structures (composite ridges and massifs, drumlins and flutings) have been distinguished. Distribution of the pre-Quaternary megablocks in the Quaternary deposits is presented also, and the number of megablocks composed of rocks of different age and lithology is directly proportional to their extension in the sub-Quaternary surface. The other more detailed investigations of glaciotectonic features in Lithuania are connected with regular geological mapping in scale of 1:50 000. Results of the first detailed studies of glaciotectonic features (folds, thrust faults, diapirs) investigated in two outcrops in southeastern Lithuania and in the Lithuanian maritime region are presented in the paper.

Opis:
The sub-Quaternary topography of the western Sandomierz Basin has been compared to variable thicknesses of Quaternary sediments and geomorphology of the area. The lithology and age of the top of Miocene strata have been determined. The Witów Series has been interpreted as a sequence of a braided river that used to flow into the retreating marine basin, forming a fan delta whose age, according to macrofloristic determinations, has been assigned to the Late Miocene. Lower Quaternary gravels cap the remnants of a planated surface situated at 240-250 m a.s.l. The Błonie gravel horizon occurring at a similar altitude was deposited by a river active in Narevian and/or Nidanian glacial stages, and its top underwent reworking during the Sanian-2 stage. Deposits infilling the fossil sub-Carpathian Furrow have been mapped and dated to the Cromerian s.l. interglacial stage. The final alluviation of this segment of the furrow took place during the Sanian-2 stage. Reconstruction of the drainage pattern during the Eopleistocene, South-Polish glaciations, and Masovian inter- glacial stage has been proposed as well.

Opis:
Two types of large, branched structures from the Lower Pleistocene (Calabrian) high-energy calcarenites of Favignana Island are described: Faviradixus robustus gen. et sp. nov. and Egadiradixus rectibrachiatus gen. et sp. nov. They may be interpreted as root structures of large plants, trees and trees or shrubs, respectively. The former taxon co-occurs with the marine animal trace fossils Ophiomorpha nodosa, Ophiomorpha isp., Thalassinoides isp. and Beaconites isp. The interpretation as root structures although tentative is probable and can be related to short emergence episodes for the formation of E. rectibrachiatus or to longer emergence, responsible for the discontinuity at the base of the overlying Tyrrhenian deposits, for F. robustus. Calcified root mats of smaller plants associated with the Tyrrhenian or younger emergence surfaces are common.
