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.

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.

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.

Opis:

The rugose coral genus Bothrophyllum Trautschold, 1879 is revised on the basis of data from the literature and the author’s personal investigation of both topotypes of its type species B. conicum and related and/or similar taxa from other areas. The intraspecific variability of the type species, its neotype, the intra-generic framework and a new generic diagnosis are established. Many more than 100 taxa related and/or similar to Bothrophyllum were analyzed and the most important of them are discussed. Detailed analysis of the type species based on the neotype and supported by additional topotype specimens illustrated here, allows restriction of both the type species and the genus, and leads to the proposition that Bothrophyllum-like taxa with a shortened cardinal septum should be considered of subgeneric (not named) status. Detailed analysis of the specimens and species described and illustrated from the type site (Myachkovo Quarry, Moscow Basin) form the basis for further considerations. On the basis of that analysis and characters established for the type species, taxa from all other European, African, Asiatic and North American areas either named Bothrophyllum or bearing characters of that genus were analyzed. The supposed origin and discussion of the relationships conclude the paper. A list of synonyms and exclusions from Bothrophyllum and lists of species included, excluded, or possibly belonging to Bothrophyllum and Bothrophyllum-like corals with a shortened cardinal septum are presented.

The corallite identified by him as a second, specifically indeterminate species of Lophophyllum is here questionably included in Amygdalophyllum Dun and Benson, 1920. For the reminding specimens two new, unnamed genera are suggested. ”Lophophyllum” subtortuosum Gorskiy, 1932 belongs to a new, non-dissepimented genus of an unknown family. A possible relationship between gen. nov. 1, sp. nov. 1 and the new Bashkirian genus from the Donets Basin (Ukraine) is proposed.

Opis:

The aim of this study was to investigate the factors, which controlled the lateral change of structural style in the southeastern part of the Lublin Basin (Poland). Five selected seismic reflection profiles were interpreted with a focus on structural interpretation. Along the representative seismic reflection profile, a geological cross-section was constructed and restored. The structural model was supplemented/refined with core analysis to characterize the deformation mode affecting Silurian strata at a sub-seismic scale (i.e. below the seismic vertical resolution). Published palaeothickness maps were used to estimate the pre-deformation thickness of partly eroded Carboniferous rocks. The results of cross-section restoration were then compared to the subsidence modelling carried out for one deep well. The study revealed that during Late Carboniferous shortening, a thick layer of Silurian shales played the role of detachment level, above which brittle Devonian-Carboniferous strata were folded and thrust. The lateral extent of thin-skinned deformation was controlled by the presence of a step in the basement and the pinching out of the Silurian strata. In the northwestern part of the Lublin Basin, the Kock Fault Zone acted as a region of strain concentration, where Silurian shales were tectonically thickened, and shows a ductile style of deformation resembling the mushwad structures of the Appalachian fold-and-thrust belt.

The type collection of the lycopsid cone species Triplosporite brownii Unger was re-examined to assess its in situ spores. The cones are monosporangiate with only microspores that possess both cingulum and zona. They equate to the dispersed miospore genus Lycospora and would be identified as Lycospora cf. pseudoannulata. Therefore, the genus Triplosporite Brown is shown to be a junior synonym to Lepidostrobus and a species emendation is given. A comparison is given with the other Lepidostrobus cones which yielded similar in situ microspores of the Lycospora pellucida Group.

Opis:

This study represents a re-investigation of two historical fossil discoveries, Callibrachion gaudryi (Artinskian of France) and Datheosaurus macrourus (Gzhelian of Poland), that were originally classified as haptodontine-grade sphenacodontians and have been lately treated as nomina dubia. Both taxa are here identified as basal caseasaurs based on their overall proportions as well as dental and osteological characteristics that differentiate them from any other major synapsid subclade. As a result of poor preservation, no distinct autapomorphies can be recognized. However, our detailed investigations of the virtually complete skeletons in the light of recent progress in basal synapsid research allow a novel interpretation of their phylogenetic positions. Datheosaurus might represent an eothyridid or basal caseid. Callibrachion shares some similarities with the more derived North American genus Casea. These new observations on Datheosaurus and Callibrachion provide new insights into the early diversification of caseasaurs, reflecting an evolutionary stage that lacks spatulate teeth and broadened phalanges that are typical for other caseid species. Along with Eocasea, the former ghost lineage to the Late Pennsylvanian origin of Caseasauria is further closed. For the first time, the presence of basal caseasaurs in Europe is documented.

An early Late Tournaisian (Early Carboniferous/Mississippian) ammonoid fauna is described from the Tafilalt of south−eastern Morocco. Twelve genera, four of which are new, and eleven new species are represented: Becanites africanus sp. nov., Triimitoceras epiwocklumeriforme gen. et sp. nov., Irinoceras minutum sp. nov., Muensteroceras quadriconstrictum sp. nov., Eurites bouhamedensis sp. nov., Ouaoufilalites ouaoufilalensis gen. et sp. nov., Helicocyclus fuscus sp. nov., Pericyclus mercatorius sp. nov., Orthocyclus(?) sp., Bouhamedites enigmaticus gen. et sp. nov., Winchelloceras antiatlanteum sp. nov., and Progoniatites maghribensis gen. et sp. nov. Palaeogeographic analysis of Late Tournaisian ammonoid assemblages shows strong endemism at the species−level, but genera and families had a nearly global distribution in the equatorial seas. The new fauna contains the stratigraphically oldest known representatives of the important Carboniferous goniatite families Girtyoceratidae and Goniatitidae.

The revision of shark teeth from the Pennsylvanian black shales of central USA, ascribed to “Phoebodus heslerorum” Williams, 1985 and Symmorium reniforme Cope, 1893, shows that “Ph. heslerorum” is a junior synonym of “Cladodus” divergens Trautschold, 1879. This species belongs neither to Phoebodus nor to Cladodus, so a new genus Heslerodus is proposed. Very common, robust cladodont teeth with a deep labio−basal depression and two buttons, often referred to as S. reniforme, do not belong to the latter species, but to “Cladodus” occidentalis Leidy, 1859. The generic affinity of “C.” occidentalis is yet undetermined, but it is possible that it represents ctenacanthoids.

Early Carboniferous (late Tournaisian) conodonts, recovered from siliceous shales and silicites of the Nyan-Vorga Formation within the Lemva tectonic belt of the Polar Urals (Russia), include the biostratigraphically important taxa Siphonodella lanei, Gnathodus typicus, Dollymae hassi, and Scaliognathus anchoralis, marking the following conodont zones of the upper Tournaisian: crenulata, typicus, and anchoralis. Associated species include representatives of genera Siphonodella, Polygnathus, Pseudopolygnathus, Dollymae, Gnathodus, Kladognathus, and Idioprioniodus. These conodont faunas provide the first biostratigraphically constrained correlations between bathyal deposits of the Lemva Allochthone in the Polar Urals and the “standard” conodont zonation. Ostracodes found in the silicite of the typicus Zone are represented by Sagittibythere ? sp. and Tricornina (Bohemia) sp. The ostracodes are reported from the bathyal deposits of Urals for a first time. The traces of the global Mid-Aikuanian Event are recognized in the upper part of the Tournaisian bathyal succession. This event led to turnover in conodont associations and is followed by increasing in conodont diversity.

The aim of the study was to present the use of archival welllogs for quantitative determination of organic matter (TOC wt.% ). The study was conducted in the lower Palaeozoic rocks of the Baltic Basin and Podlasie-Lublin Basin as well as in the Carboniferous rocks of the Fore-Sudetic Homocline basement. In many wells, sonic logging has not been run at all or run to a limited extent. In such cases, a neural network method was used to estimate the interval time. Then, continuous analysis was carried out for quantitative determination of organic matter content (TOC) using the CARBOLOG method. Finally, well log interpretation was performed for six wells in the Podlasie-Lublin Basin, five wells in the Baltic Basin, and five wells in the Fore-Sudetic Homocline basement. This article presents examples of results obtained for two wells.

Opis:

A new record of the chondrichthyan hybodontoid genus Lissodus is presented from two localities within the Mississippian (Tournaisian) rocks of Ireland. Five morphotypes of the genus are described within each of which occurs morphological variance. Specimens recovered and described herein are from crinoidal limestones whose palaeoenvironments are interpreted as ranging from a moderately shallow high−energy carbonate shelf, to relatively deep off−shore. The richest fauna recovered from the high−energy carbonate shelf, contains all five morphotypes raising the possibility that they may have been derived from a single species of shark. A discussion on the relationship between the five morphotypes and other Carboniferous Lissodus teeth is offered and it is argued that although the morphotypes differ slightly from other Carboniferous Lissodus teeth, they may belong to a closely related species not formally named until additional evidence is obtained. A mouth reconstruction using the teeth recovered from the Lower Carboniferous of Ireland is proposed.

The aim of this paper is to provide the geodynamic evolution and position of the major tectonic elements of the area within the global framework. The Hercynian orogeny was concluded with the collision of Gondwana and Laurussia, whereas the Tethys Ocean formed the embayment between the Eurasian and Gondwanian branches of Pangea. The Mesozoic rifting events resulted in the origin of the oceanic type basins like Meliata and Pieniny along the northern margin of the Tethys. Separation of Eurasia from Gondwana resulted in the formation of the Alboran-Ligurian-Pieniny Ocean as a part of the Pangean breakup tectonic system. During the Late Jurassic-Early Cretaceous time, the Outer Carpathian rift had developed. Latest Cretaceous-earliest Paleocene was the time of the closure of the Pieniny Ocean. Adria-Alcapa terranes continued their northward movement during Eocene-Early Miocene time. Their oblique collision with the North European plate led to the development of the accretionary wedge of Outer Carpathians and foreland basin. The formation of the West Carpathian thrusts was completed by the Miocene time. The thrust front was still progressing eastwards in the Eastern Carpathians.
Dla obszaru wokółkarpackiego skonstruowano 12 map przedstawiających konfigurację płyt litosferycznych, paleogeografię i uproszczony rozkład litofacji w okresie od późnego karbonu po neogen. Przedstawiono ewolucję geodynamiczną tego rejonu na tle ruchu płyt i pozycji głównych elementów tektonicznych w globalnym układzie odniesienia. Orogeneza hercyńska zakończyła się kolizją Gondwany i Laurusji, a Ocean Tetydy utworzył zatokę pomiędzy dwom a ramionami Tetydy - Gondwaną i Laurazją. W wyniku mezozoicznych ryftów wzdłuż północnej krawędzi Oceanu Tetydy powstało szereg basenów typu oceanicznego takich jak Meliata i basen pieniński. Ocean alborańsko-liguryjsko-pieniński powstał w wyniku oddzielenia się Gondwany i Laurazji jako fragment tektonicznego sytemu rozpadu Pangei. W okresie od późnej jury do wczesnej kredy rozwinął się ryft Karpat Zewnętrznych. Na przełomie kredy i paleocenu nastąpiło zamknięcie basenu pienińskiego pasa skałkowego. W okresie od eocenu do wczesnego miocenu terany Adri-Alkapy i Karpat Wewnętrznych kontynuowały ruch w kierunku północnym, a ich kolizja z płytą euroazjatycką doprowadziła do powstania pryzmy akrecyjnej Karpat Zewnętrznych i basenu przedgórskiego. Przy końcu miocenu środkowego uformowały się ostatecznie nasunięcia Karpat Zachodnich, podczas gdy w Karpatach Wschodnich ruchy te przetrwały do końca pliocenu.

Opis:

W pracy zawarto wyniki badania dwóch próbek skrzemieniałego drewna. Próbkę pierwszą pobrano na pustyni w Arabii Saudyjskiej w Al Hawtah, a drugą pobrano na terenie północnych Czech w okolicach Trutnowa. Pierwsza próbka pochodzi z okresu kredowego (formacja z Wasia), a druga jest z okresu karbońskiego. Obydwa okazy poddano obserwacjom makroskopowym oraz mikroskopowym (w świetle przechodzącym i w mikroskopie skaningowym). Przeprowadzono również kilka chemicznych analiz punktowych, a w przypadku próbki pierwszej wykonano analizę rentgenograficzną. W drewnie zmineralizowanym z Arabii Saudyjskiej stwierdzono zanieczyszczenia związkami organicznymi, obecność kalcytu oraz domieszkę minerałów ilastych i kryptokrystaliczny pigment o barwie brunatnej (prawdopodobnie hematyt). Próbka z Czech jest silnie zsilifikowana. Efektem tego procesu jest obserwowany w niej kwarc i chalcedon. Pozwala to na wyciągnięcie wniosku o obecności w niej dwóch generacji krzemionki. I generacja, wcześniejsza, reprezentowana jest przez kwarc; późniejsza II generacja to chalcedon. W przypadku tej próbki również widoczne jest nagromadzenie drobnoziarnistego pigmentu o barwie brunatnoczerwonej na powierzchniach skupień kwarcu bądź chalcedonu.
In this study two samples of silicified wood were examined. One sample was found on a desert in Saudi Arabia, and the second one was taken in the Czech Republic. The first sample represents the Cretaceous period (Wasia), and the second one - Carboniferous. Both specimens were subjected to the macroscopic inspection, microscopic analysis (in the transmitted light and the scanning microscope). Some point analyses were also carried out, and in the case of the first sample the X-ray analysis was made. In the mineralised wood from Saudi Arabia polluting with organic compounds was detected, as well as presence of calcite and admixtures of clay minerals, and cryptocrystalline pigment of dark brown colour (probably haematite). The sample from the Czech Republic (an outcrop near Trutnov) is strongly silicified. The quartz and chalcedony observed in it are effects of this process. This allows for a conclusion about the presence of two generations of the silica in the sample. The first, earlier generation is represented by quartz; and the later, second generation of silica is the chalcedony. In the case of this sample concentration of fine-grained pigment of brown-red colour is also visible on surfaces of quartz or chalcedony.

Opis:

The Family Neokoninckophyllidae and its type genus Neokoninckophyllum Fomichev, 1939 (type species: N. tanaicum Fomichev, 1939) are discussed and emended. In addition, the genera Orygmophyllum Fomichev, 1953 and Yuanophylloides Fomichev, 1953, originally included in the Families Campophyllidae Wedekind, 1922 and Lophophyllidae Grabau, 1928, respectively, are emended as well and transferred to the Neokoninckophyllidae. Two early Bashkirian species, viz. Yuanophylloides rectus (Vassilyuk in Aizenverg et al., 1983) and Y. inauditus (Moore and Jeffords, 1945), and the Moscovian Neokoninckophyllum sp. nov. are described on the basis of new collections from the Donets Basin. Neokoninckophyllum tanaicum, Yuanophylloides gorskyi Fomichev, 1953 (both Moscovian in age) and Y. cruciformis Fomichev, 1953 (latest Bashkirian), are redescribed on the basis of peels taken from Fomichev’s (1953) type specimens. Derivation of the Family Neokoninckophyllidae from the Subfamily Dibunophyllinae Wang, 1950 is postulated and phylogenetic links within the former are hinted at. The occurrence of Yuanophylloides inauditus in both the Donets Basin and the Western Interior Province of North America points to marine communication between those areas during the Bashkirian. The slightly earlier appearance of the oldest neokoninckophyllids in the Donets Basin, in comparison to North America (i.e., R1 vs R2 ammonoid biozones), documents the common roots and monophyletic development of the Neokoninckophyllidae in both areas.

Opis:

The quality of coal has been analyzed basing on the data from geological exploration and chemical - geological analyses of coal carried out on the samples obtained from the boreholes and mining pits. The operated coal seams indexed as 382 and 385/2 reveals the changeable morphology due to the thickness of carbon shoals andstent intergrowths. The other parameters, such as the ash content or the calorific value are strongly linked with the non-coal rock interlayers, which presence causes the decrease in the calorific value and increase in the amount of after-burning ash. These parameters are less dependable on the sedimentation environment of the coal formation material. The content of total sulfur in the analyzed seams does not show any link with the values of the parameters analyzed before. The total sulfur is made up from sulphide gathered in coal and sulphates deriving from the decomposition of plants and supplied by deposit waters in different phases of coal seam formation. The obtained results could be useful in the reconnaissance of the prospective seams lying below the currently exploited ones (e.g. 389) and the seams in the neighboring areas.
Jakość węgla została przeanalizowana na podstawie danych z rozpoznania geologicznego i analiz chemiczno-technologicznych węgla wykonanych na próbach pobranych z otworów wiertniczych oraz wyrobisk górniczych. Eksploatowane pokłady węgla o indeksach 382 i 385/2 wykazują zmienną morfologię ze względu na grubość ławic węglowych oraz występujące w nich przerosty płonne. Węgiel z pokładu 382 posiada następujące parametry: popielność (Ad) - 10,02-38,47 średnio 21,71%, wartość opałowa (Qir) - 18 326-28 089 kJ/kg średnio 23 826 kJ/kg, zawartość siarki całkowitej (Str) - 0,82-2,16% średnio 1,27%, typy węgla - 31.2, 32.1, 32.2, 33. Węgiel z pokładu 385/2 posiada następujące parametry: popielność (Ad)- 6,36-32,32 średnio 18,99%, wartość opałowa (Qir) - 19 881-30 135 kJ/kg średnio 24 661 kJ/kg, zawartość siarki całkowitej (Str) - 0,58-1,83% średnio 0,99%, typy węgla - 32.1, 32.2, 33, 34.1, 34.2. Parametry takie jak popielność czy wartość opałowa są silnie skorelowane z występującymi w pokładzie przerostami skał niewęglowych, których obecność w węglu powoduje obniżenie wartości opałowej i wzrost ilości popiołu po spaleniu węgla. W mniejszym stopniu te parametry będą zależne od środowiska sedymentacji materiału węglotwórczego. Zawartość siarki całkowitej w analizowanych pokładach nie wykazuje związku z wartościami wcześniej analizowanych parametrów. Siarka całkowita stanowi sumę nagromadzonych w węglu siarczków i siarczanów pochodzących z rozkładu materii roślinnej oraz dostarczonych przez wody złożowe na różnych etapach tworzenia się pokładów węgla. Uzyskane wyniki i wnioski dotyczące zmienności parametrów obecnie eksploatowanych pokładów węgla mogą być przydatne przy rozpoznaniu planowanych do eksploatacji niżej leżących pokładów np. 389, 391 lub pokładów w obszarach sąsiednich.

Opis:

Mercury geochemistry is emerging recently as a hot topic in chemostratigraphical and facies research, owing to the diagnostic character of Hg enrichments as a proxy of volcanic activity (crucial in the context of assumed causal links between volcanic cataclysms and mass extinctions). Thus, as a prerequisite to such far-reaching interpretations, reliable analytical determinations of Hg concentrations are necessary. In conventionally performed analyses in sedimentary geochemistry, Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) is usually applied, as an analytical standard for trace elements, including Hg. However, with a detection limit (DL) of 10 ppb, such measured values have been questioned as a conclusive geochemical indicator of Hg anomalies, and, instead, far more accurate techniques, such as Atomic Absorption Spectrometry (AAS; DL = 0.2 ppb), are requested. As a preliminary test of this view, we present comparative analysis of 91 samples from three sections encompassing the key Frasnian-Famennian and Famennian-Tournaisian boundary intervals in Morocco (Lahmida), Germany (Kahlleite) and Uzbekistan (Novchomok), for which Hg concentrations were determined by both methods in the same samples. Despite some differences, especially at low Hg concentrations, both analytical methods reveal the same 12 extraordinarily enriched samples in excess of 1 ppm (with one exception, the determination error is <20%), as well as similar overall chemostratigraphic patterns characterized by a few prominent Hg spikes, with a top value of 5.8 ppm. The Hg concentrations determined by ICP-MS and AAS are significantly correlated, as high as r = 0.98 (Novchomok), even if the first method reveals a general tendency toward slightly heightened values (by ~15 to 30% for medians). Therefore, ICP-MS results can conclusively be used in mercury chemostratigraphy in order to recognize extraordinary volcanic (or other) signals, at least in the Devonian geological record. False Hg anomalies were not generated by these conventional ICP-MS determinations.

Opis:

W profilach otworów wiertniczych Pągów IG 1 i Węgrzynów IG 1 (centralna część masywu małopolskiego) wykonano badania konodontów z utworów węglanowych dewonu i najniższego karbonu. W profilu Węgrzynowa na podstawie konodontów udokumentowano utwory żywetu, franu i famenu datowane na poziomy dolny falsiovalis–górny postera, oraz turneju i wizenu z poziomów delicatus–texanus. W profilu Pągowa na podstawie konodontów udokumentowano fran i famen w zakresie poziomów jamieae–górny rhenana oraz dolny expansa. Niepełna sukcesja poziomów konodontowych w profilach Pągowa i Węgrzynowa wskazuje na obecność luk stratygraficznych. W Pągowie luki stwierdzono w utworach dewonu górnego oraz między utworami dewonu i karbonu, natomiast w Węgrzynowie w utworach z pogranicza dewonu i karbonu. W rejonie Węgrzynowa osady dewonu górnego były deponowane w zbiorniku o znacznie większej subsydencji niż w rejonie Pągowa. Utwory dewonu górnego masywu małopolskiego i obszarów ościennych odpowiadające zbliżonym przedziałom biostratygraficznym są podobne pod względem litologicznym i biofacjalnym.
The conodont study was performed on Devonian and lowermost Carboniferous carbonate rocks from the Pągów IG 1 and Węgrzynów IG 1 boreholes located in the central part of the Małopolska Massif. Based on the conodont biostratigraphy, sediments assigned to the Givetian, Frasnian and Famennian (lower falsiovalis–upper postera zones) and to the Tournaisian and Visean (delicatus–texanus zones) were examined in the Węgrzynów section. The Pągów section is represented by Frasnian and Famennian sediments ascribed to the jamieae–upper rhenana and lower expansa zones. The incomplete conodont zone succession in the Pągów and Węgrzynów sections indicates the presence of stratigraphic gaps. In Pągów, these hiatuses were pinpointed in the Upper Devonian and between the Devonian and the Carboniferous, whereas in Węgrzynów at the Devonian–Carboniferous boundary. In the Węgrzynów area, deposition of the Upper Devonian sediments occurred in a basin, showing much greater subsidence than that in the Pągów area. In the Late Devonian sediments of the Małopolska Massif and neighbouring areas of much the same biostratigraphic intervals are similar in terms of lithologic and biofacies characteristics.

Określono zależności między porowatością i przepuszczalnością oraz wskaźnikiem przepływu FZI w klastycznych utworach karbonu należących do środkowego namuru i dolnego westfalu w basenie lubelskim w rejonie Stężycy. Zaobserwowano zróżnicowanie FZI w poziomach złożowych i w warstwach bez objawów węglowodorów w wydzielonym kompleksie depozycyjnym III oraz w kompleksach III i II. Przeprowadzono analizę statystyczną parametrów petrofizycznych, tj. porowatości, przepuszczalności, objętości piaskowca i iłu w otworach Stężyca 1, 2, 3K i 4 w celu określenia typowych cech dla skał w profilu karbonu, kompleksu III oraz interwału produktywnego w kompleksie III. Wysokie współczynniki korelacji wskazują, że dane są dobrze skorelowane, a porowatość wyznaczona na podstawie badań laboratoryjnych - Poro - może być zastąpiona porowatością PHI, wyznaczoną w wyniku kompleksowej interpretacji profilowań geofizyki otworowej. Wykonano także podziały zbiorów danych wg współczynników FZI i skorelowano porowatość i przepuszczalność w jednorodnych jednostkach przepływu. Relacje określające ruchliwość mediów porowych w jednorodnych jednostkach FZI okazały się silniejsze niż w całym zbiorze. Jako wyniki przeprowadzonych badań przedstawiono także metodę ciągłego wyznaczania współczynnika przepuszczalności in situ na podstawie porowatości PHI
Characteristics of porosity and permeability and Flow Zone Indicator, FZI, of the Carboniferous clastic rocks, especially of the Middle-Namurian Lower-Westfalian in the Stężyca region, Lublin Basin have been presented. There were discovered differences in FZI between the hydrocarbon deposit section and unproductive beds in the determined III complex and between III and II complexes. A statistical analysis was performed for petrophysical parameters, i.e. porosity, permeability, volumes of sand and shale in the wells: Stężyca 1, 2, 3K and 4 to reveal features typical for all Carboniferous data, III complex and hydrocarbon-bearing section of III complex. High correlation coefficients showed data are well correlated and porosity from cores, Poro, can be substituted by porosity from the comprehensive interpretation of logs, PHI. A division of elaborated data sets due to the FZI has been realized and statistical relations between permeability and porosity in homogeneous flow units have been established. Relations describing a mobility of media in pore space for FZI units appeared to be stronger than for the total data set. A method of a continuous K-logging in situ on the base of PHI has also been a result of conducted considerations

Opis:

This paper reviews all available geological data on the Tajno Massif that intruded the Paleoproterozoic crystalline basement of NE Poland (Mazowsze Domain) north of the Teisseyre-Tornquist Zone, on the East European Craton. This massif (and the nearby Ełk and Pisz intrusions) occurs beneath a thick Mesozoic-Cenozoic sedimentary cover. It has first been recognized by geophysical (magnetic and gravity) investigations, then by drilling (12 boreholes down to 1800 m). The main rock types identified (clinopyroxenites, syenites, carbonatites cut by later multiphase volcanic/subvolcanic dykes) allow characterizing this massif as a differentiated ultramafic, alkaline and carbonatite complex, quite comparable to the numerous massifs of the Late Devonian Kola Province of NW Russia. Recent geochronological data (U-Pb on zircon from an albitite and Re-Os on pyrrhotite from a carbonatite) indicate that the massif was emplaced at ~348 Ma (Early Carboniferous). All the rocks, but more specifically the carbonatites, are enriched in Sr, Ba and LREE, like many carbonatites worldwide, but depleted in high field strength elements (Ti, Nb, Ta, Zr). The initial87Sr/86Sr (0.70370 to 0.70380) and ɛNd(t) (+3.3 to +0.7) isotopic compositions of carbonatites plot in the depleted quadrant of the Nd-Sr diagram, close to the “FOcal ZOne” deep mantle domain. The Pb isotopic data (206Pb/204Pb <18.50) do not point to an HIMU (high U/Pb) source. The ranges of C and O stable isotopic compositions of the carbonatites are quite large; some data plot in (or close to) the “Primary Igneous Carbonatite” box, while others extend to much higher, typically crustal ẟ18O and ẟ13C values.

Opis:

The Cracow Sandstone Series (upper Westphalian) forms the uppermost segment of the coal-bearing succession that makes up the bulk of the Variscan foredeep-basin fill in the Upper Silesia Coal Basin. The series, up to 1640 m in stratigraphic thickness, consists entirely of non-marine deposits. Fiveteen lithofacies have been distinguished in the sediments of this series. The Cracow Sandstone Series is subdivided here in two lithofacies associations. The sandstone association consists mainly of medium- to coarse-grained sandstones that form packages up to several tens of metres thick (max. 140 m), with surfaces of erosion at base. These bodies are separated by less voluminous packages of the mudstone association that consists mainly of mudstones and coal seams, which locally make up the predominant part in the sequences of this association. The sediments of the sandstone association are believed to have originated within wide channel tracts of distal sandy braided rivers. The sediments of the mudstone association with the interbedded coal seams are interpreted as floodplain deposits. The predominant type of peat bogs, represented now in the coals of the Cracow Sandstone Series, were wet forest swamps. The peat bogs were probably slightly domed and their margins received clastic material from adjacent channels. This resulted in the frequent lateral splitting of the coal seams. The large-scale splitting of seams is associated with lateral transition of fine-grained floodplain deposits into coarse-grained channel deposits. The vertical alternation of the channel and floodplain deposits is the result of natural processes on an alluvial plain that resulted in shifting positions of depositional environments, first of all avulsion of the whole fluvial tracts. The coal seams in the Cracow Sandstone Series do not form extensive sheets of persistent thickness, and their geometry depends on the course and evolution of the network of fluvial tracts in the alluvial system. The internal geometry of the Cracow Sandstone Series was controlled to a large extent by differential compaction of sediments, notably by rapid compaction of peat.
Krakowska seria piaskowcowa stanowi najwyższą część sukcesji węglonooenej Górnośląskiego Zagłębia Węglowego wypełniającej waryscyjskie, fleksuralne zapadlisko przedgórskie. Seria osiąga 1640 m miąższości stratygraficznej i zbudowana jest wyłącznie z osadów lądowych. W osadach tej serii wyróżniono 15 litofacji oraz dwie, wyraźnie różniące się asocjacje facjalne, określone jako piaskowcowa i mułowcowa. Osady pierwszej z tych asocjacji, złożonej w przewadze z piaskowców średnioziarnistych, dominują w całej serii i z reguły tworzą grube ciała (litosomy),dochodzące nawet do 140 m miąższooeci. Litosomy te rozdzielone są cieńszymi pakietami osadów asocjacji mułowcowej, w których obok osadów klastycznych, z reguły drobnozianistych, pospolicie występują pokłady węgla, nieraz znacznej miąższości. Cała krakowska seria piaskowcowa interpretowana jest jako osady rozległej równiny aluwialnej związanej z systemem piaszczystych, dystalnych rzek roztokowych. W obrębie traktów koryt rzek roztokowych powstawały tam ciała piaszczyste, które zazwyczaj wykazują cechy wielopiętrowych nagromadzeń osadów korytowych. Obszary pozakorytowe były miejscem depozycji materiału drobnoziarnistego i miejscem rozwoju węglotwórczych torfowisk; w pobliżu traktów koryt rozwijały się tam też glify krewasowe. Dominującym typem torfowisk w omawianej serii były wilgotne torfowiska leśne. Pokłady węgla nie mają charakteru ciągłych pokryw o stałej miąższości, a ich geometria i lateralne rozprzestrzenienie zależało od przebiegu i rozwoju sieci traktów systemu rzecznego. Obserwowane zjawiska wielkoskalowego rozszczepiania pokładów węgla i widoczne w tych miejscach lateralne przejścia do osadów korytowych dowodzą współistnienia traktów rzecznych i węglotwórczych torfowisk rozwiniętych na obszarach pozakorytowych Litosomy piaskowcowe mają geometrię pokryw, ale o ograniczonym zasięgu lateralnym. Za stosunkowo dużą stabilnością macierzystych traktów koryt przemawia znaczna miąższość tych litosomów, podobnie jak pospolita, znaczna miąższość pokładów węgla. Naprzemianległe występowanie w profilach pionowych ciał piaskowcowych i ciał reprezentujących osady asocjacji mułowcowej jest wynikiem naturalnych procesów zachodzących na równinie aluwialnej, które powodowały przemieszczanie się środośrodowisk depozycyjnych, głównie procesów awulsji całych traktówkoryt rzecznych. Architektura sedymentacyjna krakowskiej serii piaskowcowej odzwierciedla przede wszystkim efekty wspomnianych procesów, a w dużym stopniu związana jest też ze zróżnicowaną kompakcją osadów gruboziarnistych, drobnoziarnistych i torfów.

Opis:

Sphenacodontid synapsids were major components of early Permian ecosystems. Despite their abundance in the North American part of Pangaea, they are much rarer in Europe. Among the few described European taxa is Neosaurus cynodus, from the La Serre Horst, Eastern France. This species is represented by a single specimen, and its validity has been questioned. A detailed revision of its anatomy shows that sphenacodontids were also present in the Lodève Basin, Southern France. The presence of several synapomorphies of sphenacodontids—including the teardrop-shaped teeth—supports the assignment of the French material to the Sphenacodontidae, but it is too fragmentary for more precise identification. The discovery of sphenacodontids in the Viala Formation of the Lodève Basin provides additional information about their ecological preferences and environment, supporting the supposed semi-arid climate and floodplain setting of this formation. The Viala vertebrate assemblage includes aquatic branchiosaurs and xenacanthids, amphibious eryopoids, and terrestrial diadectids and sphenacodontids. This composition is very close to that of the contemporaneous assemblages of Texas and Oklahoma, once thought to be typical of North American lowland deposits, and thus supports the biogeographic affinities of North American and European continental early Permian ecosystems.

Opis:

A new Late Carboniferous cnemidolestodean insect Xixia huban gen. et sp. nov., is described from the Xiaheyan locality (Zhongwei City, Ningxia, China; Tupo Formation). Its combination of character states and observed variants on the wing venations are indicative of homologies shared with more derived members of the order. In particular it is ascertained that MP runs fused with CuA and CuA + CuPa, but is not usually visible as a distinct vein. The new genus exhibits previously unknown coloration pattern composed of dark patches distributed over the whole forewing (as opposed to regular stripes or rows of spots, previously documented in the group). The comparatively abundant sample makes it one of the best documented cnemidolestodeans to date.

Opis:

The natural mineral resources (hard coal, sands, dolomites, lead and zinc ores) found in the Silesia and the excavation of them led to significant transformation or even degradation of the environment. The landscape of Upper Silesia was dominated by heaps created as a result of the accumulation of post-mining coal waste. These postindustrial sites are characterised by difficult conditions for the development of plant communities. Nevertheless, the heaps are spontaneously overgrowing and over time, a separate ecosystem can be observed (for heaps). The article analyzes the enzymatic activity of the substrate in relation to the selected dominant grass (Monocots) and herbaceous (Dicots) plant species. The aim of this study was to compare the activity of particular enzymes in soil substratum of the vegetation patches dominated by grass and herbaceous plants.

Opis:

The studied area of ca. 500 km2 lies within the Main Anticline and the Bytom-Dąbrowa Trough of the Upper Silesia Coal Basin. During the deposition of the fluvial Zabrze Beds, this area was subject to differential subsidence which resulted in gradual eastward thinning of this unit from ca. 250 m near Zabrze to ca. 4 m near Sosnowiec. Maps of net sandstone and coal contents in two stratigraphical intervals selected within the Zabrze Beds point to the presence of four channel tracts. The main tract is parallel to the NE-SW trending axis of maximum subsidence, and the other three are perpendicular to it. During deposition of the Zabrze Beds the main, NE-SW trending channel tract has shifted westward.

Among the rich material of chondrichthyan microremains from the Indian Cave Sandstone (Upper Pennsylvanian, Gzhelian) near Peru, Nebraska, USA, housed at the Carnegie Museum of Natural History, there occur almost sixty teeth representing Euselachii. They belong to at least seven species, presenting various types of heterodonty. Two new species are described, viz. Ossianodus nebraskensis gen. et sp. nov., whose dentition is similar to that of certain Mesozoic hybodonts, and Sphenacanthus tenuis sp. nov. with minute teeth of protacrodont design. Most of the euselachian teeth served to crush or grind prey, and some had the potential to clutch, but cutting teeth are absent from the fauna.

Opis:

The Indian Cave Sandstone (Upper Pennsylvanian, Gzhelian) from the area of Peru, Nebraska, USA, has yielded numerous isolated chondrichthyan remains and among them teeth and dermal denticles of the Symmoriiformes Zangerl, 1981. Two tooth-based taxa were identified: a falcatid Denaea saltsmani Ginter and Hansen, 2010, and a new species of Stethacanthus Newberry, 1889, S. concavus sp. nov. In addition, there occur a few long, monocuspid tooth-like denticles, similar to those observed in Cobelodus Zangerl, 1973, probably representing the head cover or the spine-brush complex. A review of the available information on the fossil record of Symmoriiformes has revealed that the group existed from the Late Devonian (Famennian) till the end of the Middle Permian (Capitanian).

Opis:

An exceptionally preserved specimen of the extinct trigonotarbid arachnid Eophrynus prestvicii (Arachnida: Trigonotarbida) from the Late Carboniferous (Duckmantian) British Middle Coal Measures of the UK is redescribed with the help of X-ray micro-tomography (XMT). Previous work is summarised and the correct spelling of the species name confirmed. Reconstruction of the void left by the original specimen within a siderite (ironstone) nodule reveals its three-dimensional structure as well as novel details which are difficult to resolve using traditional methods of study. The pedipalps and legs can now be reconstructed almost in their entirety and we can confirm that the chelicerae hung beneath the prosoma with a backwards-directed fang. Opisthosomal segmentation is clarified: a narrow tergite 1 is followed by eight further tergites (2–9), clearly demarked by their ornamentation. In general, a much more accurate picture of the spines and tuberculation ornamenting the dorsal surface of the body was resolved. Ventrally the opisthosoma bears socalled ventral sacs and terminates in a two-segmented pygidium. Based on the XMT model, a new reconstruction of E. prestvicii is presented. Although phylogenetically unrelated, the sometimes similar-looking, spiny and tuberculate lanitorid harvestmen (Opiliones: Lanitores) offer a possible ecological model for these highly ornamented trigonotarbids.

Opis:

The Lower Carboniferous sediments of the Bardo Mts. is mainly composed of biostratigraphically undocumented flysch sequences. A cone impression was found in clayey-mudstone bed of the Srebrna Góra formation that represents one of these flysch sequences. The estimated Middle or even Upper Viséan relative age of this formation was determined based on the underlying paleontologically documented Nowa Wieś formation. The strobilus specimen is morphologically similar to cones assigned to genera Flemingites and Lepidostrobus, that were produced by arborescent lycopsids. The absence of in situ spores makes a precicse taxonomical determination of the cone impossible. The currently known stratigraphical ranges of the two genera are consistent with the previous opinions on the age of Srebrna Góra formation.

Opis:

The teeth of a well known late Palaeozoic cladodont chondrichthyan, “Cladodus” occidentalis from Russia, USA, and England are restudied and a new generic name, Glikmanius gen. nov., is proposed for this species. Yet another tooth−based species, formerly described as ?Symmorium myachkovensis, occurring on the Russian Platform and in Nebraska, is considered to belong to the newly erected genus. Although there is no direct evidence that Glikmanius possessed fin spines, the broad similarity between its teeth and those of Ctenacanthus compressus suggests it had a ctenacanthiform affinity. The possible relationships between Glikmanius, Cladodus sensu stricto, “Ctenacanthus” costellatus, and Heslerodus, are suggested. However, the proposition put forward by an earlier author that the teeth of Heslerodus might represent the lower jaw dentition of G. myachkovensis, is rejected. The overall resemblance of Glikmanius teeth and those of Cladoselache and Squatinactis is recognised as convergent.

Opis:

The paper focuses on the taxonomic description of the lower Carboniferous (uppermost Tournaisian to middle Viséan) solitary rugose corals from bedded limestone and shale units in the Flett Formation in the Jackfish Gap (eastern Liard Range), northwestern Canada. The corals described herein include 12 species representing the genera Ankhelasma Sando, 1961, Bradyphyllum Grabau, 1928, Caninophyllum Lewis, 1929, Cyathaxonia Michelin, 1847, Ekvasophyllum Parks, 1951, EnniskilleniaKabakovich in Soshkina et al., 1962, Vesiculophyllum Easton, 1944 and Zaphrentites Hudson, 1941. Two of these species are new (Ankhelasma canadense sp. nov. and Ekvasophyllum variabilis sp. nov.) and 6 taxa are described in open nomenclature. The distribution and relative abundance of solitary Rugosa in Europe and the Liard Basin confirm the geographical proximity of those areas and the open marine communication between them during the early Carboniferous. It therefore represents an important contribution to the determination of the time of isolation of the western Laurussia shelf fauna from that of southeastern Laurussia, as well as the time of the possible emergence of species from southeastern Laurussia into the western Laurussia seas. Of particular importance here are cosmopolitan taxa and the timing of their disappearance from the fossil record.

Opis:

An uppermost Famennian (Strunian) coral assemblage has been recovered in the middle part of the Yılanlı Formation of the Istanbul Zone (Zonguldak and Bartın areas, NW Turkey). In the Bartın area, the studied fossiliferous interval corresponds to a c. 30 m-thick unit of bioclastic to peloidal wackestone to packstone grading to grainstone and including two stromatoporoid biostromes. In the Zonguldak area, 60 km westward, the bioclastic facies is dominant. The rugose corals are mainly solitary taxa belonging to the genera Campophyllum, Bounophyllum, Amplexocarinia, and ?Metriophyllum, and only one colonial genus occurs: Pseudoendophyllum. This fauna is similar to that documented in Europe. The campophyllids and dibunophyllids are the main component of the uppermost Famennian assemblages in S Belgium, N France, W Germany, NW and S Poland. The endophyllids occur in S Poland, Novaya Zemlya, and in the Ural Mountains. The Istanbul Zone is supposed to be situated in the central part of the Palaeotethys Ocean, along the southern margin of Laurussia during the uppermost Devonian and Carboniferous. The rugose corals indicate some relationship with the eastern part of Laurussia, or that both areas were under a common marine influence at this time. The global Hangenberg event was not recognized in the Turkish localities, except for the disappearance of the corals, occurring less than 19 m below the Devonian–Carboniferous boundary based on the foraminifers. There is no major facies change through the boundary and the first Carboniferous corals (small Uralinia and Caninophyllum) appear 6 m above the D–C boundary. The new species Caninophyllum charli sp. nov. is described from the upper part of the lower Tournaisian.

In order to evaluate usefulness of wastes for utilization it is necessary to use modern chemical testing methods. The proposed analytical system of the XRD-XRF-ICP-GC methods enables to conduct an examination of carboniferous waste rocks. The offered system of chemical testing is less time consuming and much more efficient. Within a reasonably short period of time, it allows to obtain information about mineralogical and chemical properties of the carboniferous waste rocks. In the paper application of such an integrated system has been illustrated with the examples drawn from the monitoring of the carboniferous wastes rocks from the “Bogdanka” coal mine.
Proponowany system badań w zintegrowanym układzie analitycznym XRD-XRF-ICP-GC jest prostym i proekonomicznym elementem działalności w prowadzeniu monitoringu odpadów wydobywczych. Jego wykorzystanie pozwala uzyskać w krótkim czasie informacje o mineralogicznych i chemicznych właściwościach monitorowanych odpadów wydobywczych. Dotyczy to zakresu informacji obejmujących skład mineralny (XRD) i chemiczny (XRF/ICP) oraz obecności zanieczyszczeń organicznych (GC). Wykorzystanie takiego zintegrowanego systemu badań przedstawiono na przykładzie monitoringu odpadów wydobywczych z kopalin węgla kamiennego „Bogdanka”.

Opis:

Osady karbonu występują powszechnie w wielu miejscach Stanów Zjednoczonych Ameryki. Rejon będący przedmiotem porównań to Zachodnia Wirginia, w której liczne wychodnie karbonu zostały szczegółowo udokumentowane florystycznie. Rejon ten leży na zachód od strefy tektonicznej Brewarda - granicy wewnętrznej Appalachów między Płytą Atlantycką a Płytą Centralną. Opracowanie flory karbońskiej tego regionu dokumentuje górny mississip (serpuchow) oraz dolny pensylwan (górny baszkir). Na późny mississip i wczesny pensylwan przypada luka sedymentacyjna, podczas której powstała dokumentowana na terytorium USA tzw. powierzchnia postchesteriańska. Jej odpowiednikiem w polskich zagłębiach węglowych jest luka stratygraficzna sygnalizowana brakiem poziomów goniatytowych H1 i H2. Poniżej tej luki w porównywanych regionach występują utwory morskie i paraliczne z pokładami węgla, natomiast powyżej dominują utwory limniczno-fluwiame z pokładami węgla i pakietami utworów paralicznych.
The Carboniferous deposits occur generally on the entire territory of the United States of America. The region to be correlated is the West Virginia where numerous Carboniferous outcrops occur and they are detailed floristically documented. The studied region is located west of the Breward tectonic zone, the inner boundary of the Appalachian between the Late Palaeozoic Atlantic Plate and the Early Palaeozoic Central Plate. The Carboniferous macroflora documents the Late Mississippian (Serpukhovian/Namurian A) and the Late Pennsylvanian (Late Bashkirian-Early Moscovian). The documented stratigraphic gap the post-Chesterian surface in the studied region corresponds to the latest Mississippian and Early Pennsylvanian. In Polish coal basins it probably corresponds to the stratigraphic gap ascribed to the H1 and H2 goniatite zones. In both studied regions marine and paralic deposits with coal beds occur below the gap and limnic-fluvial deposits with coal beds and thick paralic deposits dominate just above it.

Opis:

System naftowy karbon–czerwony spągowiec w niemiecko-holenderskiej części basenu wykazuje szereg podobieństw i różnic w stosunku do polskiej części basenu. Głębokości występowania złóż gazu w niemiecko-holenderskiej części basenu są większe (1000–5300 m) niż w polskiej (1000–3700 m) i do 4000 m w strefach gazu zamkniętego (tight gas). Gazy wykazują duże zróżnicowanie składu chemicznego, jak i parametrów fizycznych. Średnia zawartość metanu w niemiecko-holenderskiej części basenu waha się w przedziale 30–95%, rosnąc szybko w kierunku zachodnim, natomiast w polskiej części basenu wynosi od około kilkunastu do około 90%, wykazując jednak duże zróżnicowanie w poszczególnych strefach. Gazy zakumulowane głównie w czerwonym spągowcu były wygenerowane przez skały macierzyste karbonu górnego (głównie pokłady westfalskich węgli kamiennych) w niemiecko-holenderskiej części basenu, a podrzędnie jedynie przez dolnokarbońskie skały. Basen niemiecko-holenderski był rozcięty przez liczne mezozoiczne uskoki, które przyczyniły się do powstania szeregu zrębów i rowów tektonicznych. Spowodowało to w efekcie zróżnicowanie głębokości pogrążenia i czasu występowania procesów generowania, migracji i akumulacji gazu, oraz zróżnicowanie szeregu pokarbońskich skał zbiornikowych i uszczelniających. Procesy generowania migracji i akumulacji gazów przebiegały wieloetapowo: od późnego karbonu aż do neogenu włącznie.
Carboniferous-Rotliegend Petroleum System in the German-Dutch part of the South Permian basin shows a number of similarities and differences in relation to the Polish part of the basin. Depth of occurrence of gas deposits in the German-Dutch part of the basin are larger (~1000–5300 m) than in Poland (~1000–3700 m) with the maximum of up to 4000 m in the tight gas zone. Gases show significant variation of chemical composition and physical parameters. The average methane content in the German-Dutch part of the basin ranges from 30 to 95% rising rapidly towards the west, whilst in the Polish part, the average methane content varies significantly in different areas of the basin (from several up to 90%). Gases that accumulated mainly in the Rotliegend, were generated predominantly by Westphalian source rocks (bituminous coals) in the German-Dutch part of the basin, and only subordinately by Lower Carboniferous source rocks. German-Dutch basin was dissected by numerous Mesozoic faults, associated with horsts, grabens, and platforms. It contributed to the differentiation of burial depth and timing of the generation processes, to the migration and accumulation of gas, and to the diversification of a number of post-Carboniferous reservoir rocks and seals. The processes of gas generation, migration and accumulation included several stages: from Late Carboniferous through Neogene.

Opis:

Three mafic-alkaline intrusive bodies in NE Poland: Ełk, Pisz and Tajno, have been dated recently with U-Pb SHRIMP method. An earlier Rb-Sr whole rock isochron of Ełk syenites pointed to an age 355š4 Ma, while K-Ar age estimates suggested a Late Paleozoic age of Pisz and Tajno rocks, however, in a wide range between 349-291 Ma and 327-289 Ma, respectively. In the paper, we present new geochronological results and discuss the problem of the closure temperatures for different minerals and different isotopic systems used in previous age determinations. Much of the early dating works has been done using K-Ar method. Biotite and K-feldspar retain radiogenic Ar quantitatively below 280 -200şC. Only if magmatic bodies cooled quickly and remained unmetamorphosed, K-Ar and Rb-Sr ages estimate accurately the intrusion emplacement. Zircon used for U-Pb datings has a closure temperature over 800şC, that is comparable to the temperature of magma’s solidus. Therefore U-Pb magmatic zircons dates could be interpreted as an intrusion emplacement ages. The obtained U-Pb results of 347.7 š8 Ma (Ełk) and 345.5š5 Ma (Pisz) have shown very consistent Early Carboniferous age of platform mafic-alkaline magmatic activity. This new U-Pb SHRIMP dating indicates that Ełk and Pisz intrusions are coeval and together with the Tajno alkaline-carbonatite massif could be affined with the Late Devonian Kola Alkaline Carbonatite Province (KACP).

Opis:

In the Lublin region Carboniferous sandstones are represented by subarkosic, quartz and sublithic, occasionally arkosic arenites and wackes. These rocks are characterized by porosity (primary and secondary) ranging from 0 to 22.43% and permeability from 0 to over 1000 mD. Two diagenetic processes, that is compaction and cementation, were primarily responsible for reduction of porosity in these sandstones. The compaction decreased porosity at about 50%, while the cementation at 30%. Quartz, kaolinite and carbonates and locally fibrous illite are the most common cements here. Dissolution is also important as a diagenetic process responsible for development of secondary porosity. Good porosity of the bulk of Carboniferous sandstones is due to precipitation of early overgrowth cements (quartz, Fe-chlorite and siderite), which stopped the mechanical compaction, and dissolution of feldspar grains and authigenic quartz leading to origin of secondary porosity. The processes of mechanical compaction and advanced quartz and carbonate cementation (mainly of the ankerite and Fe-calcite type) as well as crystallization of fibrous illite were the major factors responsible for reduction of porosity in some sandstones. The results of the studies on pore space indicate good reservoir properties of sandstones of the Lublin and Dęblin formations as well as some parts of the Terebin formation. The sandstones from the Huczwa formation and a part of the Terebin formation belong to rocks characterized by low petrophysical parameters. Comparisons of sandstones formed in different environments have shown that best reservoir conditions are displayed by these formed in river channel and delta bottom ennvironments. During diagenesis, the Carboniferous deposits remained under influence of the maximum temperature of about 120oC, but locally the temperatures could have been even higher. Maximum temperatures were reached by the Carboniferous deposits at the end of Carboniferous whereas diagenetic proccesses were active until early Permian. The results of studies on diagenesis of these rocks, projected onto the thermal-erosional model, point to the Variscan overheating.

Opis:

Fining-upwards cyclothems found in five boreholes in the Carboniferous (Lower Bashkirian) of the Lublin Basin were analysed sedimentologically. It was established that the cyclothems represent fluvial deposits, and the lithofacies were grouped into lithofacies associations. Most lithofacies associations represent three types of sand-bed braided rivers: (1) high-energy, (2) deep and (3) distal sheetflood-affected. Other associations represent hyperconcentrated flows. Both coarse-grained (type I) and fine-grained (types IIa and IIb) occur among the fining-upward cyclothems. The formation of most thick cyclothems was related mainly to allocyclic factors, i.e. a decrease in the river’s gradient. The thickest fining-upward cyclothems are characteristic of hyperconcentrated flows and braided-river channels. The aggradation ratios were commonly high. During the early Namurian C and early Westphalian A (Early Bashkirian), the eastern part of the Lublin Basin was located close to the source area. The sedimentary succession developed due to a transition from high-energy braided-rivers and hyperconcentrated flows to lower-energy braided rivers, controlled by a rise of the regional base level.

Opis:

The extinct arachnid order Trigonotarbida Petrunkevitch, 1949 is reported here for the first time from Ukraine. The material consists of an opisthosoma preserved in ventral view from the upper Carboniferous (lower Moscovian; Paralegoceras–Eowellerites ammonoid zone) of the Gorlivka locality in the Donets Basin, eastern Ukraine. Formal assignment to a family or genus is difficult, but the preserved ventral anatomy is consistent with a member of the families Aphantomartidae Petrunkevitch, 1945, Kreischeriidae Haase, 1890 or Eophrynidae Karsch, 1882. It is noteworthy for expanding the known distribution of trigonotarbids in Europe and is only the second Palaeozoic arachnid to be formally described from Ukraine; the other being the carapace of a whip scorpion (Thelyphonida Latreille, 1804) from Lomovatka in the Luhansk Region, also in the Donets Basin.

Opis:

Minerały ilaste należą do głównych składników spoiwa piaskowców karbonu w basenie lubelskim. Wśród nich wyróżniono minerały allogeniczne wchodzące w skład matriksu oraz minerały autigeniczne tworzące cementy. W pracy wykorzystano następujące metody badawcze: mikroskop polaryzacyjny, katodoluminescencję, skaningowy mikroskop elektronowy, analizę rentgenograficzną, badania spektroskopowe w podczerwieni oraz oznaczenia izotopowe wieku K/Ar diagenetycznego illitu. Głównymi autigenicznymi minerałami ilastymi w piaskowcach karbonu są minerały podgrupy kaolinitu – robakowaty kaolinit oraz blokowe: kaolinit i dickit. W mniejszej ilości występują: illit włóknisty, chloryty oraz minerał mieszanopakietowy illit/smektyt. W eodiagenezie krystalizowały kaolinit robakowaty i chloryty w obwódkach. W mezodiagenezie w temperaturze powyżej 50°C tworzyły się blokowy kaolinit i dickit, minerał mieszanopakietowy illit/smektyt oraz illit włóknisty. Transformacja kaolinitu w dickit wskazuje na temperaturę około 120°C. Oznaczenie wieku K-Ar krystalizacji diagenetycznego illitu – około 260 mln lat – sugeruje, że osady karbonu osiągnęły maksymalne temperatury około 160°C we wczesnym permie.
Clay minerals are the main components of the Carboniferous sandstones cement in the Lublin Basin. The allogenic minerals included in the matrix and authigenic minerals forming cements were distinguished among clay minerals. The following research methods were used in the paper: polarizing microscope, cathodoluminescence, scanning electron microscope, X-ray diffraction analyses, infrared studies and isotopic age K-Ar of diagenetic illite. The main authigenic clay minerals in the Carboniferous sandstones are kaolinite subgroup minerals – vermiform kaolinite and blocky kaolinite and dickite. In a smaller amounts are: fibrous illite, chlorites and illite/smectite mixed-layered mineral. Vermiform kaolinite and chlorite rims were crystallized in eodiagenesis. Blocky kaolinite and dickite, illite/smectite mixed-layered minerals and fibrous illite were formed above 50°C in mezodiagenesis. The transformation of kaolinite to dickite indicates the temperature at about 120°C. Determination of the K-Ar age of crystallization of the diagenetic illite – about 260 My ago suggests that the Carboniferous deposits have reached the maximum temperature of about 160°C in the Early Permian.

Opis:

The types of the species belonging to the fusulinid genera Schubertella and Eoschubertella were examined from publications and type collections. Eoschubertella in general possesses all the features of Schubertella and therefore is a junior synonym of the latter. However, the concept of Eoschubertella best describes the genus Schubertina with its type species Schubertina curculi. Schubertina is closely related to the newly established genus Grovesella the concept of which is emended in this paper. Besides Schubertella, Schubertina, and Grovesella, the genera Mesoschubertella, Biwaella are reviewed and three new species, Grovesella nevadensis, Biwaella zhikalyaki, and Biwaella poletaevi, are described. The phylogenetic relationships of all Pennsylvanian–Cisuralian schubertellids are also proposed. Barrel−shaped Grovesella suggested being the very first schubertellid that appears sometimes in the middle–late Bashkirian time. In late Bashkirian it is then developed into ovoid to fusiform Schubertina. The latter genus gave rise into Schubertella in early Moscovian. First Fusiella derived from Schubertella in late Moscovian, Biwaella—in early Gzhelian and Boultonia—in late Gzhelian time. Genus Mesoschubertella also developed from Schubertella at least in Artinskian, but may be in late Sakmarian.

The cameral and intrasiphonal deposits of a Pennsylvanian straight nautiloid (Pseudorthoceratidae) are studied in order to understand the formation of these deposits. The specimens from the Buckhorn Asphalt deposit (Oklahoma) are exceptionally preserved including original aragonite and microstructures. The specimen investigated survived a predation attempt and shows bite marks on the phragmocone. This is the second report of an ectocochleate cephalopod and first report of an orthoconic nautiloid which survived massive damage of conch and siphuncle. For the first time, a high−magnesium calcitic mineralogy of cameral deposits is documented. These deposits were formed in alternation with aragonite in a chamber which was perforated during the unsuccessful predation attempt. The animal formed the chamber deposits throughout its entire lifetime and the siphuncle played a major role in formation of the cameral deposits.

Opis:

Specimens of the microscopic teeth of the chondrichthyan genus Thrinacodus are described from Mississippian (Tournaisian) rocks of Ireland. They are from calcareous mudstones or crinoidal limestones whose palaeoenvironments are interpreted as ranging from near shore, shallow water through moderately shallow high energy carbonate shelf, to relatively deep off−shore. The richest fauna was recovered from the high−energy carbonate shelf, containing both asymmetrical and symmetrical teeth raising the possibility that they may have been derived from a single species of shark. The teeth are assigned to Thrinacodus incurvus (Newberry and Worthen, 1866), which is suggested to be a senior synonym of Thrinacodus ferox Turner, 1982. Presently the genus is known only from isolated teeth. The asymmetrical and symmetrical teeth are described as two morphotypes, ferox morphotype and nanus morphotype. Within the morphotypes, morphological variation occurs, especially within the ferox morphotype, allowing a number of possible reconstructions of the dentition of Thrinacodus incurvus to be presented as a basis for future debate.

Opis:

The paper presents the characteristics of prospective zones identified for the first time within the lower Palaeozoic shale formations occurring in the Baltic-Podlasie-Lublin Basin and within the Carboniferous shale, sandstone, and mixed shale-sandstone complexes (the so-called hybrid complexes) in the basin of south-western Poland. The lateral and vertical ranges of these zones are determined based on specific criteria using the results of various research methods and analyses, i.e.: stratigraphic, sedimentological, mineralogical, petrological and geochemical of organic matter, petrographic and petrophysical, including interpretation of well logs. Archived geological materials and those coming from the boreholes drilled recently in the concession areas were also used. Four prospective zones have been distinguished in the lower Palaeozoic of the so-called shale belt: SP1, SP2, SP3 and SP4. The most prospective area for the occurrence of unconventional hydrocarbon deposits in shale formations is the Baltic region – the Łeba Elevation, where there are all four perspective zones, only partially covering the range of potentially prospective formations. In each of these zones, both liquid and gas hydrocarbons can be expected in this area. Due to the low percentage of organic matter, the lowest hydrocarbon generation potential is attributed to the Lublin region. However, the low values of this parameter are compensated by other parameters, i.e. the considerable thickness and lateral extent of zone SP4 corresponding partly to the Pelplin Formation. In the Carboniferous rocks of south-western Poland, seven prospective zones have been distinguished in four borehole sections. Four of them are “tight” zones in compact sandstones, while the other three zones represent a hybrid type in complexes with mixed lithology. No prospective zones have been defined in complexes with homogeneous shale lithologies. Determination of lateral extents of the identified zones has not been possible due to the scarcity of data on the geological structure and stratigraphy of the Carboniferous succession in the study area

Opis:

Stan rozpoznania jakości węgla w Lubelskim Zagłębiu Węglowym (LZW) jest odzwierciedleniem rozpoznania geologicznego złóż węgla zlokalizowanych głównie w centralnej części zagłębia. Analizie jakościowej i technologicznej poddano próbki węgla pobrane z pokładów przewierconych w ponad 500 otworach wiertniczych. Zdecydowana większość utworów pochodzi z formacji z Lublina, w której występuje podstawowe, wielopokładowe złoże węgla. Węgiel z formacji starszych, ze względu na brak pokładów bilansowych jest słabiej rozpoznany, ale wyniki przeprowadzonych badań są wystarczające do oceny jakości węgla w całym zagłębiu. Jakość węgla oceniono na podstawie następujących parametrów: Wa, Qsdaf, Hdaf, Cdaf, Vdaf i RI. Wymienione parametry wykazują pewne prawidłowości rozkładu w otworach. Prawidłowości te pozwoliły wydzielić trzy strefy metamorfizmu z : węglem płomiennym typu 31, gazowo-płomiennym typu 32 i gazowo-koksowym typu 34. Brakuje podstaw do wydzielenia węgla gazowego typu 33 i ortokoksowego typu 35. Węgiel typu 31 występuje od stropu karbonu tylko w północnej części LZW, węgiel typu 32 – w centralnej części, a typ 34 dominuje w części południowej. Powierzchnie ograniczające wymienione strefy są niezgodne z powierzchniami stratygraficznymi, a także z poziomami głębokościowymi w odniesieniu do poziomu morza. Parametry technologiczne oceniono na podstawie zawartości: popiołu, siarki całkowitej oraz wartości opałowej. W LZW występuje węgiel nisko- (średnio około 10,5% popiołu) i wysokopopiołowy (średnio >25,0% popiołu). Zawartość popiołu ma decydujący wpływ na wartość opałową. Zawartość siarki całkowitej w węglu pokładów bilansowych tylko lokalnie przekracza 2,0%, ale w pokładach cienkich poniżej formacji z Lublina zawartość siarki często przekracza 5,0%, osiągając wartości maksymalne powyżej 13,0%.
The state of knowledge of the Lublin Coal Basin’s coal quality reflects the geological exploration level of the coal deposits located within the central part of the Basin. The coal samples, collected from the coal seams encountered in over 500 boreholes, underwent qualitative and technological analyses. Majority of the samples has been taken from the Lublin Formation that contains the most important, multi-seamed coal deposit. Coals from the older formations are much less recognised, as their coal seams have no economic value. However, the existing analytical results are sufficient to assess the coal quality of the whole Basin. The coal quality has been assessed based on the following parameters: Wa, Qsdaf, Hdaf, Cdaf, Vdaf i RI. The above mentioned parameters reveal some distribution regularities within the boreholes. Those regularities allowed to distinguish three zones of the coals metamorphism: flame coals of the 31 type, flame-gaseous coals of the 32 type, and coking-gaseous coals of the 34 type. There is no data, however, allowing to determine gaseous coals of the 33 type and/or ortho-coking coals of the 35 type. Coals of the 31 type occur in the northern part of the Lublin Coal Basin, only. Coals of the 32 type occur in its central part, and coals of the 34 type dominate in its southern part. The surfaces limiting the above mentioned zones are lying unconformably to the stratigraphic surfaces as well as to the depth levels measured from the sea level. The coals technological parameters have been assessed based on the ash and total sulphur content, and on the coals’ net calorific values. In the Lublin Coal Basin occur low-ash (10.5% in average) and high-ash (>25.0% in average) coals. The ash content is crucial as far as the coals’ net calorific values are concerned. The total sulphur content of the coal seams with the economic thickness exceeds 2,0% locally, only. However, the total sulphur content of the thinner coal seams, occurring below the Lublin Formation, exceeds very often 5,0%, reaching even 13,0%, maximally.

Opis:

This paper describes 37 species (4 new) belonging to 27 genera (1 new), 14 families, and 6 orders (Lingulida, Craniida, Strophomenida, Productida, Orthotetida, and Orthida) of silicified brachiopods from the middle Tournaisian (Mississippian, lower Carboniferous) of the vicinity of Gedongguan and Muhua villages (southern China). All specimens come from acid etching of detrital and oolitic limestone lenses scattered within grey to black laminated basinal micrite and marl of the Muhua Formation. The formation, which attains about 1–10 meters in thickness, is dated to the Siphonodella crenulata Zone. More than 10,000 silicified brachiopod specimens belonging to about 70 species were recovered from over 900 kg of the sampled limestone lenses, the most diverse brachiopod fauna of that age. The characteristic feature of the studied material is the prevailing disarticulation and fragmentation of skeletal parts due to their down slope transportation into a deeper water environment. Within Lingulida, one linguloid and one discinoid species are described. Craniida are represented by five species including Nematocrania pilea sp. nov. Strophomenida are represented by fragmentarily preserved specimens belonging to one species. The most diverse are Productida, which are represented by 7 chonetidine and 12 productidine species; new are Subglobosochonetes gedongguanensis sp. nov. and Globosochonetes gracilis sp. nov. New data on morphology of larval stage of Argentiproductus margaritaceus and its mode of attachment are presented. Orthotetida is represented by 5 species including Lamellispina spinosa gen. et sp. nov. Orthida is represented by 3, mostly cosmopolitan species. This study of a middle Tournaisian brachiopod fauna from Muhua, together with published data on the Mississippian brachiopods from other regions of South China, allow to study the Devonian–Carboniferous biotic crisis and post−crisis recovery.

Opis:

The epidermal anatomy of Pseudoctenis samchokense is described revealing non−bennettitalean characters of these leaves from the Permo−Carboniferous of China (and Korea). The specimens were originally described as Pterophyllum samchokense suggesting a bennettitalean affinity. They can no longer be considered bennettitalean since their cuticles lack the distinctive brachyparacytic stomata of that clade. Pterophyllum was originally erected as a morphogenus for segmented leaves from the Mesozoic and has subsequently been clearly assigned to the Bennettitales. The segmented leaves from the Permo−Carboniferous of Shanxi and Hebei, China described herein require a new ordinal and generic assignment since the non−bennettitalean cuticular characters documented reinforce the uncertainties in attribution of any foliage older than Late Triassic to the Bennettitales. Based on leaf−architecture and epidermal anatomical characters, the specimens are at best assigned to the cycadalean genus Pseudoctenis. This genus was formerly known only from Mesozoic rocks. Consequently, the specimens are highly significant, as they are among the oldest known vegetative remains of cycads. Re−evaluation of the affinities of all specimens assigned to Pterophyllum from Palaeozoic rocks is thus essential. Based on a review of other Permian–Carboniferous fossil leaves assigned to Pterophyllum, we conclude that none yet reveals definitive bennettitalean characters.

Opis:

This paper presents geochemical data for 171 core samples of the Carboniferous coal-bearing series and the Miocene cove from the central part of the Upper Silesian Coal Basin. Major oxide concentrations (Al2O3, SiO2, Fe2O3, P2O5, K2O, MgO, CaO, Na2O, K2O, MnO, TiO2, and Cr2O3) were obtained using XRF. Trace and major elements (Mo, Cu, Pb, Zn, Ni, Co, U, Cr, V, Mn, As, Th, Sr, Cd, Sb, Bi, Ba, Ti, W, Zr, Ce, Nb, Ta, Be Sc) were analysed ICP-MS. The main goals of this study were to demonstrate the distribution, as well as the stratigraphical variability, of the selected elements and to determine whether chemostratigraphy tools could be effectively applied to analyze Carboniferous and Miocene deposits of the USCB. Geochemical studies have shown showed different geochemical features of the samples from the Carboniferous and the Miocene. The diversity is mainly expressed in the enrichment of Miocene sediments in Ca and Sr related to biogenic carbonate material. It was also stated that the concentrations of trace elements associated with the detrital fraction, such as Zn, Cr, Co, Ba, Ti, Zr, Nb, and Sc show slightly higher values in Carboniferous sediments. On the basis of the content of Ti, Zr, and Nb, as well as ratios such as Th/U, Zr/Th, Ti/Zr, and TiO2/K2O, units with different inputs of the terrigenous fraction can be identified in both Carboniferous and Miocene formations. The paper shows that chemostratigraphy can be used as a stratigraphic and correlation tool for the Carboniferous and the Miocene deposits of the USCB.
W pracy przedstawiono dane geochemiczne dla 171 próbek skał osadowych z karbońskiej serii węglonośnej i pokrywy mioceńskiej z centralnej części Górnośląskiego Zagłębia Węglowego. Udziały głównych tlenków (Al2O3, SiO2, Fe2O3, P2O5, K2O, MgO, CaO, Na2O, K2O, MnO, TiO2 i Cr2O3)oznaczono za pomocą XRF. Pierwiastki główne i śladowe (Mo, Cu, Pb, Zn, Ni, Co, U, Cr, V, Mn, As, Th, Sr, Cd, Sb, Bi, Ba, Ti, W, Zr, Ce, Nb, Ta, Be i Sc) analizowano przy pomocy ICP-MS. Głównym celem badań była analiza koncentracji i zmienności stratygraficznej wybranych pierwiastków głównych i śladowych, jak również ocena możliwości stosowania chemostratygrafii w analizie karbońskich i mioceńskich osadów GZW. Badania geochemiczne wykazały odmienne właściwości geochemiczne próbek z karbonu produktywnego oraz miocenu. Zróżnicowanie to wyraża się głównie wzbogaceniem osadów miocenu w Ca i Sr, związane z biogenicznym materiałem węglanowym. Stwierdzono również, że stężenia pierwiastków śladowych, związanych z frakcją detrytyczną, takich jak: Zn, Cr, Co, Ba, Ti, Zr, Nb, Sc, wykazują nieco wyższe wartości w osadach karbonu. Na podstawie koncentracji pierwiastków Ti, Zr i Nb oraz wskaźników geochemicznych Th/U, Zr/Th, Ti/Zr, TiO2/K2O można zidentyfikować jednostki o różnym udziale frakcji terygenicznej, zarówno w osadach karbonu i miocenu. W pracy wykazano, że chemostratygrafia może być z powodzeniem wykorzystywana jako narzędzie stratygraficzne i korelacyjne dla utworów karbonu i miocenu Górnośląskiego Zagłębia Węglowego.

Opis:

Inconsistency in the approach to the corals included by different authors in the families Tachylasmatidae Grabau, 1928 and Pentaphyllidae Schindewolf, 1942 are discussed in the context of their relationship vs homeomorphy to the Family Plerophyllidae Koker, 1924. Following Schindewolf (1942), the pentaphylloid or cryptophylloid early ontogeny, typical of the former two families, is contrasted with the zaphrentoid ontogeny typical of the latter family. Comprehensive analysis proves the independent taxonomic position of the Suborder Tachylasmatina Fedorowski, 1973. The taxa described herein support this idea. The relationship of the two families: Tachylasmatidae and Pentaphyllidae within the framework of this suborder are suggested. A new genus left in open nomenclature (represented by a single specimen) and three new species, Pentaphyllum sp. nov. 1, ? Pentaphyllum sp. nov. 2 and Gen. et sp. nov. 1 are described from lower Bashkirian deposits.

Opis:

Odwierty Z-1/11 i Z-2/12 zlokalizowane są na północ od obszaru górniczego zlikwidowanej kopalni Morcinek – usytuowanej koło Cieszyna, przy granicy Polsko-Czeskiej (rys. 1). Pokłady węgla, w tym rejonie, występują w utworach węglonośnych karbonu w obrębie północno-zachodniej części niecki głównej Górnośląskiego Zagłębia Węglowego. W profilach badanych odwiertów opróbowano ławice węgla występujące w 11 interwałach w otworze Z-1/11 i 14 odcinkach w otworze Z-2/12 (rys. 2). Wykonane badania petrograficzne węgla pozwoliły na oznaczenie stopnia uwęglenia na podstawie pomiarów refleksyjności. Pomierzona refleksyjność średnia (Ror) w otworze Z-1/11 wynosi 0,81%, a w otworze Z-2/12 – 0,84% i wskazuje na zbliżony stopień uwęglenia w obydwu badanych odwiertach, który odpowiada zgodnie z polską normą PN-82/G-97002 węglowi gazowemu o wyróżniku 33. Zgodnie z International Classification of In-Seam Coal na podstawie składu petrograficznego węgiel w obu badanych odwiertach określono jako humusowy. Ze względu na stopień uwęglenia, mierzony wskaźnikiem refleksyjności (Ror) węgiel określono jako medium-rank C (orto-bituminous). Pod względem zawartości popiołu węgiel z poszczególnych pokładów lokuje się w bardzo szerokim zakresie zmienności od high grade coal poprzez medium-low-very low grade coal aż do carbonoceus rock. [...]
The Z-1/11 and Z-2/12 drillings are located north of the closed „Morcinek” coal mine – situated near Cieszyn, close to the Polish-Czech border (Fig. 1). The coal seams in the area are found in Carboniferous coal-bearing formations within the north-western part of the main basin, which is the central part of the Upper Silesian Coal Basin. The profiles of examined drillings included the samples of coal occurring in 11 intervals in the Z-1/11 drilling and 14 sections in the Z-2/12 drilling (Fig. 2). Petrographic studies of coal seams from the Z-1/11 and Z-2/12 drillings allowed to identify the rank of coal on the basis of reflectance measurements. Random reflectance (Ror) of collotelinite in the Z-1/11 drilling is 0.81%, while in the Z-2/12 drilling it is 0.84%. Measured values indicate similar coal rank in both drillings, which corresponds to – according to Polish standard PN-82/G-97002 – gas coal type 33. According to the International Classification of In-Seam Coal, and therefore on the basis of petrographic composition, the coal from both boreholes has been identified as humic coal. On the basis of the rank of coal, measured using the random reflectance (Ror), the coal has been identified as medium-rank C (ortho- bituminous). In terms of ash content, coal from the individual seams has a very high variability, ranging from high grade coal through medium-low-very low grade coal up to carbonoceus rock. [...]

Opis:

W trakcie wieloletnich badań geologicznych karbonu lubelskiego udowodniono występowanie kilku ważnych poziomów litologicznych, które są przydatne do przeprowadzania korelacji profilu karbonu z różnych rejonów Lubelskiego Zagłębia Węglowego. Jednym z nich jest poziom iłowców z Dunbarella usytuowany w dolnej części formacji z Lublina w bezpośrednim stropie pokładu węgla 395(305). Jest to poziom jednorodny litologicznie, ale zmienny pod względem zawartości skamieniałości fauny. Część dolna, o grubości do 0,6 m, zawiera skorupy małżów słodkowodnych z rodzaju Carbonicola i Naiadites. Wyższa część, o grubości około 15 m, oddzielona cienką, 0,35 m warstwą węglanową, zawiera skamieniałości fauny morskiej reprezentowanej przez małże w tym Dunbarella, ramienionogi, głowonogi i ślimaki, a w części stropowej o grubości do około 5,0 m, oprócz fauny Lingula charakterystycznej dla środowisk przejściowych, pojawiają się skamieniałości małżów słodkowodnych Naiadites i Anthracosia. Poziom ten definiuje spąg serii węglonośnej z ekonomicznymi pokładami węgla, a ponadto granicę między westfalem A i B.
Several lithological horizons of correlative importance have been distinguished in the Carboniferous section of the Lublin Coal Basin (Poland). One of them is the marine horizon with Dunbarella, that occurs as a claystone horizon in the lower part of the Lublin Formation, close to the coal seam no. 395 (305). Marine horizon with Dunbarella is lithologicaly unified but unique as it refers to the presence of fauna fossils. In the lower part of this horizon of 0,6m in thickness, shells of freshwater molluscs of Anthracosia and Naiadites occur. In the upper part of 15m in thickness, fossils of marine fauna occur, which are represented by: molluscs (including Dunbarella), brachiopods, cephalopods and gastropods. At the top part of the horizon of 5m in thickness, fossils of Lingula characteristic for brackish water environments occur. The presence of freshwater molluscs of Naiadites and Anthracosia is also indicative of the top part of the horizon. The boundary of marine horizon with Dunbarella between Westphalian A and Westphalian B is acknowledged as the indicative horizon of the bottom part of economic coal-bearing formation of the Carboniferous in the Lublin Coal Basin.
