Opis:
The area of the Dunajec river basin includes several geological units in the Central Carpathian region at the Polish-Slovakian borderland. The paper focuses on the geomorphometric parameters of the drainage system to recognize the influence of the deep seated geological structures on the morphology of the Dunajec river basin (Central Carpathians). The study were enriched with analysis of the geological maps and lineaments extracted from Digital Elevation Model. According to the obtained results, the massive NW-SE trending fault zones play a vital role in the geological architecture of the researched area. The development of the secondary fault structures has been determined by these dislocations and the manifestation of their activity can be observed as deformations of some of the other tectonic structures along the main fault zones, especially at the folds’ axes. Additionally, the geometric and morphometric features of the drainage system have also been influenced by the activity of these deep structures. The tectonic activity represented by the level of morphological rejuvenation, visible in the light of the morphometric parameters of the streams and the drainage basins, varies greatly between the tectonic units. This diversity is caused by both the lithological and structural features of these geological units.

Opis:
The Pieniny Klippen Belt in Poland marks the Central Carpathian-North European plate suture zone. The strictly tectonic present-day confines of the Pieniny Klippen Belt are characterized as (sub)vertical faults and shear zones. A strong reduction in the space of the original sedimentary basins took place. The strike-slip-bounded tectonic blocks, thrust units, toe-thrusts and olistostromes are mixed together, resulting in the present-day mélange character where individual tectonic units are difficult to distinguish. The sedimentary rocks of the Pieniny Klippen Belt were deposited in the paleogeographic realm known as the Alpine Tethys that was divided into two basins separated by the Czorsztyn Ridge. The accretionary prism formed in front of the advancing Alcapa (Central Carpathians) terrane had overridden the Czorsztyn Ridge during the Late Cretaceous-Paleocene. The destruction of the Czorsztyn Ridge supplied huge amounts of coarse-clastic material, including olistoliths, into the Magura Basin during the Late Cretaceous-Paleocene. The rotation of the Alcapa caused the strike-slip motions which led to the deformation of the previously created nappes and development of the flower structure. Two parallel faults delineate the southern and northern limits of the Pieniny Klippen Belt. The stops in Sromowce (Macelowa and Sobczański Gorge area) allow the observation of the southern marginal zone of the Pieniny Klippen Belt, the overturned position of the rotated counterclockwise deformed rock as well as the diapiric uplift of the Pieniny rocks in a transpressional strike-slip regime. The Zawiasy (Krościenko area) stop is located in the northern marginal zone (Hulina Unit) of the Pieniny Klippen Belt along the major dextral strike-slip Dunajec Fault.

Opis:
Several tufa complexes are known in the Slovak Karst which is a typical karst area of a temperate climate. This area is built of Mesozoic carbonates, mainly Triassic in age. The karst systems drain carbonate plateaux and lead water to resurgences located in valleys which are up to 300 m deep. Below the resurgences there are Holocene fossil tufa deposits that exceed 12 m in thickness. The tufas include stromatolite, moss, phytoclastic, oncoidal, and intraclastic facies. Extensive barrages which once dammed the upper reaches of the streams were formed in narrow valleys. They are composed predominantly of moss facies and stromatolites, with subordinate oncoidal and phytoclastic facies. Phytoclastic, oncoidal and intraclastic facies are dominant in dammed segments of streams, and include gastropod shells and charcoal fragments. Some small moss cushions are also developed. Barrages and dammed areas formed in a longitudinal fluvial depositional system. Conversely, below resurgences located on plateau slopes tufas of a perched springline depositional system were formed. These comprise deposits of prograding cascades constructed by moss, phytoclastic and stromatolitic facies. Presently, the tufas analysed are inactive. They stopped growing in the Late Holocene time, after which there was abrupt incision of the streams. This caused downcutting into Holocene tufas, in some places reaching Mesozoic bedrock. At present tufa is being precipitated from streams in all the sites studied.

Opis:
A geological structural study has been conducted along the tectonic contact zone of the Central Carpathian Paleogene Basin (CCPB) and Pieniny Klippen Belt (PKB) in the eastern Podhale and western Spišska Magura areas. It concerned mostly the Central Carpathian Paleogene flysch strata and, to a lesser degree, the Upper Cretaceous rocks of the PKB. Tectonic deformation structures genetically related to the important tectonic boundary in question occur within a c. 1.5–2 km-wide strip of the Paleogene flysch rocks adjacent from the south to the PKB. Two parallel structural domains have been distinguished within this strip: the contact zone proper in the north and the peri-Pieniny monocline in the south. Most of the minor faults documented in the Paleogene flysch bear a record of dextral motion parallel to the contact zone. Some dextral-reverse oblique slip faults of NE-SW and W-E trends have also been recognized. Discrepancies in the orientation and sense of movement on strike-slip faults in the Paleogene flysch rocks and those in marlstones of the “klippen envelope” of the PKB were encountered. They probably reflect differences in the structural history of both the adjacent rock complexes, as the Upper Cretaceous deposits of the PKB must have experienced more deformation events and, in general, were affected by much more intense strain than those of the CCPB. Contractional structures, such as south-vergent reverse faults and recumbent folds which point to ca N-S tectonic shortening, have also been found in the Paleogene rocks. The entirety of the structural features found in the CCPB is characteristic of a transpressional regime. The regionally consistent coexistence of structures resulting from strike-slip movements and tectonic shortening, as well as features pointing directly to a transpressional regime, prove the transpressional dextral nature of the contact between the CCPB and PKB.

Opis:
Tufas in the Podhale Synclinorium (southern Poland) occur as encrustations on moss and plant remains, crusts, porous, clastic and massive tufas. The tufas are almost entirely composed of calcite with small admixture of quartz, illite and chlorite. These deposits indicate the biotic and/or abiotic origin of calcium carbonate. The tufas occur in the vicinity of map-scale and minor fault zones. They precipitate near fissure springs linked with small faults and fault rocks or seepages along them. Exposures with tufas occur along several oblique and lateral zones. The oblique zones are related to Białka and Biały Dunajec faults that have normal components. The lateral zones of tufa occurrences are connected with lateral faults limiting the “zone of beds with gentle dips” and extensional brittle structures within the hinge of the synclinorium. The relationship of the tufa with brittle extensional structures suggests Quaternary tectonic activity of the Podhale Synclinorium that can be explained by continued uplift in the area studied.

Opis:
W artykule przedstawiono wyniki badań nad zgodnością kierunkowości spękań ciosowych, pomierzonych w odsłonięciach skalnych w korytach potoków, z kierunkami przebiegu dolin rzecznych niższego rzędu. Analizy wskazują, że górne odcinki badanych dolin kierunkowo nawiązują do orientacji dominującego systemu spękań ciosowych. Zgodność ta może stanowić świadectwo procesu formowania się dolin rzecznych wzdłuż spękań ciosowych systemu diagonalnego. W przeciwieństwie do górnych odcinków badanych dolin, w ich dolnych odcinkach przebieg osi doliny jest w większości przypadków niezgodny z przebiegiem kierunków spękań ciosowych systemu diagonalnego. W świetle przeprowadzonych badań należy stwierdzić, że kierunek przebiegu analizowanych dolin mógł ulec zmianie w toku ich rozwoju, szczególnie w okresie zlodowaceń tatrzańskich, gdy dolne odcinki dolin były wypełniane materiałem fluwioglacjalnym.
The directions of joints, measured in bedrock outcrops in stream channels, have been compared with the directions of the low-order valleys. The results indicate that upper courses of all studied valleys are consistent with the orientation of dominant joint system. This correlation can be an evidence of valley-forming process along joints of diagonal system. In contrast to the upper courses, lower courses of most of the valleys are inconsistent with diagonal joint system. According to the research results, the valley directions changed in the course of their development, especially during the Tatra glaciations, when lower courses of the valleys were filled with fluvio-glacial material.

Opis:
The High-Tatric succession of the Tatra Mountains represents the Tatricum domain of the Central Western Carpathians, which in the Jurassic was located on the southern margin of the incipient and expanding Vahic Ocean – a branch of Western Tethys. This paper describes the various depositional consequences of extensional tectonic activity as it impacted on sedimentation in the High-Tatric succession of the Tatra Mountains during the Early and Middle Jurassic. Evidence of such impacts on depositional style and facies development are present within the Dudziniec, Smolegowa and Krupianka formations, in all the High-Tatric tectonic units. These impacts also include erosional surfaces and sedimentary gaps separating particular formations, commonly associated with minor angular unconformities. The Lower Jurassic, pre-Bajocian, Dudziniec Formation of the Kominy Tylkowe (autochthonous) Unit is developed in mixed carbonate-clastic facies. The occurrence and proportion of sand-dominated and carbonate-dominated facies, as well as their thickness differences, were controlled by syndepositional tilt-block tectonics, taking place both in depositional and in neighbouring source areas. The Smolegowa and Krupianka formations (Bajocian–Bathonian) occur in all High-Tatric tectonic units, but in the Czerwone Wierchy and Giewont units they are represented mainly by laterally discontinuous bodies of crinoidal limestone of very limited thickness. The preservation of these deposits only in some areas, as well as their thickness reductions, are effects of differentiated subsidence and uplift of isolated blocks taking place in an extensional regime. Moreover, the Krupianka Formation abounds in condensed facies with ferruginous crusts and stromatolites – a feature characteristic of rapidly drowning ocean margins. Deposits of the Dudziniec, Smolegowa and Krupianka formations are also preserved as infills of extensive systems of neptunian dykes penetrating mainly the Triassic substrate, which is yet another classic symptom of synsedimentary extension. The dominant influence of tectonics on sedimentary development ceased with the onset of deposition of the Raptawicka Turnia Formation in the Callovian.

Opis:
The Upper Cenomanian mixed siliciclastic-carbonate succession of the High-Tatric Unit was deposited during the initial stage of basinal closing of the Tatric area, part of the Zliechov (Križna) Basin (Inner Carpathian domain). As a result of tectonic activity taking place at the northern Veporic margin, pulses of siliciclastic input interrupted marine carbonate sedimentation. The siliciclastic material, part of the Zabijak Formation, has been studied along two sections (Pisana Gully and Zdziarski Gully) in the Western Tatra Mountains. Microfacies, petrographic and geochemical analyses reveal a variability of siliciclastic material composed of various types of granitoids and medium- or high-grade metamorphic rocks, with schists and gneisses. Such interpretation is confirmed by the results of elemental chemical analyses, in which immobile trace elements, such as REE, Th, Cr, Co, Zr, and Y were used as indices for sediment provenance. The parent rocks sustained moderate to intense chemical weathering, documented by chemical weathering indices (CIA, PIA, CIW, R). The weathering occurred in a humid climate with relatively high precipitation that caused strong leaching of particles. Chemical indices related to sorting processes suggest that the recycling of the source material was a minor significance. The siliciclastic input displays a waning upward tendency in the sections, which can be associated with diminishing of the source area by gradual inland progradation of a carbonate platform, caused by a global sea level rise during the Late Cenomanian.

Opis:
Calcareous dinocysts and calcitarchs have been investigated for the first time within the Upper Albian limestone and marl succession of the Zabijak Formation from the High-Tatric Unit in the Tatra Mountains (Central Western Carpathians), related to the Oceanic Anoxic Event 1d (OAE 1d). Four groups of morphotaxa of calcareous dinocysts have been distinguished. They totally dominate the assemblages, and belong to the pithonellids. They are represented by Pithonella sphaerica (Kaufmann in Heer) and P. ovalis (Kaufmann in Heer), which dominate, as well as P. trejoi Bonet and P. lamellata Keupp in Keupp and Kienel, which are less abundant. Two other morphotaxa, Colomisphaera gigantea (Borza) and Cadosina oraviensis Borza, occur sporadically in the assemblages. Both forms represent the calcitarch group, which assembled calcispheres of unknown taxonomic affinity. The calcareous dinocyst and calcitarch diversity is low to moderate, compared to the general species richness known from Late Albian assemblages in other Western Tethyan sections. This is interpreted as a result of nutrient input fluctuations due to changes in the circulation pattern of surface and intermediate waters. The changes in the P. sphaerica/P. ovalis ratio along the Upper Albian section are here correlated with short-term (third-order) sea level fluctuations including transgressive and regressive events and a highstand. Pelletization processes might have influenced cyst abundance on the sea floor, especially during periods with oligotrophic surface waters.

Opis:
Biostratigraphic investigations of carbonate strata that sandwich volcanic rocks and studies of the volcanic rocks were made along five composite lithological sections across the Upper Jurassic-Lower Cretaceous carbonate rocks of autochthonous cover of the High-Tatric Unit in the Osobitá peak area of the Western Tatra Mts. A carbonate microbreccia that consists almost exclusively of limestone clasts containing calpionellids occurs immediately below the volcanics. The youngest identified microfossil Calpionella elliptica Cadisch in the individual limestone clasts showed the age of breccia formation to be younger than late Early-early Middle Berriasian. The volcanic rocks are overlain by the Osobitá Limestone Formation, which in the lowermost horizons consists of a few metres thick crinoidal limestone containing the foraminifers Meandrospira favrei (Charollais, Brönnimann & Zaninetti), Sabaudia minuta Hofker and Montsalevia salevensis (Charollais, Brönnimann & Zaninetti) indicating a Late Valanginian-Early Hauterivian age. The biostratigraphical and sedimentological data obtained show that volcanism took place in several phases. Less intense phases of volcanism are recorded as thin tuffitic laminae within the upper parts of the Tithonian-early Mid Berriasian Sobótka Limestone Member and as fragments of volcanic rock in the carbonate breccia. The main phase(s) of volcanism took place during the Late Berriasian-?Early Valanginian.

Opis:
The Biały Dunajec Valley is one of the large, meridionally oriented valleys cutting the Podhale Synclinorium. The tectonic origin of this valley has been suggested since the beginning of the 20th century. A large fault zone with an azimuth of about 20° has been recognized here. This zone extends to the north and cuts the Pieniny Klippen Belt, which is significantly lowered in its eastern side. The southern part of the Biały Dunajec fault zone (SBD) extends probably into the Tatra Massif (into the Mała Łąka Valley area and far to the south into the border of the Koszysta elevation and the Goryczkowa depression). The majority of faults constituting the SBD were formed during the initial phase as strike-slip faults; they were reactivated later as dip-slip faults with a prevailing dip-slip, mainly normal component. As a whole, the SBD is a scissor-like fault: in the northern part, near the Szaflary village, downfaulted is its eastern block, whereas in the southern part - its western block.

Opis:
Planktonic and benthic Foraminifera have been studied from the youngest deposits of the Krosno beds in the inner part of the Silesian Nappe (Outer Carpathians) in the Bieszczady Mountains. The studied part of the Krosno beds consists of Egerian (upper Oligocene–lower Miocene) flysch sediments, deposited within the Outer Carpathian Basin, a part of the Central Paratethys. Two interval zones: Tenuitella munda Zone and Globigeri- nelloides primordius Zone have been distinguished basing on the succession of planktonic Foraminifera. Additionally, Paragloborotalia inaequiconica Interval Subzone has been defined within the first one. Occurrence of calcareous nannoplankton, dinocyst assemblages and isochronous horizons of coccolith limestones (the Jasło Limestone and Zagórz Limestone) enabled correlation of the planktonic foraminiferal zones with chronostrati- graphy. The boundary between the two distinguished zones corresponds to the base of NN1 nannoplankton Zone (defined by the occurrence of Helicosphaera scissura) equivalent to the Oligocene/Miocene boundary. The base of the P. inaequiconica Subzone corresponds to the position of the Zagórz Limestone, refferred to NP 24 Zone (early Egerian). The benthic foraminiferal assemblages are dominated by bathyal, calcareous, hyaline, smooth-walled taxa, indicative of anoxic environment. The benthic assemblages remained relatively stable throughout the late Oligocene and were more diversified during the earliest Miocene, most probably in response to the oxygenation of bottom waters, due to the opening of new connections between the Central Paratethys and the Mediterranean region.
W pracy przedstawiono zespoły otwornic egeru z najmłodszych utworów jednostki śląskiej w bieszczadzkiej części Karpat Zewnętrznych. Otwornice planktoniczne były podstawą do wydzielenia poziomów biostratygraficznych, których granice zostały porównane z danymi opartymi o wapienny nanoplankton (Garecka; w: Haczewski et al., A, B, oddane do druku) i dinocysty (Gedl; w: Haczewski et al., A, oddane do druku), a także odniesieniu ich do pozycji stratygraficznej dwóch chrohoryzontów - wapienia jasielskiego i wapienia z Zagórza. Praca niniejsza jest kontynuacją badań na tym obszarze (Bąk, 1999) i stanowi ich podsumowanie. Płaszczowina śląska jest na obszarze Bieszczadów zbudowana wyłącznie z warstw krośnieńskich (Fig. 1, 2) o miąższości ok. 3,5 km, w tym z ponad 1,3 km miąższości serią zawierającą gruboławicowe, grzbietotwórcze piaskowce otryckie. Ich obecność w warstwach krośnieńskich była podstawą do wyróżnienia w tej części jednostki śląskiej tzw. strefy bieszczadzkiej (lub strefy Otryt - Bitla), której długość wynosi ok. 150 km, a szerokość 15-20 km. W przekroju Bieszczadów strefa ta zbudowana jest z kilku łusek i fałdów, wśród których synklina Dźwiniacza Górnego zawiera bardzo miąższe i najmłodsze serie utworów fliszowych. Dotychczasowe prace stratygraficzne na tym obszarze (Haczewski et al., A, B oddane do druku) wskazywały na oligoceński wiek całej serii warstw krośnieńskich, w tym również warstw najmłodszych. W niniejszej pracy przedstawiono rezultaty opróbowania najmłodszej serii warstw krośnieńskich, tzw. warstw nadotryckich (oddział górny warstw krośnieńskich), które występują powyżej serii z piaskowcami otryckimi. Warstwy nadotryckie (maks. miąższość ok. 1050 m) tworzy seria silnie wapnistych, szarych i ciemnoszarych łupków marglistych, o charakterystycznej grubej (“mydlastej”) oddzielności, przeławicających się z wapnistymi, cienkoławicowymi, laminowanymi mułowcami i piaskowcami. Lokalnie wśród tej serii występują grube ławice piaskowców średnioziarnistych, bezstrukturalnych oraz pojedyncze, czarne serie z wirowcami (o miąższości 1-2 m). W najwyższej części warstw nadotryckich występuje jeden lub kilka soczewkowatych pakietów piaskowców średnioziarnistych, gruboławicowych, z laminacją równoległą, przekątną i konwolutną, o sumarycznej miąższości ok. 30 m. W niższej części warstw nadotryckich wykartowano ponadto 2 ważne dla stratygrafii horyzonty wapieni kokolitowych, tzw. wapień jasielski i wapień z Zagórza. W obrębie badanych utworów zostały one znalezione w obu skrzydłach synkliny Dźwiniacza Górnego. Wapienie te, znane z wielu miejsc w Karpatach Zewnętrznych są poziomami korelacyjnymi (Jucha, 1958; 1969, Koszarski & Żytko, 1959, 1961; Jucha & Kotlarczyk, 1961; Haczewski, 1984, 1989), a w niniejszej pracy są one ważnym elementem stratygrafii. Analizy mikropaleontologiczne wykorzystano na próbach pobranych z kilku profili w obrębie wspomnianej synkliny, tj.: w profilu Dźwiniacza Górnego (Fig. 3A, 4), w 2 profilach wokół Kiczery Dydiowskiej (Fig. 3B, 5) i w profilu Czereszni (Fig. 3C i 6). Ponadto wykorzystano dane z profilu Sanu w rejonie Dźwiniacza Górnego, będące wcześniej przedmiotem osobnej publikacji (Bąk, 1999). Zespoły otwornic opisano z kilku serii warstw nadotryckich, których granice stanowią horyzonty wapieni kokolitowych oraz wydzielono dodatkowo najwyższą część warstw nadotryckich, którą charakteryzuje odmienny zespół taksonów.

Opis:
The article presents a geotourism valorisation of selected quarries located in different mountainous regions in southern Poland, diverse in geological and tectonic terms. The regions of Kłodzko (with quarries Kletno I, Krzyżnik, Sinica, Czarne Urwisko, Szczytna Zamek) and of Cieszyn Foothills (quarries Na Jasieniowej, Na Mołczynie, Grota na Rudowie, Nad Kalembianką, Ondraszkowa Dziura) were proposed as a case study. The survey describes the most exposed disused quarries of marble, gneiss, sandstone, teschenites and Cieszyn limestone of high natural and cultural significance. As a result of the geotourist valorisation, the analysed geological objects were given point score under various criteria (educational value, scientific value, visual value, location/accessibility value, cultural value, geo-infrastructural value and the value of legal protection). It was found that the discussed quarries reveal high natural and educational value, and they are very significant in education and promotion of geologically attractive areas.

Opis:
Cooperating with the countries of Central and Eastern Europe is a means of enhancing the diplomatic standing of Poland (and other states) within the international arena. The effects of such cooperation are of long-term value. The initiators of these initiatives recognized that Central and Eastern Europe is where the geopolitical status of Poland has the greatest positive effect and weight. The core goal of such cooperation in the region is to be active in joint endeavors that are aimed not just at countering the influence of Russia, but at achieving multilateral benefits for all participants.
Współpraca państw Europy Środkowej i Wschodniej jawiła się jako możliwość lewarowania pozycją Polski na arenie międzynarodowej. Efekty współpracy mogły być mierzalne dopiero w dłuższej perspektywie. Rozumowano, że w Europie Środkowej i Wschodniej rozgrywała się gra o status geopolityczny Polski na arenie międzynarodowej. Celem zasadniczym skutecznej współpracy w regionie miało być wspólne realizowanie projektów, których nie łączyło jedynie działanie przeciw (Rosji), lecz przede wszystkim na rzecz wspólnych projektów, które miały powodować bogacenie się narodów i wielostronne korzyści dla państw uczestniczących w projekcie integrującym i animującym współpracę państw Europy Środkowej i Wschodniej w ramach Europy Karpat i Inicjatywy Trójmorza.

Opis:
Vegetation of deciduous forests in the Štiavnické vrchy Mts (Central Slovakia) was studied using the standard Zürich-Montpellier approach. The numerical classification and ordination technique were applied to determine the main forest vegetation types and to find the responsible environmental drivers related to their distribution patterns, respectively. The data set including 198 relevés collected by authors in 1997-2009 and 185 relevés excerpted from literature was used to analysis. Numerical classification resulted in delimitation of fourteen vegetation types representing eleven associations with two variants and two communities within the Quercetea roboripetraeae and Querco-Fagetea classes. The major environmental gradients in variation of forest species composition were associated with moisture and nutrient content following the average Ellenberg indicator values. Along the moisture gradient, vegetation types were ordered from subxerophilous oak forests turn mesophilous mixed oak-hornbeam, beech and ravine forests to hygrophilous riparian alder forest. The results confirmed important role of soil nutrients and moisture by determination of forest vegetation in subcontinental part of Central Europe. Special attention was given to the discussion of floristical characteristics, site conditions and syntaxonomy.
