Opis:
A summary of known crinoid taxa in the Polish part of the Triassic Germanic Basin, including their presence elsewhere, is documented. At present, 13 taxa and 3 ecophenotypes of crinoids have been recorded from that area, only one of them being endemic. In the Lower Muschelkalk and lower part of theMiddleMuschelkalk, taxa widespread both in the Tethys and Germanic Basin, or Tethyan taxa, dominate. In the Upper Muschelkalk crinoids are very rare in Poland, being represented by Encrinus liliiformis and Holocrinus sp. Many of the species occurring in the central part of the Germanic Basin in the Upper Muschelkalk have not been recorded in the eastern part of the basin. The degree of endemism of the crinoid fauna in theMuschelkalk is markedly lower than the degree of endemism of the rest of the benthonic macrofauna. This probably resulted from huge number of crinoids forming "crinoid gardens" that produced large number of larvae, increasing the chances of successful geographical expansion of crinoids.

Opis:
Palaeomagnetic results are presented for 205 samples of cores from the Książ Wielkopolski IG-2, Woźniki K1 and Patoka 1 wells, drilled in the Polish part of Germanic Basin. The magnetic polarity stratigraphy is based on the inclination of the characteristic remanent magnetization, isolated in 60% of the total samples and found to be in general agreement with the expected Late Triassic inclination at the sampling sites. A total of 22 magnetozones from the integration of the three records correspond to about 25% of the published polarity zones for the Upper Triassic sediments that were combined in the worldwide composite polarity-time scale. The magne- tic polarity pattern, defined for the Schilfsanstein, fits very well with the one defined in the Tethys area for the upper part of the Julian sub-stage. According to the magnetostratigraphic data, the uppermost part of the Upper Gypsum Beds (equivalent to the Ozimek Member of the redefined Grabowa Formation) and the lowermost part of the Patoka Member, containing the Krasiejów bone-breccia horizon, can be correlated with the latest Tuvalian (~228.5 Ma) or with the middle part of Lacian (~225 Ma). However, if the “Long-Tuvalian” option for the Late Triassic Time Scale is taken into consideration, the parts of these substages mentioned above should be correlated with ~221.5 Ma and ~218.5 Ma, respectively.

Opis:
At present, hydro-geothermal resources in which waters in bores are the carrier of heat energy have commercial importance in Poland. Geothermal waters should feature the highest possible temperature in the outflow, low mineral content, high capacity and low deposit depth. Even though geothermal energy is included in renewable sources of energy, complete depletion of the deposit is the largest risk in extracting geothermal waters. This is why these waters should also feature deposit renewability. There are currently several geothermal provinces with beneficial geothermal conditions in Poland, with the area of the Podhale Basin in the Inner Carpathians region being regarded as the most promising. The Podhale deposit also meets all of the above listed conditions. The possibility of using hydrothermal energy in Poland is practically available throughout the country, but operational use of hot groundwater must be profitable for investors. From another point of view, the environmental impact of such investments should be minimized. This paper is concerned with the special variety of temperature of geothermal waters extracted in the area of the Podhale Basin, which is the basic aspect in using deposits of this type.

Opis:
Progress in geological, geophysical and drilling sciences during the past 30 years has introduced to hydrocarbon exploration the concept of petroleum system, understood as an analysis of the factors necessary forformation and preservation of oil and natural gas deposits. Thefinal evaluation ofpetroleum system is the product of allfactors involved in the formation of hydrocarbon accumulations, which must be preserved proper chronology of events in the geological space. Such interdependences build often synergistic or antagonistic configurations. These configurations are called critical elements of the petroleum system. Reliable and comprehensive analysis of critical elements ofpetroleum system in sedimentary basins in Poland lets identify potential new areas of hydrocarbon exploration. In this context, a particularly promising area is the petroleum system of the Pita Claystone Formation (central part of the Polish Rotliegend Basin) and deep “Carpathians” with their palaeo-mesozoic basement and deeper part of the Carpathian Foredeep.

Opis:
The north-eastern part of Nidziańska Basin, near Staszów, boasts a large grouping of small but relatively deep lakes of karst origin. In 2010, 26 of them underwent regular measurements of the temperature of their surface layer of water. The results show that although the basins are situated close to each other and the area has similar characteristics, the temperature differs significantly. The thermal differences reach 11.6ºC. The warmest lakes appear to be Lake Łajba, Duży Staw, Lakes Torfowe I and Torfowe II. However, the coldest surface water is in lakes Piąty Staw, a small unnamed lake located near Lake Ciemne and an unnamed lake sandwiched between Lake Szyja and Lake Jasne.The fact that the temperature of the water goes up results directly from solar radiation, which was the strongest in the case of Lake Łajba, located in an open area. However, the coldest basins were located in the central parts of the lakes of the floating peat islands. Those biogenic islands are perfect “insulators”, protecting the water from thermal radiation. Moreover, the lakes which are fed with soligenous water supplies, tend to have a lower temperature.

In the paper, the authors present the results of seismic reservoir characterization of shale gas deposits of the Lower Silurian and Ordovician (Sasino Formation and Jantar Formation), which are localized within the onshore part of the Baltic Basin, N Poland. For this purpose, acoustic inversion of seismic data and petrophysical analysis of well-log data were incorporated. The new approach that the authors used for acoustic inversion was the resolution enhancement algorithm, known as spectral blueing, before proceeding with the acoustic inversion process. The spectral blueing procedure enhances the seismic spectrum by weighting it with the well reflectivity spectrum. The resulting enhanced seismic volume manifests itself in higher energies of the high frequency component, while keeping the frequency range constant. With the results of acoustic inversion after the spectral blueing procedure, the authors were able to define two more potential exploration sites within the Ordovician deposits.

Opis:
The paper presents general information on variability of coalbed methane bearing capacity in tectonic zones, faults, rock fissures etc. Methane occurrences were compared in two tectonic zones of the Upper Silesian Coal Basin - the zone of fault-block tectonics and the folded one. The influence of big size faults (i.e. Bzie-Czechowice fault) and neighbouring fissures on methane bearing capacity is strongly marked in the zone of fault-block tectonics. The most important tectonic factors influencing the methane occurrence in the folded zone are Chwałowice and Jejkowice depressions and also Orlová and Michalkovice overthrusts. The methane bearing zones are parallel to Chwałowice and Jejkowice depressions bottom axis. Presence of Carpathian nappes intensifies rock fissuring process, which could involve the methane migration and cause degasification of coal seams lying under these nappes.

Opis:
Limestones designated the Štramberk-type are the most common carbonate exotic clasts (exotics) embedded in the uppermost Jurassic–Miocene flysch deposits of the Polish Outer Carpathians. About 80% of stratigraphically determinable carbonate exotics from the Silesian, Sub-Silesian and Skole units (nappes) are of Tithonian (mostly)–Berriasian (sporadically Valanginian) age. A study of these exotics revealed eight main facies types: coral-microbial boundstones (FT 1), microencruster-microbial-cement boundstones (FT 2), microbial and microbial-sponge boundstones (FT 3), detrital limestones (FT 4), foraminiferal-algal limestones (FT 5), peloidalbioclastic limestones (FT 6), ooid grainstones (FT 7), and mudstones-wackestones with calpionellids (FT 8). Štramberk-type limestones in Poland and the better known Štramberk Limestone in the Czech Republic are remnants of lost carbonate platforms, collectively designated the Štramberk Carbonate Platform. Narrow platforms were developed on intra-basinal, structural highs (some of them are generalized as the Silesian Ridge), with their morphology determined by Late Jurassic synsedimentary tectonics. An attempt was made to reconstruct the facies distribution on the Tithonian–earliest Cretaceous carbonate platform. In the inner platform, coral-microbial patch-reefs (FT 1) grew, while the upper slope of the platform was the depositional setting for the microencruster-microbial-cement boundstones (FT 2). Microbial and microbial-sponge boundstones (FT 3), analogous to the Oxfordian–Kimmeridgian boundstones of the northern Tethyan shelf (also present among exotics), were developed in a deeper setting. In the inner, open part of the platform, foraminiferal-algal limestones (FT 5) and peloidal-bioclastic limestones (FT 6) were deposited. Poorly sorted, detrital limestones (FT 4), including clastsupported breccias, were formed mainly in a peri-reefal environment and on the margin of the platform, in a high-energy setting. Ooid grainstones (FT 7), rarely represented in the exotics, were formed on the platform margin. Mudstones-wackestones with calpionellids (FT 8) were deposited in a deeper part of the platform slope and/or in a basinal setting. In tectonic grabens, between ridges with attached carbonate platforms, sedimentation of the pelagic (analogous to FT 8) and allodapic (“pre-flysch”) Cieszyn Limestone Formation took place. The most common facies are FT 4 and FT 1. Sedimentation on the Štramberk Carbonate Platform terminated in the earliest Cretaceous, when the platform was destroyed and drowned. It is recorded in a few exotics as thin, neptunian dykes (and large dykes in the Štramberk Limestone), filled with dark, deep-water limestones. Reefal facies of the Štramberk Carbonate Platform share similarities in several respects (e.g., the presence of the microencrustermicrobial-cement boundstones) with reefs of other intra-Tethyan carbonate platforms, but clearly differ from palaeogeographically close reefs and coral-bearing facies of the epicontinental Tethyan shelf (e.g., coeval limestones from the subsurface of the Carpathian Foredeep and the Lublin Upland in Poland; the Ernstbrunn Limestone in Austria and Czech Republic). Corals in the Štramberk Limestone and Štramberk-type limestones are the world’s most diverse coral assemblages of the Jurassic–Cretaceous transition. The intra-basinal ridge (ridges), traditionally called the Silesian Cordillera, which evolved through time from an emerged part of the Upper Silesian Massif to an accretionary prism, formed the most important provenance area for carbonate exotic clasts in the flysch of the Silesian Series. They are especially common in the Lower Cretaceous Hradiště Formation and the Upper Cretaceous–Paleocene Istebna Formation. The Baška-Inwałd 204 M. HOFFMANN Et Al. In the Polish Outer Carpathians, shallow-water carbonate sedimentation is recorded only by carbonate clasts, redeposited bioclasts, and very rare, small, unrooted, poorly exposed klippen. Clasts of limestones are exotic to the dominant siliciclastic, uppermost Jurassic–Miocene flysch deposits. They were derived from extrabasinal and intra-basinal source areas of the Carpathian rocks, which periodically emerged and were destroyed. Such rocks were described as “exotic” since the 19th century (“exotischen Graniten”, “exotische Blöcke”; Morlot, 1847; Hohenegger, 1861). In the general geological literature, the term “exotic clasts” is usually used (Flügel, 2010, p. 172), whereas in the Polish geological literature, the term “exotics” (Polish “egzotyki” including also carbonate exotics), is also commonly applied. On the basis of fossils, facies and microfacies, these clasts (pebbles, rarely blocks) are mostly described as Devonian–Carboniferous (Malik, 1978, 1979; Burtan et al., 1983; Tomaś et al., 2004) and Upper Jurassic–lowermost Cretaceous (the present paper and references therein), more rarely Middle Jurassic (Książkiewicz, 1935, 1956a; Barczyk, 1998; Olszewska and Wieczorek, 2001), Early Cretaceous (Oszczypko et al., 1992, 2006, 2020; Krobicki et al., 2005), Late Cretaceous (Książkiewicz, 1956a; Gasiński, 1998) and Palaeogene in age (Leszczyński, 1978; Rajchel and Myszkowska, 1998; Leszczyński et al., 2012; Minor-Wróblewska, 2017). At the beginning of these studies, the focus was on small, unrooted klippen, namely the Andrychów Klippen (called also Klippes) near Wadowice (Zeuschner, 1849; Hohenegger, 1861; Uhlig, 1904; Książkiewicz, 1935, 1971b; Nowak, 1976; Gasiński, 1998; Olszewska and Wieczorek, 2001), and in Kruhel Wielki, near Przemyśl (Niedźwiedzki, 1876; Wójcik, 1907, 1913, 1914; Bukowy and Geroch, 1956; Morycowa, 1988; Olszewska et al., 2009), now poorly exposed. Subsequently, exotic pebbles, much more common and providing data on more facies, were studied more frequently. The first attempt to describe exotics, including crystalline rocks, was presented by Nowak (1927). Jurassic–Cretaceous carbonate exotics at Bachowice, containing facies unknown at other localities in the Polish Outer Carpathians, were described by Książkiewicz (1956a). The preliminary results of studies, which encompassed the entire spectrum of carbonate exotics from the western part of the Polish Outer Carpathians, were presented by Burtan et al. (1984). Malik (1978, 1979) described both Palaeozoic and Mesozoic carbonate clasts in the Hradiště Sandstone of the Silesian Unit, but other studies were mostly concerned with the Štramberk-type limestones from selected outcrops. The studies of these limestones, if concerned with exotics at many localities, were focused on their fossil content (e.g., Kołodziej, 2003a; Bucur et al., 2005; Ivanova and Kołodziej, 2010; Kowal-Kasprzyk, 2014, 2018) or presented only the preliminary results of facies studies (e.g., Hoffmann and Kołodziej, 2008; Hoffmann et al., 2008). Carbonate platforms, the existence of which was deciphered from detrital carbonate components, are called lost carbonate platforms (e.g., Belka et al., 1996; Flügel, 2010; Kukoč et al., 2012). Clasts and other shallowwater components are, metaphorically, witnesses to lost carbonate factories (the term is taken from Coletti et al., 2015). Analyses of the age and lithology of exotic clasts have been applied in the reconstruction of the provenance areas of the clasts and their palaeogeography and the development of the sedimentary sequences of the Polish Outer Carpathians (e.g., Książkiewicz, 1956b, 1962, 1965; Unrug, 1968; Oszczypko, 1975; Oszczypko et al., 1992, 2006; Hoffmann, 2001; Krobicki, 2004; Słomka et al., 2004; Malata et al., 2006; Poprawa and Malata, 2006; Poprawa et al., 2006a, b; Strzeboński et al., 2017; Kowal-Kasprzyk et al., 2020). Štramberk-type limestones are most common among the exotics. It is a field term that refers to limestones, mostly beige in colour, that are supposed to be the age and facies equivalents of the Tithonian–lower Berriasian Štramberk Limestone in Moravia (Czech Republic; Eliáš and Eliášová, 1984; Picha et al., 2006). The Štramberk Limestone and the Štramberk-type limestones of both countries were deposited on platforms, attached to the intrabasinal ridges and margins of the basin of the Outer Carpathians. These platforms are collectively termed the Štramberk Carbonate Platform. The terms “Štramberk Limestone” and “Štramberk-type limestones” have been widely used in the area of the former Austro-Hungarian Empire for the field description of shallow-water limestones of assumed Late Jurassic age, usually occurring within flysch deposits of the Outer Carpathians. Upper Jurassic–lowermost Cretaceous shallow-water limestones in Romania (commonly forming mountains or ridges, e.g., Pleş et al., 2013, 2016), in Bulgaria and Serbia (Tchoumatchenco et al., 2006), and Ukraine (Krajewski and Schlagintweit, 2018), and in Turkey (Masse et al., 2015) sometimes are referred to as the Štramberk-type limestones as well. In the Austrian-German literature similar limestones in the Alps are known as the Plassen Limestone (e.g., Steiger and Wurm, 1980; Schlagintweit et al., 2005). Biostratigraphic studies revealed that some carbonate clasts, accounting for several percent of the exotics and commonly Ridge and the Sub-Silesian Ridge were the source areas for clasts from the Silesian and Sub-Silesian units (e.g., in the Hradiště Formation), while the Northern (Marginal) Ridge was the source for clasts from the Skole Unit (e.g., in the Maastrichtian–Paleocene Ropianka Formation).

Opis:
The Zechstein Limestone of the Bonikowo 2 borehole is composed of limestone with varied dolomite content and is slightly thicker (3.4 m) than other supposed condensed sections in SW Poland. The microfacies (mostly bioclastic wackestones-packstones) are characteristic of open marine limestone deposited in deep shelf environments. The common occurrence of echinoids in all parts of the section, except close to its top, indicates no essential change in sea water salinity. However, the palaeotemperature interpretation of the highest δ18O value of calcite recorded in the Bonikowo 2 borehole (+0.32‰) indicates a temperature of 22.9°C when a δ18O of water = 2‰ is assumed. The δ13C and δ18O curves for calcite and dolomite are similar in shape, and their mean values are similar: +1.8 ±1.5‰ for calcite, respectively, and +1.9 ±2.3‰ and –4.3 ±2.4‰, –3.8 ±4.3‰ for dolomite. There is a recrystallized interval in the lower part of the section with both δ13C and δ18O values reduced. This may be regarded as an aerobic equivalent of the Kupferschiefer. The diversity and abundance of foraminifers is significant throughout the section studied; lagenids prevail, and this is considered to be due to the dysaerobic conditions throughout the duration of deposition of the Zechstein Limestone.

Opis:
The scheme in which the Carpathians, Carpathian Foredeep and Polish Lowland are distinguished as the hydrocarbon prospective zones was used hitherto in Poland. Good geological diagnosis of Poland area enables to distinguish the petroleum provinces in terms of basin analysis (methodology). This procedure are based on an integration of multidisciplinary geological and geophysical data with into a petroleum play concept. Results of drillings and petroleum play procedures allow to predict boundaries of petroleum provinces. Effects of basin analysis with regards to the stratigraphy of hydrocarbon-bearing areas are presented in Figure 1. All these prospective areas (Fig. 1) have been matched into five independent units (Fig. 2) which could be defined as following petroleum provinces: Pomerania, Wielkopolska, Ma3opolska, Lublin and Gdansk. These petroleum provinces are only the parts of sedimentary basins the individual development of which enabled generation, migration and preservation of hydrocarbons. Location of the above mentioned petroleum provinces is also brightly reflected on the map of crustal consolidation (Fig. 3): every province in Poland has its own individual geologic history.

Opis:
The authors present a first record of Flammulina ononidisin Poland. This species was characterized in respect of macro- and micromorphological features, which were illustrated with the original figures and photographs. The habitat conditions of the recorded site were also described. A short discussion concerning the similar species and the ecology and threats of presented fungus species is provided.
Artykuł prezentuje nowy dla Polski gatunek grzyba Flammulina ononidis. Gatunek ten został scharakteryzowany pod względem jego cech makro- i mikroskopowych, a także warunków siedliskowych, ze szczególnym uwzględnieniem składu fitocenoz w których wyrastał. Nowe stanowisko grzyba zostało znalezione na wzgórzach kserotermicznych koło Pińczowa w płatach Inuletum ensifoliae iThalictro-Salvietum(klasa Festuco-Brometea), gdzie wyrastał na korzeniach Ononis spinosa. Przedstawiono krótką dyskusję dotyczącą gatunków podobnych oraz ekologii i zagrożeń prezentowanego gatunku grzyba.

Opis:
The Upper Rotliegend deposits of the western part of the Poznań Basin, Poland, represent three main sedimentary environments: aeolian desert (dunes and sand sheets), alluvial plain (alluvial covers with wadi deposits) and marginal playa. In arid periods, dunes prograded into areas dominated by alluvial sedimentation. During wet periods, alluvial deposits eroded the aeolian deposits and prograded onto dune fields. Playa sediments were deposited among aeolian or alluvial sediments during periodic expansions of the playa. These aeolian, alluvial and playa deposits are arranged in depositional sequences. Boundaries between sequences are marked by rapid changes in depositional facies; and by erosional bounding surfaces. Maximum Wetting Surfaces have been distinguished within some parts of the depositional sequences, which enable regional correlations. The sections studied are composed of thick sequences of sand and sand-gravel sheets. The sand sheets represent periods of stratigraphic condensation. Systems of sand sheets are typical of marginal areas of ergs. We distinguish nine depositional complexes (units) numbered 1-9 from base to top, respectively. These subdivisions are based on the interpretation of the sedimentological record in palaeoclimatic terms, and in terms of major erosional boundaries, which are probably of regional extent. In the aeolian deposits, major boundaries are associated with deflation surfaces related to the stabilization of groundwater levels. In the marginal playa deposits, the most important boundaries are correlated to transgressive surfaces that developed during playa expansion. Time gaps represented by the boundaries and the scale of erosion below them, are difficult to estimate. The depositional system of the Upper Rotliegend was dominated by sand and sand-gravel sheets, and is either a unique feature in the entire Southern Permian Basin or, as we assume, sand sheets occur more com monly in the Rotliegend than has been previously thought.

Upper Silesia Coal Basin
Polska
Opis:
The Upper Silesian Coal Basin (USCB) is the largest coal basin in Poland and one of the largest in Europe. It is the most industrialised region in the country. The main natural source of energy is hard coal, which was produced by 65 mines in the early nineties. The USCB geology is very diverse and not homogeneous. Coal deposits situated in the central, southern, and western regions are mostly covered by impermeable Miocene deposits, which helped methane (CH4) to accumulate in the past. Methane is one of the most dangerous natural hazards in Polish underground mining because it is an explosive gas. CH4is also the second strongest greenhouse gas after carbon dioxide, but its radiative power is 20–25 times stronger than the radiative power of CO2. Polish coal mines release 470 thousand Mg (average) of CH4 yearly and it contributes to the greenhouse effect increase. Year after year, Upper Silesian coal mines are going to extract hard coal from deeper seams where the methane content in coal seams is much higher. To keep workers safe, CH4 needs to be captured and released to the open-air atmosphere or used in the power and heat production.
