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.

Western Outer Carpathians
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.

Silesian Beskid Block

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.

Tytuł:: Pseudo-shallow marine features in deep marine gravity-flow successions: lessons from the Menilite Beds at Skrzydlna (Oligocene; Western Outer Carpathians)

Tematy:: Oligocene
Carpathians
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.
