Opis:
Krynica Spa is situated in the southern part of the Magura Nappe, at the boundary between the Bystrica and Krynica subunits. The Bystrica succession is composed of the Middle to Upper Eocene strata of the Magura Formation, while the Krynica succession is built up of the Palaeocene through Middle Eocene strata that belong to the Szczawnica, Zarzecze and Magura formations. The Bystrica and Krynica subunits contact along a sub-vertical, NE-dipping fault. In the study area, several NE-trending transversal faults cut both the Bystrica and Krynica subunits into several blocks. The Krynica area is seismically active, as shown by the most recent, moderate- intensity earthquakes which occurred in 1992-1993, of epicentres situated NE of Krynica Spa. The region is rich in natural mineral water springs which are confined to a tectonic block bounded by the Tylicz and Krynica faults.
Uzdrowisko Krynica jest usytuowane w południowo-wschodniej części płaszczowiny magurskiej na styku podjednostki (bystrzyckiej) i krynickiej (Fig. 1). W badanej przez nas zlewni Kryniczanki utwory strefy bystrzyckiej występują jedynie fragmentarycznie, w NE części obszaru badań. Do strefy bystrzyckiej (sądeckiej) należą wyłącznie utwory formacji magurskiej wieku środkowo-późnoeoceńskiego, o łącznej miąższości stratygraficznej 1150– 1250 m. Są to: ogniwo z Maszkowic (piaskowce gruboławicowe z przeławiceniami margli łąckich), ogniwo łupków z Mniszka (łupki pstre i cienkoławicowy flisz) oraz ogniwo piaskowców popradzkich ("piaskowce zuberowskie"). Strefa krynicka reprezentowana jest przez paleoceńsko-środkowo-eoceńskie utwory formacji szczawnickiej (cienko- i średnioławicowy flisz), zarzeckiej (cienkoławicowy flisz z ogniwem piaskowców krynickich) oraz magurskiej (piaskowce gruboławicowe). Niepełna miąższość utworów strefy krynickiej wynosi co najmniej 1300 m. Podjednostki bystrzycka (sądecka) oraz krynicka kontaktują ze sobą wzdłuż pionowego lub niemal pionowego, zapadającego na NE uskoku, zwanego "dyslokacją krynicką". Uskoki poprzeczne o przebiegu NE–SW dzielą obie podjednostki na kilka bloków. Między Czarnym Potokiem a Słotwinami wąski półrów tektoniczny towarzyszy uskokowi słotwińskiemu. W okolicach Krynicy notowane były w latach 1992–1993 wstrząsy sejsmiczne. Epicentra tych wstrząsów grupują się wzdłuż uskoków poprzecznych o orientacji NW–SW oraz dyslokacji krynickiej.

Opis:
The Western Outer Carpathians flysch of Poland comprises clasts of crystalline rocks representing source areas that supplied sedimentary basins with clastic material. Zircon from quartz syenite and granite cobbles representing the Silesian Ridge, the currently unexposed source area located at the southern margin of the Silesian Basin, yielded uniform U-Pb dates of 604š6 Ma and 599š6 Ma. These are interpreted as the age of igneous crystallization. Similarly, zircon from a gneiss cobble derived from the northern source terrain gave 610š6 Ma date, which is interpreted as the age of crystallization of the granitic protolith to the gneiss. The Neoproterozoic magmatism is interpreted to have occurred at the Gondwana active margin.

Opis:
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.

Opis:
Sixteen bentonite layers of Eocene–Oligocene age were sampled at thirteen sites in accretionary-wedge turbidite sequences, in the three innermost nappes of the Western Outer Carpathians. K-Ar dating was carried out for five of these layers to obtain the maximum burial ages. All of the ages obtained are older than the stratigraphic ages of the host strata. This relationship is due to significant contamination of the bentonites with non-authigenic minerals. This contamination resulted from rapid sedimentation during synsedimentary folding, which is a common feature in accretionary wedges. It follows that the K-Ar dating of bentonite layers in the turbidite sequences of accretionary wedges should be largely restricted to the very distal facies of turbidites or to pelitic intercalations within the turbidites.

Opis:
The structure of the Magura Nappe, within the zone of maximal bending of the Western Outer Carpathians, is described; investigations were concentrated mainly in the Beskid Wyspowy Subunit. A zone, bounded to the north and south by duplexes, comprises large characteristic synclines (Snieznica, Lubogoszcz, Szczebel, Klimas, Lopien, Cwilin, Lubon Wielki). These appear on maps as isolated "island mountains", in the Beskid Wyspowy Subunit. These synclines contrast strongly with the belt-like distribution of regional folds to the west and east of the area. The synclinal massifs developed gradually. Fold belts several hundred metres long developed in the first phase of overthrusting of the Magura Nappe, with horizontal N-S compression dominant. Thrusts separating the individual subunits developed when the face of the overthrusting Magura Nappe stopped and the stress continued to push its southern parts forwards. The next phase, with continuing horizontal N-S stress included the development of strike-slip faults and the bending of the Carpathian Arc, resulting in extension of this part of the orogen. The syncline zone within the Beskid Wyspowy Subunit underwent disintegration and particular blocks became independent. Rotation of blocks with individual synclines took place along fault zones. In the part of the Polish Outer Carpathians investigated this stage is also characterised by a change of compression from N-S to NNE-SSW. Due to the uplift of this part of the Carpathians, strike-slip faults changed into dip-slip faults in the terminal part of this phase. reconstruction.

Opis:
This paper presents new results of a detailed structural analysis of the bedrock of the Vistula source area within the Silesian Beskids (Outer Western Carpathians, S Poland). The bedrock of the study area is composed of the Upper Cretaceous flysch series of the Upper Godula Beds and Lower Istebna Beds. The study area is located on the southern limb of the Szczyrk Anticline within the Silesian Beskid Block. The research is based on cartographic field work and remote sensing analysis of a digital elevation model from LiDAR data. The structural analyses were supported by the extraction of the topolineaments and their spatial analysis. The results presented show that the monoclinal bedrock structure of the study area can be characterized by a systematic joint pattern, which determined the existence of faults and fault zones. Moreover, detailed analyses show differences in fracturing of the sedimentary strata and the existence of hidden fracture zones, not visible in the previous map view. Most of the faults are related to an orthogonal joint system, whereas the transverse and longitudinal faults are connected with fold and thrust structures that are exposed in outcrops and reflected in the topography. Kinematic analysis shows that the NW–SE-trending transverse faults underwent dextral movements, while the ENE–WSW-trending longitudinal faults recorded sinistral displacements. Furthermore, older strike-slip and oblique-slip displacements along faults were overprinted by normal dip-slip faulting. The new tectonic and relief data show no existence of the Gościejów Syncline in the northern part of the study area, which was depicted on previous maps. In conclusion, normal faulting and damage of the bedrock along fracture zones are interpreted as being related to the posttectonic, gravitational collapse of the rock massif. Its detailed recognition is very important for the further study of relationships between bedrock structure and mass movement characteristics, such as the geometry and kinematics of landslides.

Opis:
Quite common in publications devoted to the marine and lacustrine environments are differences of opinion on bathymetry of the basin receiving detrital sediment, especially when sedimentary structures are interpreted as indicators of specific depth-defined environments (following classic textbooks). However modern studies of deep-water environments, experimental work, modelling and numerous outcrop studies of ancient successions mitigate against such an approach. In this respect, the flysch succession of the Menilite Beds strata at Skrzydlna, which contains a variety of features that can confuse a cursory observer seems to serve as a universally applicable example. The succession at Skrzydlna records deposition in the western part of the synorogenic Dukla Basin during the Oligocene. The Menilite Beds are considered by most authors as deep marine deposits (the bathyal zone). The exposed section, almost 200-metre thick, is divided into three lithological intervals, each of which represents a radically different type of sedimentation. These are: i) a fine-grained association of terrigeonous and hemipelagic sediments; ii) infill of a canyon incised by about 40–50 m into the underlying strata, wider than outcrop and dominated by an olistostromal succession of debris flows with pebbles, boulders, slide and slump sheets; iii) succession of turbidites forming three fining-upwards sequences and ranging from thick, massive, amalgamated sandstones deposited by high-density flows in laterally migrating outcrop-scale channels, through ‘normal’ turbidites forming complete Bouma sequences (Ta-e), containing dunes and fining to Tce in the uppermost associations of thin-bedded sandstones and shales. These features suggest rapid uplift of the source area resulting in canyon incision and sudden onset of the olistostrome deposition that evolved upwards into proximal turbidite-fan sequence, which subsequently retrograded due to decreasing intensity of supply. The oldest interval (i) consists of predominantly finegrained facies, most characteristic of the Menilite Beds at their regional development. These are dark mudstones deposited in anoxic to dysoxic conditions and containing thin layers of fine-grained sandstones — turbidites with Bouma Tab; Tbc; Tabc; Tabe intervals, a 2–3 m thick intercalation of massive amalgamated sandstone, dark cherts, and locally silicified marls and limestones. The latter contain isolated lenses of medium-grained sandstone current ripple marks indicating three palaeocurrent directions. Two sets represent bipolar distribution of palaeocurrents, typical of shallow sea/ shelf sediments reworked by tidal currents. However, these are interpreted here as the products of tidal currents reworking bottom sediments of the bathyal zone, the case known from contemporary environments. In this context, the third direction, perpendicular to the bipolar flows does not represent reworking by littoral current on shelf but deep marine contour current. The main channel, or canyon (ii) incised into the slope sediments fed the depositional system with olistostrome deposits supplied from the rapidly uplifted source zone. Above there is a thinning upwards, turbidite sequence of four sub-complexes (A-D): A – conglomerate and sandstone fill three laterally migrating narrow, outcrop-scale erosional channels with a maximum depth of 15 m; B  – two shallow (up to 2 m deep) distributary channels filled with very thick, massive or normally graded sandstones; C  – turbidites Tb, Tc, Tbc with single occurrences of hummocky-like cross stratification and sandstone beds forming dunes at the mouth of distributary channels; D  – less ordered interval of thick-, medium- and thin-bedded sandstones interbedded with mudstones, forming various incomplete sequences of Bouma intervals. Interbeds of hummocky-like cross stratification, commonly found on the shelf, are interpreted in the deep-sea environment as the effect of Kelvin-Helmholtz instability or other complex flow processes, e.g. reflections of turbidity currents. A few occurrences of ripplemarks symmetrical in outer shape show unidirectional cross-lamination in cross section. These were modified by erosion that could have resulted from occasional extremely violent storms or flow reflections off channel margins. In spite of the external shape reminiscent of symmetrical ripplemarks these features do not possess the internal structure of composite cross laminae characteristic for oscillatory reworking of sand by prolonged, rhythmic action of waves. Solitary current ripplemarks showing flow directions opposite to the main transport direction are antidunes or deposits of currents reflected/deflected by channel sides. In summary, in spite of geometrical and structural similarity to the features traditionally considered as formed on shelf, the structures described here, assessed in association with facies and evidence referred to in the introductory paragraphs, fall into the category of deposits known also from below the ‘normal’ wave base and below the shelf edge, i.e. in the slope region. Hence from deep-sea environment for which the occurrence of bipolar currents, dunes, hummocky cross-stratification and symmetrical ripplemarks are neither typical nor diagnostic, but do exist.

Opis:
At the end of the Jurassic and beginning of the Cretaceous in the Western Outer Carpathians (WOC) rift-related extension led to development of: the deep marine grabens with flysch and pelagic sedimentation, the zones of shallow marine carbonate sedimentation, and the elevated horsts, supplying the basins with sediments. Transition to the Early Cretaceous and Cenomanian post-rift thermal sag stage was responsible for a general ceasing of tectonic activity in the source areas and unification of the previous sub-basins. In Barremian–Albian time, the northern, external sources for sediments were uplifted due to compression, presumably caused by the orogenic collision in the Middle and Outer Dacides and/or collision related to subduction of the Penninic Ocean. The Silesian Ridge, rapidly elevated and eroded during Late Cretaceous and Paleocene, is interpreted here as an active thick-skinned thrust belt. Nappe stacking in that area and stress transmission towards foreland caused flexural subsidence of the proximal zone (the inner Silesian Basin) and uplift in the distal zone (including: the outer Silesian Basin, the Subsilesian facies zone, the Skole Basin and the northern sediment source areas). The Eocene alternating shallow marine deposition in the Silesian Ridge and its exposition for erosion is interpreted as controlled by both eustatic sea level changes and episodic tectonic activity. At this time new thick-skinned thrust belt developed south of the Magura Basin, which supplied vast amount of detritus for the Magura Beds. The Eocene tectonic shortening and deformations in the Southern Magura Ridge and development of the accretionary prism caused flexural bending of its broad foreland, subsidence and relative facies unification of the basins and decrease of activity of the source areas located north of the Magura Basin. The Oligocene progress of plates/microplates convergence and relocation of the zone of tectonic shortening towards the north led to compressional uplift of the source areas located both to the north of the WOC basins and to the south of the Silesian facies zone, the later composed of crystalline basement, as well as sediments of the Magura Unit. That sources supplied with detritus the Upper Oligocene–Llower Miocene Krosno Beds, being a diachronic continuation of synorogenic deposition of the Magura Beds. During the Late Cretaceous–Paleogene–Early Miocene, an important tectonic shortening across the WOC took place, accommodated mainly in the source areas. This indicates that the palaeogeographic relationships between the Silesian Basin, the Magura Basin and the Central Carpathian Paleogene Basin were changing during the Cretaceous and Cainozoic. In the time span of Albian to Oligocene in the zone palaeogeographically located between the Magura Basin and the Central Carpathians three separate source areas were active, each characterized by a different geological setting. These sources were replacing each other in time, suggesting significant collisional and/or strike slip reorganisation of the zone during that period. The collision of the WOC evolved in time from thick-skinned mode during the Late Cretaceous–Paleogene to thin-skinned one during the Middle Miocene.

The area studied, known as the Małe (Little) Pieniny Mts., belongs to the Pieniny Klippen Belt (PKB), a suture zone that separates the Central Carpathians from the Outer Carpathian accretionary wedge. Along its northern boundary the PKB is separated from the Paleogene to Early Miocene flysch deposits of the Magura Nappe by a narrow, strongly deformed belt belonging to the Grajcarek tectonic Unit. This unit is composed of Jurassic, Cretaceous and Paleocene pelagic and flysch deposits. The Klippen units of the PKB are represented by Jurassic–Lower Cretaceous carbonate deposits overlain by Upper Cretaceous variegated marls and flysch deposits. We describe geological and biostratigraphic evidence concerning the palaeogeographic, stratigraphic and structural relationships between the Pieniny Klippen Belt and the Magura Nappe, that significantly modify previously held views on the evolution of the Małe Pieniny Mts. and the Polish sector of the PKB.

Opis:
The study focuses on Upper Cretaceous - Palaeocene deposits from the Beskid Śląski mountain range in southern Poland constituting the Istebna Beds. The Istebna Beds, also referred to as the Istebna Formation, are part of the Silesian tectonic unit, which forms the Outer Carpathian fold-and-thrust belt (part of the Alpine-Carpathian system). The results of qualitative and quantitative lithological-sedimentological studies were the basis for the interpretation of lithofacies types, sedimentary processes and palaeoenvironment as well as for the reconstruction of the architecture of the depositional system. The analysis conducted on the basis of field description of the deposits shows the prevalence (nearly 70%) of siliciclastic strata representing a sandstone-conglomerate association (S-C), which is the main subject of this work. The S-C lithofacies: sandstones, gravelly sandstones, sandy conglomerates and conglomerates constitute the deposits formed mostly by mass gravity-flows such as sandy-to-gravelly debris flows. The distribution of the coarse-clastic material indicates a sediment supply from southerly directions and implies the presence of an active source area in the rear part of the Silesian Basin. A succession of the sandstone-to-conglomerate deposits with the secondary participation of other lithofacies, with a thickness of approximately two thousand metres, indicates temporary increased diastrophic activity in the Silesian Ridge (source area) and the intense denudation of this area. The uplift of the alimentation area and its destruction coinciding with enforced relative regression and the uncovering of the proximal depositional zone of the basin led to resedimentation of the older intrabasinal material and repeated mass deposition together with delivery of extraclasts of pre-existing rocks and minerals. The lithofacies development of the sandstone-to-conglomerate debrites and the related sedimentary palaeotransport directions suggest an accumulation domain in the form of a linear apron depositional system developed in a deep-water setting. Experimental modelling of subaqueous sandy flows has contributed to a better understanding of the complex genesis of deep-water sediment gravity flows developing in depositional systems rich in sand material.

The Mutne Sandstone Member occurs within the Jaworzynka Formation of the Magura Nappe depo- sits, typical for the western marginal Siary subunit. In the area north of Jeleśnia it is represented by the thick sand- stone complex. Typical and complete profile of this division is located in Mutne village next to Jeleśnia, on the slope of Janikowa Grapa Mt. This locality represents the type section for the Mutne Sandstone Member, while three others: Jaworzynka, Rychwałdek and Kuków-Rzyczki serve as reference sections. The age of the Mutne Sandstone Member was determined as Maastrichtian-Palaeocene; but only Maastrichtian is documented by foraminiferal assemblages. The Palaeocene age comes however from the superposition of this lithosom within the Magura Nappe profile. The Campanian/Maastrichtian-Palaeocene complex of Siary Subunit deposits provides the perfect example for application of supersequences to the Western Flysch Carpathian basin. It fits the Upper Zuni IV supersequence and global time slice. The Mutne type locality is also a prime geotourist attraction and object of inanimated nature proposed for protection.

Opis:
Analysis of deposition rate were performed for synthetic sections, representing the upper Jurassic to lower Miocene sedimentary fill of the Western Outer Carpathian (WOC) basins. Calculated deposition rates differs in a range of a few orders of magnitude. During Tithonian to Berriasian-early Valanginian tectonic activity of the source areas supplying the Silesian Basin was related to the mechanism of syn-rift extensional elevation and erosion of horsts. General decay of source area activity in Valanginian to Cenomanian time was caused by regional post-rift thermal sag of the WOC. The Barremian to Albian phase of compressional uplift of the source area located north of the WOC lead to increase of deposition rate in some zones of the WOC basin. In Turonian to Paleocene time thick-skinned collision and thrusting took place south and south-west (in the recent coordinates) of the Silesian Basin causing very rapid, diachronous uplift of this zone, referred to as Silesian Ridge, resulting with high deposition rate in the Silesian Basin. At that time supply of sediments to the Magura Basin from south was relatively low, and the Pieniny Klipen Belt was presumably zone of transfer of these sediments. In Eocene the zone of collisional shortening in the WOC system was relocated to the south, causing rapid uplift of the Southern Magura Ridge and intense supply of detritus to the Magura Basin. Thrusting in the Southern Magura Ridge and collisional compression resulted with flexural bending of its broad foreland, being the reason for decrease of activity of both the Silesian Ridge and the source area at the northern rim of the WOC. The Eocene evolution of the Silesian Ridge is interpreted as controlled by both episodic tectonic activity and eustatic sea level changes. Contrasting development of the Southern Magura Ridge and the northern rim of Central Carpathians during Eocene stands for a palaeographic distance between the two domains at that time. During Oligocene and early Miocene a significant increase of deposition rates is observed for the basin in which sediments of the Krosno beds were deposited. This was caused by tectonic uplift of the source at the northern rim of the WOC, as well as the Silesian Ridge and the partly formed Magura nappe. The Miocene molasse of the WOC foredeep basin is characterised by notably higher maximum deposition rates than ones calculated for the flysch deposits of the WOC.

Opis:
Fossils and exotics from the Albian-Cenomanian deposits of the Western Polish Carpathians are discussed in relation with changes in depositional environments. Environmental conditions were controlled by geotectonic activity, sea-level changes and also anoxic and biotic events. During the Albian-the Early Cenomanian, and in the Turonian the fall in sea level led to increased supply of coarse-grained material rich in siliceous and sometimes calcareous bioclasts and exotics. This cyclic process has contributed to changes in the marine biota. In the Albian monogenic foraminiferal assemblages with the surficial epifauna corresponding to the organic influx and oxygen deficiency (OAE 1b) were evolved into more variable associations including deep infauna, which indicated more aerobic conditions. Under these conditions also preserved planktonic and calcareous benthic fossils, which indicated the supply of terrigenous material from shallow-water environments and land. During the Albian-Turonian transition intensive subsidence and volcanic activity associated with eustatic sea-level rise led to intensive production of phytoplankton. The sea-surface productivity and enhanced upwelling resulted in expanded short-term oxygen minima at the end of the Albian (OAE 1d) and the Cenomanian (OAE 2). In the latter interval benthic forms almost extinct while siliceous and calcareous plankton survived. In the Turonian changes in sea-level and sedimentary regime led to recolonization of the basin bottom.

Opis:
Over 100 ammonites were collected from a block of bedded shallow-water Štramberk Limestone at a new location at the Kotouč Quarry, near Štramberk (Silesian Unit, Czech Republic). Berriaselline neocomitids, including Berriasella jacobi, B. oppeli, Tirnovella allobrogensis, T. cf. allobrogensis, Delphinella consanguinea, Pseudosubplanites cf. grandis and Malbosiceras cf. asper, are the most abundant species in this ammonite association. The olcostephanitid, Spiticeras blancheti, is rare. The index species for the Early Berriasian, B. jacobi, occurs in large numbers. On the basis of the present study, the upper boundary of the stratigraphic range of the Štramberk Limestone in the type area is dated as early Berriasian (ammonite Berriasella jacobi Zone). Ammonites with ages younger than early Berriasian have never been found in the Štramberk area. The deposition of the Štramberk Limestone in the Štramberk area came to an end during that period.

Opis:
Young tectonic movements in the Carpathians, both vertical and horizontal ones, display local varia- tions. The Dunajec River valley is one of the areas where this differentiation has been documented best. New data on differentiated tectonic uplift, based on the study of changing elevations of five levels of fluvial strath terraces, were obtained in the lowermost reaches of two Dunajec’s tributaries: Kamienica and Ochotnica. The results indicate a change in the rate of valley bottom incision during the Pleistocene. Initially, the rate of incision was higher in the Kamienica River valley during ca. 600–350 ka BP. Later, since ca. 130 ka BP until now, the proportion became reversed and the rate of incision was nearly twice as fast in the Ochotnica River valley than in the Kamienica River valley. This is probably related to the mobility of the overthrust of the Krynica slice onto the Bystrica slice, both building the inner portion of the Magura Nappe. Reactivation of this thrust may be a result of neotectonic activity of large-scale faults situated at the depths of 5–20 km and possibly rooted in the Palaeozoic– Mesozoic basement.

Opis:
New occurrences of bentonitized tuffites were described from numerous outcrops of the Lower Eocene flysch rocks of the Subsilesian Unit. These deposits crop out in the Żywiec tectonic window and in the tectonic windows of the Lanckorona - Żegocina Structural Zone. The bentonitized tuffites, composed of almost pure dioctahedral motmorillonite, form numerous thin layers and laminae, only occasionally exceeding 5 cm. The age of the tuffites is estimated as the Early Eocene (Glomospira div. sp. and Saccamminoides carpathicus zones) on the basis of foraminiferal assemblages. They occur in the upper part of green shales and in the lower part of the Lipowa beds that consist mainly of muddy turbidites represented by green or green-brownish shales with rare intercalations of sandstones. The sedimentary sequences with the tuffite intercalations form a lithostratigraphic level in the Subsilesian Unit called in the present paper "the Glichów Tuffite Horizon". This tuffite horizon could probably be correlated with deposits of similar age containing tuffites which are known from the Magura, Silesian and Skole nappes.

Opis:
The Oligocene flysch sequence from the Hulskie section in the Polish Outer Carpathians was palaeomagnetically examined. The flysch complex containing the Jasło and Zagórze limestone horizons revealed palaeomagnetic properties sufficient for a magnetostratigraphy to be established. The correlation of the local to the global magnetic polarity scale indicates that the Jasło limestone was deposited very close to the Rupelian and Chattian boundary i.e. ca. 28.4 Ma. In the same way, the age of the Zagórze limestone was defined as close to ca. 27.6 Ma. The entire450 mof studied section was formed between ca. 29 and 26.5 Ma. It implies an average sedimentary ratio of about 18 cm per thousand years. The palaeomagnetic directions from the Hulskie section do not display the Fisher type distribution and do not fit the reversal test and therefore cannot be used for any regional tectonic reconstruction.

W pracy przedstawiono charakterystykę stratygraficzną dolnych łupków i wapieni cieszyńskich w oparciu o zróżnicowane spektrum mikroskamieniałości. Rozmieszczenie i migracja tych mikroorganizmów do basenu cieszyńskiego, usytuowanego na południowej krawędzi Platformy Zachodnioeuropejskiej, były określone jego geotektoniczną transformacją. Pozycję niefliszowych, węglanowych utworów basenu (dolne łupki cieszyńskie i dolna część wapieni cieszyńskich) określają zespoły tytońskich mikroskamieniałości z pojedynczymi elementami późnego kimerydu. Natomiast sedymentacja węglanowych turbiditów (wyższa część wapieni cieszyńskich) miała miejsce głównie w okresie berias - walanżyn z prawdopodobną kontynuacją do (?późnego) hoterywu.
Microfossils from the Tithonian-(?Late) Hauterivian carbonate deposits of the Cieszyn Beds (Lower Cieszyn Shales and Cieszyn Limestones) are reviewed. The distribution and migration of microorganisms into the Carpathian (Cieszyn) Basin were determined by geotectonic transformation of the Cieszyn Basin situated on the southern margin of the Western European Platform. The age of the nonflysch carbonate deposition in the Cieszyn basin (Lower Cieszyn Shales, and lower part of the Cieszyn Limestones) is documented by Tithonian calcareous microfossils accompanied by Late Kimmeridgian elements whereas the development of carbonate turbidite deposition in the Beriassian - Valanginian time (Cieszyn Limestones), probably continued up to the (?Late) Hauterivian.

Opis:
The soil piping that occurs on luvisols in the vicinity of the village of Halenkovice was studied for 5 years. These piping phenomena can only be found where arable land meets the forest or a belt of shrubbery. If there is a scarp in the locality, which usually changes from 6° in the field to approximately 30° in the forest, soil pipes are more likely to occur. Before the scarp, the slope flattens out and it is almost horizontal. This factor makes it possible for the overland flow to seep into the slope. This seepage results in soil piping, which is formed in loess loam and colluvial deposits. There are about 15 sites in the vicinity of the village of Halenkovice, where soil piping occurs. In one of them, Halenkovice 1 (an area of 900 m2) we closely studied 47 partial cavities. Their internal volume is 3.8 m3. The volume of the sink holes is 23 m3. There are two types of soil pipes – vertical, which on average tend to be shorter (40 cm) and lead the water under the surface, and soil pipes parallel with the slope, which are on average 81 cm long. Water flows through the pipes during a thaw or precipitation, which often takes away the top soil. The intensity of this process depends on the intensity of precipitation, which occurs outside the growing season, when there are no crops in the fields.

Przedmiotem niniejszego opracowania jest budowa petrograficzna uwęglonej lądowej materii organicznej w skałach fliszu Karpat Zachodnich. W trakcie analizy petrograficznej materię organiczną podzielono na odmiany, mając na uwadze rozmiar szczątków organicznych. Materia organiczna reprezentowana jest przez DOM (Dispersed Organic Matter) i uwęglony detrytus roślinny. Ustalono, że zarówno DOM, jak i detrytus nie występują w skałach grubookruchowych, takich jak piaskowce gruboziarniste i zlepieńce. We wszystkich próbkach zawierających materiał węglowy dominuje grupa witrynitu, stanowiąca od 70% do 100% materii organicznej, przy udziale grupy inertynitu w zakresie od 0 do 30%. W trakcie badań próbek w świetle ultrafioletowym w żadnej nie stwierdzono macerałów grupy liptynitu. Największy udział w próbce całkowitego węgla organicznego TOC (ang. Total Organic Carbon) od 1.09% do 8.2%, wykazały warstwy krośnieńskie, grybowskie, formacja szczawnicka, beloweska i wierzowska. Wartości średniej refleksyjności witrynitu w poszczególnych jednostkach są do siebie zbliżone, choć w obrębie jednostek są silnie zróżnicowane i wyniosły odpowiednio: 0.39-0.62% w jednostce śląskiej, 0.38-0.71% w jednostce magurskiej i 0.42-0.67% w jednostce grybowskiej. Najwyższe wartości odnotowano w oknie tektonicznym Mszany Dolnej (0.67%) oraz w południowych partiach jednostki magurskiej (0.65-0.71%).
The objective of this study was a petrographic analysis of terrestrial organic matter in the Western Flysch Carpathians. During the petrographic analysis, organic matter was divided with respect to the size of organic remains into two types. Organic matter is represented by the acronym DOM (Dispersed Organic Matter) and coalified detritus. It was found that both DOM and detritus do not occur in coarse grained rocks, such as coarse sandstones and conglomerates. Vitrinite is the dominant component in all samples, it constitutes 70% to 100% of the organic matter content, whereas the inertinite group makes up the remaining 0% to 30%. No exinite group macerals were detected during fluorescence microscope analysis. Krosno beds, Grybów beds, Szczawnicka, Beloveza and Verovice formation revealed the greatest contribution of TOC (Total Organic Carbon) in the sample, which was from 1.09% to 8.2%. The random mean vitrinite reflectance values in the individual units are similar and vary from 0.39 to 0.62% in the Silesian unit, 0.38% to 0.71% in the Magura unit and 0.42% to 0.67% in the Grybów unit. The highest values were observed in the Mszana tectonic window (0.67%) and in the southern parts of the Magura unit (0.65-0.71%).

In the southernmost part of the Krynica facies zone of the Magura Nappe two new lithostratigraphic units have been established: the Poprad Member and the Kremna Formation. The Late Eocene-Oligocene age of the Malcov Formation (NP 19-NP 24) of the Pieniny Klippen Belt has also been confirmed. A Late Oligocene age (Zone NP 25 and lower part of NN1) was determined in deposits belonging to the Poprad Member of theMagura Formation, while an EarlyMiocene age (upper part of NN1 and NN2 zones) was established for the Kremna Formation. The Late Cretaceous-MiddleMiocene geotectonic evolution of the orogenic suture zone, between the Inner and Outer Carpathians, is outlined.

Opis:
Recent discoveries of ammonites in the Štramberk Limestone in the type area of their occurrence near the town of Štramberk supplement existing data on the Tithonian age of the limestones. Franconites cf. fascipartitus occurs in the lower part of the Lower Tithonian (Neochetoceras mucronatum Zone). Lemencia ciliata has a zonal character in the upper part of the Lower Tithonian. Richterella richteri is a subzonal species of the upper part of the Lower Tithonian in the Mediterranean and Submediterranean areas (Semiformiceras fallauxi Zone). All of the new discoveries are referable to the faunal associations of the Submediterranean bioprovince, and are in agreement with existing knowledge of it. Sexual dimorphism was seen in the genus Richterella, with the recognition of both macroconchs and microconchs in the type species of Richterella, i.e. R. richteri. The stratigraphic position of these recent ammonite discoveries in the Štramberk Limestone at the Kotouč Quarry does not support the stratigraphy of the limestones based on the distribution of calpionellids, as previously assumed by other authors. The recent collection of ammonites confirms that the Štramberk Limestone belongs to the lower Tithonian and lower Berriasian and also represents the lower Tithonian as a shallow-water facies.
