Opis:
The article focuses on multicomponent system separation with the use of an innovative membranebased technique i.e. pervaporation. Pervaporation is a membrane technique for separation of liquid mixtures on solid nonporous membranes. Pervaporation is used in this study to separate a quaternary system acetone-butanol-ethanol-water. Such a system may be derived from ABE fermentation process, and the resulting product, biobutanol, is a potential biofuel and may be used in internal combustion engines. Experiments in the study involving concentration of butanol by pervaporation were performed using PERVAP 4060 flat-sheet commercial membrane. To describe the PV process a semi-empirical approach was used. As a result of experiments and calculations permeance coefficients were obtained. Separation and permeance factors were calculated to assess the efficiency of the system separation. Beforehand, activity coefficients were determined for all the components of the mixture with the NRTL equation. Separation coefficients for all the components differed depending on process parameters: concentration, feed flow rate and process temperature. The study confirmed the separation effect of the quaternary system. The most interesting results were obtained for the concentration of butanol. Pervaporation allows to concentrate butanol over 10 times. The permeance coefficient reached for butanol an average value of 7.06 10-3 in comparison with the results for ethanol 3.24 10-2 and acetone 1.83 10-2 [kmol(m2h)-1]. The temperature change from 50 to 70 [degrees]C led to an increased permeance factor and there was no apparent effect on it in the feed flow rate. Due to the hydrophobicity of the membrane water fluxes in the quaternary system were negative.

Sub-Quaternary buried relief between Wieprza and Łupawa rivers in northern Poland has been subject to geological research, by means of analysis of geological maps indicating sub-Quaternary morphology. For comparative analysis, maps prepared within the Detailed Geological Map of Poland 1:50,000 project and maps executed by the present author in identical scale have been used. The course of sub-Quaternary depressions on either maps shows discrepancies. Five genetic types have been distinguished, although their polygenesis is inferred. The oldest sub-Quaternary valleys are of late Cretaceous age and their origin had been influenced by Alpine tectonics. In the Tertiary, a valley system with north-and north-west-oriented drainage developed, with the base-level along the axis of the present-day Baltic Sea. During Pleistocene glaciations the older relief was covered by glacial and glacifluvial deposits. The sub-Quaternary depressions are important water suppliers for local people. In addition, an attention has been paid to the age and source of ice rafted material, as well as to the timing of their deposition, as these are important constraints in the Pleistocene stratigraphy. Ice rafted material from Możdżanów and Krzywań has special economic importance, bearing amber and phosphates, respectively.

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.

With the use of the differential thermal analysis (DTA), studies of the phase transitions were conducted for 90 of alloys from the quaternary Bi-In-Sn-Zn system and for the constant ratio of Bi:In and Bi:Sn. The studies were conducted for the alloys prepared from the purity metals (Bi, In, Sn, Zn = 99.999 mas. %) by way of melting in a graphite crucible in a glove-box filled with Ar, in which the impurities level was less than 0.1 ppm. After melting and thorough mixing, the liquid alloys were poured out into a graphite test mold. The phase transition temperature data obtained from the DTA investigations were next confronted with those determined from the calculations based on the binary and ternary optimized thermodynamic parameters available in the literature. It was found that the experimental and the calculated phase transition temperatures were in good agreement.

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.

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).

In this study, the corrosion performances of ammonium copper quaternary (ACQ) and boric acid (BA) wood preservatives were investigated, with micronized copper quaternary (MCQ) and nano boron (NB) used as reference materials. In the study, Scots pine (Pinus sylvestris L.) wood samples were impregnated according to the full-cell process method with ACQ at 2.4% concentration, BA at 4% and MCQ and NB at 1%. The ACQ- and BA-impregnated samples were then impregnated for a second time using five different water-repellent materials: tall oil, linseed oil, sodium silicate, methyl hydrogen silicone and N'-N-(1,8- naphthalyl)hydroxylamine. Polyethylene glycol (PEG) 600 and aluminum sulfate were introduced as single impregnations in the form of homogeneous mixtures with ACQ and BA. The corrosion properties of the impregnated and control samples, including metal weight loss (MWL) and corrosion depth, were examined. The MWL values of the ACQ-impregnated samples showed an increase compared to the control group. The MWL values of the MCQ-impregnated samples were lower than those of the samples impregnated with ACQ, whilst the MWL values of the BA-impregnated samples were higher than those of the samples impregnated with NB.

Opis:
The East Carpathian Foothills of Poland witnessed two episodes of relief planation in the Pliocene, followed by formation of Early Pleistocene strath terraces preserved on flat-topped meander spurs in the San River valley at altitudes of 100-120 m above recent floodplains. In the following stages, intense erosion produced of a flight of strath terraces that are provisionally dated to the Narevian or Sanian-1 (Menapian or Elsterian-1; 75-80 m), Sanian-2 (Elsterian-2; 40-60 m), Odranian and Wartanian (Drenthe, Warthe; 20-30 m), and Vistulian (Weichse- lian; 8-16 m) times. During glacial stages, solifluction deposits mantled the feet of gentle slopes being coeval with fluvial deposition and accumulation of loesses and loess-like sediments on either side of the San River valley, particularly intense in the Weichselian. Interglacial warmings fostered downcutting of the pre-existing fluvial sediments as well as formation of fossil soils within loess sequences and deposition of peat in abandoned channels. In the Late Pleistocene and at the beginning of the Holocene, diversified tectonic movements took place leading to displacement of Weichselian and Holocene straths. During the Holocene, in turn, cut-and-fill terrace steps were shaped, organogenic sediments filled abandoned channels and oxbow lakes, and slopes became re-modelled by landslides and slopewash. The pattern of different types of relief, together with spatial distribution of topolineaments and some photolineaments in the eastern portion of the Polish Outer Carpathians, has been shaped due to mutual interactions between climatic, lithologic and tectonic factors. Well-pronounced topolineaments either follow fault-related zones of weakness, are associated with dense network of extensional cross-fold joints, or indicate recent reactiva-tion of some faults and/or joint sets.

Opis:
Geological boundaries of the structural stages between Late Variscan Moravian-Silesian-Cracow orogene and Saalian Sławków Graben taphrogene, Early and Late Kimmerian epeirogene, Middle Alpine Silesian-Cracow Monocline, and Late Alpine Carpathian Foredeep are defined as discordances. These structural surfaces of different age, present in the top surface of Carboniferous deposits of the Upper Silesian Coal Basin, were investigated in morphotectonic research. Discordances in the morphotectonical record separate older faulted and folded Carboniferous deposits from younger, nearly subhorizontal rocks of epi-Variscan cover. This polychronic and polygenetic geological heterochronous boundary of the top surface of Carboniferous deposit consists of the following coeval discordances: sub-Permian, sub-Triassic, sub-Jurassic, sub-Cretaceous, sub-Miocene and sub-Quaternary. Those buried erosional surfaces with ancient landforms were some formed by terrestrial, others by marine planation. The repeated erosion of Carboniferous deposits and sedimentation of covers as well as fault, monocline and fold-flexure deformations are reflected in differentiated configuration of discordances in the height range from about 400 m a.s.l. to 6000 m b.s.l.

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:
Pathogenic microorganisms like fungi, bacteria and algae are harmful to human beings and animals. Moreover, they contribute to the destruction of building materials by their biodegradation. Therefore, they create serious hazard for the natural environment. To prevent these phenomena, different materials with biocidal activity are being developed. In elaboration of such materials, one of the most difficult problems to be solved is the achievement of their high effectiveness in controlling harmful microorganism population with the guarantee of safety of their application to the natural environment and humans. As a result of investigation carried out in the INCT on new biocides based on quaternary N-alkylammonium salts (QAC), mainly benzalkonium chloride, and water glass (WG) large group of new silica materials with biocidal activity were synthesised. Possibilities of technology modification in order to obtain different profitable properties of materials are presented in the paper. Preliminary investigations concerning biocidal activity against selected mould fungi, bacteria and algae were performed. Results of microbiological investigations proved stable effectiveness of biocides for protection from harmful microorganisms growth, which does not decrease even after washing of biocidal material with water. Silica materials with biocidal activity due to structural binding of biocidal agent (QAC) can be applied in building industry as materials of high ecological safety.

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.

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.

We report 44 mollusk species from four Pliocene to Pleistocene seep deposits in Leyte Island, Philippines. The bivalves are represented by 30 species, of which eleven are new (Conchocele majimai, Conchocele visayaensis, Channelaxinus antipoloensis, Dulcina liogliogensis, Dulcina magoi, Elliptiolucina fernandoi, Lucinoma canudai, Lucinoma velosoi, Lucinoma tinagoensis, Lucinoma kosatorea, Archivesica pastori), six are extant species known from the Philippines and surrounding waters (Meganodontia acetabulum, Lucinoma dulcinea, Lucinoma aff. kastoroae, Vesicomya margotae, “Pliocardia” ticaonica, “Pliocardia” indica), and five are extant species known from Japanese waters (Bathymodiolus securiformis, Divalucina soyoae, Archivesica kawamurai, Pliocardia kuroshimana, Elliptiolucina ingens). Remarkable about those latter species is that only a single one of them occurs as fossil in Japan, despite Japan’s rich fossil record of seep communities. This together with the large number of new species with close relatives in Japan suggests that at least part of the modern Japanese vent and seep fauna originated in Philippine waters. More than one third (twelve) of the bivalve species reported here belong to the family Lucinidae, which is also very species-rich in shallow waters around the Philippines. Four new gastropods are described: Margarites hayashii, Vetulonia philippinensis, Cataegis ramosi, and Provanna azurini.

Among the Quaternary deposits of the Beskid Mały and Beskid Makowski Mts. in southern Poland, loess-like silts occurring in the Skawa River valley and the Paleczka River valley are distinguishable by their high loess index values as well as by the presence of amphibole grains and by notable amounts of biotite grains. These silts originated by aeolian sedimentation during the younger Pleniglacial of the Vistulian, corresponding to the Younger Upper Loess. The amphibole and most of the biotite was derived from deflation of a glaciofluvial cover in the Carpathian forelands and Fore-Carpathian basins. They indicate the importance of northern winds in the Plenivistulian atmospheric circulation.

The stratigraphy and lithology of the Quaternary deposits of the Kleczew region are analysed in a regional context. They can be correlated with the Preglacial, Narevian(?), South Polish, Middle Polish and Vistulian Glaciations, and the Podlasian, Zbójno and Eemian Interglacials. Large glaciotectonic structures, commonly encountered in lignite mines, proved useful in correlating grey tills of the older Pleistocene glaciations. Lithology, stratigraphy, thickness and palaeomorphology of the Pleistocene sediments were presented in the key sites Konin-Marantów, Mikorzyn, Sławoszewek and in 6 borehole sections. A regional lithostratigraphic scheme of the Quaternary in the eastern Wielkopolska Lowland was constructed basing on petrographic coefficients of tills, lithology, genesis and, finally, on hypsometric setting and thickness. In the light of these studies the maximum ice sheet unit of the Oldest Glaciation should be moved to the south from Kleczew. Moreover, tills of the Odranian, Wartanian and Vistulian Glaciations were found.

Opis:
Results of a microgravity survey performed in the abandoned Starunia ozokerite mine (Carpathian region, Ukraine), where in the early 20th century well preserved remains of large, extinct mammals were found, are discussed in the paper. A number of gravity anomalies indicating the geological heterogeneity at the sub-Quaternary strata have been observed. The assumed measurement observations also enabled the authors to interpret the results in view of density changes in the Quaternary strata. Most of the registered microanomalies coincide with the high-halite and ozokeritic Miocene salt-bearing Vorotyshcha beds. The distribution of the microanomalies reveals neither their correlation with the thickness of overburdens, nor any gravity impact of numerous abandoned wells. Gravity anomalies were mostly connected with the lithology of sediments and rocks obtained from geological boreholes drilled in the years 2007 and 2008, on the basis of which the anomalies' origin could be determined. A concentric, relatively negative gravity microanomaly of ca. 25 m in diameter was registered in the place, where very well preserved relics of the woolly rhinoceros had been found. They may be indicative of the existence of Pleistocene lakes (and/or palaeoswamps), into which the woolly rhinoceroses had sunk. Hence, an assumption can be made that the further search for successive zoological relics can be made in areas with similar anomalies under the low-density sub-Quaternary subcrop.

Opis:
This paper presents the results of a detailed analysis of flysch-derived clasts within Quaternary fluvial gravels exposed close to a map-scale overthrust. These clasts are commonly fractured. For a given population of clasts, the number of fractured clasts is positively correlated with the clast size and negatively correlated with the grain size of clast-forming rocks. The fractures comprise both those inherited from earlier joints cutting source strata, and those formed in situ within the gravels (neofractures). These two groups of fractures show different diagnostic features. The inherited fractures are orientated at random in relation to geographic coordinates, where as the neofractures show a well-organized architecture. The inherited fractures are mostly inclined 80–90° to the a-b planes of the host clasts, whereas the neofractures are usually inclined at 0–80° to these planes. The occurrence of neofractured clasts within the analysed gravels results from tectonic activity post-dating gravel deposition.
W czwartorzędowych żwirach rzecznych odsłoniętych w pobliżu regionalnego nasunięcia w polskich Karpatach Zachodnich powszechnie występują spękane klasty skał fliszowych. W analizowanym materiale klasty skał drobnoziarnistych są częściej spękane, niż klasty skał gruboziarnistych. Obserwuje się też dodatnią korelację pomiędzy liczbą spękanych klastów a ich wielkością. Wśród spękań występują spękania odziedziczone po spękaniach ciosowych tnących skały macierzyste oraz neospękania, które powstały in situ w żwirach. Te dwie grupy spękań cechuje różna orientacja w stosunku do współrzędnych geograficznych oraz do powierzchni a-b klastów, tj. płaszczyzny zawierającej oś o maksymalnym (a) i pośrednim (b) wymiarze. Spękania odziedziczone są zorientowane chaotycznie w stosunku do współrzędnych geograficznych, podczas gdy orientacja neospękań jest uporządkowana. Spękania odziedziczone są zorientowane niemal pionowo (80-90°) względem powierzchni a-b klastów macierzystych, natomiast neospękania są zorientowane pod katami 0-80° do tych powierzchni. Pochodzenie neospękań jest wynikiem aktywności tektonicznej, która miała miejsce po osadzeniu analizowanych żwirów.

The paper presents the results of new studies of Quaternary deposits filling the Kleszczów Graben in the Szczerców outcrop, Bełchatów Lignite Opencast Mine. Sedimentary successions were profiled in the fieldwork. Moreover, the borehole data were studied. Laboratory studies included: grain size analyses, analyses of shape and morphology of quartz grain (morphoscopy), analyses of anisotropy of magnetic susceptibility (AMS), palynological, malacological and ostracodological studies, as well as geochronometric (C14) and geochemical (δ18O/δ16O) measurements. The studies were carried out in 2009–2013 and resulted in discovering of some sedimentary formations as well as arranging geological cross-sections and synthetic lithostratigraphic profile. The following sedimantary formations have been distinguished: Folwark, Kuców, Czyżów, Ławki, Rogowiec, Aleksandrów, Piaski and Widawka, arranged into two structural units: the lower one – deformed, and the upper one – undeformed.

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.

Opis:
According to the current state of research five sand-gravel accumulation levels of Quaternary age are visible in the morphology of the western part of the Holy Cross Mountains, within the Wierna Rzeka, Hutka and Bobrza river valley systems and the lower stretches of the Biała Nida and Czarna Nida river valleys. Two upper levels (V and IV) correspond to valleys formed during the Odranian Glaciation-Saalian, MIS6 and its reccesional phases under the influence of proglacial and extraglacial waters beyond the extent (to the east) of the maximal ice-sheet limit of this glaciation, reaching to the present-day Leśnica-Gnieździska-Łopuszno line. Two lower levels (III and II) are terraces that were typically formed during the climatic conditions thatprevailed during Vistulian stadials. Sands and gravels of the three upper levels (V−III) contain numerous debris flow deposits and cryoturbation structures documenting periglacial conditions during their accumulation. The lowermost level (I) is a typical Holocene floodplain.

Opis:
Stable isotope analyses on carbonates from lake evaporites collected from the non-marine western Qaidam basin yield a positive excursion from Pliocene to Quaternary times. At Dafeng Shan, the Quaternary sequences are composed of alternating layers of celestine/dolomite and aragonite/calcite/barite with distinct isotopic compositions. The sequence described at Dafeng Shan formed in a low energy, hypersaline lacustrine environment as indicated by the microstructures and evaporitic minerals as well as by the absence of lithoclasts. The peloids, ooids and oncoids described are related to microbialactivities in saline lake. The oxygen isotopic composition of the carbonates vary between +34.4 and +39.8‰ (SMOW), representing the heaviest values measured until now. The δ18 O and the δ34 S isotopic composition of the celestine range between 20.1 to 22.3‰ (SMOW) and +19 to +22‰ (CDT) respectively, suggesting sulfur recycling via sulfide oxidation. The carbon isotopic compositions of the carbonates show a large negative excursion of up to -30‰. The microstructures, mineralogy and isotopic compositions as well as the geological context suggest oxidation of methane from a deep source.

Opis:
Amphipatic compounds exhibit an antimicrobial action both on bacteria and fungi. It is caused by a penetrative property of hydrophobic carbon chain of the compuound into a plasma membrane as well as by additional interaction of membrane elements and a hydrophilic amphipathic compound head. Bactericidal and fungicidal activity of this compound strongly depends on chemical environmental factors. In general, microorganisms are not as sensitive in a full medium as in a minimal one and the level of sensitivity rises when the amphipatic compounds are presend in destilled water. Similarly, the sensitivity is stronger in fluid than on solid medium. Our researches revealed however that some aminoacids, although they are complex organic compounds, increase the microbial sensitivity to some tested compound. This efect depends on a microorganism and on a kind of compound. The highest hipersensitivity has been observed against yeast-like fungi when arginine was a cooperating aminoacid. The effect concerns Trichosporon but not E.coli, not occurs in relation to SDS, quaternary ammonium salt IA, and bisammonium salts. Certainly the effect exhibit QAS, which have simple composition of hydrophilic „head” consisting only of methyl group, attaching to alkilic chain possessing keton group, build of 14 or 16 carbon atoms.
Jednoamoniowa sól czwatorzędowa z 14 atomami węgla w łańcuchu węglowym wykazuje silniejsze działanie letalne wobec Trichosporon cutaneum na podłożu pełnym oraz podłożu opartym na hydrolizacie kazeiny niż na podłożu minimalnym. Taki efekt uzyskuje się również z solą o 16 węglach w łańcuchu. W przypadku dwuamoniowych związków tego typu, SDS oraz soli amoniowej z aromatycznym pierścieniem, wzrostu wrażliwości w obecności aminokwasów nie zaobserwowano. Poza T. cutaneum większa wrażliwość w obecności aminokwasów wystąpiła również w przypadku drożdży, lecz nie w przypadku testowanych bakterii Pseudomonas sp. i Escherichia coli. Największą aktywność grzybobójczą soli amoniowych uzyskano dla argininy. Efekt ten jest znacznie silniejszy w podłożu płynnym niż stałym.

Opis:
The Pleistocene to Holocene succession in the Gaza Strip, Palestine, consists of an alternation of calcareous sandstones and reddish fine-grained deposits (palaeosols). The palaeosols can be subdivided into two main groups based on the sand-sized versus clay- to silt-sized grains: (1) the sandy hamra palaeosols, and (2) the loess and loess-derived palaeosols. The hamra palaeosols can, in turn, also be subdivided into two main types according to their colour and grain size: (1) light brown loamy to sandy hamra palaeosols, and (2) dark brown sandy clay hamra palaeosols. The hamra palaeosols are polygenetic and originated in humid environments. Their red colour results from ferric oxides coating the sand grains, but also by illuviation. The various pedogenitic units and their gradual transition to loess palaeosols are due to different phases of dust accretion. Both groups of palaeosols developed during the last glacial. They are considered to represent different climate environments: hamra palaeosols represent humid climates, whereas the loess and loess-derived palaeosols represent dry and semi-dry climates.

Opis:
Spełniając wieloletnie postulaty badaczy czwartorzędu, Komitet Wykonawczy Międzynarodowej Unii Nauk Geologicznych (IUGS) ratyfikował propozycję Międzynarodowej Komisji Stratygrafii obniżenia dolnej granicy czwartorzędu do dolnej granicy piętra gelas (2,588 Ma), a dolna granica plejstocenu została obniżona do tego samego poziomu. Dotychczasowa dolna granica czwartorzędu i plejstocenu, wyznaczona przez stratotyp Vrica w południowych Włoszech i datowana astronomicznie na 1,806 Ma, została utrzymana, ale jako dolna granica piętra kalabr, czyli piętra drugiego od dołu w zrekonstruowanym oddziale plejstocen. Nowa dolna granica czwartorzędu odzwierciedla moment kluczowych zmian klimatu Ziemi w pobliżu granicy epok paleomagnetycznych Gauss i Matuyama. Punkt krytyczny tych zmian został przekroczony około 2,7 Ma, kiedy nastąpiła drastyczna przebudowa cyrkulacji oceanicznej, spowodowana ostatecznym zamknięciem przesmyku panamskiego oraz zmniejszeniem zasolenia wód powierzchniowych Oceanu Arktycznego. Sprzyjało to utworzeniu stałej pokrywy lodowej w Arktyce, a wywołany tym wzrost albedo doprowadził do dramatycznej i jak dotąd nieodwracalnej ewolucji Ziemi, zdominowanej od tego czasu przez epokę lodową, z wielokrotnymi transgresjami lądolodów na kontynentach półkuli północnej.
Many years’ consequent postulates of Quaternary scientists resulted in a decision of the Executive Committee of the International Union of Geological Sciences (IUGS) to ratify a proposal of the International Commission on Stratigraphy to lower the base of the Quaternary to the lower boundary of the Gelasian stage. Simultaneously, the lower boundary of the Pleistocene has been moved to the same position. The previous lower chronostratigraphic boundary of the Quaternary, represented by the Vrica stratotype in southern Italy, has been hardly recognizable outside the Mediterranean Region and neither biostratigraphic indices nor traces of extreme geological events could be found in this very place. On the other hand, an establishment of the Vrica site as the stratotype for the Neogene/Quaternary boundary (equivalent to the Pliocene/Pleistocene boundary) was a driving force to create the Gelasian as a new and uppermost stage of the Pliocene. The Gelasian filled a hiatus between the upper boundary of the Piacenzian stage at Castell Arquato and the boundary of the so-called Plio-Pleistocene at Vrica. The lower boundary of the Gelasian was defined at 2.588 Ma, close to a boundary of the palaeomagnetic epochs Gauss and Matuyama. The new lower boundary of the Quaternary reflects a principal transformation of the climate on the earth. A critical change occurred at about 2.7 Ma, when a severe reconstruction of the thermohaline circulation took place, caused by a final closure of the Panama Straits and inflow of freshwater to the Arctic Ocean. The latter favoured development of constant ice covers in the Arctic, a higher albedo of which resulted in initiation of the ice ages in the northern hemisphere.

Opis:
In the Odra and Osobłoga River valleys in the vicinity of the town of Krapkowice, a system of morphological levels is present which is exceptionally extensive compared to other such systems in southern Poland. The extent, origins and chronology of these levels have been the subject of many controversies. In the light of current research, the terraces, which are situated on average 14.5-13, 12-10, 8-6, 6-4 and 3-1 metres above the river level, were formed in the post-Wartanian interval. The main factor driving their development was erosion, which compensated for the effects of large-scale aggradation that had occurred during the anaglacial phase of the Odranian Glaciation (MIS 8) dated to 261 ±15 ka. The impact of climatic conditions on the trends towards fluvial erosion or accumulation was only of secondary importance. According to OSL dating, successive phases of vertical stabilisation of the valley floor occurred ~118.8 ±8.3, 87.7 ±5.7 and 42.0 ±2.0 ka. In the meantime, erosion intensified, which resulted in the formation of lower terrace levels. During the climatic minimum of the Upper Plenivistulian (21.5 ±1.5 ka), under conditions of the delivery of sheet-wash-generated sediment, the aggradation of distal reaches of the Odra River valley was locally marked. During the Late Vistulian and Holocene, erosive tendencies continued, which were reflected by the fact that the surfaces of subsequent inset alluvial fills were situated ever lower. In the light of dating results, it can be concluded that during the colder periods correlated with the Rederstall Stadial (MIS 5b) and with the Hasselo Stadial (MIS 3), a braided river was present in the river valleys examined, which was most probably accompanied by permafrost. During the Eemian Interglacial (MIS 5e), during the Late Vistulian Interstadials and in the Holocene, it was a meandering river.

Opis:
Neotectonic (Pliocene-Quaternary) elevations and depressions detected on maps of subenvelope surfaces of the topography of the Outer West Carpathians of Poland are, to a certain extent, portrayed on the map showing topography of the Magura floor thrust, particularly in the western segment of the study area. The floor thrust of the Magura Nappe is highly uneven, its position changing from 725 m a.s.l. to more than 7,000 m b.s.l. The most prominent depression is located in the medial (S of Dunajec and Poprad confluence) segment of the Polish Outer Carpathians (2-7 km b.s.l.), and its axis trends NW-SE from the eastern margin of the Mszana Dolna tectonic window to the Poprad River valley. Another, much more shallower, Jordanów depression (2 km b.s.l.) is to be found NW of the Mszana Dolna tectonic window, shortly north of the Skawa River valley. Elevated structures, in turn, include the Mszana Dolna tectonic window, Sól-Skomielna (on the west), and Limanowa (on the east) elevations of subparallel orientation. Still farther to the east, a longitudinal elevation extending between the Klęczany-Pisarzowa and Świątkowa tectonic windows is to be seen some 10-15 km south of the Magura frontal thrust. South of this area, the Magura floor thrust slopes steeply down to more than 4 km b.s.l. A comparison between the pattern of elevated and subsided structures of the Magura floor thrust and subenvelope surfaces of different orders shows that in the western part of the Polish Outer Carpathians the highest-elevated neotectonic structures (in the southern portion of that area) coincide with depressions of the Magura thrust, whereas farther north a reverse pattern becomes dominant: neotectonic elevations coincide either with the Magura frontal thrust or with elevations of its surface. This is particularly true for an area comprised between 20° and 20°30’E meridians. The origin of such relationships is difficult to explain. We infer that one of possible factors could be Pliocene-Quaternary reactivation of faults cutting the Magura floor thrust, and particularly that one, which appears to separate the western-medial segment of the Outer Carpathians from their more eastern portion.
