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:
Middle and Upper Juras siclime stones from the Polish part of the Pieniny Klippen Belt (PKB) were palaeomagnetically studied at six localities. The Middle Jurassic redcrinoidal lime stones of the Krupianka Lime stone Formation and Oxfordian radiolarites of the Czajakowa Radiolarite Formation, sampled in the eastern part of the Polish section of the PKB, were ei ther unsuitable for palaeomagnetic studies (Krupianka Klippe) or remagnetized in the Neogene (Baba and Zaskalskie-Bodnarówka klippen). The Czorsztyn Lime stone Formation was investigated at the localities of Krempachy (up per Mid dle Jurassic: upper most Bajocian?-Callovian?), Obłazowa (mid dle Oxfordian) and Rogoźnik (Rogoża Coquina Member- Kimmeridgian). A pre-folding, mixed polarity component of magnetization was revealed, which was interpreted as primary. Palaeoinclinations differ slightly, but not significantly, between localities. The palaeolatitude of the Polish sector of the PKB, averaged for the Middle/Upper Jurassic, amounts to 22°N (± 5°). It corresponds to the estimated palaeolatitudes of the northern margins of the Adriatic microplate and indicates a significantly large distance from the European plate. There is a growing evidence for a northward drift of the PKB in the Late Jurassic up to the earliest Cretaceous: from the palaeolatitude of 22°N in the Late Jurassic up to 28°N in the western part, in Po land/W Slovakia, and from 28° up to 36°N in the eastern part of the PKB in Ukraine. Systematically lower palaeolatitudes in the west combined with exsting palaeogeographic and geotectonic scenarios would account for a NE-SW orientation of the Czorsztyn Ridge in the Late Juras sic/earliest Cretaceous.

Opis:
Fractured bedrock aquifers are becoming increasingly utilized in rapidly developing parts of the western USA, including the Emigration Canyon near Salt Lake City, Utah. The emigration Canyon area is located physiographically in the Wasatch Mountains (western province of the Rocky Mountains), and structurally within the Idaho–Utah–Wyoming thrust belt. The study area is characterized by a series of thrust faults and associated folds that transported a thick section of sedimentary rocks eastward to southeastward during the Cretaceous to Early Tertiary Sevier Orogeny. Locally developed cleavage, minor folds, and minor fault and fracture networks produce additional internal deformation. Stratigraphically, sedimentary rocks in the study area include steeply dipping Pennsylvanian to Early Cretaceous limestone, dolostone, sandstone, mudstone and shale, locally capped with gently dipping Late Cretaceous conglomerate. Shale and mudstone intervals are characterized by smaller-scale, bed-parallel partings, while thicker-bedded limestone, dolostone and sandstone units typically have larger-scale fractures of variable orientation. Sandstones and carbonate intervals have generally higher hydraulic conductivity, whereas shale and mudstones are primary confining layers. The water flow system is also strongly affected by local topography. Two major fractured aquifers are the Lower Jurassic Nugget aquifer and the Middle Jurassic Twin Creek aquifer. The Nugget aquifer consists of thick-bedded sandstone with prominent primary porosity and secondary fracture porosity. The Twin Creek aquifer consists mostly of thin-bedded limestone and shaley limestone, with mostly secondary fracture porosity. The aquifers are separated by a shale interval. Based on results of long-term pumping tests, long-term monitoring of water table elevation and variability of spring discharges, the aquifers react independently and differently to fluid stresses, indicating variable effects of primary grain porosity and secondary fracture porosity. The Twin Creek aquifer is characterized by significantly greater seasonal variations of hydraulic head, stronger effects of impermeable boundaries and anisotropy, and lower storage. Typical values of transmissivity are 10–100 m[sup]2[/sup]/day, for the Twin Creek and Nugget aquifers, but vary with changes in lithology and fracture characteristics.
Szczelinowe poziomy wodonośne są coraz częściej eksploatowane w intensywnie rozwijających się zachodnich regionach USA, w tym Emigration Canyon w okolicach Salt Lake City w stanie Utah. Pod względem fizjograficznym obszar badań zlokalizowany jest w górach Wasatch (zachodnia część Gór Skalistych), pod względem strukturalnym – w obrębie pasa płaszczowinowego Idaho–Utah–Wyoming. Obszar badań charakteryzuje się serią uskoków i fałdów płaszczowinowych zbudowanych z miąższych serii skał osadowych, które zostały przesunięte na wschód lub południowy wschód podczas kredowych i wczesnotrzeciorzędowych ruchów górotwórczych. Utwory płaszczowinowe uległy dodatkowym deformacjom tektonicznym w postaci lokalnych spękań, drugorzędnych fałdów i uskoków. Typowe serie osadowe to wapienie, dolomity, piaskowce, mułowce i iłowce deponowane od karbonu do kredy. Lokalnie przykryte są zlepieńcami późnokredowymi. Skały te charakteryzują się stromym upadem. W iłowcach i mułowcach występują lokalne, równoległe do kierunku warstwowania spękania, w skałach gruboławicowych (wapienie, dolomity, piaskowce) występują szczeliny o zmiennej orientacji.Piaskowce i skały węglanowe stanowią warstwę wodonośną, charakteryzują się wysokimi wartościami współczynnika filtracji, natomiast iłowce i mułowce to utwory słabo przepuszczalne i stanowią zazwyczaj warstwy napinające zwierciadło wody. Pompowania badawcze wykazały, że utwory słabo przepuszczalne mogą przewodzić wodę, aczkolwiek proces ten jest nieporównywalnie wolny w stosunku do przepływu w warstwach wodonośnych. System przepływu wód podziemnych jest również silnie uzależniony od morfologii terenu.Na badanym obszarze występują dwa poziomy wodonośne o charakterze szczelinowym: dolnojurajska formacja Nugget oraz środkowojurajska formacja Twin Creek, rozdzielone serią słabo przepuszczalnych iłowców. Formacja Nugget składa się głównie z gruboławicowych piaskowców charakteryzujących się wyraźną porowatością szczelinową i porową, formacja Twin Creek – z cienkoławicowych wapieni i wapieni marglistych charakteryzujących się porowatością szczelinową. Oba poziomy wodonośne wykazują cechy syngenetycznej porowatości międzziarnowej i postgenetycznej porowatości szczelinowej, co ujawnia się w odmiennych wynikach próbnych pompowań, wahaniach zwierciadła wód podziemnych i wydajności źródeł. Formacja Twin Creek charakteryzuje się wyraźnie większymi wahaniami sezonowymi zwierciadła wód podziemnych, silniejszymi wpływami granic nieprzepuszczalnych, anizotropowością i mniejszą pojemnością warstwy wodonośnej. Wartości przewodnictwa wodnego zawierają się w przedziale 10–100 m[sup]2[/sup]/dobę i są zazwyczaj niższe w formacji Twin Creek; zależą od litologii i charakterystyki szczelin.

Grajcarek Unit
Opis:
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 ferromanganese crusts (FMC) and nodules at Stankowa Skała near Nowy Targ (Pieniny Klippen Belt, Poland) are developed in pelagic condensed limestones. The crusts appear on an uneven surface of limestones with thinshelled Bositra bivalves dated to the (?)uppermost Bajocian -Callovian. The crusts are overlain by Oxfordian limestones rich in Globuligerina, containing Fe-Mn nodules and small fragments of calcite stromatolites rich in Mn, Fe, Ba oxyhydroxides. Petrological analyses of the FMC from Stankowa Skała indicate their hydrogenetic origin. Growth of the FMC was coeval with a period of a rapid oceanic floor spreading from the Bajocian to the Callovian, postulated for the Pieniny Klippen Belt in the Jurassic time on the basis of the palaeomagnetic studies.

Opis:
Occurrences of mafic alkaline volcanics are scattered all around Europe, being mostly related to anorogenic, extensional tectonic environments. While the widespread Cenozoic alkaline basalts have been intensively studied and are comparatively well-known, their Cretaceous precursors were often associated with the Alpine-Carpathian orogenic zones, and so their genesis and geodynamic setting are partially obscured by superimposed deformation and alteration. We describe a newly discovered body of melanephelionites inserted within the Upper Cretaceous deep-marine pelagic succession of the Pieniny Klippen Belt in Western Slovakia. The body consists of hyaloclastic lavas of nephelinitic composition. The mineralogical composition and geochemical features of the Vršatec volcanites correspond to melanephelinites. Reconstruction of the geodynamic setting of the Cretaceous mafic alkaline volcanism in the Alpine-Carpathian-Pannonian realm infers a general extensional/rifting tectonic regime that ultimately led to the opening of Penninic oceanic rift arms. However, this rifting started as basically passive and non-volcanic. Only during the later, post-breakup extension phases did the slow-spreading oceanic ridges develop, which are characterized by the MORB-type (mid-ocean-ridge basin) basaltic volcanism. Alkaline volcanic provinces have a linear character and appear to follow passive continental margins of Penninic oceanic arms opened during the Jurassic and Early Cretaceous. We infer that alkaline volcanism resulted from heating and partial melting of the subcontinental mantle lithosphere on the peripheries of asthenospheric upwellings confined to slow-spreading ridges of the Alpine Tethys. Consequently, regarding the debate about the plume vs. non-plume origin of the Cretaceous alkaline volcanism, the geological data from this area rather support the latter affinity.

Opis:
To characterize the deep structure of the Klippen Belt, we made magnetotelluric measurements in profiles across the western and eastern segments in the territory of Slovakia, from which we created 3D models. The models revealed significant differences in tectonic structure between these segments. In the western segment, the Klippen Belt is located in the southern reversing wing of the original subduction flower structure (retroarc thrusting) with an overthrust to the south onto the Inner Western Carpathian units. This structure was later modified by significant transpressional movements. In the eastern segment, the Klippen Belt is primarily an organic part of the accretionary wedge of the Outer Western Carpathians and it is overthrusted onto the Flysch Belt. This was followed by modification of the structures, mostly in a transpressional regime, including local reversing overthrusts and the development of a steep fault boundary, mainly along the southern margin, against the Inner Carpathian Paleogene succession. These differences between the structure of the western and eastern Klippen Belt segments indicate the contrast between the interaction of the western and eastern parts of the Inner Western Carpathians with the European Platform. In the western part, oblique collision and sinistral transpression dominate. In the eastern part, by contrast, subduction and orthogonal collision dominated over later transpressional modifications.

Opis:
The western frame-margin of the Upper Silesian Coal Basin provides good case studies for structural evolution of the fold-and-thrust belt. This study is concerned with tectonic junctions taking place on the Late Variscan front of the Moravosilesian Fold Zone and coal basin. Clues of evolution of fold-and-thrust belt were reconstructed on the base of six cross-sections and using balancing procedure to calculate the shortening. These structural cross-sections illustrated the two principal positive and negative inversion processes of Upper Silesian Coal Basin. The fold shortening varies in range of 25 up to 30% and in low range of 4 up to 18%. The thrust shortening is contrary to fold shortening and changed range of about 10% up to 50%. In the central part of fold-and-thrust belt summarised shortening is 55%, which gradually decreases northward up to 35% and southward up to 30%.

Opis:
New geological, geochemical and U-Pb SHRIMP zircon age data brought more information about basement units in subsurface of Southern Poland and SE Romania, which allows to revise and refine some earlier models in the framework of the break-up of the Rodinia/Pannotia supercontinent. In the Brno Block, Moravia, and in the Upper Silesia Block, three different terranes formed the composite Brunovistulia Terrane. The Thaya Terrane (low eNd(T)) of Gondwana (Amazonia) descent collided obliquely at 640–620 Ma with the Slavkov Terrane (moderate eNd(T)) composed of amphibolite facies metasediments and arc-related, mostly unfoliated granitoids which intruded at 580–560 Ma. At that time, back-arc rifting separated the couple Thaya–Slavkov (inherited zircons: 1.01–1.2, 1.4–1.5, 1.65–1.8 Ga) that drifted away from Gondwana until collision around 560–550 Ma with the Rzeszotary Terrane, the Palaeoproterozoic (2.7–2.0 Ga) crustal sliver derived from Amazonia or West Africa. At least these three units composed Brunovistulia, which occurred at low latitudes in proximity to Baltica as shown by palaeomagnetic and palaeobiogeographic data. Then Brunovistulia was accreted to the thinned passive margin of Baltica around its Małopolska promontory/proximal terrane. A complex foreland flysch basin developed in front of the Slavkov–Rzeszotary suture and across the Rzeszotary–Baltica/Małopolska border. The further from the suture the less amount of the 640–550 Ma detrital zircons extracted from the Thaya–Slavkov hinterland and the smaller eNd(T) values. In West Małopolska, the flysch contains mainly Neoproterozoic zircons (720–550 Ma), whereas in East Małopolska 1.8–2.1 Ga and 2.5 Ga zircons dominate, which resembles nearby Baltica. The basin infill was multiphase folded and sheared; in Up per Silesia prior to deposition of the pre-Holmia Cambrian over step. In Małopolska, the folded flysch series formed a large-scale antiformal stack with thermal anticline in its core marked by low-grade metamorphic overprint. In Central Dobrogea, Moesia, Ediacaran flysch also contains mainly 700–575 Ma detrital zircons which link the source area, likely in South Dobrogea with ca. 560 Ma granitoids, rather close with Gondwana. However, fauna in Lower Cambrian overstep strata shows Baltican affinity. Such features resemble Upper Silesia, thus Brunovistulia might have extended beneath the Carpathians down to Moesia. The other part of South Dobrogea with Palaeoproterozoic ironstones resembles Ukrainian banded iron formation. If true, the Baltican sliver would be incorporated in Moesia. Such a possibility concurs with the provenance data from Ediacaran flysch of Central Dobrogea, which points to uplifted continental block as a source of derital material. Our study supports an earlier proposition that at the end of the Neoproterozoic a group of small terranes that included Brunovistulia, Moesia and Małopolska formed the Teisseyre-Tornquist Terrane As semblage (TTA). In our model, a characterisistic feature of the TTA was a mixture of crustal elements that were derived from both Gondwana and Baltica, which gave rise to mutual collisions of the elements prior to and concurrent with the docking to Baltica in latest Ediacaran times. The presence of extensive younger covers and complex Phanerozoic evolution of individual members of the TTA impede the recognition of their Neoproterozoic history.

The hydrogeological regime of sources can help in the recognition of regional hydrogeological conditions of this lithological-structural unit, as they exemplify groundwaters on the surface in a natural state. Long-term stationary observations, have enabled characterisation of water flow rates and chemistry for nine springs, representative of various parts of the Pieniny Klippen Belt. These analyses demonstrate a seasonal variability. The value of the boundary discharge is similar in all analysed springs and reaches values of 4 to 6 dm3/min.

Opis:
The geological position and geochemistry of the basaltic sill and tuffs occurring within the Berriasian–?Albian pelagic limestones of the Czorsztyn Succession are described. The volcanic rock succession of the Velykyi (= Veliky) Kamenets’/Vilkhivchyk (= Vulkhovchik, Vulhovchik, Olkhivchyk) sites is related to intra-plate submarine volcanism, which took place at the southeastern termination of the Pieniny Klippen Belt. This volcanism was probably associated with the Early Cretaceous opening of the Magura/Fore-Magura basinal system, bounded by the Silesian/Marmarosh and Czorsztyn palaeoridges to the north and south respectively. The alkaline volcanic rocks from the Velykyi Kamenets’/Vilkhivchyk sites are geochemically similary to the basaltic block from Biała Woda (Małe Pieniny Mts., Poland), which is an olistolith a few metres across within the Jarmuta conglomerates (Maastrichtian/Paleocene). This basaltic block was eroded from the frontal part of the Czorsztyn Nappe and was deposited in the uppermost part of the Grajcarek Succession at the southeastern margin of the Magura Basin.

This paper provides the results of a new litho- and biostratigraphic study from the contact zone between the Magura Nappe and Pieniny Klippen Belt close to Polish-Slovakian border. 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.

For this purpose, dinoflagellate cysts have been studied from a set of samples collected from the Szlachtowa, Opaleniec, Pieniny Limestone, Kapuśnica and Wronine formations exposed at that site (additional sample from the Pieniny Limestone Formation was studied). The Szlachtowa Formation, a very characteristic lithostratigraphic unit, which consists of black shale and sandstones extremely rich in mica flakes, occasionally referred to literature as the so-called "black flysch", yielded rich and well-preserved assemblages. Their age is Middle Jurassic, spanning the Aalenian to Lower Bajocian. The exposures of the Szlachtowa Formation at Szczawnica-Zabaniszcze are located close to the outcrops of the Opaleniec Formation. The calcareous spotted shale from this lithostratigraphic unit yielded rich dinoflagellate cyst assemblage characteristic for Late Bathonian (Early Callovian). The Opaleniec Formation tectonically contacts with very similar non-calcareous spotted shale of the Wronine Formation. Its age, based on infrequent dinoflagellate cysts is Aptian–Albian. Similar, Lower Aptian age was concluded for the Kapuśnica Formation. Late Barremian–earliest Aptian dinoflagellate cysts have been found in the underlying topmost part of the Pieniny Limestone Formation.

Opis:
An isolated limestone hill (Cisowa Skała), located in the Podhale Basin in southern Poland, has yielded mollusc shells and small vertebrate bones in deposits filling small karst forms such as rock shelters, characteristic molluscan assemblages can be identified, the succession of which reflects changes in the environment and also microhabitat variations depending on local factors, such as slope exposure and type of vegetation. These local factors markedly affect regional environmental trends determined primarily by climate change and, during the last several hundred years, also by human activity. Such malacological analysis enables effective palaeogeographical reconstructions, both on the scale of geographical regions and for microhabitats.

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.
