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:
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:
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:
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:
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.

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:
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.

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.

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.

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.

This paper concerns the identification of neotectonics structures on the basis of topographic maps analysis. The investigation parameter is valley floor width (VFW), this being applied to the drainage basin of the BeCva river, Czech Republic. It is firstly necessary to determine the theoretic profile of the VFW downstream increment. For its construction the magnitudo was used (Shreve, 1966). Then, the differences between the real VFW and the theoretical VFW were calculated. The differences were classified according to the associated bedrock lithology. The sections where differences were widely divergent from the average are assumed to be have been affected by neotectonics.

Opis:
The Outer Carpathian Basin domain developed in its initial stage as a Jurassic-Early Cretaceous rifted passive margin that faced the eastern parts of the oceanic Alpine Tethys. Following closure of this oceanic basin during the Late Cretaceous and collision of the Inner Western Carpathian orogenic wedge with the Outer Carpathian passive margin at the Cretaceous-Paleocene transition, the Outer Carpathian Basin domain was transformed into a foreland basin that was progressively scooped out by nappes and thrust sheets. In the pre- and syn-orogenic evolution of the Outer Carpathian basins the following prominent periods can be distinguished: (1)Middle Jurassic- Early Cretaceous syn-rift opening of basins followed by Early Cretaceous post-rift thermal subsidence, (2) latest Cretaceous- Paleocene syn-collisional inversion, (3) Late Paleocene toMiddle Eocene flexural subsidence and (4) Late Eocene-EarlyMiocene synorogenic closure of the basins. In the Outer Carpathian domain driving forces of tectonic subsidence were syn-rift and thermal post-rift processes, as well as tectonic loads related to the emplacement of nappes and slab-pull. Similar to other orogenic belts, folding of the Outer Carpathians commenced in their internal parts and progressed in time towards the continental foreland. This process was initiated at the end of the Paleocene at the Pieniny Klippen Belt/Magura Basin boundary and was completed during early Burdigalian in the northern part of the Krosno Flysch Basin. During Early and Middle Miocene times the Polish Carpathian Foredeep developed as a peripheral foreland basin in front of the advancing Carpathian orogenic wedge. Subsidence of this basin was controlled both by tectonic and sedimentary loads. The Miocene convergence of the Carpathian wedge with the foreland resulted in outward migration of the foredeep depocenters and onlap of successively younger deposits onto the foreland.

Opis:
The present account summarizes the results of lithological and facies analysis of representative sections of the Godula Formation, in order to contribute to the understanding of the lithofacies structure of this formation, the processes involved in its development and the character of the depositional environment. The sedimentology of different parts of the Godula Formation was investigated in six representative sections in the western and central parts of the Moravskoslezské Beskydy Mts. The Godula Formation is made up mainly of Upper Cretaceous siliciclastic turbidites and was formed during the most significant depositional phase of the filling of the deep-sea Silesian Basin. On the basis of sedimentological research, five facies classes (including four subclasses) were defined: 1) conglomeratic sandstones, 2) sandstones, 3) sandstones with mudstones, 4) mudstones with sandstones and siltstones, and 5) mudstones with siltstones. The methodology of facies analysis allowed the identification of several facies association, corresponding to the medial and distal parts of a turbidite fan and associated siliciclastic apron. The facies of depositional lobes, lobe transitions and the apron are described. The sandstone and mudstone facies (F3) occurs mostly in the depositional lobes. The sandstone facies (F2) and mudstone with sandstone and siltstone facies (F4) are present only to a lesser degree. The facies of the lobe transitions include lithologic associations of the lobe fringe and channel levee environments. They comprise mainly the mudstones with sandstones and siltstones (F4) and the mudstone with siltstone facies (F5). In the apron deposits, the sandstone facies (F2) and the conglomeratic sandstone facies (F1) predominate. Palaeocurrent analysis from measurements made in selected profiles showed that in the Moravskoslezské Beskydy Mts., the dominant direction of sediment transport was from SW to NE. After applying correction of the known counterclockwise rotation of the nappes of the Outer Carpathians, this corresponds to a longitudinal direction along the original axis of the basin.
