Opis:
A section over 20 m thick of the basal Middle Miocene succession exposed at Lipowiec (Roztocze, SE Poland) was studied for palynology. Thirteen samples were collected from quartz and glauconitic-quartz sands and thin clay layers. Sand samples were barren but clay samples yielded dinoflagellate cysts. Their assemblages consist of reworked Paleogene specimens dominated by the Homotryblium floripes complex (H. floripes and morphologically similar H. plectilum and H. vallum). The presence of reworked Paleogene specimens indicates intense erosion of marine Paleogene strata during initial stages of the Middle Miocene transgression at Roztocze. Analysis of stratigraphical ranges of reworked dinoflagellate cysts and comparison with their occurrences in known epicontinental Paleogene sites of SE Poland suggest an Upper Eocene age of the washed-out strata. The taxonomic composition of the assemblages described suggests that the Upper Eocene deposits accumulated in a near-shore, lagoonal embayment characterized presumably by oligotrophic waters of slightly increased salinity. A high proportion of the Homotryblium floripes complex is also characteristic of reworked assemblages found in younger Miocene strata of neighbouring exposures in Roztocze, which indicates widespread Eocene lagoonal environments in this part of Roztocze. Coeval Eocene strata from the eastern part of Roztocze and from the Carpathian Foredeep show different taxonomic compositions suggesting varied sedimentary settings during Eocene transgression in this region. These differences reflect variable amounts of freshwater influence resulting in a range of environments that ranged from oligotrophic to brackish.

Opis:
The TL and OSL ages obtained from two ancient kilns and gothic to baroque bricks in the SE of Poland, were compared to their presumed historical ages and discussed. The luminescence ages of ancient kilns were also matched with the results of archaeomagnetic dating. The OSL and archaeomagnetic data indicates that the ancient kilns were last used not later than ca. 280 AD. This age corresponds well to the lower limit of the postulated age of fragments of Roman type storage vessels found in the filling of kilns. The OSL data used alone can point even to the end of the phase B2 of Roman influence in Poland. The TL ages obtained from the kilns (5297 ± 256 BC, 7092 ± 423 BC) are significantly older. These bottom parts of kilns, from which samples were taken, most probably were heated to a relatively low temperature, insufficient to reset the TL signal. Most of TL ages obtained from gothic to baroque bricks do not correlate with their historical ages. Unknown and most probably varied brick moisture contents in sampled ground floor walls and cellars does not allow to precisely date these bricks using the TL signal.

This paper contains palynological and stratigraphical characteristics of the selected Cambrian sections encountered in the basement of the north-eastern part of the Carpathian Foredeep and the Outer Carpathian margin in south-eastern Poland and western Ukraine, as well as verification of the stratigraphical position of rocks recognised so far in several sections in western Ukraine. The acritarch assemblages of the Cambrian System Series 2 are dominated by species of the characteristic early Cambrian genus Skiagia. The Cambrian Series 3 beds are documented by the assemblages with numerous specimens of the Adara alea, Cristallinium cambriense, Heliosphaeridium notatum, Eliasum llaniscum, Multiplicisphaeridium martae, and Comasphaeridium longispinosum. Furongian sediments are evidenced by strongly taxonomically diversified assemblages with large quantities of acritarchs, containing genera Timofeevia, Vulcanisphaera, Ninadiacrodium, Pirea, Leiofusa, Lusatia, or Polygonium, as well as taxa characterized by diacrodial symmetry. These assemblages are dominated by such genera, as: Dasydiacrodium or Acanthodiacrodium, and also by specimens with large polar opening of the central body, belonging to acritarchs of the “galeate” group. Within the studied Cambrian sediments, nine acritarch assemblages of differing composition were distinguished. These assemblages were correlated with faunistic zones. Ages younger than Palaeozoic, identified in some of the analysed Ukrainian sections, were determined basing on very well preserved assemblages of spores and pollen.

Opis:
Miocene strata of the Carpathian Foredeep Basin in Poland contain reworked Eocene and Oligocene dinoflagellate cysts, which come from two sources: the Flysch Carpathians and the epicontinental basin. The occurrence of the latter is almost the only trace of the epicontinental Eocene–Oligocene sedimentary cover, which extended across southwestern Poland, and is today nearly completely eroded. The distribution of epicontinental Eocene and Oligocene taxa in the Miocene strata of the northeastern part of the Carpathian Foredeep is uneven, clearly pointing to a limited extent of the host deposits and their variable erosion intensity. Erosion of the Eocene and Oligocene platform cover took place prior the Miocene transgression and took place also during the Badenian; its intensity increased during Late Badenian–Sarmatian tectonic movements, resulting in an increased frequency of reworked specimens in strata postdating the mid-Badenian deposits.

Opis:
The Sołokija Graben is a tectonic structure in Roztocze, the south-eastern Poland, unique by its infill with the Eocene marine strata. The over 40 metres thick sandy succession is the only well-dated palaeontologically trace of Eocene marine transgression at Roztocze being virtually the only remains of the Eocene epicontinental sea in this part of Poland: the surrounding area is devoid of coeval marine strata, which were eroded. This makes the Sołokija Graben succession crucial for the palaeogeography reconstruction of the south-eastern Poland during Eocene as well as the tectonic history of this region. For its precise age determination, the over 30-m-thick succession of loamy sands that fill the Sołokija Graben in a borehole at Leliszka and a 4-m-thick one at Łaszczówka were sampled for dinoflagellate cysts. Samples from Łaszczówka are barren, whereas the ones from Leliszka contain rich and taxonomically diverse assemblages. Their biostratigraphical interpretation confirms previous results suggesting the Bartonian age of the most of the Sołokija Graben succession; the postulated Priabonian age of its non-calcareous part was documented in its uppermost part only. Palynological record allows reconstruction of sedimentary setting of the Leliszka succession. Basal part of the Bartonian was deposited in a shallow but relatively vast marine basin characterized by normal salinity and high energetic hydrodynamic conditions. Subsequently, marine basin underwent gradual shallowing and temporal cease of sedimentation. During the late Bartonian basin became brackish. A short-lasting early Priabonian marine basin was characterized by shallow marine conditions; it became brackish during its final stage. Comparison with neighbouring Eocene deposits of the epicontinental and Carpathian basins shows that the marine basin at Roztocze was presumably connected with both during Bartonian, and separated from the Carpathian one during early Priabonian. Factors controlling seaways pattern of the Roztocze basin were either eustatics and substratum tectonic movements, the former dominating during Bartonian, and interfingering with uplift of the Meta-Carpathian Swell during early Priabonian.

Opis:
The aim of this paper is to present a characteristic of loess permanent gullies, which form the branched erosion system, with the total length of almost 7.8 km, dissecting an erosion-denudation dry valley. Only 20%of the gully system catchment is cultivated as the result of steep slopes and considerable height differences up to 100 m. 80%of the catchment is covered by fir coniferous forest and Carpathian beech forest, and gully development is the result of intensive forest exploitation. Five types of gullies have been selected on the basis of the runoff directions, which are determined by the following: original relief, runoff concentration from fields, runoff concentration from fallplaces, skidding and course of forest roads used to carry a timber.

Opis:
The litology of the Sandomierz section deposits have been examined, with SEM analysis performed on 4 quartz grain-size classes. All of the Sandomierz deposits contain predominant quartz grains with signs of aeolian transport. This refers both to morainic till and muds underlying the loess section as well to loesses them selves along with soil complexes. A much smaller, although significant contribution comprises redeposited grains with features of a high energy beach environment. Their content in creases up section. During sedimentation of the LMg (younger upper loess) deposits (later part of the Vistulian Glaciation) wind strength was in creasing. This is indicated by the upwards increasing content of coarser fractions within the interval, with simultaneously improved sorting, as well as by the increased contribution of garnets and the greater content of zircon and rutile at the top. The increasing contribution of aeolian quartz grains, the considerable content of grains redeposited from a beach environment and the decreasing amount of post-sedimentary features all suggest increased wind speed. Low variability in the shape of the 1–0.5 mm quartz grains from the LMg horizon indicates short transport and a similar nearby source of material. Alimentary areas for this horizon were composed of young Pleistocene muds and tills. A change in depositional conditions is observed at the LMs/LMg boundary (upper part of the Vistulian Glaciation). During deposition of the LMs (younger middle loess) horizon, wind strength decreased, as shown by the content of heavy minerals and the smaller mean grain-size along with the reduced content of aeolized quartz grains.

Opis:
During the 50-year-long intense petroleum exploration of the Palaeozoic–Mesozoic basement of the Carpathian Foredeep, more than 20 oil and gas accumulations have been discovered. The basic and most important oil-bearing levels in the Mesozoic section are Oxfordian carbonates and Cenomanian sandstones. The Nosówka, Zalesie, Trzebownisko–Krasne, Cetynia, Uszkowce and Lachowice hydrocarbon accumulations and numerous hydrocarbon shows have been found in the Palaeozoic horizons. This paper is focused on evaluation of reservoir properties of the entire Palaeozoic–Mesozoic basement of the Carpathian Foredeep and marginal part of the Outer Carpathians for finding new reservoir horizons. 558 rock samples from 51 wells in the Kraków–Lubaczów area were analysed. The well log results from 20 wells were additionally used for the assessment of petrophysical properties. The results of porosimetry measurements and well logs varied in all discussed Palaeozoic and Meso- zoic basement horizons of the Carpathian Foredeep. The best reservoir properties were estimated within the Jurassic–Lower Cretaceous carbonate complex. Despite great variability, the carbonate rocks display highest average porosity and good permeability values. The variability of reservoir properties is mostly a result of the character of the reservoir-porous-fracture space. Good reservoir properties were also estimated for the Upper Cretaceous carbonate rocks. However, in most of the analysed wells the potential reservoirs were watered. The Palaeozoic complex displays weaker reservoir properties and they mainly refer only to the Devonian–Lower Carboniferous horizon. The Lower Palaeozoic rocks display weak reservoir properties. Their potential is additio- nally lowered by negligible range of occurrence and a small thickness. Generally, the gas- and oil-bearing pro- perties of the analysed zone can be attributed only to the Jurassic–Cretaceous reservoir horizons. The remaining horizons, especially the Upper Palaeozoic complex, are only supplement to the reservoir potential of the area.

Celem pracy było zbadanie różnorodności gatunkowej okrzemek rozwijających się na glebie pod uprawą pszenicy w Pogórskiej Woli koło Tarnowa oraz charakterystyka zbiorowisk okrzemek w oparciu o wybrane właściwości fizykochemiczne gleby. Badania prowadzono w okresie wegetacyjnym (od kwietnia do listopada 2011 r.), próbki powierzchniowej warstwy gleby pobierano w odstępach comiesięcznych. Badania fizykochemiczne wykazały odczyn kwaśny lub lekko kwaśny oraz niskie wartości uwilgotnienia (od około 6% w kwietniu i październiku do 1,93% w czerwcu). Łącznie oznaczono 47 taksonów okrzemek. Największym bogactwem gatunkowym charakteryzowały się rodzaje Luticola, Navicula i Mayamaea. Wyróżniono 8 gatunków dominujących, z których zdecydowaną większość stanowiły gatunki aerofityczne i glebowe. Najliczniejsze populacje tworzyły: Hantzschia amphioxys (Ehrenb.) Grunow, Luticola nivalis (Ehrenb.) D.G. Mann, Pinnularia borealis Ehrenb. var. borealis i Stauroneis borrichii (Petersen) Lund.
Studies were conducted on a farmland located in the Pogórska Wola near Tarnów. The aim of the studies was to examine the species richness of diatoms growing on soil under wheat cropping in the Pogórska Wola and characteristic of diatoms assemblages based on selected physico-chemical parameters of soil. Studies were conducted in vegetation season (from April to November 2011). Samples were collected once a month. Soil reaction in each month was acid or slightly acid. Humidity was low and balanced between 6% in April and October down to 1.93% in June. 47 diatom taxa were recorded in total. The biggest species richness occurred in genus Luticola, Navicula and Mayamea. Eight taxa were considered as dominant from which the most was aerophytic and soli species. The biggest populations were created by: Hantzschia amphioxys (Ehrenb.) Grunow, Luticola nivalis (Ehrenb.) D.G. Mann, Pinnularia borealis Ehrenb. var. borealis and Stauroneis borrichii (Petersen) Lund.

Opis:
A 40-m-thick section of chalk exposed in the Chełm quarry (SE Poland) contains a rather poor assemblage of macrofauna and a well diversified assemblage of foraminifers. The planktonic foraminifer assem- blages characterized by a considerable number of representatives of Globigerinelloides and Heterohelix and the presence of Guembelitria cretacea indicate the lowest part of the Guembelitria cretacea Zone sensu Peryt (1980). Benthic foraminifers point out that the strata of the Chełm quarry section can be attributed to the lower part of the Upper Maastrichtian: i.e., the Gavelinella danica/Brotzenella preacuta Zone of the European Boreal Province or the Anomalinoides pinguis Zone distinguished in Poland (except the Carpathians). The occurrence of ammonites, such as Hoploscaphites constrictus lviviensis Machalski, Hoploscaphites schmidi (Birkelund), and Acanthoscaphites varians blaszkiewiczi Jagt & al. indicates that the Chełm succession belongs to the lower part of the Belemnitella junior Zone, i.e., to the Belemnitella junior–Spyridoceramus tegulatus Zone sensu Schulz & Schmid (1983). The correlation of the Chełm quarry section and the Middle Vistula River Valley section indicates that the equivalent interval of the former section is not exposed in the Middle Vistula River Valley and that it would occur between the Chotcza and Lucimia villages within the lower part of the Belemnitella junior Zone, i.e., within the Belemnitella junior-Spyridoceramus tegulatus Zone distinguished in NW Germany (Schulz & Schmid,1983).
