Opis:
The article presents results of research of three sections (Kuców 9, 10 and 16). Two of them record fluvial and lacustrine interglacial sediments and the third, cold-stage glaciolacustrine sediments. They were formed inside the Miocene – Pliocene syncline depressions in a central part of the southern horst within the Kleszczów Graben. Fluvial and lacustrine deposits of the Middle Pleistocene Interglacial (Mazovian or Ferdynandovian in the Czyżów Formation) are described from the Kuców 9 and 10 sections. Their sediments are located in marginal parts of a buried river valley and within an oxbow palaeolake, then covered by glaciofluvial deposits of the Ławki (Early Saalian) and Rogowiec (Late Saalian) Formations. The Kuców 16 section comprises ice-dam sandy lithofacies (Kuców Formation, Elsterian) of a marginal part in a proglacial lake. Two pollen diagrams of K65/15 and Kuców 9 sections represent the Mazovian (Holsteinian) succession, although in the Kuców 9 section some features are typical for the Ferdinandovian succession.

Opis:
The paper is focused on the palaeographic development of the western part of the Holy Cross Mountains, Poland, during the maximum extent of the Sanian 2 (MIS 12) ice sheet and its retreat. The studies were based on archival cartographic data, coupled with new lithological and petrographic analyses of limni- and fluvioglacial sands, i.e., grain-size composition, quartz grain morphology and heavy mineral analysis, as well as analysis of the erratic material of tills. The results confirm the regional variability of the erratic material in the Sanian 2 tills and point to the long-term development of fluvioglacial sands cover documenting cold climate conditions. They also evidence that the western part of the Holy Cross Mountains was the area where two oppositely directed ice sheet lobes (Radoszyce and Sandomierz) advanced during the Sanian 2 Glaciation and that deglaciation of the area took place in two stages. Huge quantities of meltwater released at that time contributed to the intensification of earlier initiated karst phenomena, as well as filling of the existing caves by fluvioglacial sands.

Opis:
This paper presents the Late Glacial stage of the development of the Białe Ługi peatland in the southern Holy Cross Mountains, based on a comprehensive palaeoenvironmental data. A complex analysis of palynology, Cladocera, sedimentology, geochemistry and 14C dating were used. Organic deposition was initiated during the Oldest Dryas. The sedimentary record of the aquatic and terrestrial ecosystems reflects considerable difference between cooler (Oldest, Older and Younger Dryas) and warmer phases (Bølling and Allerød). Periods of intensified interaction between aeolian processes and peatland are related to stages of disappearing vegetation and changes in aquatic invertebrate communities. We therefore suggest that peatlands were created as a result of local lithological-structural, tectonic, hydrogeological and morphological conditions, and the peatland development rate was largely influenced by changing climatic conditions, which determined local vegetation development, intensity of denudation processes and water level changes. The results validate significance of selection and use of several methods, as well as value of biogenic deposits from the Białe Ługi peatland as archives of past climate change in the Małopolska Upland. Relatively stable water conditions and uninterrupted biogenic sedimentation in the Late Glacial that were provided by the geological structure and relief suggest the studied peatland is a leading one in the region.

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:
GPR method is perfectly suited for recognizing of sedimentary facies diversity in shallowly occurring sediments if there is a contrast of electrical properties between and/or within each layer. The article deals with the issue of the correlation between GPR surveys results and sedimentological analyses. As a result of this correlation a conceptual model of depositional systems of studied areas was developed. Studies were performed in two areas located in central Poland, where glacial deposits formed in the Middle Polish (Saalian) Glaciation are present. The study was based on 49 sediment samples and 21 GPR profiles. Analyses of lithofacies as well as granulometric and mineralogical composition of deposits of collected samples were carried out, showing the diversity of glacial deposits in both study sites. During GPR measurements shielded antenna with a frequency of 500 MHz was used which allowed high-resolution mapping of the internal structure of deposits and to identify four characteristic radar facies. Correlation of GPR profiles with point, one-dimensional sedimentological studies allowed the unambiguous interpretation of the GPR image and draw conclusions about the formation environment of individual units. Geophysical and sedimentological data obtained during study provide a new and detailed insight into selected glacial deposits in central Poland.

A nautilid faunule of seven specimens, comprising Eutrephoceras bouchardianum (d’Orbigny, 1840), Cymatoceras deslongchampsianum (d’Orbigny, 1840), and Cymatoceras tourtiae (Schlüter, 1876) is described from a condensed middle Cenomanian interval at Annopol, Poland. C. tourtiae is recorded for the first time in Poland. The studied material consists of reworked phosphatised internal moulds of phragmocones, which may be of early or middle Cenomanian age, given the stratigraphic range of the associated ammonites. The nautilid moulds vary in inferred mode of infilling, and in intensity of abrasion, bioerosion and mineralisation. The sediment entered the phragmocones in two ways: 1) through punctures in the shell, the result of bioerosion or mechanical damage; 2) through siphonal openings by intracameral currents. In contrast to the fossil moulds from the Albian phosphorites of Annopol, which originated via direct precipitation of apatite around and/or inside fossils, the present nautilid moulds seem to have originated through secondary phosphatisation of the initially calcareous moulds. Diversity of taphonomic signatures in nautilid material from the middle Cenomanian interval at Annopol is compatible with the complex, multievent depositional scenario proposed for this level.

Opis:
Retinitis pigmentosa is a genetic disorder that results in nyctalopia and its progression leads to complete loss of vision. The analysis and the study of retinal images are necessary, so as to help ophthalmologist in early detection of the retinitis pigmentosa. In this paper fundus images and Optical Coherence Tomography images are comprehensively analyzed, so as to obtain the various morphological features that characterize the retinitis pigmentosa. Pigment deposits, important trait of RP is investigated. Degree of darkness and entropy are the features used for analysis of PD. The darkness and entropy of the PD is compared with the different regions of the fundus image which is used to detect the pigments in the retinal image. Also the performance of the proposed algorithm is evaluated by using various performance metrics. The performance metrics are calculated for all 120 images of RIPS dataset. The performance metrics such as sensitivity, sensibility, specificity, accuracy, F-score, equal error rate, conformity coefficient, Jaccard’s coefficient, dice coefficient, universal quality index were calculated as 0.72, 0.96, 0.97, 0.62, 0.12, 0.09, 0.59, 0.45 and 0.62, respectively.

Opis:
This article presents the results of studies of strontium and barium content in Triassic (Muschelkalk) carbonate rock samples taken from the area of the Polish part of the Germanic Basin (the area of Opole Silesia). Sr and Ba were determined in the rocks of all formations of the Lower Muschelkalk - Gogolin Beds, Górażdże Beds, Dziewkowice (Terebratula) Beds and Karchowice Beds. Strontium and barium are chemical elements characteristic for aragonite carbonate phase. Aragonite is unstable calcium carbonate phase which is transformed such as high-Mg calcite into low magnesium calcite during diagenesis. So as Sr and Ba indicate the presence of aragonite in the primary carbonate material. Now these elements concentrate in low-Mg calcite crystal structure. The Triassic rocks of Lower Muschelkalk which are mined in different quarries of the Opole Silesia area are mainly built of low-Mg calcite with lower amounts of high-Mg calcite, protodolomite, ordered dolomite and huntite. There are smaller addition of non-carbonate minerals - quartz, chalcedony, muscovite, feldspars and iron minerals. The presence of Sr and Ba now bound in a structure of low-Mg calcite will indicate the occurrence of aragonite in the primary carbonate material. The Triassic rocks from the area of Opole Silesia were studied to determine the rocks enriched in Sr and Ba. Selected rock samples were examined using ICP AES spectrometry, XRF analysis and microprobe measurements. The results of studies show that strontium and barium occur in rocks of all Lower Muschelkalk formations. The lowest contents of these elements were determined in rocks of Gogolin Beds, higher - in rocks of other formations. The results of studies show that Sr and Ba concentrate in low-Mg calcite which dominates in Lower Muschelkalk rocks. Limestone built mainly of low-Mg calcite or “pure” calcite without substitution of other elements, especially Mg, Fe, Si and Al could be applied in lime industry or in other branches of industry, where pure quality raw material, without substitutions is needed.
W artykule przedstawiono wyniki badań zawartości strontu i baru w próbkach skał węglanowych triasu (wapienia muszlowego), pobranych w obszarze polskiej części zbiornika germańskiego (rejon Śląska Opolskiego). Stront i Bar oznaczono w skałach wszystkich formacji dolnego wapienia muszlowego – w warstwach gogolińskich, górażdżańskich, dziewkowickich (terebratulowych) i karchowickich. Stront i bar są charakterystyczne dla aragonitowej fazy węglanowej. Aragonit stanowi niestabilną fazę węglanu wapnia, która, podobnie jak kalcyt wysokomagnezowy ulega przeobrażeniu w niskomagnezowy kalcyt podczas diagenezy. Zatem obecność Sr i Ba wskazuje na występowanie aragonitu w pierwotnym materiale węglanowym. Obecnie pierwiastki te występują w strukturze niskomagnezowego kalcytu. Skały triasowe dolnego wapienia muszlowego, eksploatowane w różnych kamieniołomach obszaru Śląska Opolskiego są zbudowane głównie z niskomagnezowego kalcytu przy mniejszym udziale kalcytu wysokomagnezowego, protodolomitu, dolomitu uporządkowanego i huntytu. W skałach tych występują niewielkie domieszki minerałów niewęglanowych – kwarcu, chalcedonu, muskowitu, skaleni i minerałów żelaza. Obecność Sr i Ba, związanych w strukturze niskomagnezowego kalcytu będzie wskazywać na występowanie aragonitu w pierwotnym materiale węglanowym. Skały triasowe z obszaru Śląska Opolskiego analizowano w celu określenia, które wapienie są wzbogacone w Sr i Ba. Wybrane próbki skał poddano następującym analizom: spektrometrii ICP AES, analizie XRF oraz badaniom w mikroobszarach. Wyniki badań wykazały, że stront i bar występują w skałach wszystkich formacji dolnego wapienia muszlowego. Najniższe zawartości tych pierwiastków oznaczono w skałach warstw gogolińskich, wyższe w skałach pozostałych formacji. Wyniki badań wskazują, że Sr i Ba koncentrują się w niskomagnezowym kalcycie, który dominuje w skałach dolnego wapienia muszlowego. Wapienie zbudowane z niskomagnezowego kalcytu lub „czystego” kalcytu bez podstawień innych pierwiastków, głównie Mg, Fe, Si i Al, mogą być stosowane w przemyśle wapienniczym lub innych gałęziach przemysłu, w których wymagany jest surowiec „czysty” jakościowo, bez domieszek.
