Gdów “embayment”
Opis:
The Gdów “embayment” is the most pronounced deflection along the northern boundary of the Carpathians. It is filled by the sandy clay deposits which used to be named the Skawina Formation or Chodenice beds or, locally, conglomerates (of Sypka Góra). Their stratigraphic position according to studies of foraminifers had been determined as Badenian. New results obtained from micropalaeontological material sampled at three exposures near Wiatowice, Jawczyce (Giewont) and Gdów (Sypka Góra), and based on boreholes, indicate a much younger age of for the deposits infilling the Gdów “embayment”. These studies show that the surface deposits are not older than Late Sarmatian/Pannonian (Serravalian/Tortonian). They also suggest a much later time for the last stages of the thrusting of the Carpathian Mountains over the Carpathian Foredeep.

Opis:
In the early 20th century, relics of Pleistocene mammals were found near the village of Starunia. Gravity surveys performed in the place of the discovery revealed a low-density bed in the Miocene Vorotyshcha salt-bearing beds. The lowered density resulted from high halite content and probably an increased number of ozokerite veins. The localization of zoological relics can be attributed to the existence of this bed. Surface gravity surveys enabled scientists to determine its course and horizontal range. Gravity surveys also confirmed the existence of the Rinne fault. In the western part of the study area gravity modelling showed an interface between Miocene Vorotyshcha salt-bearing beds and Sloboda Conglomerates, differing in average bulk density. Geologic data indicate that this interface may have the form of an overthust rather than of a fault.

Opis:
The Carpathian Foredeep in Poland is divided into two parts, eastern and western, with different tectonic frameworks and conditions of the Neogene sedimentary fill. The boundary is the so-called Krakow Ridge associated with the contact of two regional tectonic units: Upper Silesian and Malopolska blocks. The width of the Foredeep varies regionally and significantly differs in the western and eastern parts. It was developed within the epi-Variscan platform. Two zones can be distinguished in the Foredeep: the inner (older) zone and the outer zone. The subject of the presented work is the eastern part of the outer zone of Foredeep located in front of the head of the Carpathian thrust and filled mainly by autochthonous Miocene formations. The meridional width of this zone of the basin varies from about 10 km in the vicinity of Krakow to nearly 100 km in the central part. Its tectonic framework is defined from the south and south-west by marginal structures of the Carpathian overthrust and tectonic units of the folded Miocene. From the north-east and north-west, the border is marked by a system of faults in the foreground of Roztocze Upland and the Holy Cross Mountains. In the Sub-Cenozoic basement, a set of large faults of NW-SE length, with different times of formation and activity, is marked. These faults locally define horst structures and tectonic grabens. Some of the faults continue under the Carpathians, under which there is also a system of transversal faults in relation to the main axis of the orogeny. The influence of the tectonic structures of the basement is noticeable within the Miocene cover by faults disappearing towards the surface and continuous deformations of the adaptive type. The outer foreland basin is filled with marine molasse type deposits of the unfolded autochthonous Middle Miocene with a thickness of up to approx. 3.500 m. The complex of Miocene formations is formed, in the lower, south-western and central part, by strongly differentiated submarine fan deposits accompanied by basin plain formations and gravitational flow deposits, including turbidite deposits characteristic of flysch sedimentation. The outer part of the fans smoothly transitions into the zone of fine-clastic sedimentation of the basin plain. Above the complex of submarine fan sediments, there are thick complexes of sediments of deltaic origin, which are also intensively variable facies, creating a set of channel (coarse-grained) and extra-channel (finegrained) facies. The highest, relatively thin part of the sediments is formed by shallow coastal shelf formations. Submarine fans and river deltas developed mainly in the zone of the south-western and southern coasts of the Miocene reservoir, surrounded by river mouths providing an abundant supply of material from the rising and eroded Carpathians. In the north-eastern and locally even in the middle part of the basin, sediments may appear, for which the feeding area was located in the hinterland of the northern and north-eastern coast of the Miocene Sea. The limited scope of extraction of drill cores resulting from the exploratory and exploitation nature of drilling makes it necessary to use borehole and surface geophysical data to reconstruct the depositional architecture. Processing and interpretation of geophysical data for a complex of Miocene sediments with such characteristics are problematic and ambiguous. Numerous sources of sedimentary material supply in the form of river mouths and submarine channels cause a significant diversification of the depositional architecture of the Miocene basin, making it difficult to trace uniform stratigraphic and lithological and facies boundaries. Sedimentary conditions cause, on the one hand, a certain monotony of the sediments, dominated by clastic formations, enriched by evaporate sediments horizons, and on the other hand, great lateral and depth facies differentiation. Geophysical well-logging data allows to recognize the lithological and facies variability of sediments and to determine the sequence of changes along the borehole trajectory. Seismic reflection data was used to track lateral variability. For the seismic reflective method, the reflective boundaries, characterized by a significant, abrupt change in acoustic impedance, are of primary importance. Within the Miocene basin, numerous reflective boundaries with high lateral variability and non-obvious stratigraphic identification are observed. In a complex of siliciclastic deposits, seismic wave reflections are recorded from the boundaries separating fine-grained lithofacies and medium- and coarse-grained facies. Due to the dominance of deltaic sediments and submarine fans in the depositional architecture of the Miocene complex, the regional continuity of such boundaries is problematic, and their unambiguous stratigraphic identification is practically impossible. To sum up, intense lithological and facies variability of clastic deposits, both lateral and vertical, should be expected within the Miocene complex. The sediments of individual fragments of submarine fans and deltas overlap each other, and there may also be overlaps with the sediments of neighboring fans. Such characteristics of the complex translate into a variable seismic pattern with numerous reflective boundaries and intense lateral variability of the seismic signal characteristics

Opis:
The cave of Smocza Jama located in the centre of Kraków is developed in the Wawel Horst built of Upper Jurassic limestone and surrounded by grabens with Miocene clays. The cave is composed of two series: the old one has been known for ages and the new one was discovered when an artificial shaft was mined in 1974. The new series comprises small chambers separated by intervening thin walls while the old series consists of three connected together spatial chambers. The cave abounds in extensively developed solution cavities – cupolas and ceiling pockets. The internal fine-grained deposits, predominantly representing clay fraction are built of illite, mixed layer illite-smectite, kaolinite and iron oxides. They are probably the residuum after dissolution of Jurassic limestone. The cave originated in phreatic condition due to water input from below. The new series represents juvenile stage of cave evolution. The water rose through fissure-rifts located in chamber bottoms, circulated convectionally within particular chambers, finally led to bleaching of intervening walls, and hence to connection of the neighbouring chambers. The evolution of the old series is far more advanced. The rounded solution cavities imply that the cave was formed by water of elevated temperature. The lack of coarse-grained fluvial deposits, Pleistocene mammal remains and Palaeolithic artefacts prove that the cave was isolated since its inception till Holocene time. The cave originated due to artesian circulation, when the Wawel Horst was covered by imper- meable Miocene clays. A foreland basin with carbonate basement, filled with fine-grained molasse-type deposits seems to be particularly favourable for the development of artesian caves.

Opis:
Despite the increasing technological level of the reflection seismic method, the imaging of fold and thrust belts remains a demanding task, and usually leaves some questions regarding the dips, the shape of the subthrust structures or the most correct approach to velocity model building. There is no straightforward method that can provide structural representation of the near-surface geological boundaries and their velocities. The interpretation of refracted waves frequently remains the only available technique that may be used for this purpose, although one must be aware of its limitations which appear in the complex geological settings. In the presented study, the analysis of velocity values obtained in the shallow part of Carpathian orogenic wedge by means of various geophysical methods was carried out. It revealed the lack of consistency between the results of 3D refraction tomography and both the sonic log and uphole velocities. For that reason, instead of the industry-standard utilization of tomography, a novel, geologically-consistent method of velocity model building is proposed. In the near-surface part, the uphole velocities are assigned to the formations, documented by the surface geologic map. Interpreted time-domain horizons, supplemented by main thrusts, are used to make the velocity field fully-compatible with the litho-stratigraphic units of the Carpathians. The author demonstrates a retrospective overview of seismic data imaging in the area of the Polish Carpathian orogenic wedge and discusses the most recent global innovations in seismic methodology which are the key to successful hydrocarbon exploration in fold and thrust regions.

Two-dimensional diagrams of the first and second pressure restoration curves in the semi-logarithm coordinate system were taken into account. The determined linear regression equations of these sections give simultaneously the extrapolated value of the reservoir pressure and the directional coefficient. The “logarithmic approximation” method used in hydrogeology was used to determine the radius of the perimeter zone with altered permeability of the water-bearing rocks of the Mesozoic.

Geological setting and precipitation triggers seem to be obvious parameters controlling landslides, but their relation to individual sliding processes has not been clear. We take on interdisciplinary approach (combining Earth science methods with an engineer ing-geotechnical approach) to examine sliding processes in the Kawiory landslide in the Polish Carpathians. Field parameters were obtained from inclinometer monitoring, meteorological records, piezometer data and geomechanical tests. Numerical simulation of the landslide development was performed, both for the reconstruction of the internal deformation phenomena on the slope and for approximate prediction of its future behaviour. An empirical formula describing the relationship between the depth of groundwater level (GWL) and precipitation is presented. The case study showed that for the ob served quasi-continuous creep, the depth and in particular the intensity of GWL fluctuations might be crucial.

Opis:
Alabaster is a rock with low hardness, high coherence, fine-crystalline development and forms an optically “warm” surface when polished. It has been used as a sculpting, decorative and architectonic stone, often by civilizations of the Mediterranean Sea Basin. Alabaster in the architecture and sculpture of Kraków is mainly from the Middle Miocene (Badenian) and comes from deposits within the Ukrainian Carpathian Foredeep Basin, chiefly along its northern margin in the “Podolia rim”. It was quarried around the mid-part of the Dnister River and its tributaries, from Lviv (Lwów) to Khotyn (Chocim), and mostly at Zhuravno (Żurawno). The alabaster quarried here was called Ruthenian, Polish, or Lvov “marble”. Small quarries were also located at the front of the Carpathian overthrust, including the known deposit at Łopuszka Wielka. The Miocene alabaster has shades of white, yellow, green, brown, usually with differing spots or veins; often the rock is brecciated and partly semi-transparent. Alabaster has been quarried in the Polish Republic since the 16th century, peaking (also in finished stone products) between the world wars. The authors present examples of alabaster usage in ecclesiastical edifices of Kraków, for instance in the Wawel Cathedral, St. Mary’s Church, the churches of Dominican, Carmelite and Missionary clergy, and also in some secular buildings, e.g. the Jagiellonian Library.

The pollen spectra of22 samples were determined. The pollen diagram was divided into 7 local pollen assemblage zones (L PAZ). Interglacial climatic optimum was recorded with the Eemian type of vegetation in the T-4 zone. The coldest conditions occurred during the accumulation of loess, which separates the interglacial and interstadiał soils.

Opis:
The region between the Wieliczka Foothills and the Beskid Makowski Mts. has yielded new data on the accumulation of loess-like deposits during the Vistulian Glaciation. The grain-size distibution and the heavy mineral composition, particularly the significant presence of amphiboles, indicates on aeolian origin for these silty deposits. The silt was most probably derived from glaciofluvial deposits in the Carpathian forelands. Among the Quaternary deposits which accumulated during the Vistulian Glaciation and Holocene, three horizons of loess-like deposits (correlated with the lower, middle and upper younger loesses of the Lublin Upland), three horizons of solifluction deposits, and three horizons of deluvial deposits were distinguished. The accumulation of seven alluvial successions in the Raba and Harbutówka River valleys encompasses a large part of the Quaternary - from the South Polish Glaciations (terraces VII and VI) up to the Holocene (terraces II and I). The lithostratigraphy of the slope deposits (solifluctional and deluvial) and loess-like deposits has been estabilished mainly on the basis of 14C dates of the palaeosol horizons. One of these dates, combined with palynological analysis, confirmed the existence of a warmer period in the Denekamp Interstadial (31 200 +/- 1000 years BP in the Harbutowice-1 section). The dates obtained fromthe Jastrzębia-1 (20 760 +/- 300 years BP) and Polanka-1 (20 980 +/- 310 years BP and 14 510 +/- 150 years BP) sections point to periods favouring the development of soils in the younger and terminal parts of the Younger Pleniglacial. These results, consistent with the dates obtained by other investigators, point to the existence of a warmer period (between 24-20 ka BP) in southern Poland during the maximum development of the ice sheet (Main Stadial) during the last glaciation in northern Poland.

Opis:
The facies variation of the Badenian sulphate deposits in the Polish Carpathian Foredeep Basin reflects distinct depositional and diagenetic environments. In these environments the primary sulphate (mainly gypsum) was deposited and then underwent different pathways of diagenetic evolution, recognized on the basis of sedimentological, petrographic and geochemical studies. Diagenetic sulphate facies (anhydrite and secondary gypsum) formed in successive stages: syndepositional (the depositional stage), early diagenetic (at the surface and during shallow burial) and late diagenetic (during deeper burial and exhumation). Most anhydrite deposits show sedimentological and petrographic features characteristic of a diagenetic facies formed by replacement (anhydritization) of the precursor gypsum deposits. Four basic genetic models of anhydrite have been proposed: (1) syndepositional interstitial anhydrite growth de novo, (2) syndepositional anhydritization (via nodule formation and pseudomorphous replacement), (3) early diagenetic anhydritization (displacive anhydrite growth), and (4) late diagenetic anhydritization (replacive anhydrite growth). The succession of diagenetic processes and their paragenetic relationships within the Badenian sulphate deposits display a complex diagenetic evolution. Many controlling factors, such as a palaeogeographic setting, tectonic activity, geostructural constraints and physico-chemical changes of the pore fluids, related to sedimentary and diagenetic environments, have been involved in the sulphate diagenesis. The results may be applied to other ancient evaporite basins including the marginal gypsum deposits and anhydrite in the more buried, basinward part.

Opis:
The study is focused on the taxonomic inventory of an intriguing bivalve fauna from the Lower Oligocene Menilite Beds (Dynów Marls) within the Silesian Nappe, Polish Outer Carpathians. Sixteen bivalve species have been identified within the material collected in two small quarries in Jabłonica Polska near Krosno. Stratigraphic and geographic distributions of all recognized species are considered. This assemblage, the first of this kind in Poland and one of three recognized in the Outer Carpathians, shows clear affinities to coeval typical Solenovian faunas from Ukraine to Kazakhstan, with particular comparison made to bivalve faunas from the Menilite Formation (Subchert Member) within the Boryslav-Pokuttya Nappe, Ukrainian Outer Carpathians. Moreover, this study presents an overview of the main aspects and definitions of the date of the Paratethys origin. The main criterion used to define the time of the Paratethys birth is the distinct faunal turnover from the moderately diverse boreal or Tethyan bivalve faunas populating particular basins of the Northern Peri-Tethys in the earliest Oligocene to the uniform, highly endemic fauna inhabiting the newly formed semi-closed basin. This vast inland sea, named Paratethys, was populated by representatives of eight euryhaline bivalve families. They are characterized by extinct Paratethyan genera, such as Bessia Kojumdgieva et Sapungieva, Merklinicardium Popov, Korobkoviella Merklin, Urbnisia Goncharova, Ergenica G. Popov and Janschinella Merklin.

Opis:
In Quaternary sediments filling the Velyky Lukavets River valley, at the abandoned ozokerite mine (= Ropyshche) in Starunia, perfectly preserved carcasses of large mammals were discovered in the first half of the 20th century. The study area includes a fragment of the valley between Molotkiv and Starunia, and its close vicinity. The area belongs to several morphostructural and geomorphic units of the Outer Eastern Carpathians and the Carpathian Foreland. The asymmetric, subsequent valley is a part of the Mizhbystrytska Upland, where flattened ridges and flat bulges represent fragments of planation surfaces: the upper (the Krasna level), elevated 170 m above the valley bottom and linked with the Late Pliocene, and the lower one (the Loyova level), rising at 100 m and linked with the Eopleistocene. Several flat surfaces are visible on valley slopes, probably representing river terraces formed before the Late Pleistocene. The valley attained its maximum depth during the Eemian Interglacial (OIS 5e). In the Ropyshche area, probably three terrace steps built of Weichselian and Holocene sediments (OIS 5d - 1) were developed, but their top surfaces are almost completely destroyed by mining operations. The recent, meandering river bed follows the zones of decreased cohesiveness of rocks resulting from mining activity and is becoming somewhat deepened during inundations. The transported material is mostly coarse-clastic one. The two latter factors may suggest that the river is underloaded due to declining agriculture and decreasing intensity of outwash. The top surface of the sub-Quaternary basement is deformed by subsidence and collapse of mine workings, but the relief of valley bottom allows for further exploration for remnants of large mammals not only in the Ropyscche area but along the whole studied segment of the valley, as well.

Chemical composition of the brines of primary fluid inclusions in sedimentary halite (from the boreholes: P-2, P-3, P-6, P-7 and P-8) of the Badenian evaporite of the Zbudza Fm. from East Slovakian basin indicates that the basinal brines belong to the Na-K-Mg-Cl-SO4 type. The ratios of K+, Mg2+, and SO42- ions are practically the same as they were in the Badenian seawater. Taking into account the information on the chemical evolution of seawater in the Phanerozoic (Kovalevich et al., 1998) and the calculations of this evolution for the Cenozoic (Zimmermann, 2000) it is suggested that the Badenian seawater was characterized by the reduced contents of Mg (by approximately 20%) and SO42- (by approximately 40%) in comparison with the recent seawater. The postsedimentary recrystallization of salts occurred under the effect of buried brines, which inherited their composition from the primary basinal brines. The intensive recrystallization of salts occurred during the tectonic movements.
