Opis:
Chloride waters in the Polish Flysch Carpathians are remnants of marine sedimentation water which was chemically and isotopically changed due to ultrafiltration and the release of dehydration water (diagenetic water) during the burial diagenesis of clay minerals. In the western part of the study area, the diagenetic end-member is characterized by δ18O and δ2H values of about +6.5 and –30.0‰, respectively, and Cl– content in the range of 3.8 and 13.8 g/dm3. In some fault areas, such waters migrate to the surface and mix with local meteoric waters as indicated by mixing lines in δ18O–δ2H and δ18O–Cl– graphs. In several wells of the eastern part, waters containing a significant proportion of marine water occur. However, in majority of deep wells, mixtures of diagenetic and meteoric waters of Quaternary and pre-Quaternary climates are present, as deduced from δ18O–Cl– linear relations. In most cases, they do not exhibit linear relations also expected in δ18O–δ2H graphs due to the shifts of δ2H to heavier isotopic values supposedly caused by involvement of water in the generation of hydrocarbons.

Opis:
The Crimean Mountains (CM) are regarded as part of the Alpine-Himalaya orogenic belt related to the collision of the Eurasian and African plates. Our research in the CM has allowed confirming the existence of at least two flysch formations of different ages: the Taurida Flysch Formation (Upper Triassic/Lower–? Middle Jurassic) and the Sudak Formation (uppermost Jurassic/Lower Cretaceous) in the western and eastern sectors of the CM, respectively. After the Middle Jurassic volcanism, the freshwater claystones with coal-bearing intercalations, as well as local alluvial fan conglomerates were deposited. Then, following the Oxfordian/Kimmeridgian marine transgression, three separated Tithonian/Berriasian carbonate platforms developed: Baydarska, Chatyr-Dag and Demerji/Karabi. At the turn of the Late Jurassic, the deep-water Sudak Basin (eastern sector of the CM) began to develop in the eastern periphery of the Demerji/Karabi carbonate platform. This basin, dominated by turbiditic deposition, was probably connected with the Great Caucasus sedimentary system. Finally, distal flysch sedimentation in the Sudak Basin was followed by debris-flow deposits, with huge blocks of Upper Jurassic limestones. These blocks were derived from destruction of the Karabi carbonate platform. During the Berriasian/Valanginian, the eastern sector of the CM began to subside. As a result, both carbonate platforms (western CM) and the debris flow fans of the Sudak Basin (eastern CM) were overlain by marly shales and/or distal turbidites. This type of deposition lasted until the Aptian/Albian. In the post-Albian period, the Alushta-Salgir tectonic zone was transformed into a SE-dipping thrust fault with at least 10 km amplitude of overthrusting.

W artykule omówiono możliwości oraz przedstawiono wyniki symulacji numerycznej ruchu osuwiskowego, wykonanej na przestrzennym modelu zbocza. Fliszowy masyw skalny charakteryzuje się anizotropią i — co za tym idzie — jego zachowanie zależy od orientacji struktur geologicznych w relacji do morfologii powierzchni terenu. Model dwuwymiarowy często nie pozwala na uwzględnienie takich struktur. W takich sytuacjach jedynie zastosowanie modelowania przestrzennego (3D) umożliwia stosunkowo dobre odwzorowanie przestrzennych cech ośrodka. Przedstawiono przykład analizy przestrzennej procesu deformacji zbocza osuwiskowego Kawiory, wykazując zalety metody 3D. Symulację numeryczną procesu przeprowadzono przy użyciu programu FLAC3D (Itasca, 1997), opartym na metodzie różnic skończonych.

Opis:
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:
Detrital fragments of automorphic tourmaline crystals are commonly incorporated in tests of simple agglutinated foraminifera that lived in the deep-marine Carpathian turbidite basin, in which deposition of the Hieroglyphic beds (Eocene) took place. Such grains were observed in the tests of 37 taxa representing 20 species. However tourmaline occurs in the Carpathian Flysch sediments as an accessory mineral, still it was selected by the foraminifera as the only heavy mineral to be incorporated in their tests. The proportion of tourmaline-bearing specimens in an assemblage usually amounts to a few percent, but may reach 29% in extreme cases. The particular preference for tourmaline segregation and incorporation in the test walls is shown by the following genera: Psammosiphonella, Reophax, Bathysiphon and Nothia.

Opis:
This study identifies zones with significant changes in pore water pressure influenced by landslide processes. Measurements were taken in the near-surface strata of the Carpathian flysch, in colluvium of the Siercza landslide, near Kraków. Measurement of pore water pressure in flysch deposits is complicated due to the strongly heterogeneous properties of the medium and by variable water conditions, which are strongly influenced by rainfall intensity. Pore pressure profiling was performed in six series using a cone penetration test with a NOVA Acoustic cone. The tests were carried out in the colluvium to a depth of ~6.0 m under varying water conditions. The cone pore pressure results were compared to results of inclinometer measurements in the research area. Five zones with significant differences in pore pressure have been identified. Changes in both cone pore pressure and inclinometer displacement are evident at a depth range from 1.5 to 2.5 m. Two slip surfaces are likely present in this section. Such information can be used in engineering practice for more reliable assessment of slope stability in the Carpathian flysch.

Opis:
Values of rainfall thresholds on selected shallow landslide slopes (Dział, Gwoździec) located in the Nowy Wiśnicz Foothills are determined using a physically-based slope stability model considering a long-term period of analysis (GeoSlope Inc. software). Slope stability analysis included determination of the impact of rainfall on changes of stress state within the soil substrate and their influence on estimation of mass movement risk. The slope stability calculation results have shown that the rainfall threshold values are a function of many variables, primarily the hydraulic properties of soil and rock substratum, temporal distribution of precipitation, and soil moisture content conditions in the period proceeding rainfall. The results of the calculations indicate that, in extreme cases, accumulated rainfall threshold values for the same slope can range from ~100 to 500 mm. Estimated rainfall threshold values were lower than those values reported in the literature for the Polish Carpathians, but are similar to those determined by Guzetti et al. (2007) for Central and Southern Europe.

Opis:
The Lower Carboniferous sediments of the Bardo Mts. is mainly composed of biostratigraphically undocumented flysch sequences. A cone impression was found in clayey-mudstone bed of the Srebrna Góra formation that represents one of these flysch sequences. The estimated Middle or even Upper Viséan relative age of this formation was determined based on the underlying paleontologically documented Nowa Wieś formation. The strobilus specimen is morphologically similar to cones assigned to genera Flemingites and Lepidostrobus, that were produced by arborescent lycopsids. The absence of in situ spores makes a precicse taxonomical determination of the cone impossible. The currently known stratigraphical ranges of the two genera are consistent with the previous opinions on the age of Srebrna Góra formation.

Opis:
Several sections record the relation between the “black flysch” and Upper Cretaceous red shales in the Grajcarek thrust-sheets. In all the sections studied the “black flysch” appears in the core of imbricated folds or thrust-sheets, whereas the limbs are composed of Upper Cretaceous deposits. The transitional beds between the “ black flysch” and the Upper Cretaceous red shales are composed of green and black bituminous shales, green and red radiolarites and cherty limestones. Biostratigraphical investigations have revealed a similar type and sequence of microfauna assemblages in all the sections studied and significant redeposition of Jurassic calcareous benthic foraminifera, calcareous nannoplankton, molluscs, sponge spicules and crinoid elements. The Cretaceous age (Aptian/Albian-?Cenomanian) of the “black flysch” is shown by the presence of agglutinated foraminifera and microfacies data. These deposits are underlain by a Kimmeridgian-Aptian radiolarite/limestone condensed succession and overlain by Turonian-Campanian hemipelagic red shales and Maastrichtian/Lower Paleocene conglomerates and thick-bedded silicilastic turbidites of the Jarmuta Formation. Such a sequence of deposits is typical of the Outer Carpathian basins and records the global Mid/Late Cretaceous phenomena in the world ocean, followed by the Cretaceous Oceanic Red Beds.

Opis:
Thenetwork of joints cutting the flysch deposits in the western Podhale is reasonably regular both in map scale and in individual outcrops. It is formed by five sets having a different orientation with respect to the range of the Podhale Synclinorium, as well as a different age and origin. The oldest diagonal sets (DR, DL) are conjugate and roughly coeval and were formed as "potential shear surfaces" in horizontal beds, whereas their further opening proceeded in an extensional mode. The younger sublongitudinal set (L') comprises extensional joints originated during the early buckling of beds. The transverse set (T), younger than the L'-set, comprises extensional joints formed in relation to the WNW-ESE extension of the Podhale Synclinorium. The youngest longitudinal set (L) originated in an extensional mode in consequence of stress relaxation in the rock massif during postorogenic uplift. Joint density increases in areas involved in relatively strong tectonic disturbances: the zone of tectonic contact between the flysch and the Pieniny Klippen Belt, the zone of contact between the Paleogene deposits, the Tatra Massif and the Biały Dunajec fault zone.

Opis:
The occurrence of mineral waters and related spas constitutes the leading theme of the projected geopark: Flysch Carpathians and their mineral waters. The geopark is located on the Beskid Sądecki and Beskid Niski area on the Polish side. It is situate in the area of the occurrence of three Carpathian units: Magura Nappe (the major part of the area), which includes Krynica, Bystrica, Racza and Siary tectonic-facies zones; Silesian Nappe and Grybów Unit. Besides mineral waters, the geodiversity of the area is defined by well exposed flysch rocks profiles including clastic type localities of the Magura Nappe described in the XIX century pioneers of geological investigations. The landslide morphology, attractive geomorphological forms like waterfalls, diversified river valleys, tors as well as places connected with history and tradition of exploration and exploitation of Carpathian hydrocarbons fields. The type localities of profiles of Grybów, Siary and Krynica Units as well as Łabowa Variegated Shales, Beloveza and Malcov formations. All these elements represent geotouristical attractions with high potential. They will be included in the network of preserved geosites within the projected geopark. The analysis of proposed geopark Flysch Carpathians and their mineral waters indicates high degree of diversification of natural values, especially geodiversity as well as richness of historical-cultural heritage. The preservation and protection methods are also diversified. This region represents unique geoenvironmental and historical values on the European scale, therefore providing good chances for establishment of geopark. The proposition of geopark with mineral waters and related spas in the Flysch Carpathians is first such project in the world. The documentation of geosites was already gathered during this stage of work, it requires only actualization, minor additions and construction of unified database. The evaluation of the actual touristic infrastructure provided also generally positive results, only the eastern part of geopark requires additional investments and promotion.

Obecnie około 90% mieszkańców pobiera wodę z systemu wodociągowego, jednak lokalne ujęcia wód podziemnych są nadal używane. Płytkie, nieizolowane wody podziemne są bardzo podatne na wpływy klimatyczne i antropogeniczne. Potwierdziły to analizy składu chemicznego wykonane w latach 1971- 2001. Najniższą jakość wody powierzchniowe i podziemne miały w latach 1980. W wyniku inwestycji środowiskowych ich jakość znacząco się poprawiła. W wodach podziemnych, wyraża się to wzrostem zawartości węglanów i generalnym zmniejszeniem zawartości siarczków i chlorków. Niepokojący jest stały wzrost zawartości azotanów, które jednak nie zagrażają głębszym wodom podziemnym, chronionym przez dobrze izolujące łupki fliszowe.

Opis:
Conventional and high-resolution analyses of heavy minerals from the gravity flow-deposited sandstones of the Campanian–Maastrichtian interval of the Ropianka (Upper Cretaceous–Paleocene) and Menilite (Oligocene) formations of the Polish Carpathians display similar compositions in terms of mineral species. Zircon, tourmaline, rutile, garnet, staurolite and kyanite belong to the main constituents in both formations. Apatite is common in the Ropianka Fm., while the Menilite Fm. almost lacks this mineral. Furthermore, individual hornblende grains were found in the Ropianka Fm., while andalusite is present only in the Menilite Fm. The Ropianka Fm. is relatively richer in zircon, tourmaline, garnet and apatite, while the Menilite Fm. contains more staurolite and kyanite. Zircon and tourmaline colour and morphological varieties are similar in both formations. The similarities of the heavy mineral assemblages studied suggest origin of these minerals from lithologically similar rocks. Negative correlations between the zircon + tourmaline + rutile (ZTR) values and the content of garnet and staurolite in the Ropianka Fm. may indicate, to a large extent, first-cycle delivery of garnet and staurolite to the formation. Negative, but low, correlation valid only for ZTR and garnet and positive correlations for ZTR and staurolite and kyanite in the Menilite Fm. suggest delivery of these minerals from sedimentary rocks or/and palimpsest sediments. The data obtained on mineral relationships and their morphology suggest mixed first-cycle and recycled provenance of the heavy minerals studied. Additionally, the first-cycle material input seems to be larger during the Ropianka Fm. sedimentation, while during the deposition of Menilite Fm. the contribution of material delivered from erosion of recycled sediments appears more prominent. The heavy mineral evidence suggests a change at the northern margin of the Skole Basin from an immature passive margin with a high relief during sedimentation of the Campanian–Maastrichtian part of the Ropianka Fm. to a mature passive margin with a low relief during sedimentation of the Menilite Fm.

Opis:
In the Polish sector of the Magura Nappe, along the front of the Pieniny Klippen Belt, strongly tectonized calcareous flysch up to 1000 m thick is exposed. Previously these deposits, composed of thin- to thick-bedded flysch, with a packet of Łącko-type marls, have been included into several Paleocene/Eocene formations, e.g., the Szczawnica Formation. This formation contains a poor assemblage of agglutinated foraminifera and a relatively rich assemblage of calcareous nannoplankton, with abundant reworked species. The youngest species give evidence of the NN2 Zone (Lower Miocene). Additionally, in three profiles (Szlachtowa, Knurów and Waksmund) of the Kremna Fm., Early Miocene foraminifera have been recognized. This research documented that during the Burdigalian, at the front of Central Western Carpathians, there still existed a residual marine basin probably up to 100 km wide. These deposits also contain thick packages of exotic carbonate conglomerates derived from the SE, previously regarded as the Jarmuta Formation.

Opis:
The "black flysch" deposits (Szlachtowa Formation at Podubocze near Czorsztyn in Poland), attributed so far to the Pieniny Klippen Basin successions, and at Hałuszowa in Poland as well as at Kamienka in Eastern Slovakia, attributed to the Grajcarek Succession of the Magura Basin, have yielded rich dinoflagellate cyst assemblages consisting of forms both redeposited (from Upper Triassic to Aalenian) and indigenous (Lower Bajocian to Upper Bajocian). An Early to Late Bajocian age of the deposits investigated is thus indicated, and this along with other stratigraphical, sedimentological and tectonic data indicates that all the deposits in question represent the early stages of development of the Magura Basin. The formation of “black flysch” deposits was possibly related to the Early Bajocian uplift of the Czorsztyn Ridge which resulted from the opening of the Magura Ocean. The occurrence of the deposits of the Magura Basin below the overthrusted deposits of the Klippen Basin (Czorsztyn Unit) in the area of study results in a marked change in the structural interpretation of the Pieniny Klippen Belt.
