Mid-Polish Trough
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 Mid-Polish Trough formed the axial part of the Polish Basin belonging to a system of the Permian-Mesozoic epicontinental basins of Western and Central Europe. It was filled by several kilometres of siliciclastics and carbonates, including thick Zechstein (approximately Upper Permian) evaporites. TheMid-Polish Trough was inverted in the Late Cretaceous-Paleocene times, when it was strongly uplifted and eroded. The presence of thick salt significantly influenced Triassic evolution of the central (Kuiavian) part of theMid-Polish Trough where the Kłodawa salt structure is located. Analysis of seismic data calibrated by several deep wells point to three main stages of the Triassic evolution of this structure. During Early andMiddle Triassic Kłodawa salt pillow grew above the basement extensional fault zone, during early Late Triassic (approx. time of deposition of the Lower Gypsum Beds) Kłodawa salt structure reached diapiric stage and salt eventually extruded on to the basin floor. Last stage was characterised by rather uniform sedimentation and lack ofmajor saltmovements. Wojszyce salt pillow located north-east of the Kłodawa salt structure grew until the Late Triassic (approx. time of deposition of the Upper Gypsum Beds) when basement fault zone located below it was probably inverted. This inversion triggered formation of the salt-cored Wojszyce Anticline and was followed by localised erosion and rather uniform Norian–Rhaetian (Lower Kłodawa Beds) sedimentation above the anticline. Local tectonic activity below the anticline might have additionally enhanced growth of the Kłodawa salt diapir. The presented tectono-sedimentary model of the relationship between basement and salt tectonics and their influence on the Triassic depositional systems is compatible with results of analogue modelling of linked basement-salt tectonics, and with a model based on mesostructural studies completed for the Kłodawa salt mine.

Opis:
Seven high-quality reflection-seismic lines, calibrated by wells, were interpreted in an effort to assess the timing of inversion and the structural configuration of the Pomeranian and Kuiavian segments of theMid-Polish Trough. Seismostratigraphic analyses of the Upper Cretaceous successions imaged by these seismic lines in the NE and SW marginal troughs of the Mid-Polish Swell document important along-strike stratigraphic and structural changes. Thickness variations of the Upper Cretaceous series, combined with the development of erosional unconformities and associated tectonic deformations indicate that inversion movements commenced during the late Turonian and intermittently persisted into the Maastrichtian and Paleocene. Earliest inversion movements were focused on the margins of the Mid-Polish Trough where Mesozoic sequences are decoupled from the sub-Zechstein series by Zechstein salts. Whereas the NE margin of theMid-Polish Trough is devoid of compressionally reactivated salt structures, its SWmargin is characterized by strong inversion- related salt tectonics. Progressive inversion of the axial parts of the Mid-Polish Trough was accompanied by uplift of its pre-Zechstein floor to and above the level of flanking, non-inverted areas, and by deep truncation ofMesozoic series across the culmination of the evolving Mid-Polish Swell. Inversion movements ceased towards the end of the Paleocene, as evidenced by the burial of the Mid-Polish Swell beneath essentially flat lying Eocene and younger series. Turonian-Paleocene inversion of the Mid-Polish Trough is coeval with the inversion of the Bohemian Massif, the North German Basin and the Sorgenfrei-Tornquist Zone. Inversion of the Mid-Polish Trough is considered to have been controlled mainly by compressional intraplate stresses that built up in the Carpathian foreland during the collision of the Inner Carpathian orogenic wedge with the European passivemargin, attesting to their increasing mechanical coupling, commencing during the Turonian. These stresses relaxed, however, with the end-Paleocene onset of imbrication of the Outer Carpathian domain, reflecting decoupling of the Carpathian orogenic wedge from its foreland.

Opis:
Main geodynamic and tectonic mechanisms responsible for evolution of foreland basins and their sedimentary infill are discussed. They include flexure of the lower lithospheric plate and its extension, growth of the orogenic wedge and sedimentation / erosion within the foreland basin. Recently formulated models of foreland basin system include four major depositional zones that are characterised by various tectono-sedimentary processes. Of particular importance for evolution of foreland basins is very complex interplay of tectonics and sedimentation, and significant lateral shift of tectonic and depositional zones. Evolution of frontal part of the orogenic wedge could be deciphered using growth strata i.e. depositional sequences formed in vicinity of growing thrust-related structures. Certain aspects of Miocene (Late Badenian–Sarmatian) evolution of the Polish Carpathian foredeep basin are discussed in a context of presented models of foreland basins.

Opis:
Permo-Mesozoic Mid-Polish Trough formed eastern segment of the Southern Permian Basin, within which thick series of the Upper Permian (Zechstein) evaporites, including rock salt, have been deposited. During subsidence phase the presence of thick salt series led to regional decoupling between sub-salt basement and supra salt Mesozoic sedimentary cover, and to development of various salt structures. Evolution of salt pillows and diapirs was genetically related to activity of the basement fault zones. The Goleniów, Dzwonowo-Człopa, Damasławek, Mogilno, Kłodawa and Lubień salt diapirs have been analyzed using conventional seismic reflection data acquired during petroleum exploration, and - in case of Damasławek and Lubień diapirs - shallow high-resolution seismic data. Interpretation of available seismic data gave new insight into geometry of these salt structures, finally shaped during Late Cretaceous-Palaeogene inversion of the Mid-Polish Trough and partly modified during younger (Neogene- Quaternary) phases of their tectonic activity.

Opis:
Based on reflection seismic data, a regional tectonicmodel was constructed for the sub-Zechstein basement of the Pomeranian (NW) segment of theMid-Polish Trough (MPT). This model is based on the concept that the thick Zechstein salts acted on a basin-wide scale as a mechanical decoupling layer during the Mesozoic evolution of the MPT. Due to this regional decoupling effect, Mesozoic extensional faulting was mostly restricted to the sub-Zechstein salt basement whilst normal faulting played a subordinate role in the Mesozoic syn-extensional sedimentary series characterized by gradual lateral thickness changes. Locally, normal faulting affecting Mesozoic series triggered the development of salt diapirs. Mechanical decoupling ofMesozoic series fromtheir pre-Zechstein substratum played also an important role during the Late Cretaceous-Paleogene inversion of the Mid-Polish Trough. Taking into account: 1— the location of Mesozoic thickness gradients, 2—the structural configuration of the sub-Zechstein basement, and 3—the location of salt structures, a tectonic map was constructed showing the inferred sub-salt fault zones that were active during the subsidence and inversion of the Pomeranian part of the MPT. A high degree of correlation was achieved between the seismically mapped regional sub-salt structural patterns and magnetic and gravity features, as well as the main inversion structures. Moreover, a very good correlation was established between the inferred basement fault zones and the gross thickness patterns of the Triassic-Jurassic successions. The NE boundary of theMPT was generally controlled by the SW margin of the East European Craton, whilst its SW boundary coincides with a system of fault zones most probably inherited from earlier tectonic phases. Contrary to previous hypotheses, there is no evidence for important strike-slip faulting transverse to the main axis of the Pomeranian segment of the MPT.

Opis:
Interpretation of seismic data from the Pomeranian segment of the Mid-Polish Trough (MPT) shows that this part of the MPT evolved in Mesozoic times as a decoupled sedimentary basin. Regional-scale decoupling was caused by the thick Zechstein salt layer. Detailed tectonic and seismostratigraphic analysis of seismic data from the vicinity of the Oświno IG 1 well allowed for significant reinterpretation of the Oświno structure, which was previously interpreted as partly pierced salt diapir. This structure developed in Triassic to Jurassic times as a listric normal fault zone detached above the salt layer, resulting from activity of a master fault present within the pre-Zechstein basement. Two pulses of increased extension could be inferred for Oświno fault zone: Late Triassic and Mid-Late Jurassic. The Oświno fault zone was reactivated in the Late Cretaceous due to the compression responsible for inversion of the MPT. Inversion-related uplift of the axial part of the MPT created a morphological gradient and the increased pressure of uplifted overburden rocks directed towards its flanks that also contributed to reactivation of the Oświno fault zone. This fault zone, together with the Drawno-Człopa salt diapiric structure and graben system of the Fore-Sudetic Monocline, have developed due to decoupled evolution of the Mid-Polish Trough.

Opis:
In June of 1843 Roderick Murchison visited Poland to overview local geology in order to fill the gap between the results of his Russian campaign (1840-1841) and the familiar geology of Western Europe. Recent examination of Murchison's hand-written "Journal" and field notebooks in the archive of the Geological Society of London allows a detailed reconstruction of his visit in the Polish territories. During the five-days "charge" across the Holy Cross Mountains the famous British geologist, accompanied by the outstanding Polish colleague Ludwik Zejszner, had collected plenty of observations that were later partly quoted in Murchison's monumental treatise about the geology of Russia (1845). Among the most important new findings is the identification of the Devonian sediments earlier included by Jerzy Bogumił Pusch (1833–1836) in the Formation of Übergangs Kalkstein und Breccie (Transitional Limestone and Breccia). Murchison’s visit and its results are echoed in later papers by domestic scientists, particularly those by Zejszner. The latter was the first Polish student of the Holy Cross Mountains geology who extensively introduced chronostratigraphic units established by Murchison, including the Silurian and Devonian in particular.

Opis:
Two-dimensional modelling of hydrocarbon generation, expulsion, migration and accumulation pro- cesses in SE Poland between Tarnów and Rzeszów was carried out for five source rock horizons, i.e. the Ordo- vician, Silurian, Middle Devonian–Lower Carboniferous carbonates, Lower Carboniferous clastics, and Middle Jurassic. Five cross-sections in the study area allowed the reconstruction of timing and range of petroleum processes. The best source rocks related to the Ordovician and Silurian shales and mudstones reached “oil window” maturity within the entire study area and locally also reached the “gas window”. Generation of hydro- carbons was observed from all five source rocks, but the Ordovician and Silurian source rocks generated two and three times more hydrocarbons than the Lower Carboniferous and Jurassic source rocks, respectively. Expulsion took place only in case of the Lower Palaeozoic source rocks, but the volume of expelled hydrocarbons differed across the area. Hydrocarbons migrated from the Ordovician and Silurian source rocks to the Upper Jurassic (carbonates) and Upper Cretaceous (sandstones) reservoirs or to the Upper Palaeozoic carbonates in connection with the emplacement of the Carpathian thrust belt during the Miocene. Faults formed main migration pathways and hydrocarbons accumulated in structural and stratigraphic traps, located in the vicinity of faults. In places, traps are associated with a deep Miocene erosion surface. The onset of hydrocarbon generation took place during the Neogene, mainly the Miocene, but in the north, generation and expulsion started earlier – at the end of the Mesozoic.

Opis:
Petrological studies of core samples, integrated with mesostructural analysis of cores, and coupled with results of seismic data interpretation allowed to interpret evolving reservoir properties of dolostones of the Frasnian Werbkowice Mb. These crystalline and partly vuggy rocks form main reservoir horizons of the Ciecierzyn and Mełgiew A gas fields in the central Lublin Graben. The optimum reservoir properties were attained following the main phase of regional dolomitization and accompanying CaCO3 dissolution. These processes occurred after renewed subsidence in Viséan and before main phase of the Variscan inversion in late Westphalian. In Late Silesian, after the onset of hydrocarbon generation, porosity was partly filled by a dolomite cement. The most important agent of porosity destruction, however, was a precipitation of anhydrite cement preceding main phase of compressional deformations. The latter led to a localized development of open fracture systems which, however, were soon filled with various cements related to dissolution-reprecipitation processes. After compressional event, the stress regime evolved towards strike-slip and extensional, which created fractures allowing migration of hydrocarbons to newly formed structural traps. Several observed structures indicate negligible post- inversion deformations, thus facilitating preservation of earlier formed hydrocarbon accumulations. However, successive stages of secondary migration could have occurred during indefinite time under strike-slip and extensional regime recorded as a distinct set of mesostructures.

Opis:
Lateral changes in the thickness of strata and petrophysical parameters within the Zechstein succession (salt pillows and domes) can cause many problems in seismic exploration of the aeolian Rotliegend formations, which are prospective for hydrocarbons. An assessment of the influence of halokinesis on the seismic imaging of the sub-Zechstein strata in NW Poland (Obrzycko–Szamotuły area, to the SW of the Mid-Polish Swell) utilised time-to-depth conversion with different, seismic-geological models. Various, seismic velocities were used in models for the Zechstein and the Mesozoic successions, namely velocities, dependent on the thickness of particular rock successions, on their depths, and velocities, determined from seismic inversion. The results show opposite reflection patterns for the seismic section imaged in the time and depth domains. The synclinal arrangement of the strata boundaries in the depth model is represented by convex-upwards reflection events on the seismic section. The pull-up of reflection events, associated with the sub-Zechstein strata, observed on the seismic sections, is mainly a result of both the greater thickness of the Zechstein salt within the salt structures (pillows, diapirs) and the increase in velocity contrast between the salt body and the Mesozoic strata.

Opis:
Analysis of previously available stratigraphic data coupled with the re-interpretation of seismic profiles calibrated by boreholes has allowed the construction of a new tectonic model of evolution of the Gdów “embayment” – a tectonic re-entrant located along the Carpathian front east of Kraków (southern Poland). This model shows that the main phase of localized fault-controlled subsidence took place in the Early Badenian and was associated with deposition of the locally overthickened Skawina Formation. Also, deposition of evaporites of the Wieliczka Formation seems to have been tectonically controlled by local basement faulting. Supra-evaporitic siliciclastic deposits have developed as a result of overall north-directed sediment progradation from the eroded Carpathian belt towards the Carpathian Foredeep. During the final stages of development of the Carpathian fold-and-thrust wedge the previously subsiding Gdów “embayment” area was uplifted and basement faults were reactivated either as reverse faults or as low angle thrust faults. Along the leading edge of this inverted structure a triangle zone developed, with backthrusting along the evaporitic level. As a result, overthickened evaporites, formed in local tectonically-controlled depressions within the area of the Gdów “embayment” area have been strongly folded and internally deformed.

Regional analysis and mapping of various geophysical data has been recognized as an important — even crucial — element of geological studies for many years. Due to rapid development of advanced numerical tools it is presently possible to construct, maintain and comprehensively analyse even very large geo-databases, including seismic, gravity, magnetic, geothermal and other geophysical data. In many countries, national geological surveys, commercial companies and research institutions are involved in mapping projects focused on spatial representation of geophysical data that could later be used for various studies. Recently, new policy of the Polish Ministry of Environment regarding geological cartography in years 2005–2020 has been declared (cf. Ber & Jezierski, 2004). In this document, geological cartography is used as a rather wide term that includes also other geo-disciplines like geoenvironmental studies or surface geochemistry. Among them, mapping of geophysical data is also mentioned. In this paper, short overview of the current state-of-the-art of selected aspects of regional geophysical mapping in Poland is given, with some remarks regarding potential directions of future work.

Opis:
The Cenozoic tectonic evolution of the Polish Platform reflects repeated changes in loading condi tions at the Al pine–Carpathian and Arctic–North Atlantic margins of the European continent. After the Late Cretaceous–Paleocene main phase of the Mid-Polish Basin inversion, a second phase of limited uplift of the Mid-Polish Swell occurred during the Middle–Late Eocene. End Eocene and Early Oligocene subsidence of narrow grabens on the Fore-Sudetic Monocline was coeval with normal fault ing in the East Alpine foredeep basin and the development of the Central European rift system. At the sametime the Outer Carpathian flysch basins were rearranged, presumably in response to the build-up of compressional stresses at crustal levels, whilst subsidence and erosion patterns changed in the Carpathian Foreland from being dominated by the NW–SE trending Mid-Pol ish Swell to being controlled by the development of the W–E trending Meta-Carpathian Swell. At the end of the Oligocene the Fore-Sudetic graben system propagated into the area of the Trans-European Suture Zone and the Sudetes and remained active during the Early and Middle Miocene. This was paralleled by intensified subduction activity and thrusting of the Carpathians and the development of their flexural foredeep basin. A short early Sarmatian episode of basement in volving transpression along the SW margin of the Mid-Pol ish Swell correlates with the termination of north-directed nappe transport in the Outer Carpathians. This was followed by eastward migration of the subsidence centre of the Carpathian Foredeep Basin and the gradual termination of tectonic activity in the grabens of the Polish Lowlands. After a period ofpost-orogenic relaxation the present-day compressional stress regime built up during the Pliocene and Quaternary. Intensified ridge push forces exerted on the Arctic–North Atlantic passive margins contribute to this compressional stress field that is dominated by collision-related stresses reflecting continued indentation of the Adriatic Block. This sequence of events is interpreted in terms of changing tectonic loads in the Carpathians, Alps and at the NW passive margin of Europe. The complex and diachronous interaction of mechanically coupled and uncoupled plates along collision zones probably underlies the temporally varying response of the Carpathian Foreland that in addition was complicated by the heterogeneous structure of its lithosphere. Progressively increasing ridge push on the passive margin played a secondary role in the stress differentiation of the study area.
