Opis:
The Sub-Tatric units was newly mapped for the implementation of the Detailed Geological Map of the Tatra Mountains at the scale of 1 : 10 000 (SmgT). Lithostratigraphic andtectonic field observations between the Bystra Valley and the Strążyska Valley allowed a newinterpretation of the geological structure of the area. The system of sheets has appeared to beeven more complicated than that advocated by Guzik and Kotański (1963). New sheets have been recognized: Grześkówki sheets (Lower and Upper sheets), which were distinguished from the former Grześkówki sheet (sensu Guzik & Kotański, 1963), and the Kazalnica sheet and Żywczańskie sheet, which were distinguished from the Samkowa Czuba sheet. Both Grześkówki sheets and Kazalnica sheet are composed of Carnian and Norian clastics or marly dolomites, Rhaetian limestones and Hettangian clayey-silty shales. The Lower Grzeoekówki and Kazalnica sheets lie in the inverted position and Żywczańskie sheet is composed of an isolated package of Lower Jurassic spotted marls and limestones lying in the normal position contrary to the inverted beds of the Samkowa Czuba sheet. The Spadowiec sheet has a wider spatial extent than it was postulated earlier. The Jastrzębia Turnia sheet probably does not exist in area between the valleys of Białego and Bystra.

The provenance and diagenesis of the siliciclastic and hemipelagic sediments of three lithostratigraphic units: Lhoty Formation, Barnasiówka Radiolarian Shale Formation (BRSF) and Variegated Shales from Lancko- rona area, Polish Outer Carpathians, was approached by means of petrological and geochemical analysis of the representative samples. Data show that studied succession was mainly derived from two sources: 1. a dominant terrigenous fine-grained components have affinity with average upper continental crust (basing on mineral detritus, K2O/Rb ratio and Y/Ni vs. Cr/V ratios) and 2. biogenic siliceous material and macerals. Composition varies up section and accounts for changes in the detrital supply due to eustatic sea-level changes. Organic petrology shows presence of organic detritus within the Lhoty Fm and dominance of marine-derived macerals in the BRSF. Chemical and petrological features imply a progressive deepening of the basin. The studied succession was diagenetically altered (e.g. coalification of bituminite, illitisation of smectite and pyritisation).

Opis:
The turbiditic to hemipelagic, fine-grained deposits of the Hradiště Formation (Hauterivian, 132 Ma) to the Lhoty Formation (Albian–Cenomanian, 99 Ma) in the western part of the Silesian Nappe (Polish Outer Car- pathians) were studied mineralogically and geochemically to determine if the main factors controlling the chemistry of the sedimentary material can be attributed to provenance, or to post-depositional processes. A high degree of weathering of the source rocks is indicated by the chemical index of alteration (CIA) that varies from 75.98 to 89.86, and Th/U ratios (~4 with outliers at 1.85 and >6). The cooccurrence of rounded and unabraded grains of zircon and rutile, the enrichment in Zr and Hf, as well as the high Zr/Sc ratios suggest that the Hradiště and Veřovice Formations contain recycled material. Plots of La/Th versus Hf and Th against Sc show that samples occur in the field of felsic and mixed felsic/basic sources. On a ternary La–Th–Sc diagram, all of the sediments studied are referable to the continental island-arc field. The European Plate, as an alimentary area, has a mosaic structure consisting of Cadomian and Variscan elements. The Proto-Silesian Ridge was detached from the continent, because of rifting. Therefore, it could have corresponded to a continental island arc. The concentrations of Fe and trace metals (e.g., Mo, Au, Cu) in the Veřovice Formation and silica and potassium additions to the Veřovice and Lhoty Formations, as well as the fractionation of REE, and Nb, Ta, Zr, Hf, and Y can be explained by the action of basinal brines. The fluids were of hydrothermal origin and/or were released, owing to the dewatering of clay minerals. Diagenetic processes could have exerted a greater influence on sedimentary rock chemistry than the provenance and sedimentary processes. A distinction between primary, terrigenous elements and those changed diagenetically is necessary for the reliable determination of provenance.

Opis:
The Outer Carpathians are known for a few sections, where transitions from the Upper Cretaceous to the Palaeogene, including the K-Pg boundary interval, were described. One of them, the Bąkowiec section in the Skole Nappe, was examined with reference to the record of biostratigraphy and palaeoenvironmental changes, mainly based on the analysis of calcareous nannofossil assemblages. This study shows no evidence for the K-Pg boundary; however, the presence of the nannofossil species Micula prinsii, marking the topmost Maastrichtian UC20dTP Zone, was noted. The appearance of this low-latitude taxon and relevant changes in the composition of nannofossil assemblages indicate an influx of Tethyan warm water into the northern Carpathian basins during the latest Maastrichtian, shortly before the K-Pg boundary event. Therefore, the authors infer that the upper part of the Bąkowiec section recorded the latest Maastrichtian warming of climate, probably triggered by Deccan volcanic activity.

Opis:
Interesting objects – the rocky forms and waterfall thresholds, built of Yamna Sandstone occur in the vicinity of Skole town. Beside the esthetic positive aspects related the morphological variety of the rocky forms and occurrence of the diversified weathering structures, the objects have a substantial cognitive value encompassing the lithology and sedimentological processes of the thick-bedded turbidites. The sandstone rocky forms usually occur in the groups distributed on slopes and forming so-called rocky towns. Their number and distribution allow observation of the changing structural and textural features both lateral and vertical within the 100-m thick composed profiles. The excellent degree of rocks outcropping, variety of structural and textural features and spectrum of possible observations indicates the high geotouristic potential of the investigated objects.
W okolicy miasta Skole, w obrębie wychodni piaskowca jamneńskiego występują interesujące obiekty geoturystyczne, do których należą piaskowcowe formy skałkowe i progi wodospadowe. Oprócz wysokich walorów estetycznych, związanych z urozmaiceniem morfologicznym terenu i różnorodnością poszczególnych skałek oraz struktur wietrzeniowych, obiekty te mają istotną wartość poznawczą w zakresie wykształcenia litologicznego oraz procesów sedymentacyjnych gruboławicowych turbidytów. Skałki piaskowcowe zwykle występują w grupach rozmieszczonych na stokach, tworząc miasta skalne. Taka liczebność oraz położenie daje możliwości obserwacji zmienności cech tekstualnych i strukturalnych, zarówno lateralnie, jak i wertykalnie, w obrębie ponad stumetrowych złożonych profili. Znakomity stopień odsłonięcia oraz różnorodność form strukturalnych i tekstualnych oraz spektrum możliwych obserwacji wskazuje na wysoki potencjał geoturystyczny.

The "Las Gościbia" includes the northern slopes of Babica Mt. (Beskid Makowski) in the catchment area of a mountain stream called Gościbia. It is located within the Magura Nappe in the Siary Zone (Outer Carpathians). In the deeply cut valleys there is exposed continuously profile of the flysch deposits of Eocene-Oligocene age (Pasierbiec Sandstone, Zembrzyce Shale, Wątkowa Sandstone). The special value of the "Las Gościbia" are cascades and waterfalls, which are numerous here in stream valleys. Their abundance, the heterogeneous nature and high aesthetic values determined a high educational and geotourist potential.

Opis:
To optimize exploration for new hydrocarbon accumulations in the Polish Outer Carpathians, it is necessary to concentrate attention on identification of hydrocarbon accumulations of the “shale-gas” type. Results of recently completed analysis suggested new such possible targets in the Magura Basin, preserved in the Outer Carpathian Magura Nappe. Analysis of the preliminary results of paleoenvironmental and geochemical studies of these shales is the subject of this paper. Micropaleontological and geochemical study was conducted on the 300 m thick Świątkowa Member, the uppermost part of the Ropianka Formation located in the external, northernmost Siary Zone. This member is composed of thin- and medium-bedded sandstones interbedded by green, brown, black and dark-gray shales. Poor and changeable oxygenation is reflected in the composition of foraminiferal assemblages. A negative correlation between the TOC content and numbers and diversity of foraminifera is observed. The paleogeographic position and paleoenvironment assessment indicates that the Siary Zone fulfills certain conditions for organic productivity and preservation during the deposition of the Ropianka Formation.

Opis:
In the lithostratigraphic section of a sedimentary sequence of the Silesian Nappe in the area of Rożnów Lake, the strata that occur above the Ciężkowice sandstone and below the Globigerina marls are represented by a relatively thin unit informally named the Hieroglyphic beds and a succeeding thick complex of so-called Green shales. The Hieroglyphic beds, deposited over a short time interval during the Lutetian time (Reticulophragmium amplectens zone), are followed by the Green shales that were deposited from the Lutetian to the Priabonian (Reticulophrgamium amplectens, Ammodisus latus, Reticulophragmium rotundidorstum zones). This work describes the foraminiferal assemblages, on the basis of which, the age of the Green shales was established that in the area of Rożnów Lake. Deposition of the Green shale unit started in the Lutetian, while in other regions of the Silesian Basin it is documented from the Priabonian. The upper boundary of the Green shales is isochronous and defined by the base of the calcareous horizon of a specific type of marls known as the Globigerina marls.

Opis:
The sedimentation of Hieroglyphic beds of the Silesian Nappe took place between the Lower and Middle Eocene and Upper Eocene within the Carpathian Silesian Basin. These beds are represented by thin-bedded flysch containing – at various stratigraphic positions – sandstone-less complexes with variegated shales and bentonite laminae developed in conditions of calm sedimentation with a limited supply of material from the land. The profiles of Hieroglyphic beds of the Silesian Nappe are diversely developed. Their variability and borderline sequences, transitory into overlying and underlying divisions, are presented. In the Ypressian, during the sedimentation of Hieroglyphic beds, foraminiferal associations with numerous small sized Trochammina developed, which formed in the Silesian Basin after the PETM crisis. Since the Lutetian, in slightly more favourable conditions, more differentiated associations have occurred, with Reticulophragmium amplectens (Grzybowski), Ammodiscus (Dolgenia) latus (Grzybowski), and Reticulophragmium gerochi Neagu et al., which preferred cool waters, being index fossils for stratigraphy. Hieroglyphic beds developed during an interval of the gradually cooling climate. The gradual decrease in temperature stimulated the transfer of species: in the Eocene associations of Hieroglyphic beds a number of thermophilous forms, whose optimum of development came in the Upper Cretaceous-Paleocene, disappeared whereas new species appeared which prefer cold waters commonly occurring in boreal basins. The deep restructuring of foraminiferal assemblages took place in the Priabonian, when massive numbers of calcareous benthonic and planktonic forms occurred.

Opis:
The thin- and medium-bedded, turbiditic deposits that are exposed in the Bystrica Zone of the Magura Nappe in the Slovak Orava region are the subject of this study. On the basis of lithological features as well as age and stratigraphic position, they are assigned to the Ropianka Formation. The very well exposed rocks of this formation, recognized in the Biela Farma profile in the Slovak part of the northwestern Orava region, are compared with analogous deposits in the Polish Orava and the Beskid Wysoki Mountains. Lithological and biostratigraphical documentation of the Ropianka Formation is presented. This documentation allowed the determination of the age of the rocks studied. Abundant and taxonomically diverse foraminiferal assemblages of agglutinated, benthonic and occasional planktonic forms indicate a Middle Paleocene age for the upper part of the Ropianka Fm. A new stratigraphic position for the Szczawina Sandstone, considered to be a member of the Ropianka Fm, is proposed. The lithostratigraphy of the Ropianka Fm in the Magura Nappe in Poland, Slovakia and the Czech Republic requires further investigation, including the establishment of new type and reference sections. The large outcrop at Biela Farma should be taken into consideration as a potential reference section. Studies of the new sections will lead to a new monographic elaboration of the Ropianka Fm in Poland, Slovakia and the Czech Republic.

Opis:
A palynological study of uppermost Maastrichtian to Lower Paleocene depos i ts from a stratigraphic section of the Vrancea Nappe (Eastern Carpathians), reveals the presence of diverse and well-preserved dinoflagellate cyst assemblages. The biostratigraphic interpretation of these dinocyst assemblages suggests that (1) the Cretaceous-Paleogene boundary lies within a ~8 m thick sedimentary interval, between the Lepşa Formation (uppermost Maastrichtian) and Putna-Piatra Uscată Formation (Lower Danian), based on the Last Appearance Datum of latest Maastrichtian markers such as Pterodinium cretaceum and Palynodinium cf. grallator and on the First Appearance Datum of Danian markers such as Senoniasphaera inornata, Xenicodinium lubricum, Tectatodinium rugulatum and Eisenackia circumtabulata, and (2) a discontinuity between the two formations. The palynofacies analysis from this geological section indicates an abundance of continental organic matter (mainly opaque phytoclasts), deposited in a distal setting of the sedimentary basin. The occurtences in the palynological assemblage of some oceanic dinocyst taxa such as Impagidinium and Pterodinium suggest the same depositional environment for the geological formations analysed.

Opis:
A study of the second-order folds in the eastern part of the Silesian Nappe allows one to distinguish two groups of structures: longitudinal ones and those orientated obliquely to the strike of the first-order fold axes. Analysis of orientation of the second-order fold axes has made it possible to reconstruct the orientation of s1 stress axes and compression trajectories for each group of folds individually. The results of such a reconstruction imply that the two groups of folds must have been developing independently one from another. Longitudinal folds were formed together with the first-order folds, under the influence of clockwise rotating compression caused by the Early Miocene plate collision, whereas development of the oblique folds was influenced by counterclockwise rotating compression, what seems to be connected with the final push of the Carpathians in Sarmatian times.

The Gorce Mountains are a picturesque range in the Polish sector of the Outer Carpathians. They are built with turbiditic deposits, representing sedimentary successions of the Krynica and Bystrica Subunits of the Magura Nappe, Late Cretaceous- Paleogene in age. In the Gorce Mts. the majority of lithostratigraphic divisions representing discussed subunits are very well exposed in numerous outcrops. The deposits of the Magura Nappe are folded, locally thrust, and cut by the strike-slip and oblique fault system. This nappe in the Gorce Mts. covers tectonically units of the Foremagura Group of Nappes, which crop out in two tectonic windows. From Rabka-Zdrój and Szczawa mineral waters are well known. Morphology of the Gorces Mts. is varied. A lot of rock tors occur there, as well as landslides, often extensive. Good localizations, varied geology, great land relief and rich live nature, as well as the highlander culture and monuments make the Gorce Mts. an area of high geotouristic potential.
Gorce są malowniczym pasmem w polskiej części Zachodnich Karpat Zewnętrznych. Są one zbudowane z turbidytowych, późnokredowo-paleogeńskich utworów reprezentujących osadowe sukcesje krynickiej i bystrzyckiej podjednostki płaszczowiny magurskiej. W Gorcach większość wydzieleń litostratygraficznych reprezentujących wspomniane podjednostki jest bardzo dobrze eksponowana w licznych odsłonięciach. Utwory płaszczowiny magurskiej są sfałdowane, lokalnie złuskowane i pocięte systemem poprzecznych i ukośnych uskoków. Płaszczowina magurska w Gorcach przykrywa tektonicznie jednostki przedmagurskiej grupy płaszczowin, które odsłaniają się w dwu tektonicznych oknach. W Rabce-Zdroju i w Szczawie wykorzystywane są wody mineralne. Rzeźba Gorców jest zróżnicowana. Występują tu liczne skałki oraz osuwiska, często rozległe. Dogodna lokalizacja, interesująca budowa geologiczna, wspaniała rzeźba tego pasma, bogata fauna i fora oraz dziedzictwo kulturalne miejscowej ludności wpływają na duży potencjał geoturystyczny Gorców.
