    Opis:
    In the last years, the conchostracan stratigraphy has become a popular method for distingushing the Permian/Triassic boundary in intracontinental settings. This paper provides a background of chronostratigraphic interpretation of the new method. Several problems are reported, from which the most important are: 1 – lack of consequent documentation of the index species, 2 – indirect correlation with the conodont stratigraphy through the sporomorph spectra, 3 – lack of definition and documentation of supporting palynologic zones, 4 – difficulties in taxonomic determinations of conchostracan. Revision of the method by several independent research teams is suggested.

    Frontally fluidized slump sheet containing water-and-sediment escape structures, interpreted as earthquake-driven deposit occur in Permian conglomerates in Golińsk (Saxonian, Mieroszów Conglomerate Member) in the Intrasudetic Synclinorium. Their internal architecture, lithology and position within the slump sheet suggest a rheologically differentiated reaction of sediment to the seismic shock - from brittle failure to liquefaction. The onset of the latter involved diffusional grain displacement in zones of contrasting density resulted from brittle fracture in unconsolidated sediment.

    Opis:
    The uppermost Permian in the NWHoly Cross Mountains is represented by red mudstones with sandstone and conglomerate interbeds, forming the PZt cyclothem (dated by miospores of the Lueckisporites virkkiae Bc Zone), which grade upwards into the Siodta Formation. This succession is overlain by sandstones and mudstones of the Jaworzna Formation yielding the lowermost Triassic spore-pollen assemblage of the Lundbladispora obsoleta- Protohaploxypinus pantii Zone. Mudstones of the Siodta Formation reveal mottling structure with numerous root traces, rhizobreciation, as well as nodular and bedded calcretes. The root -Mader structures are represented by calcite tubules and root moulds, the latter filled with dark red calcareous mudstones. The presence of root traces in the Siodta Formation clearly indicates an increase of substrate moisture in contrast to the underlying PZt cyclothem. The mottled red mudstones were deposited in the playa-lacustrine depositional system and lost their primary structure due to rooting and other pedogenic processes. Carbonate nodules and thin indurated calcretes are related to periods of lower sediment accumulation rate or even non-deposition periods favouring development of continental carbonates. A relatively rapid switch to the alluvial depositional system represented by the Jaworzna Formation appears to be coeval to the increased sediment flux in terrestrial setting, postulated by Newell et al. (2010) at the Permo-Triassic boundary, driven by a devegetation event of upland catchments.

    Opis:
    The geosite Zygmuntówka (Sigismund ) quarry, located at Czerwona Góra near Chęciny in SW part of the Holy Cross Mountains, is the oldest and the most famous among the so-called Chęciny „marble” quarries which provided stones for constructing numerous important buildings in the region and beyond. Upper Permian conglomerates (Czerwona Góra Formation), with a thickness of several tens of metres, outcrop in this area. The conglomerates are clast- and locally mud-supported and consist of light grey and beige carbonate pebbles and cobbles chaotically distributed within the reddish-brown silty-carbonate-ferriferous matrix. The conglomerates represent continental alluvial fan deposits deposited under arid and semiarid climate conditions. The quarry, of a regional rank, is well suited for both geoeducation and geotourism purposes.

    Opis:
    The single-grain U-Pb dating of most zircon grains separated from the Zalas rhyodacites gave mean age of the magma emplacement 294.2 š 2.1 Ma. Some zircons, however, displayed younger ages (268.7š 3.4 Ma), probably related to metasomatic alterations of these rocks. The paleomagnetic ages of the Zalas intrusion and its metasomatosis are slightly younger. It is probably connected with a certain error of time calibration of the reference apparent polar wander path used for paleomagnetic dating.

    Opis:
    The question of the eastern extent of the Variscan externides in the Polish Lowlands is a subject of ongoing scientific debate. The key to resolve this problem is to provide a good seismic image of the pre-Permian strata. Unfortunately, the industrial seismic profiling brings sparse information from below the Zechstein, thus in 2003, a special seismic experiment called GRUNDY 2003 has been organised. The acquisition system was based on the deep seismic sounding equipment and was targeted at the recognition of Palaeozoic strata. The results in form of the 3D tomographic velocity field and the migrated depth section form the basis for the geological interpretation. Deduced geological model suggests the existence of two different geological media below the Permian strata. The likely interpretation is that it is the contact zone of the Variscan externides with their foreland. Obtained results are of a great importance for the hydrocarbons exploration perspectives.

    Opis:
    Clastic dikes have been evidenced in Permian conglomerates occurring near Kudowa Zdrój in the Nachod Basin, the Sudetes, NE Bohemian Massif. The lithology of the dikes is the same as that of the polimictic conglomerate hosting them; they only differ in textural characteristics. The spatial orientation of the dikes points out to their genetic relationship with a nearby fault that, in a map view, separates Permian and Cretaceous formations. The dikes must have intruded after tectonic rotation of conglomerate beds on the fault to a position similar to the present one and they represent record of post-diagenetic seismotectonic events.

    Opis:
    The regional subdivisions of major structural complexes distinguished in the Polish territory have been systematically corrected and updated parallel with accumulation of new geological and geophysical data. Regional units are established not only basing on their tectonic characteristics but also on other criteria including sedimentary and subsidence development, magmatism, metamorphism and crustal structure. In future, new units should be defined and older ones redefined in a possibly objective, descriptive way. However, the interpretative approach is unavoidable particularly when older, largely concealed structural complexes are concerned. Therefore, the establishment of formal criteria and "official"regional subdivisions analogous to formal stratigraphic units, seems inappropriate. Proposed schemes or modifications of previous subdivisions will serve as consistent and clear regional reference framework in geological and geophysical studies if they will meet few basic methodological and terminological requirements. Among the most important prerequisites is a clear definition of boundaries of particular units against most recent solid geological maps in a scale of 1:1 000 000 or larger. In accordance with the outlined guidelines the authors' version of the regional framework of Polish sub-Cenozoic and sub-Permian (Variscan) geological units is presented. The subdivisions are based on the modified scheme published by Dadlez (1998) and that by Narkiewicz (2007), respectively. We did not attempt to present a pre-Variscan (Caledonian) regional framework, except for the stable area of the East European Platform devoid of the Devonian-Carboniferous cover. Given the present state of research, such subdivision would be very speculative, reflecting only one of several possible interpretative variants of the Polish Lowlands deep structure.

    Opis:
    The Polish Permian Basin (PPB) is a part of the Southern Permian Basin in theWestern and the Central Europe. Results of burial and thermal analyses as well as a configuration of the Moho surface of the Polish Basin suggest the asymmetrical basin model. History of the Polish Basin reveals that the Late Permian and the Early Triassic periods represent the main rifting phase and its later development resulted from thermal relaxation. During the Late Triassic and the Jurassic time some cooling of rift heat field took place, but the turning point in thermal evolution of the Polish Basin was at the Jurassic/Cretaceous boundary when the south-western part of the Polish Basin was uplifted and intensively eroded. The knowledge on the Permian Basin in Poland is chiefly connected with petroleum exploration. The gas fields are located mainly in the Rotliegend reservoirs. The Zechstein deposits, overlying the Rotliegend, are also in the area of economic interest: hydrocarbons occurring in carbonate deposits of the Werra (Zechstein Limestone - Ca1 ) and Stassfurt (Main Dolomite - Ca2) cyclothems. Several tens gas fields have been hitherto discovered within the Rotliegend sandstones and the Zechstein limestones. Reservoirs are the clastic, terrestrial deposits of the Lower Permian and calcareous, biogenic carbonates of the Zechstein. Evaporates, mainly salts of the Werra cyclothem, are the regional sealing for the mentioned reservoirs. Natural gas accumulated in the Rotliegend sandstones and the Zechstein limestones is of the same origin: it was generated from organic matter occurred in the Carboniferous rocks and it migrated to higher places where it became concentrated within favourable structural or lithofacies conditions. High nitrogen content in the natural gas from the Polish Permian Basin is explained that nitrogen is generated from an organic matter within a sedimentary basin at higher temperatures than methane. Location of high helium concentration corresponds to the area of highest heat flow during the Late Permian, Triassic and Jurassic times, evidencing the Late Permian-Early Mesozoic rifting process. Numerous oil gas fields discovered in the Main Dolomite (Ca2) unit constitute it as one of the most important exploration target in the Polish Basin. It composes the closed hydrodynamic system sealed from the top and the bottom by evaporates. Both the source rocks and reservoirs are characteristic for this unit. Influence of the burial and thermal history of the Polish Basin on a petroleum play generation within the Main Dolomite unit is clearly visible. The previous and the present petroleum discoveries in the Polish Permian Basin, comparing to the other petroleum provinces in Poland, indicate it as a main exploration target.

    Opis:
    The paper presents results of detailed research of pore space in the Upper Carboniferous and Lower Permian sandstones and those from the Upper Carboniferous/Lower Permian transitional section. This is followed by a preliminary assessment of reservoir properties against the background of diagenetic processes. The samples were collected from 11 boreholes. The research included standard petrological investigations supported by a digital image analysis of thin sections. Compaction and cementation were the main processes reducing porosity in all the sandstones. Cementation locally reduced primary porosity to approximately 80%. Compaction was much less active. The sandstones are characterized by primary and secondary porosity. Secondary intergranular as well as intercrystalline and intracrystalline porosity developed as a result of diagenetic dissolution of feldspar grains and cements. Variability of petrophysical parameters can be a result, among others, of lithological and facies development. Upper Carboniferous and Upper Carboniferous/Lower Permian sandstones show the best reservoir properties. Lower Permian sandstones are characterized by variable properties.

    Opis:
    Investigation of the Permian Basin in the western part of the Polish Lowland was initiated in 1961 when the Rybaki field was discovered - the first one outside the Carpathians in Poland. The Main Dolomite (Ca2) in the eastern part of the Wielkopolska Platform, located in western Poland, is characterized by a significant variety of microfacies, hence this research is aimed at better interpretation and understanding of depositional environments of current reservoir rocks as well as possibility of identification of facies distribution within the investigated carbonate platform. A detailed microfacies analysis of the Main Dolomite was conducted, which was supported by core logging. The author interpreted depositional environments and generated a 3D model of the top of the Main Dolomite using seismic reflection data. An attempt to correlate microfacies between the analyzed wells was also performed. Integrated analyses of thin sections and drill cores from 4 wells allowed me to interpret the depositional environments of the Main Dolomite. The generated 3D model of the top of the Main Dolomite provided a better insight into subsurface tectonics, paleogeography of the analyzed area and a better understanding of depositional lithofacies environments.

    Opis:
    The attempt to divide the Upper Silesian Block and the Małopolska Block into tectonic units has been based on a general map at scale of 1:1000000, without Permian-Mesozoic and Cenozoic strata. Cartographic, general and monographic works regarding formation of Precambrian basement of both of the blocks have been discussed and presented, and data concerning development of sedimentation, tectonics, and structure of the Paleozoic cover of the blocks were the background for the suggested division. The Upper Silesian Block is a part of a larger unit determined as the Brunovistulicum, which together with the Brno Block are entirely located within the borders of the Czech Republic. The Brunovistulicum and the Małopolska Block vary in formation of Precambrian basement and covering Paleozoic formations, what proves different paleogeographical-facial and paleotectonic development. Current data do not allow determining their southern range, where both units are within the range of the orogeny of the Outer Carpathians and quite possibly in the range of the Inner Carpathians. The boundary of the Brunovistulicum and the Małopolska Block along the part between Lubliniec and Cracow and farther to the vicinity of Bochnia and Nowy Sącz is relatively well defined and documented. It is a narrow Cracow-Lubliniec fault zone, approximately 500 m wide, cutting and moving all rock series of the Precambrian and the Paleozoic. The fault zone of the Odra River probably forms its NW continuation. The following tectonic units have been distinguished in the Upper Silesian Block: 1) Moravian-Silesian Fold-and-Thrust Belt, 2) Upper Silesian Fold Zone, 3) Upper Silesian Trough, 4) Bielsko-Biała Dome, 5) Rzeszotary Horst, 6) Liplas Graben. There is only one tectonic unit distinguished in the Małopolska Block-Kielce Fold Belt, dipping towards NW-SE, along the NE boundary of the block. Paleozoic formations building the unit represent thrust fault structure. In this case, the Kielce Fold Belt significantly varies from the other parts of the Małopolska Block, where Paleozoic formations build numerous small block structures.
