This paper examines the origin and geological structure of the Lublin Coal Basin, focusing on the development of the Lubelski Węgiel "Bogdanka" S.A. mine. The study outlines the history of exploration initiated in the interwar period, which ultimately resulted in the documentation of hard coal deposits in the Lublin region. The lithostratigraphy and tectonic evolution of the sedimentary basin are analyzed, with emphasis on the Lublin Beds that host multiple seams of thermal coal characterized by favorable quality parameters. The Carboniferous flora and fauna are discussed in relation to their role in coal-forming sedimentary environments. Methodological considerations address techniques of deposit recognition and documentation, including geological mapping, core drilling, and lithological studies. Digital deposit modeling is presented as a key tool for mine planning and operational optimization. The study highlights its importance for data standardization, decision-making integration, and sustainable resource management.

The article is a report from my stay in Scotland, at the IAS Conference 2024, together with a fieldtrip, entitled: Carboniferous Sediments of the Kingdom of Fife. A hike along the Scottish coast, surrounded by beautiful and mysterious cliffs, documented with numerous photos turned out to be very inspiring. The wealth of impressions, sensations and observations was caused not only by contact with geology, but also by the beauty of Scottish landscapes, cultural richness and found traces of Polish history. Participating in it allowed us to spend two wonderful days experiencing the diversity and colours of the Carboniferous rocks, beautifully exposed on Scottish beaches exposed to low tide. The article contains selected information about the geography, geology and history of the east coast of Scotland, sprinkled with a handful of memories, and is an encouragement to take the tourist risk of facing the weather... and see with your own eyes the beauty, mystery and danger of the Scottish cliffs.

Post-orogenic, post-collisional, intracontinental Permian-Carboniferous volcanism in the Sudetes, Central Europe, marked the transition from the Variscan Orogeny to the continental rifting in the eastern central Pangea. The volcanic rocks are part of volcano-sedimentary successions found in the Intra-Sudetic and North-Sudetic synclinoria. Between 313-287 Ma and culminating around 299 Ma, magmas originated from subduction-modified mantle sources and evolved in crustal magma chambers yielding rhyolitic ignimbrites and lavas with less widespread rocks of andesitic and trachyandesitic compositions. The older volcanic rocks reveal supra-subduction geochemical characteristics, while the younger ones show more pronounced within-plate signatures. Several tens of volcanic centres formed in the region, including lava fields, shield volcanoes, large rhyolite extrusions, ignimbrite caldera, maars and tuff rings, and numerous laccoliths and sills. Volcanic edifices underwent substantial erosion and supplied volcanogenic detritus into local depositional systems, while the caldera acted as an intrabasinal depositional centre. The volcanic rocks are significantly affected by post-volcanic and, mostly, diagenetic alteration. In recent years the extinct Permian-Carboniferous volcanoes became more widely recognized as regional nature attraction and part of the UNESCO Global Geoparks network.

The paper presents geological implications of new results of biostratigraphic studies (mainly palynostratigraphic) of Carboniferous rocks from the central part of the Sudetes. They brought important changes in stratigraphy, most often showing younger age of studied rocks than it was believed earlier. The onset of sedimentation in the Intra-Sudetic Basin, initially in the continental environment, was not earlier than in the middle Visean. Marine sediments, previously considered to be a manifesta¬tion of the Late Viseanian transgression, were found to be diachronic (from the late Visean to the Namurian C). Among profiles of the Szczawno Formation and its lithologic equivalents that were previously considered to be Upper Visean, only two profiles: Ptasia Góra in the Intra-Sudetic Basin and Paprotnia in the Bardo Unit, represent the uppermost Visean. Most of the other profiles from the Wałbrzych region turned out to represent the Namurian A (Serpukhovian) or even Namurian B and C (Bashkirian age) in the case of some profiles in the Sowie Mountains Massif. The late Visean-early Namurian (Serpukhovian) age range also encompasses marine mudstones from the southern part of the Świebodzice Unit, which were previously considered Late Devonian. This discovery is of great importance for the model of development of the Świebodzice Unit. Consequently, the timing of the marine sedimentation in different geological units of the middle part of the Sudetes should be revised. The coal bearing rocks of the Wałbrzych Formation, analysed in the study, are of Namurian A (upper Serpukhovian and lower Bashkirian) age. The Biały Kamień Formation was included in the Namurian B and C and Westphalian A (Bashkirian), the Żacler Formation - in the Westphalian A-C (Bashkirian and Moscovian), and the Glinik Formation - in the Westphalian D(?). The documentation of successive miospore zones from VF to OT(?) indicates that there are no stratigraphic gaps in the Upper Visean-Westphalian D (?) interval in the Intra-Sudetic Basin. The problem of the chronostratigraphic significance of miospores dating the Walchia shales in the Intra-Sudetic Basin and the need to reinterpret the location of the Carboniferous/Permian boundary are also discussed.

The aim of the research was a detailed sedimentological and petrographic analysis of the Dziwna Formation (Stephanian-?Autunian) in the Strzeżewo 1 borehole section in Western Pomerania. The results provided the new data on lithology, depositional environments and petrographic-mineralogical composition. They showed that sedimentation occurred in the environment of braided and anastomosing rivers in incised valleys. The composition of the sandstones indicates that they are more similar to the Carboniferous than to the Lower Permian (Rotliegend) sediments. This provides a basis for attempting to determine the boundary between the systems.

A small phyllocarid faunule comprising Dithyrocaris colei Portlock, 1843, D. cf. granulata Woodward & Etheridge, 1873 and Phyllocarida indet. is described from black shale beds within coal-bearing deposits of the Mospyne Formation (upper Bashkirian, Lower Pennsylvanian) in the central Donets Basin, eastern Ukraine. All records of Carboniferous phyllocarids from the Donets Basin, including those by previous researchers, are preserved in black shales formed under dysaerobic conditions. In the Carboniferous of the Donets Basin, phyllocarids are found predominantly in the Bashkirian interval. Significantly fewer taxa have been recorded from the Serpukhovian, the Serpukhovian/Bashkirian boundary interval and the Upper Pennsylvanian.

On the basis of palynologic and palynofacies data from the Biały Kamień Formation in the Intra-Sudetic Basin (ISB), the composition of parent plant communities and the depositional environment during sedimentation of this unit were reconstructed. The results were then compared with earlier published palynological data from the stratigraphically older and younger lithostratigraphical units, the Wałbrzych and Žacléř formations, allowing a general interpretation of floristic and environmental changes throughout the Serpukhovian to Moscovian interval. The floras in the Serpukhovian resemble the composition in the Moscovian. In both, their main feature is low lycopsid abundance, indicating relatively dry palaeoclimatic conditions. In contrast, the Bashkirian records a gradual increase in lycopsids and sphenopsids, peaking in the late Bashkirian during the maximum humid phase. This was followed in the Moscovian by a marked decline in lycopsids and a shift toward fern dominance, reflecting a transition to a drier climate associated with the First Dry Interval, proposed by Phillips and Peppers (1984). At the same time, the miospore record shows no evidence of abrupt floristic changes, contradicting the concept of a “floristic leap” at the Namurian A/B boundary.

The purpose of the study was petrographic-mineralogical analysis of volcaniclastic rocks occurring in the Lublin Basin, within the K³odnica Member (Tournaisian, Visean), in seven boreholes. Its results were linked with the results of sedimentological and sequence stratigraphy studies to reconstruct the genesis of the sediments, as well as spatial and age relationships. Fine and coarse ash tuffs were identified, whose composition indicates acidic and alkaline volcanism. Accompanying volcaniclastic conglomerates and sandstones were formed mainly in the Tournaisian, before volcanic activity began. These sediments fill incised valleys, and belong to the oldest Carboniferous sedimentary filling of the Lublin Basin.

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.

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.

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.

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.

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.

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.

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.

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

The Family Kumpanophyllidae Fomichev, 1953, synonymised by Hill (1981) with the Family Aulophyllidae Dybowski, 1873, is emended and accepted as valid. The new concept of this family, based on both new collections and discussion on literature data, confirms the solitary growth form of its type genus Kumpanophyllum Fomichev, 1953. However, several fasciculate colonial taxa, so far assigned to various families, may belong to this family as well. The emended genus Kumpanophyllum forms a widely distributed taxon, present in Eastern and Western Europe and in Asia. Its Serpukhovian and Bashkirian occurrences in China vs Bashkirian occurrences in the Donets Basin and in Spain, may suggest its far-Asiatic origin, but none of the existing taxa can be suggested as ancestral for that genus. Thus, the suborder position of the Kumpanophyllidae remains unknown. Four new species: K. columellatum, K. decessum, K. levis, and K. praecox, three Kumpanophyllum species left in open nomenclature and one offsetting specimen, questionably assigned to the genus, are described.

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.

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.
