Opis:

The Late Carboniferous amphibian genus Limnerpeton Fritsch, 1881 is revised on the basis of the type specimens of the eight original species described by Fritsch using material from Nýřany, Třemošná and Kounov, now in the Czech Republic. The type species Limnerpeton modestum is a nomen dubium restricted to a mandible that almost certainly belongs to an amphibamid temnospondyl but is not critically diagnostic. “Limnerpeton” laticeps and “Limnerpeton” macrolepis lectotypes are both small individuals of the same taxon as the later described Mordex calliprepes Steen, 1938 and thus form part of the hypodigm of Mordex laticeps comb. nov. “Limnerpeton” elegans is now Limnogyrinus elegans and is a member of the temnospondyl family Micromelerpetontidae. “Limnerpeton” obtusatum is a specimen of the microsaur Microbrachis pelikani. “Limnerpeton” dubium is an indeterminate tetrapod, probably either a temnospondyl or a pelycosaur. “Limnerpeton” difficile is a nomen dubium but the type is probably a small specimen of the tuditanomorph microsaur Crinodon limnophyes. “Limnerpeton” caducum is almost certainly a specimen of the ophiderpetontid aïstopod Oestocephalus granulosus. Several other described small temnospondyls from Nýřany are discussed and shown to be specimens of either Limnogyrinus elegans, Mordex laticeps or Amphibamidae incertae sedis. The tetrapod fauna at Nýřany includes four dissorophoid temnospondyls as proposed by Milner (1986) but with two changes in nomenclature. They comprise the branchiosaurid Branchiosaurus salamandroides, the micromelerpetontid Limnogyrinus elegans, the amphibamid Platyrhinops cf. lyelli and the primitive trematopid Mordex laticeps. These represent four of the five major dissorophoid families and demonstrate that the group had already diversified by the late Westphalian.

Opis:

Limnogyrinus elegans (Fritsch) is the most primitive micromelerpetontid temnospondyl from the Upper Carboniferous of Nýřany, Czech Republic. Arecent revision of the taxon by Werneburg (1994) attributed to this species a skull in dorsal aspect which was significantly larger than any previously reported and showed evidence of snout elongation. Restudy of this specimen demonstrates it to be a skull, visible in ventral aspect, of a juvenile of Cochleosaurus bohemicus, a more primitive edopoid temnospondyl, which is frequent in the Nýřany assemblage. Werneburg’s diagnosis of Limnogyrinusis revised and the problems of constructing ontogenetic series are discussed.

Opis:

During the last sixty years, large collections of ichthyofauna, mainly isolated, microscopic, skeletal remains (ichthyoliths), from the Middle–Upper Devonian and Lower Carboniferous rocks of southern Poland have accumulated in the hands of Polish palaeontologists and in palaeontological institutions. Some parts of these collections were described in unpublished dissertations and others were published in dispersed papers, dealing mostly with selected regions or taxa. This review summarises the available data from the following regions: the Holy Cross Mountains, the Cracow Upland, the Sudetes and the Lublin Coal Basin (in the latter two cases, single localities). Altogether, 29 chondrichthyan species were identified and a few more still require classification. Of the Sarcopterygii, three species of onychodontiforms and one of the actinistians were found, in addition to a collection of dipnoans that was described much earlier. A few morphological types were distinguished among actinopterygian scales; otherwise the actinopterygian fossils are not referred to any lower-level taxon, and the same applies to the acanthodians. There were several attempts in the past to apply Polish ichthyoliths in biostratigraphy and palaeoecology, but after all these years, it appears that such propositions have only limited significance.

Opis:

New palynostratigraphical data concerning the Carboniferous sedimentary succession of SW Poland has been obtained from the Czerńczyce IG 1 borehole and the Brońsko boreholes on the northern slope of the Wolsztyn-Leszno High, where the oldest rocks were expected. The miospore assemblages recovered from the Czerńczyce IG 1 borehole allowed assignment of the interval studied to the Marsdenian (Namurian B) and Yeadonian (Namurian C). These results, supplemented with previous palynostratigraphical data, refute the existence of a stratigraphic gap between the early Namurian and Duckmantian (Westphalian B). The reinterpretation of the unpublished miospore results of Górecka et al. (2000b, 2001a) from the Carboniferous rocks from the Brońsko boreholes, also indicate that they should actually be assigned to the upper Marsdenian and Yeadonian. All analysed miospore assemblages are mixed and contain abundant reworked specimens. The results above complement previous opinions and permit a re-evaluation of the stratigraphy of the Carboniferous siliciclastic succession of SW Poland. Its sedimentation was certainly initiated in the earliest Namurian or earlier and probably lasted without long gaps until the Stephanian. The abundance and common occurence of reworked miospores indicate the age of rocks eroded during Carboniferous deposition. The lithological and palynofacial features of the late Namurian rocks from the Czerńczyce IG 1 borehole may be interpreted as a record of the shallowing of the sedimentary basin, including the possibility that some of the sedimentation occured in continental conditions. This means that the transition from the deep marine environment to shallow-water or even continental habitats likely had already taken place by the late Namurian. This suggestion, together with the tectonic deformation dated as post-Bolsovian, corresponds to the timing of the deposition and deformation in the German part of the Variscan Foreland Basin.

Opis:

This paper describes in detail palynological data from the Carboniferous siliciclastic rock succession from the Siciny IG 1 and Marcinki IG 1 boreholes (SW Poland), that allow reinterpretation of the local stratigraphy. Two rock series of different ages were recognized. Rocks from the Siciny IG 1 section were assigned to the upper Arnsbergian–Alportian (the Lycospora subtriquetra–Kraeuselisporites ornatus (SO) Biozone) and the Bolsovian (the Torispora securis–Torispora laevigata (SL) Biozone). In the upper part of the Carboniferous section in the Marcinki IG 1 section the upper Arnsbergian–Alportian and Duckmantian interval (the Lycospora subtriquetra–Kraeuselisporites ornatus (SO) and the Microreticulatisporites nobilis–Florinites junior (NJ) biozones respectively) were recognized, although the quality of the palynological data from the latter borehole was generally poor. These results conflict with a Viséan age for these rocks interpreted from fossil marine macrofaunas and indicate the reworked nature of the macrofaunas. Possible means of the macrofaunal reworking, sedimentary environment and thermal history, based on the palynological data, are discussed. Repetition of the stratigraphical succession, probably due totectonic deformation of the rocks in both sections, is demonstrated and indicate a post-Bolsovian age for the deformation event.

Opis:

Many coal seams of varied thickness and aerial extent occur in the Upper Silesia and Lublin basins within Mississippian and Pennsylvanian coal-bearing deposits. Well-documented data on coal quantity in the seams identified allows visualization of their variation within the stratigraphic succession and analysis of the time-dependent coal accumulation process. Some characteristic features of this variation were observed. Coal seams of the Mississippian age (Serpukhovian, Paralic Series), formed within a near-shore environment, most often constitute small resources. There were only two intervals of increased coal accumulation in seams of >100 million tons, in the lower and uppermost parts of the Paralic Series. Within the Pennsylvanian coal-bearing succession of terrestrial fluvio-lacustrine origin, a specific, wave-like pattern of seam resource variations and four intervals of increased coal accumulation are observed. In the Lublin Coal Basin, the Lublin Beds only, deposited during the Late Bashkirian, are coal-bearing, in which a bell-shaped pattern of seam resource variation in the stratigraphic succession is observed. The location of enhanced coal accumulation events in the stratigraphic succession suggests their repetition at ~1–4 My intervals. The characteristic features of the quantitative variation in these coal seams may be correlated with glacial-interglacial and climate humidity changes, and interpreted as a response to variable volcanogenic CO2 supply.

Opis:

Ichnotaxonomic revision of two extended sequences of large tetrapod footprints from the Westphalian A Bochum Formation of western Germany suggests assignment of the specimens to the well−known Permo−Carboniferous ichnogenera Ichniotherium and Dimetropus. Trackway parameters and imprint morphology strongly support basal diadectomorphs and “pelycosaurian”−grade synapsid reptiles, respectively, as the most likely trackmakers. The ichnofossils thereby extend the first appearance of these two important groups of basal tetrapods by about 5–10 million years, to the early Late Carboniferous, which is in accordance with the minimum age for the evolutionary origin of the clades following widely accepted phylogenetic analyses. These trackways provide not only direct evidence bearing on activity and behaviour of large terrestrial tetrapods close to the origin of amniotes, but also serve as a valuable benchmark for the assessment of controversially interpreted vertebrate tracks from other localities of similar age.

The verneuiliid brachiopod Changshunella yangi gen. et sp. nov. is described from the Early Carboniferous Muhua Formation of Guizhou, China. This rather unusual form is characterized by having very small shell dimensions (2.6–4 mm in length), a very high flat procline ventral interarea, and by having three prominent plications on both valves that are arranged in opposed folding; the last feature is characteristic for the family Verneuiliidae. We suggest that the family has been derived from an offshoot of the stock that produced the superfamilies Spiriferoidea, Paeckelmanelloidea, and Brachythyridoidea by developing opposed folding and loss of dental plates or dental adminicula as exemplified by Verneuilia and Changshunella gen. nov.

The Belgian Campine Basin is part of a large paralic north-western coal basin of Carboniferous age, which also extends northwards and eastwards into the Netherlands and Germany. The Westphalian coal-bearing deposits are disconformably covered by Late Palaeozoic or Mesozoic strata and generally show a moderate dip to the north or north-east. An important transpressional fault zone of Palaeozoic age divides the basin into western and eastern sub-basins. During the Carboniferous, syntectonic differences in palaeo-subsidence caused remarkable differences in the burial history and sedimentological styles of these sub-basins and consequently, in their peat and final coal formation, its setting and CBM-potential.Large coal reserves still remain The Belgian Campine Basin is part of a large paralic north-western coal basin of Carboniferous age, which also extends northwards and eastwards into the Netherlands and Germany. The Westphalian coal-bearing deposits are disconformably covered by Late Palaeozoic or Mesozoic strata and generally show a moderate dip to the north or north-east. An important transpressional fault zone of Palaeozoic age divides the basin into western and eastern sub-basins. During the Carboniferous, syntectonic differences in palaeo-subsidence caused remarkable differences in the burial history and sedimentological styles of these sub-basins and consequently, in their peat and final coal formation, its setting and CBM-potential.Large coal reserves still remain in the Campine basin at relatively shallow depths (above 1500 m). Based on the distribution of these coal reserves and their actual rank, an overall CBM-content for the complete basin, as well as for specific anomalous zones within the basin, has been calculated by using an empirically determined (mining) rank / gas relationship. In this manner, six (6) areas have been established in which the gas concentration is significantly (5 times) above a set general threshold value. Together they represent a significant, minimal producible (E)nhanced CBM "target-volume" of about 53 x 109 m3 of methane. The various target areas demand different approaches in any (E)CBM development. In the southern parts of both sub-basins, the remaining changes in porosity/permeability and stress conditions of the rocks, caused by the former mining activities, have to be included into the (E)CBM-development schemes. More towards the north and north-east, any use of preserved coal mining influences is simply not possible. Here, both the sedimentological and structural setting of coals will determine the predominant geologic (E)CBM-development factors.Possibilities for ECBM-production by CO2, N2 or even "raw" flue gases are largely present within or very close to the most prolific CBM-areas. Gas-pipelines and other infrastructure needed for (E)CBM-development are present in the basin, too. The basin is situated within a low to moderately populated part of the country, which is actually rapidly economically expanding. This certifies a steadily increasing gas-consumer market in the next decades.

Opis:

The shallow water assemblage of chondrichthyan microremains, teeth, tooth plates and scales, from the middle Tournaisian (Mississippian) of the vicinity of Muhua village, Guizhou province, southern China, is thus far the richest and most diverse association of this age collected from a single locality and horizon, and represents a chondrichthyan community very restricted in time and space. It was recovered from a small bioclastic limestone lens, MH−1, occurring among basinal marls near the base of the Muhua Formation, and dated as to the Siphonodella crenulata conodont Zone. The majority of the fauna presented here consists of teeth with euselachian−type bases and crushing crowns belonging to bottom−dwelling durophagous chondrichthyans, most probably feeding on shelly invertebrates such as the abundant brachiopods. We assigned most of these teeth to Euselachii (six species, among them Cassisodus margaritae gen. et sp. nov.), Petalodontiformes (two species), Holocephali (five species), and Euchondrocephali incertae sedis (Cristatodens sigmoidalis gen. et sp. nov.). We also identified primitive polycuspid, clutching teeth representing Phoebodontiformes (Thrinacodus bicuspidatus sp. nov.), Symmoriiformes, and Ctenacanthiformes. The scales are typical growing, compound forms of the protacrodont, ctenacanth, and hybodont types. Two problematic denticulated plates were found, one of which resembles mandibular or palatal plates of Sibyrhynchus (Iniopterygii). Several of the identified chondrichthyan taxa have hitherto been known only from Laurussia, especially from the British Isles and central USA. In particular we found the first record of Chondrenchelyssp. and Diclitodus denshumani outside their type locality. Th. bicuspidatus sp. nov., also known from Nevada, Iran, and NW Australia, appears to be a cosmopolitan, middle Tournaisian index fossil.

Opis:

New tergite fragments of Arthropleura were found at the Nowa Ruda mine (Lower Silesia, Poland), after more than seventy years since any previous discovery. The small dimensions of the preserved structures, in terms of the genus Arthropleura, and the characteristic features of tuberculation probably indicate that the remains do not belong to the type species A. armata, but they could represent a new species. The occurrence of round protrusions in the broken-off tubercles is another feature of the new specimens, which has not been mentioned in the earlier literature. Unfortunately, the scanty remains that we have at our disposal (only two specimens were found) are not sufficient for the proposal of a new species. The number of valid Arthropleura species requires further investigation, especially regarding the features, which are diagnostic for species. The tergites described have very numerous tubercles, which may have taxonomic value in species discrimination. Because the fossils were found on a dump, their exact stratigraphic position is not known. However, they occur together with index leaflets of the seed ferns Paripteris gigantea and Linopteris sp., which enabled the age determination of Upper Namurian - Lower Westphalian for the fossils studied. This new discovery of Arthropleura contributes to a better understanding of the genus and of the Carboniferous land fauna of Poland, which is otherwise poorly known. This is also the first, detailed description of Arthropleura remains from the Polish Carboniferous.

Opis:

Six silicified left valves including one nearly complete were obtained from acid residues of two samples collected from the Early Carboniferous Muhua Formation in Guizhou Province, China. The Chinese specimens have reticulate ornament and a large asymmetrical aviculopectinid−type resilifer and are much like Girtypecten from Permian rocks in the United States. However, the Chinese material shows only unicostate radial ornament, whereas Girtypecten is multicostate. Thus, a new taxon Girtypecten (Sinopecten) newelli subgen. et sp. nov. is proposed. The conodont assemblage occurring with G. (Sinopecten) newelli dates the new scallop as Tournaisian (the conodont Lower Siphonodella crenulata Zone); this is the oldest known occurrence of Girtypecten.

Opis:

A zigzag colour pattern with additional collabral belts and irregular spots was observed on a shell of Naticopsis (N.) planispira (Phillips, 1836) found in the Gołonóg Sandstone marine faunal horizon (Namurian A, the Upper Silesian Coal Basin, Poland). A disruption in the colour pattern was also observed to have occurred during ontogenetic shell growth. In this specimen, it appeared in the healed shell damage on the outer lip. So far, only nine Carboniferous species of Naticopsis have been reported with the colour pattern preserved. The most common are the zigzag-type and the spiral band-type. Individual taxa clearly differ in the morphology of the chevrons (direction and angles of breaks) and the location and width of the spiral bands on a whorl. However, the color patterns may not be diagnostic features for the Naticopsis species, because of the large intraspecific variation and colour pattern polymorphism on the neritimorph shells. Colour patterns on Palaeozoic neritimorph shells most likely served as camouflage with respect to the bottom surface in the photic zone.

Opis:

Fifteen bryozoan species belonging to thirteen genera have been identified from an outcrop of the Picos de Europa Formation (Moscovian, Upper Carboniferous) at La Hermida in northern Spain. Three species and one genus are new— Coscinium hermidensissp. nov., Cystodictya pustulosa sp. nov., and Cystocladia hispanica gen. et sp. nov. Rhabdomesid bryozoans are the most diverse order with seven species, followed by cystoporids (four species), fenestellids (three species) and trepostomids (one species). Bryozoans with erect branched or reticulate colonies dominate in the studied assemblage; only two species possess encrusting colonies. Together with associated crinoids, the bryozoan assemblage indicates a subtidal environment below the zone of vigorous water movement. The La Hermida bryozoan fauna confirms the Upper Carboniferous age of the Picos de Europa Formation and allows various biogeographical interpretations. All previously known species of the genus Coscinium were reported from the Lower Permian of Russia. Clausotrypa monticola is known from the Lower Permian of Russia and Arctic as well as from the Upper Carboniferous of Carnic Alps (Austria). Rhabdomeson cf. propatulissimum and Penniretepora pseudotrilineata are known from the same level of Italian Carnic Alps. Streblotrypa (Streblascopora) nikiforovae and Rhombocladia punctata are known from the Upper Carboniferous (Moscovian) of Ukraine. Fistulipora petaloida is known from Kasimovian Stage of Russian Plate. Several other species show connections with North America.

Geological boundaries of the structural stages between Late Variscan Moravian-Silesian-Cracow orogene and Saalian Sławków Graben taphrogene, Early and Late Kimmerian epeirogene, Middle Alpine Silesian-Cracow Monocline, and Late Alpine Carpathian Foredeep are defined as discordances. These structural surfaces of different age, present in the top surface of Carboniferous deposits of the Upper Silesian Coal Basin, were investigated in morphotectonic research. Discordances in the morphotectonical record separate older faulted and folded Carboniferous deposits from younger, nearly subhorizontal rocks of epi-Variscan cover. This polychronic and polygenetic geological heterochronous boundary of the top surface of Carboniferous deposit consists of the following coeval discordances: sub-Permian, sub-Triassic, sub-Jurassic, sub-Cretaceous, sub-Miocene and sub-Quaternary. Those buried erosional surfaces with ancient landforms were some formed by terrestrial, others by marine planation. The repeated erosion of Carboniferous deposits and sedimentation of covers as well as fault, monocline and fold-flexure deformations are reflected in differentiated configuration of discordances in the height range from about 400 m a.s.l. to 6000 m b.s.l.

Opis:

The origin of reptiles in the tetrapod footprint record has always been a debated topic, despite the great potential of fossiliferous ichnosites to shed much light on reptile origins when compared to the much less extensive skeletal record. This is in part due to an unclear ichnotaxonomy of the earliest tracks attributed to reptiles that has resulted in unreliable trackmaker attributions. We comprehensively revise the earliest supposed reptile ichnotaxon, Notalacerta missouriensis, based on a neotype and a selection of well-preserved material from the type locality and other sites. A synapomorphy-based track-trackmaker attribution suggests eureptiles and, more specifically, ́protorothyridids ́ such as Paleothyris as the most probable trackmakers. A revision of the entire Pennsylvanian-Cisuralian record of this ichnotaxon unveils an unexpected abundance and a wide palaeogeographical distribution. The earliest unequivocal occurrence of Notalacerta is in the middle Bashkirian (early Langsettian) at the UNESCO World Heritage Site, Joggins Fossil Cliffs (Joggins, Nova Scotia, Canada). This occurrence also coincides with the earliest occurrence of reptile body fossils (Hylonomus lyelli), which are found at the same site. Notalacerta is abundant and widely distributed during the Bashkirian, mostly in sediments deposited in tidal palaeoenvironments, and less common in the Moscovian and Kasimovian. During the Gzhelian and Asselian, Notalacerta occurrences are unknown, but it occurs again during the Sakmarian and is widespread but not abundant during the Artinskian, mostly in fully continental palaeoenvironments.

Opis:

Five sections from the Kielce Region of the Holy Cross Mountains and one core from a borehole drilled in the nearby western Mesozoic Margin reveal the best recognized beds from the Devonian/Carboniferous boundary interval. In four sections: Ruda Strawczyńska, Bolechowice IG 1, Zaręby IG 2 and Kowala, the Devonian/Carboniferous boundary is located within a continuous series of deep-water carbonates, whereas in the two remaining: Ostrówka Quarry and the Jabłonna IG 1 borehole, the Devonian/Carboniferous boundary interval contains stratigraphic gaps resulting from lack of deposition in submarine conditions. The biostratigraphic position of the analyzed uppermost Devonian and lowermost Carboniferous beds is determined by assemblages of conodonts, microspores and deep-water ostracodes of the Thuringian ecotype. The lithology and biostratigraphic position of particular beds in the Devonian/Carboniferous boundary interval of the Kowala section from the western part of the Holy Cross Mountains resemble those in a succession of equivalent age from the Rhenish Massif. Both areas are characterized by similar lithological horizons and changes of biotic assemblages within the same conodont zones. Strata and fauna from the uppermost Famennian are influenced by the global regressive Hangenberg Event.

Opis:

Carboniferous sandstones and shales encountered in deep boreholes drilled in central Poland, NW of the Holy Cross Mts., represent a pseudoflysch i.e. they show facies features of flysch and, simultaneously, are of cratonic provenance. Clastic sediments were derived from a peripheral bulge formed within the East European Craton as a result of stresses exerted by the accretion/thrust wedge advancing up the marginal part of the craton. In central Poland, NW of the Holy Cross Mts., a Variscan foredeep existed. The foredeep was the depositional site of interfingering exo- and pseudoflysch which, from a geodynamic point of view, are equivalent to an outer molasse. Huge masses of Carboniferous deposits (generally corresponding to flysch) from southwestern and central Poland successively represent, moving from SW to NE, Variscan ortho-, exo- and pseudoflysch.

Opis:

A new species of a non-marine microconchid (Tentaculita) tubeworm, Microconchus hintonensis, from the Lower Carboniferous (Upper Mississippian, Chesterian) of West Virginia, USA, is described. Non-marine microconchids occur abundantly in the deposits of the Bluefield, lower Hinton, Princeton and Bluestone Formations of the Mauch Chunk Group, where they are either associated with land plant remains and bivalve shells, or are preserved loose in the host sediment. The specimens attached to plant remains and bivalve shells, are poorly preserved, but those occurring loose in the deposits are well-preserved in three dimensions. The interpretation pre sented here, is that the loose specimens of Microconchus hintonensis sp. nov. also originally encrusted plants (land plants, algae) and bivalve shells, but became detached after substrate degradation and dissolution. The association of land plant remains, charophyte gyrogonites, bivalves, ostracodes, conchostracans, and fish teeth and scales, and the concomitant lack of strictly marine fossils indicate that the microconchid-bearing deposits of the lower Hinton, Princeton and Bluestone Formations were deposited in fresh-water environments. Microconchus hintonensis sp. nov. is regarded as a highly fecund, opportunistic species that in large numbers colonized every available substrate in its habitat. Its abundance in the deposits investigated indicates that the species was welladapted to the environments it occupied, even during episodes of higher sedimentation rates and/or competition with other soft-bodied encrusters. During such episodes, microconchids were able to grow vertically by uncoiling and elevating their tubes, in order to escape potential burial and/or overgrowth by other encrusters.

Opis:

Obecnie, ze względu na niestabilną sytuację na rynku paliw, jak również z dbałości o środowisko naturalne, obserwuje się wzrost zainteresowania nowymi technologiami (również znanymi, ale niestosowanymi z różnych względów na szerszą skalę) opartymi na wykorzystaniu węgla. Ich stosowanie wymaga szczegółowego rozpoznania budowy pokładów węgla. Taką możliwość, jak się wydaje, stwarza opis pokładów węgla, przy użyciu zmodyfikowanej metodyki standardowo stosowanej analizy mikrolitotypowej. Metoda ta jest również przydatna w badaniach facjalnych pokładów węgla kamiennego. Modyfikacja tej metody badawczej, w celu umożliwienia opisu zmienności mikrolitotypowej w profilu pokładu węgla, polega na 10-krotnym zwiększeniu wymiarów pola siatki 20-punktowej - do wymiarów 500 x 500 [...]. Identyfikowane w trakcie obserwacji mikroskopowych mikrolitotypy umieszczane są w komputerowej bazie danych zgodnie z ich lokalizacją w profilu. Pozwala to na późniejszą interpretację graficzną - wykreślenie profilu mikrolitotypowego.W opisie wyodrębniono 13 asocjacji, w większości zgodnych z powszechnie stosowanymi mikrolitotypami. Zastosowano jednak kilka zmian: w obrębie witrytu wydzielono telo-witryt - zbudowany z telinitu lub kolotelinitu, w profilu makroskopowo widoczny jako warstewki witrynu i detro-żelo-witryt - zbudowany z kolodetrynitu, witrodetrynitu, korpożelinitu i żelinitu, w profilu makroskopowo identyfikowany jako duryn; w obrębie mikrolitotypów bimaceralnych wydzielono witrynertyt (W), witrynertyt (I), klaryt (W), klaryt (I), duryt (L), duryt (I) na podstawie dominującego składnika podanego w nawiasie. Przyjęta metodyka badań umożliwia szczegółową charakterystykę zmienności petrograficznej w profilu pokładu węgla. Pozwala ona w szczególności opisać zmienność w obrębie węgla matowego (durynu), którego odcinki występujące w pokładzie, mimo to, że makroskopowo wyglądają bardo podobnie lub niemal identycznie, mogą mieć bardzo zróżnicowany skład petrograficzny. Największy udział w budowie pokładu ma duroklaryt - 23,8%, nastepnie witryt 18,7% i klaroduryt 17,6%; kilkuprocentowy udział mają witrynertyt (I), witrynertyt (W), inertyt, klaryt (W), witrynertoliptyt, duryt (I), duryt (L); poniżej jednego procenta jest liptytu i klarytu (L). Sekwencja występujących po sobie mikrolitotypów ilustruje również zmienność facjalną, co pozwala na interpretację środowisk depozycji torfu w paleotorfowisku pokładu 116/2. Dominujący udział procentowy w profilu ma facja Forest Moor - 33,5%, a najmniejszy facja Forest Terrestial Moor - 12,5%.
Applying new technologies basing on coal utilization demands precise identification of coal-bed composition. It is suggested, that such possibility is enabled by coal-bed logging with use of - adjusted to this aim - microlithotype analysis. Modification of this research method relies on ten-fold augmentation of 20 point grid size dimensions - up to 500 x 500 [...]. Maceral associations - as identified duringmicroscope observations - are placed in computer database according to their localization in logging. This allows for later graphic interpretation - microlithotype profile drawing. 13 associations has been educed in description, in majority being consistent with commonly used microlithotypes. However, a few changes has been introduced: in description of vitrite, telovitrite, macroscopically recognized in logging as vitrine layers, has been distinguished, as well as detro-gelo-vitrite, macroscopically recognized in logging as durain, while within bimaceralic microlithotypes there has been distinguished: vitrinertite (W), vitrinertite (I), clarite (W), clarite (I), durite (L), durite (I), all on the basis of dominant ingredient named in parenthesis. Accepted research methodology enables precise characteristics of petrographic variation within coal-bed logging. This allows especially to describe variation within dull coal (durain). Basing on research results, it is suggested that the biggest share in seam composition belongs to duroclarite - 23.8%, then vitrite - 18.7% and clarodurite - 17.6%, lower share of few percent belongs to: vitrinertite (I), vitrinertite (W), inertite, clarite (W), vitrinertoliptite, durite (I), durite (L), while both liptite and clarite (L) are less than one percent . Sequence of following microlithotypes also illustrate facies variation, what allows interpretation of environments of peat deposition in paleo-peat bog 116/2. Dominating percentage in log belongs to Forest Moor facies - 33.5%, while the lowest is Forest Terrestial Moor - 12.5%.

Opis:

The fossil record of Paleozoic ophiuroids includes a number of forms which share striking similarities with modern relatives in terms of skeletal morphology. These so called modern-type Paleozoic ophiuroids yield an enormous potential for a better understanding of ophiuroid evolution, yet the scarcity of accurate and sufficiently detailed morphological descriptions available to date precludes any further-reaching assessments. Here, we describe an articulated ophiuroid specimen from the Late Tournaisian (early Carboniferous) of Czatkowice quarry, southern Poland, as a new species Aganaster jagiellonicus sp. nov. The good preservation of the specimen allowed for a morphological analysis at a level comparable to recent ophiuroid descriptions. It shows remarkable morphological similarities with extant former ophio-lepidids Ophiomusium and Ophiosphalma. The new find thus contributes to a solid basis for future investigations on the position of the modern-type Paleozoic ophiuroid in the phylogeny of the class.

Opis:

This study estimates the reservoir properties of the Carboniferous deposits in the southeastern part of the Lublin Basin based on diagenetic and sequence stratigraphic patterns. Depositional sequences distinguished represent the following environments/processes: shallow clay and carbonate shelves, deltaic, fluvial, and hyperconcentrated flow while para-sequences (cyclothems), maximum regression-initial transgression surfaces (T), maximum flooding surfaces (MFS) and also lowstand (LST), transgressive (TST) and highstand (HST) systems tracts have been recognised. Sequences recognized may be linked to the global stratigraphic division of the Carboniferous, thus providing a time framework and environmental context for petrographic and petrophysical examinations. The reservoir properties were found to be clearly controlled by depositional environment, diagenetic history and burial. The best properties were recognized in sandstone lithosomes formed in braided, meandering and anastomosed fluvial channels and hyperconcentrated flows which fill the incised valleys and belong to the LST. They are characterized by good porosity reaching up to 15.1%. The TST and HST deposits are represented chiefly by claystones, mudstones and limestones that formed in a shallow shelf and deltaic environment, being sealing intervals. The diagenetic history of sandstones comprises eo-, meso- and telodiagenetic phases. The major processes acting during the first of these were mechanical compaction, dissolution of mineral grains, formation of predominantly quartz overgrowths around the quartz grains, and crysialiizaton of kaolinite. During mesodiagenesis, cementation with quartz, kaolinite and carbonates continued along with the formation of dickite and fibrous illite; moreover, mineral grains were dissolved and chemical compaction set in. The effects of telodiagenetic processes were feldspar dissolution and precipitation of kaolinite. During diagenesis the maximum temperature affecting the Carboniferous deposits was ~120°C. Compaction and cementation were the main factors responsible for the reduction of porosity by approximately 55 and 38%, respectively. One of the major diagenetic processes was dissolution resulting in the formation of secondary porosity. The Serpukhovian and Bashkirian sandstones from sequence 11 show good reservoir potential, while those from sequences 6, 9, 10, 12-14 only fair potential.

Opis:

The present article concerns a characteristics of enigmatic encrusting organisms of the order Microconchida (microconchids), similar to polychaetes of the genus Spirorbis, as well as a description of their finds from the Upper Carboniferous of the Upper Silesia region, southern Poland. The microconchids described here may represent the genus Microconchus. Most of the individuals encrust terrestrial flora and bivalve shells, and thus they certainly inhabited freshwater or, at most, brackish water environment. Similarly as the Recent polychaetes of the genus Spirorbis, the microconchids described here occur in association composed of both adult and juvenile individuals. The juveniles, however, dominate, what may indicate they have died due to some stress conditions (high rate of deposition and/or low oxygen content in the water). The microconchids are poorly-preserved. The original calcitic mineralogy of their tubes was replaced by phases similar to lead sulfide and dolomite.

The relatively rich assemblages of shark teeth from pelagic limestone (Mississippian, late Viséan, late Asbian-middle Brigantian) of three northern European regions: the Rhenish Mountains (Westenfeld Quarry, Germany), the Holy Cross Mountains (Todowa Grząba at the edge of Ostrówka Quarry, Poland), and Derbyshire (Cawdor Quarry, Matlock, England, UK) display certain similarities, with the absolute predominance of the teeth of Falcatidae (small Symmoriiformes) and the constant presence of Thrinacodus spp. The largest and most diverse assemblage from Todowa Grząba contains at least three species of a falcatid Denaea, a xenacanthimorph Bransonella nebraskensis, a newly described phoebodontid Thrinacodus dziki sp. nov., a few ctenacanthiform and euselachian teeth, and two abraded euchondrocephalan dental elements. Anachronistidae, common in the most of late Viséan pelagic faunas, are absent from Todowa Grząba and Westenfeld. The material under study differs from the shallow-water chondrichthyan fauna, hitherto described from the Mississippian carbonate platform facies, by its taxonomic content (particularly almost total absence of Euchondro-cephali), generally lower diversity, and higher frequency of small teeth.

Five local miospore zones, six subzones and two assemblages are distinguished for the Frasnian to lower Tournaisian deposits in the Kołobrzeg region (western Pomerania): assemblage I, Membrabaculisporis radiatus-Tholisporites densus (RD), Membrabaculisporis radiatus-Cymbosporites boafeticus (RB), Lagenoisporites immensus-Diducites poljessicus (IP) Zone, assemblage II, Tumulispora rarituberculata (Ra) and Convolutispora major (Ma) Zone. The first three biozones and the two assemblages are new in this region. The local miospores zones distinguished in western Pomerania are correlated with the European standard miospore and conodont zonations. Two new miospore species and one new variety are described, two species is emended.

Opis:

Sphenothallus specimens are reported for the first time from the Mississippian of Central Russia. All Sphenothallus specimens have a phosphatic composition and a characteristic laminar structure, which is best observable in the thickened lateral parts of a tube. Most of the lamellae in the tube wall are straight, but some have a wavy morphology and a few are so wrinkled that they form hollow “ribs”. The wrinkled lamellae presumably had an originally higher organic content than the straight lamellae. There are borings on the surfaces of some lamel-lae that are similar in morphology to the bioerosional traces in various hard, biomineral substrates. Lamellae in the inner parts of the tube wall are composed of fibres. The fibres are parallel to the surface of the tube wall and in successive laminae they differ in orientation by irregularly varying angles. It is possible that the plywood micro-structure in Sphenothallus was originally organic and was later phosphatized during fossilization. An alternative, but less likely explanation is that the plywood structure was originally mineralized and therefore is comparable to the phosphatic lamello-fibrillar structures of vertebrates.

Opis:

In this article, the authors describe the characteristics and changes of geomechanical properties of Carbonifeorus claystones as related to their mineral composition and the time of soaking in water. Geomechanical properties, including bulk density, Young modulus, Poisson ratio, unconfined compressive strength, durability index, and swelling index were examined in dry rock samples, and in water-soaked samples after 3 hours of soaking, and 6 hours of soaking respectively. Changes in the geomechanical properties of rocks were also examined as a function of their mineralogical composition. In particular, the properties of rocks were examined in relation to present aluminosilicates and layered aluminosilicates, respectively. Changes in the geomechanical properties were also examined relative to the presence of minerals anatase and siderite. Correlation coefficients between physical parameters and mineral composition were examined. It was determined that the total quantity of aluminosilcates is a better predictor of geomechanical properties after soaking, than only the content of layered aluminosilicates. Calculated correlation coefficients were generally higher for most samples after 6 hours of soaking than after 3 hours of soaking. It was also determined that the increase of bulk density correlates much better with the mineral anatase content, than with the siderite content.

Maturity modelling was carried out using basin and petroleum system modelling (BPSM) software in the lithologic sections of 17 wells of the Upper Silesian Coal Basin (Poland). The best fit between calculated and measured vitrinite reflectance (VR), porosity and density data was obtained by applying a thickness of eroded sedimentary overburden from 1700 m in the east to 4500 m in the west and relatively low to moderate heat flow values during the maximum late Carboniferous burial. These heat flow values were in the range 50-71 mW/m2

Bowmanites brasensis sp. nov. from Břasy (Matylda Mine) and B. pseudoaquensis sp. nov. from Ovčín locality are determined mainly on the basis of their spores, which are about 100 μm in diameter. The thick−walled exine of the miospores is laevigate or sometimes very finely scabrate on the proximal contact area. Spores resemble the dispersed species Punctatisporites obesus. Cones of B. brasensis and B. pseudoaquensis are organically connected with stems having prominent blade leaves and represent a new group of sphenophyllalean strobili.

Opis:

The dispersed miospore assemblage of the Retispora lepidophyta-Verrucosisporites nitidus (LN) Zone from the Holy Cross Mountains(Poland) is marked by enrichment (above 4%) in abnormal spore morphotypes during a terrestrial flora turnover close to the Devonian-Carboniferous boundary, recorded just above the Hangenberg Black Shale level. Incomplete and complete tetrads represent mostly Vallatisporites spp., supplemented by Grandispora, Retusotriletes and Apiculiretusispora. Additional peculiar morphotypes, marked byanomalous overall shape and ornamentation, are interpreted as mutated varieties of Vallatisporites based on intermediate morphologicalstages, connecting them with this well known genus. This relatively high aberrant palynomorph frequency is accompanied by volcanicash intercalations, as well as by charcoal debris and polycyclic aromatic biomarkers indicative of forest wildfire. Thus, the anomalousspore morphology could reflect the mutagenic effect of regional acidification due to explosive volcanism. However, palynological literature data from NW France and Canada highlight the possibility of a supra-regional mutated miospore signal near the Devonian-Carboniferous boundary, and there is need for high-resolution studies of the LN Zone to examine this. The end-Permian scenario of abnormalfloral growth in immensely stressed habitats may therefore apply to other potentially volcanically-induced biotic turnovers.

Opis:

The paper provides new results of palynological studies of rocks from the Świebodzice Unit. An abundant Carboniferous miospores were found in rocks of the Pogorzała Formation from the southern part of this unit. These miospores occur in rocks containing also macrofloral and marine macrofaunal fossils, partly reworked, which were usually considered Upper Devonian. Two miospore sub-assemblages of different ages and colours have been distinguished. One of them consists of poorly preserved miospores, dark in colour, which indicate the Late Visean–Serpukhovian age of the rocks. The other sub-assemblage, found only in a few samples, consists of much lighter and well-preserved miospores of the Asturian age. Their presence is considered as a result of stratigraphical leakage. Observation of the miospore colour indicates that the thermal event occurred after the Late Devonian and before the Asturian and the palaeotemperature exceeded ~180°C. These new data indicate that the geological history of the Świebodzice Unit lasted longer and was much complex than it was previously considered.

Opis:

The main aim of this study is to define precisely the age of the alkaline basalts occurring within the lowermost part of Carboniferous succession in the northeastern part of LublinBasin(drill core Parczew IG-7 and IG-9; SE Poland). The new, whole-rocks 40Ar/39Ar data constrain the age of volcanic activity and emplacement of alkaline basalts to the Late Tournaisian (348 ± 0.8 Ma) with possible prolongation to the Middle Visean (338.5 ± 0.7 Ma). The younger age is however of evidently poorer quality than the older one. The new data caused to correlate the volcanic processes occurring within the Lublin Basin with alkaline intrusions drilled inNE Poland inside the Paleozoic cover of the East European Platform. They also correspond to the volcanoclastic levels defined in different parts of the Trans European Suture Zone in Poland.

Opis:

The Petřkovice Member is the basal unit of the paralic succession of the Ostrava Formation of the Upper Silesian Basin. This member is a valuable source of information about the transition from a marine basin filled with siliciclastic sediments into a paralic basin with the beginning of coal-bearing sedimentation. Models of: (1) the number of coal seams, (2) their total thickness, and (3) the coal content with respect to the total thickness of the succession were created to describe and assess the coal-bearing capacity of the Petřkovice Member. The authors present models for coal seam thicknesses exceeding either 10 or 40 cm. The coal-bearing capacity of the Petřkovice Member is very low. The average share of coal seams thicker than 0.1 m is 3%. The share of coal seams with a thickness that exceeds 0.4 m is only 1.66%. Moreover, in large areas of the basin, in the N and NE parts, the coal-bearing capacity is close to zero, because coal seams of greater thickness were detected only locally there. Based on these models and on other geological data, it is obvious that the onset of coal sedimentation was gradual and limited to particular sites showing the greatest subsidence of the basin floor. In places where minor subsidence took place, there were likely unfavorable conditions for accumulation of organic matter.

Opis:

Arthropod borings are commonly described from pteridophyte and gymnosperm wood in the late Palaeozoic, but they are almost unknown from calamitalean stems. In this paper, a new type of boring in calamital- ean stems from two German localities is reported. These are the mine dumps of Plötz near Halle (Saale), Saale Basin, (Wettin Subformation, Latest Pennsylvanian, Gzhelian, Stephanian C) and the Piesberg quarry near Osnabrück, Subvariscan Foreland Basin, (Osnabrück Formation, Middle Pennsylvanian, latest Moscovian, Asturian/ Westphalian D). Most borings were found in marginal parenchyma of the internodes. They run longitudinally through the pith. The borings are preserved as three-dimensional casts that protrude on the surface of considerably compressed pith casts. This unique preservation of the boring casts required special taphonomic conditions, such as rapid burial coupled with different sediment infilling of the borings and the pith cavity, as well as anoxic conditions to prevent decomposition of the non-resistant parenchyma. Most borings are between 3 to 5 mm wide and contain two classes of invertebrate coprolites: the smaller coprolites are sub-spheroidal in shape and measure (37 to 74) x (37 to 63) pm in diameter. The larger coprolites are also sub-spheroidal and range between (88 to'158) x (68 to 123) pm in diameter. The coprolites, the morphology of the borings, as well as the feeding strategy of the arthropods, suggest that the tunnel system was most likely produced by small millipedes (Myriapoda) and probably also visited by oribatid mites.

Opis:

Normal marine salinity is the main limiting factor for the Subclass Rugosa. Water depth and temperature are less critical. Individual characteristics of specimens and some characteristics of species are, however, excel-lent environmental indicators. Being distributed exclusively by larvae, Rugosa required free distribution by means of marine currents, as well as midway areas suitable for settlement and metamorphosis of the larvae. Not distance but rather geography and midway environments are therefore the limiting factors for their distribution, relationships and stratigraphic value. Siphonodendron and Siphonodendron-like (“Siphonodendron”) corals are discussed as examples of morphoogical similarity, but not necessarily representing a phylogenetic relationship. The known homeomorphy of European and western North American Siphonodendron taxa (Fedorowski & Bamber 2007) may be extended on the European, some southern Chinese and all south-eastern Australian Siphonodendron-like corals, but only the Chinese and SE Australian forms may be truly related. The latter relationship would extend the boundaries of the Early Carboniferous Australian rugose coral province. The Late Tournaisian age of the earliest Australian “siphonodendrons” indicates an ancestry of the coral fauna within the province (SE Australia and S China).A mechanism for north-westward migration of this fauna, from SE Australia to S China, is not clear.
Normalne zasolenie mórz stanowi główny czynnik ograniczający występowanie podgromady Rugosa. Głębokość i temperatura wody są mniej istotne. Tym niemniej, poszczególne cechy okazów i niektóre cechy gatunkowe są doskonałymi wskaźnikami środowiska. Rugosa rozprzestrzeniały się wyłącznie w stadium larwalnym. Kolonizacja nowych obszarów była zatem związana z istnieniem otwartej komunikacji morskiej, odpowiednio ukierunkowanych prądów, a w przypadku długich dystansów również z istnieniem pośrednich obszarów dogodnych dla osiadania i metamorfozy larw. Tak więc nie odległość jako taka, lecz układ lądów i mórz oraz warunki ekologiczne na obszarach pośrednich były czynnikami ograniczającymi dla rozprzestrzenienia, pokrewieństw i wartości stratygraficznej Rugosa. Właściwy rodzaj Siphonodendron i koralowce podobne do tego rodzaju („sifonodendrony”) zostały w tym artykule przedyskutowane jako przykład podobieństwa morfologicznego, ale niekoniecznie pokrewieństw filogenetycznych. Homeomorfia europejskich i północno-amerykańskich taksonów (Fedorowski & Bamber2007) może zostać przeniesiona również na europejskie oraz niektóre chińskie i wszystkie australijskie „sifo-nodendrony”. Tylko gatunki z ostatnich dwóch obszarów mogą być rzeczywiście spokrewnione. Pokrewieństwo to rozszerzyłoby granice wczesnokarbońskiej prowincji australijskiej (SE Australia i S Chiny). Późnoturnejski wiek najstarszych „sifonodendronów” australijskich wskazuje na ich pozycję wyjściową w obrębie prowincji. Mechanizm rozprzestrzeniania się tych faun ku północnemu zachodowi, z SE Australii do S Chin, pozostaje niejasny.

Rozpoznano część profilu, który uległ znacznym, daleko zaawansowanym procesom wietrzeniowym, o czym świadczy występowanie skał słabo zdiagenezowanych i luźnych o nietypowych dla karbonu brązowo-żółtych barwach. Pobrane z analizowanego profilu próbki skał okruchowych zostały poddane badaniom petrograficzno-mineralogicznym. Na ich podstawie stwierdzono, że reprezentują one piaskowce, mułowce oraz iłowce, których jednym z głównych składników jest kwarc. Badany fragment profilu pod względem litostratygraficznym należy do warstw orzeskich reprezentujących górną część serii mułowcowej (moskow).
Orzesze Beds, which recently have been known by one bore hole from the surface, occur in the transition zone between the main saddle and the main basin sediments. The part of profile under the advanced weathering processes has been recognized, as evidenced by the occurrence of poorly diagenetically formed rocks and loose rocks characterized by unusual for Carboniferous brown-yellow colors. Petrographical and mineralogical tests were carried out for the samples from the analyzed profile. On this basis, it was found that they represent sandstones, mudstones and claystones, which mainly contain quartz. The tested fragment of lithostratigraphic profile belongs to Orzesze Beds representing the upper part of mudstone series (Moscovian).

Opis:

The only previous U-Pb zircon date for the the Early Carboniferous flysch sequence of the Moravo-Silesian Paleozoic Basin was published in 1987 from tuffogenic material from Kobylí Quarry at Krásné Loučky near the town of Krnov (Silesia, Czech Republic). The measured age of 319 Ma did not agree with its stratigraphic position, and was used as the basis for a hypothesized block of Late Carboniferous paralic molasse incorporated during a later tectonic event. During a survey of the still active quarry in 2010, volcaniclastic horizons were identified and sampled. Direct correspondence of the tuff units to those sampled in 1987 cannot be proved but is likely. High precision chemical abrasion - thermal ionization mass spectrometry (CA-TIMS) U-Pb dating of zircon from this new material has yielded an age of 340.05 ± 0.22 Ma, which correlates to the previously inferred stratigraphic age of the locality and the current calibration of the Early Carboniferous geologic time scale. The newly established age corresponds to the Visean stage and dates the boundary between the Horní Benešov and Moravice formations that can be correlated with other foredeep basins of the Culm in the European Variscides. A population of detrital Cambro-Ordovician zircons and a single 2.0 Ga old zircon crystal from the same volcaniclastic layer dated by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) are consistent with the known age of source material in the Variscan orogenic front.

Opis:

The position of the Palaeozoic Anthracoptilidae has been a major problem of insect systematics for over a century. The previous hypotheses suggested affinities of Anthracoptilidae with the Palaeodictyopteroida, Protorthoptera, Hypoperlida, stem-Mantodea, Paraneoptera, Holometabola, or Eoblattida. Herein we put forward a new hypothesis based mainly on a comprehensive re-evaluation of the wing venation characters and re-examination of the type material of Anthracoptilus perrieri and Mesoptilus dolloi. The Anthracoptilidae are considered as belonging to the paoliid lineage, sister group of the Dictyoptera. In particular this result refutes the presence of Mantodea in the Paleozoic fossil record. The two families Strephocladidae and Strephoneuridae, are considered as junior synonyms of the Anthracoptilidae, while the previous synonymy of the Anthracoptilidae with the Ischnoneuridae is rejected. We consider the Permarrhaphidae, previously considered as synonym of the Anthracoptilidae, (and Permarrhaphus) as Insecta incertae sedis. The following new taxa are proposed: Mesoptilus carpenteri sp. nov. from the early Permian of Wellington Formation in Oklahoma (USA) which extends the range and distribution of the genus; Pseudomesoptilus gen. nov. is designated to include Mesoptilus sellardsi; Strephocladus permianus sp. nov. from the middle Permian of South of France; Westphaloptilus gallicus gen. et sp. nov. from the Bashkirian of the North of France.

Opis:

A new basal sphenacodontid synapsid, represented by an anterior portion of a mandible, demonstrates for the first time the presence of amniotes in the largest European Permo−Carboniferous basin, the Saar−Nahe Basin. The new taxon, Cryptovenator hirschbergeri gen. et sp. nov., is autapomorphic in the extreme shortness and robustness of the lower jaw, with moderate heterodonty, including the absence of a greatly reduced first tooth and only a slight caniniform development of the second and third teeth. Cryptovenatorshares with Dimetrodon, Sphenacodon, and Ctenospondylus, but notably not with Secodontosaurus, enlarged canines and a characteristic teardrop outline of the marginal teeth in lateral view, possession of a deep symphyseal region, and a strongly concave dorsal margin of the dentary. The new find shows that sphenacodontids were present in the Saar−Nahe Basin by the latest Carboniferous, predating the record of sphenacodontid tracks from slightly younger sediments in this region.

Opis:

In the architecture of Krakow we can find many stones which were quarried mostly from de-posits situated not far from the town. They gave a unique image of present, visible elements in the architecture. Many artists used a marble as the building and decorative stone, in sculptures and sepulchral art. Since XIVth century one of the most popular types of stone, which have been applied in the architecture of Krakow, is the Dębnik “marble”. After polishing, it has a deep black colour and, together with Paczółtowice “marble” has been given the fantastic complement of decorative elements in the monu-ments. In the Krakow we can find a lot of places where both “marbles” have been applied as a decorative elements in the architecture. These stones were forming the cultural heritage of Cracow. Usually they are used in sacred architecture. Dębnik and Paczółtowice “marbles” have been applied in many places, for example at the St Mary's Church and at the Wawel Cathedral, as well at Collegium Maius, St Adalbert’s Church in Market Square or at St Peter and Paul’ Church.

Ambiguous geological position of Carboniferous rhyodacites in the Intra-Sudetic Basin (SW Poland) clarified by SHRIMP zircon ages

Opis:

Rhyodacite sheets (the Sady Górne Rhyodacites) in the lowermost part of the Permo-Carboniferous Intra-Sudetic Basin molasse fill have been mapped as intrusives but, later on, based on ambiguous field and petrographic evidence, reinterpreted as lower Carboniferous lavas and tuffs; if so, they would mark the earliest episode of late-orogenic volcanism in the Intra-Sudetic Basin and in the whole Sudetes region in SW Poland. However, re-examination of field relationships and new observations are consistent with an intrusive emplacement of the rhyodacites as conformable to semiconformable, simple to composite sheets. SHRIMP zircon study indicates that the rhyodacites contain rare inherited zircons of ca. 560 Ma, and ca. 470 Ma (or slightly older), and a main population of zircons with an average concordia age of 306.1 š2.8 Ma. This latter age documents the emplacement of the rhyodacites during a mid/late late Carboniferous (Westphalian) stage of volcanism in the Intra-Sudetic Basin in the Central European Variscides. This post-orogenic volcanism was possibly initiated several million years later than previously assumed, and could have comprised a few pulses over a relatively prolonged time span of millions of years.

Opis:

Zaprezentowano nowe odkrycia dobrze zachowanej flory kopalnej, występującej w obrębie formacji z Glinika (westfal D - stefan B – moskow-kasimow) w depresji śródsudeckiej. Flory kopalne znaleziono w Pstrążnej koło Kudowy Zdroju i Sierpnicach koło Głuszycy Górnej. Na stanowiskach tych oznaczono między innymi fragmenty roślin z klasy: Lycopsida, Sphenopsida, Pteridospermopsida i Cordaitopsida. Odkrycia te pomogą w lepszym stopniu poznać roślinność późnego karbonu w obrębie depresji śródsudeckiej. Szczegółowe badania florystyczne i palinologiczne mogą spowodować konieczność weryfikacji stratygrafii uważanego dotychczas za monotonny zespołu skalnego tworzącego formację z Glinika.
New findings with well preserved fossil of flora have been found in a few places in the Intra-Sudetic Depression, within Glinik Formation (Westphalian D – Stephanian B – moscovian-kasimovian). Fossil of flora were found in Pstrążna near Kudowa Zdrój and Sierpnice near Głuszyca Górna. The assemblage consists of: Lycopsida, Sphenopsida, Pteridospermopsida i Cordaitopsida. These discoveries will help with better understanding of Carboniferous vegetation within Intra-Sudetic Depression. Detailed floristic and palynological investigations should result in more detailed stratigraphic scheme of otherwise monotonous Glinik Formation.
