    Opis:
    Structural analysis of the Miocene deposits of the northern marginal part of the Carpathian Foredeep, from the Nida Trough in the west to Tarnobrzeg in the east shows that three tectonic phases affected Neogene deposits of the Carpathian Foredeep: (1) an Early Styrian phase - Early Badenian synsedimentary movements, (2) a Moldavian phase (Late-Styrian) - Early/Late Badenian, after deposition of gypsum and during deposition of the lower part of the Pecten Beds, (3) an Attican phase - Sarmatian-Pliocene(?), after deposition of the Krakowiec Beds. The two Badenian phases involved reactivation of NW-SE basement faults Early-Styrian phase activity along these faults resulted in facies changes and thickness variability in the Baranów Beds. Reactivation of these faults during the Moldavian phase resulted in a considerable increase of their throws. Strata in the footwalls of faults were antithetically rotated to form structural traps for subsequent hydrocarbon and sulphur deposits. During the Attican phase, a horizontal compression stress field (compression direction - 30-50°) produced transverse and oblique faults (NE-SW and ENE-WSW) with strike-slip and oblique-slip movements. These faults were responsible for "pumping" hydrocarbons into the earlier formed traps. Minor deformations within gypsum deposits and seismotectonic features of the Witów Gravels are also discussed.

    Opis:
    The paper presents the results of geological mapping and a detailed structural analysis carried out in the Łączna Anticline. This elevated region coincides with the Zawory (Cz. Závora) mountain range in the Central Sudetes (SW Poland). The Łączna Anticline separates two minor geological units (depressions) within the northwestern part of the Intrasudetic Synclinorium – the Krzeszów and the Police brachysynclines. In numerous exposures of Triassic and Upper Cretaceous sedimentary rocks, several brittle and a few soft-sediment deformation structures have been recognized. Their orientation and spatial distribution suggest that the Łączna Anticline is a horst-like, intra-basinal high, formed due to permanent extension, dextral strike-slip movements within fault zones, and negative flower structures. The studies did not confirm the occurrence of continuous deformations such as anticlinal bends and flexures. The results show that the preservation of some lithological varieties of sedimentary rocks within modern morphological and structural elevations reflects the migration of centres of maximum subsidence within a pull-apart basin system. A new structural and geodynamic interpretation for the Łączna Anticline area is proposed.

    Orava-Nowy Targ Basin
    Opis:
    The Neogene sedimentary succession of the Orava-Nowy Targ Basin directly overlies the Central Carpathian Paleogene Basin deposits, the Magura Unit, and the Pieniny Klippen Belt. It provides an excellent geological record that postdates the main Mesoalpine structural and geomorphological processes in the Western Carpathians. Sedimentological, petrographical and geochronological investigations have allowed forthe re-examination of pyroclastic material, zircon dating, and a discussion on the relation of the Orava-Nowy Targ Basin to the exhumation of the Tatra Massif. The Bystry Stream succession is composed of NNW-inclined freshwater siltstones, sandstones and conglomerates. A few small, sometimes discontinuous, light grey intercalations of pyroclastic deposits and a single 1-2 m thick tuffite layer occur in the upper part of the succession. The tuffite contains an admixture of organic matter and siliciclastic grains (e.g., mica), suggesting that the volcanic ash fall was accompanied by normal deposition from weak currents. Sedimentation of deposits of the Bystry Stream succession took place in terrestrial settings, predominantly on floodplains and in rivers, in the vicinity of a hilly area supplying the basin with eroded material. The age of the tuffite layer from the Bystry Stream succession was determined at 11.87 +0.12/-0.24 Ma. The source of volcanogenic material in the tuffite was probably volcanic activity in the Inner Carpathians-Pannonian region, where effusive and volcanoclastic sillca-rich rocks were being produced by extrusive and explosive activity ~12 Ma. Obtained result connects the development of the Orava-Nowy Targ Basin at ~12 Ma with the late stage of the main episode of the Tatra Massif exhumation between ~22-10 Ma.

    Opis:
    The aim of this study was to reconstruct the location mechanism of a Triassic sandstone wedge within folded Palaeozoic rocks. A vertically oriented Buntsandstein succession (Lower Triassic) from Józefka Quarry (Holy Cross Mountains, central Poland), steeply wedged within folded Devonian carbonates, is recognised as an effect of normal faulting within a releasing stepover. The sandstone succession, corresponding to the Zagnańsk Formation in the local lithostratigraphic scheme, is represented by two complexes, interpreted as deposits of a sand-dominated alluvial plain (older complex), and coarse-grained sands and gravels of a braided river system (younger complex). The sandstone complex was primarily formed as the lowermost part of the several kilometres thick Mesozoic cover of the Holy Cross Mountains Fold Belt (HCFB), later eroded as a result of the Late Cretaceous/Paleogene uplift of the area. Tectonic analysis of the present-day position of the deformed sandstone succession shows that it is fault-bounded by a system of strike-slip and normal faults, which we interpret as a releasing stepover. Accordingly, the formation of the stepover in the central part of the late Palaeozoic HCFB is evidence of a significant role of strike-slip faulting within this tectonic unit during Late Cretaceous/Paleogene times. The faulting was probably triggered by reactivation of the terminal Palaeozoic strike-slip fault pattern along the western border of the Teisseyre–Tornquist Zone.

    Grójec fault zone
    Opis:
    Interpreted seismic data located within the Grójec fault zone confumed that this zone could be regarded as a strike-slip fault zone, perpendicular to the main axis of the Mid-Polish Trough. Role of this fault zone during Permian-Early Cretaceous subsidence of the Mid-Polish Trough was minimal, and could have been related to tensional/transtensional reactivation of deep structures related to the NW edge of the Małopolska gravity high. In latest Cretaceous - early Paleogene, due to on-going inversion of the Mid-Polish Trough (in transpressional regime) and successive uplift of the Mid-Polish Swell, Grójec fault zone was reactivated. This process could be however most probably regarded as secondary to inversion tectonics and associated strike-slip movements along the NE edge of the Trough/Swell. Inversion of the 4 segment of the Mid-Polish Trough took place in Turonian? -Coniacian-Maastrichtian- early Paleogene.

    Opis:
    The structure and evolution of the Polish part of the Sudetes is reviewed on the basis of published data and interpretations. The Sudetic segment of the Variscides and its adjacent areas were subjected to multi-stage accretion during successive collisional events that followed closure of different segments of the Rheic Ocean. Early Variscan deformations culminated in the Late Devonian due to docking of the Armorican terrane assemblage to the southern margin of Laurussia. The Variscan orogenic activity continued into the Carboniferous and was associated with a new collision and intense folding and thrusting, followed by abundant magmatism, gravitational collapse and resulting exhumation of deeply buried metamorphic complexes as well as by inversion of the foreland basin. In the Sudetes, Variscan tectonostratigraphic units are tectonically juxtaposed and often bear record of contrasting exhumation/cooling paths, constrained by palaeontological and geochronological data. This provides evidence for the presence of allochthonous units, of partly cryptic tectonic sutures and an of overall collage-type tectonics of that area. The main lithostratigraphical components distinguished within the Sudetes are: 1) non-metamorphic to metamorphosed Neoproterozoic igneous suites accompanied by volcano-sedimentary successions, 2) Late Cambrian granitoids gneissified during the Variscan orogeny, 3) variously metamorphosed Ordovician through Devonian volcano-sedimentary successions deposited in pre-orogenic extensional basins, 4) dismembered fragments of a Late Silurian ophiolitic complex, 5) Devonian to Lower Carboniferous sedimentary successions of a passive continental margin, 6) Carboniferous granitoids, and 7) clastic sediments of Devonian and/or Early Carboniferous intramontane basins. All these components are assembled to form part of the internal Variscan orogenic zone largely exposed within the area of the Bohemian Massif. A three-partite subdivision of the Sudetes proposed here reflects different timing of deformation and exhumation of the respective segments. The Central, West and East Sudetes were deformed and amalgamated during the Middle/Late Devonian, at the turn of the Devonian and Carboniferous and during Early Carboniferous, respectively. Problems in extending the classical tectonostratigraphic zonation of the Variscides into the Sudetes are explained as due to activity of Late Palaeozoic strike-slip faults and shear zones, disrupting and dispersing the initially more simply distributed tectonostratigraphic units into the present-day structural mosaic.

    Opis:
    A newly recognized Mnin restraining stepover is identified in the Permo-Mesozoic cover of the western part of the Late Palaeozoic Holy Cross Mountains Fold Belt (Poland), within a fault pattern consisting of dextral strikeslip faults. The formation of a large contractional structure at the Late Cretaceous – Cenozoic transition displays the significant role of strike-slip faulting along the western border of the Teisseyre-Tornquist Zone, in the foreland of the Polish part of the Carpathian Orogen. Theoretical relationships between the maximum fault offsets/ mean step length, as well as between the maximum fault offsets/mean step width allowed the estimation of the values of possible offsets along the Snochowice and Mieczyn faults forming the Mnin stepover. The estimated values suggest displacements of as much as several tens of kilometres. The observed offset along the Tokarnia Fault and theoretical calculations suggest that the strike-slip faults west of the Late Palaeozoic Holy Cross Mountains Fold Belt belong to a large strike-slip fault system. We postulate that the observed significant refraction of the faults forming the anastomosing fault pattern is related also to the interaction of the NW-SE-striking faults formed along the western border of the Teisseyre-Tornquist Zone and the reactivated WNW-ESE-striking faults belonging to the fault systems of the northern margin of the Tethys Ocean.

    Opis:
    The paper focuses on the analysis of small-scale strike-slip faults and second-order fractures in flat-lying Cieszyn Limestones of a quarry in Leszna Górna. In the western part of the Polish segment of the Outer Carpathians, the Silesian Nappe consists of two tectonic units: Cieszyn Unit and Godula Unit. The study area is located within the Cieszyn Unit. Several different kinds of tectonic structures have been distinguished, including mesoscale strike-slip faults, en echelon arrays, tip structures and linking structures. The investigations, including geometric and genetic analysis of strike-slip faults and fractures, have enabled reconstruction of structural evolution stages. Two evolutionary models are proposed in terms of the geometries of damage zones for small displacement strike-slip fault zones.

    Opis:
    Based on drillings, a number of geological cross-sections, and structure contour and isopach maps were composed to describe/analyse the structure and development of the Valmiera-Lokno Uplift (VLU), a basement block elevated up to 700 m with a heavily deformed and eroded platform cover in the East European Craton interior, along the regional Liepaja-Riga-Pskov Fault Zone (LRPFZ). Five isolated basement-cored anticlines (BCA), the Lokno, Haanja, Mõniste, Valmiera and Smiltene uplifts, arise in the platform cover on the VLU, whereas the downthrown LRPFZ side defines a complex monoclinal fold. The anticlines, straddling or occurring near the monocline, merge with it and thus have highly asymmetrical shapes. Thickness changes of stratigraphic units across the VLU reveal its complex history, reflecting regional tectonic activation pulses that varied noticeably even between neighbouring BCAs. In all, the latest Precambrian-earliest Ordovician initiation epoch of the VLU was followed by modest tectonic activity or a standstill period in the Middle Ordovician-Early Silurian. Intensifying tectonic movements culminated again in the prime of the Caledonian Orogeny in latest Silurian-earliest Devonian time, and faded thereafter towards the end of Early Devonian. The VLU has been reactivated occasionally since the latest Devonian and emerges as a crustal weakness in the recent movement and seismicity patterns. To decipher the origin of the VLU, hitherto factually undiscussed topics, a more detailed study of the LRPFZ, analysis of its fault pattern and kinematics alongside the regional tectonic setting/history is needed. A cursory look hints to a substantial Early Paleozoic sinistral strike-slip along the LRPFZ, allowing interpreting the VLU as a possible restraining bend structure.

    Opis:
    The Miocene Carpathian Foredeep Basin in Poland (CFB) developed in front of the Outer Carpathian fold-and-thrust belt, at the junction of the East European craton and the Palaeozoic platform. Within the upper Badenian through Sarmatian deposits of its eastern part, the CFB hosts numerous gas fields. The gas-bearing Miocene succession is characterised by a shallowing-upward trend of sedimentation and consists of offshore hemipelagic, turbiditic and deltaic and nearshore-to-estuarine facies associa-tions. The foredeep basin formation was largely controlled by the structure of its Neoproterozoic–Early Cambrian basement, especially by NW–SE trending faults inherited from Mesozoic tectonic history of SE Poland (subsidence and inversion of the Mid-Polish Trough). Several NW–SE-elongated, narrow basement pop-up structures developed in the northeasternmost part of the CFB, one of them being the Ryszkowa Wola block. The uplift of the pop-up basement block involved Miocene reactivation of older fault zones and resulted in the formation of a narrow, NW–SE elongated Ryszkowa Wola horst (RWH) above it, within the Miocene strata. A complex system of right-stepping, en-echelon, mainly normal faults of predominantly E–W trend, branching off from the NW–SE-striking boundaries of the RWH, has developed around and above the horst, leading to compartmentalisation of the Miocene succession into numerous, mutually displaced and rotated fault blocks. Such an association of deformation structures recognised from the 3D seismics was interpreted in terms of transpressive conditions with the horizontal maximum tectonic compression axis directed š E–W and a sinistral strike-slip displacements on NW–SE striking faults in the basement. The structural interpretation of the Ryszkowa Wola structure proposed here is in line with published results of analogue modelling of fault patterns in sediments overlying active strike-slip discontinuities in a rigid basement. The basement-cover interaction within the Ryszkowa Wola structure in the area of Sieniawa–Rudka was partly coeval with the Miocene deposition of the CFB infill. The uplift and horizontal displacements of the Ryszkowa Wola basement block modified the local subsidence pattern and the organisation of Miocene depositional systems. The syn-depositional strike-slip fault activity in the basement of the CFB resulted in differential movements and rotations of kinematically linked fault-blocks in the Miocene succession around and above the RWH, leading to the formation of numerous gas traps.

    Opis:
    Tectonic deformation structures (folds, strike-slip, reverse and normal faults as well as joints) are reported here from the topmost part of the youngest, clayey sediments of the Carpathian foreland basin (Krakowiec clays, Sarmatian, Miocene), in a clay pit located at a village ofWylewa near Sieniawa. Our structural study has revealed several joint sets, accompanying products of intense folding and faulting, and defining a structural pattern that can be easily interpreted in terms of structures formed in a transpressive regime above strike-slip faults in the basement. The origin of these structures is ascribed to tectonic activity of the NW-SE-trending Ryszkowa Wola horst known to occur directly beneath the Wylewa clay pit, at a depth of c. 500 to 1300 m and to involve the basement and the lower part of theMiocene succession. The structural pattern in question most likely reflects a sinistral strike-slip displacement on sub-vertical boundary faults of the lowermost part of the horst. Undisputable effects of this strike-slip motion have been recently documented by other authors using 3D seismic data. The deformation structures at Wylewa must have resulted from a young, late to post-Sarmatian tectonic activity in the basement of the Carpathian foreland basin, probably reflecting an E-W to ENE-WSW directed regional shortening episode.

    Opis:
    The damage zones of exhumed strike-slip faults dissecting Jurassic carbonates in the south-western part of the Late Palaeozoic Holy Cross Mountains Fold Belt reveal second-order faults and fractures infilled with syntectonic calcite. The subsequent development of a structural pattern of microscopic fault-related structures and calcite infillings reflects the activity of strike-slip faults that began in the Late Cretaceous (Late Maastrichtian) and lasted until the early Miocene (Langhian). The fabric of the syntectonic veins provides insights into the evolution of the permeable fault-related structures that were the main pathways for fluid flow during fault activity. Microstructural study of calcite veins coupled with stable isotope and fluid inclusion data indicates that calcite precipitated primarily in a rock-buffered system related to strike-slip fault movement, and secondarily in a partly open system related to the local activity of the releasing Chmielnik stepover or the uplift of the area. The presence of meteoric fluids descending from the surface into damage zones suggest that the strike-slip faulting might have taken place in a nonmarine, continental environment.

    Opis:
    Analizy tektoniczne wykonane na podstawie pomiarów powierzchni nieciągłości tektonicznych w obrębie masywów skalnych polskiej części Roztocza, pozwoliły na odtworzenie historii tektonicznej jego struktury, związanej z tworzeniem się zapadliska przedkarpackiego i etapami nasuwczymi Karpat. Analizy wykazały, że struktura Roztocza powstała w efekcie nakładania się asocjacji struktur tektonicznych związanych z formowaniem uskoku prawoprzesuwczego (tzw. struktury kwiatowe ‒ flower structures i struktury typu koński ogon – horse tail structure) i struktury forebulge związanej z wypiętrzeniem przedgórskim spowodowanym nasuwaniem się Karpat na przedpole (tu: zapadlisko przedkarpackie). Wielokrotne reaktywowanie stref dyslokacyjnych, obramowujących Roztocze i dzielących je na bloki, było efektem formowania się uskoków inwersyjnych (związanych ze strukturą forebulge), reaktywowanych później wskutek kolapsu jako uskoki normalne. Zmiana zwrotu uskoku przesuwczego ograniczającego Roztocze na sinistralny, była efektem reorientacji pola naprężeń spowodowanej zmianą kierunku nasuwczego Karpat ku SSE. Spowodowało to inwersję stref naprzemiennie obniżanych i wynoszonych wzdłuż krawędzi Roztocza: obecnie wynoszone są obszary z niezerodowanymi, miąższami pokrywami utworów neogeńskich, obniżane zaś fragmenty strefy krawędziowej erozyjnie pozbawione tych utworów. Współcześnie obserwowane dźwiganie neotektoniczne Roztocza jest efektem footwall elevation, związanej z zespołami aktywnych uskoków zrzutowych (normalnych), ograniczających strukturę zrębową Roztocza, jak też dzielących wał na bloki.
    The paper presents new concept of the tectonic development of the Roztocze region, uplifted as a tectonic horst structure. Measurements of tectonic discontinuities (joints, faults) in the rocks building the Roztocze region, as well as the analysis of Neogene deposits distribution on the Roztocze horst, have allowed authors to establish several tectonic stages of the Roztocze development. Thrusting of the Carpathians to the north caused the formation of a strike-slip (dextral) fault along the eastern part of their foredeep (and associated flower structures and horse tail structures). As a result of forebulge structure formation, caused by progressive thrusting of the Carpathian orogen and isostatic uplift of their foreland, strike-slip faults were reactivated as reverse-slip faults. Subsequently, due to collapse of the Carpathian massifs, discontinuities were again reactivated as dip-slip faults. The footwall elevation associated with normal faults formed into the Roztocze Horst and divided region to blocks, causing a neotectonic uplift of the Roztocze region.

    Opis:
    The Carpathian Orava Basin is a tectonic structure filled with Neogene and Quaternary deposits superimposed on the collision zone between the ALCAPA and European plates. Tectonic features of the south-eastern margin of the Orava Basin and the adjoining part of the fore-arc Central Carpathian Palaeogene Basin were studied. Field observations of mesoscopic structures, analyses of digital elevation models and geological maps, supplemented with electrical resistivity tomography surveys were performed. Particular attention was paid to joint network analysis. The NE-SW-trending Krowiarki and Hruštinka-Biela Orava sinistral fault zones were recognized as key tectonic features that influenced the Orava Basin development. They constitute the north-eastern part of a larger Mur-Mürz-Žilina fault system that separates the Western Carpathians from the Eastern Alps. The interaction of these sinistral fault zones with the older tectonic structures of the collision zone caused the initiation and further development of the Orava Basin as a strike-slip-related basin. The Krowiarki Fault Zone subdivides areas with a different deformation pattern within the sediments of the Central Carpathian Palaeogene Basin and was active at least from the time of cessation of its sedimentation in the early Miocene. Comparison of structural data with the recent tectonic stress field, earthquake focal mechanisms and GPS measurements allows us to conclude that the Krowiarki Fault Zone shows a stable general pattern of tectonic activity for more than the last 20 myr and is presently still active.
