Opis:
Hydrocarbon generation in the Zechstein Main Dolomite and Upper Triassic potential source rocks of the Polish Basin was investigated by 1-D thermal maturity modelling in 90 boreholes across the basin. This identified major zones potentially worthy of further exploration efforts. The maximum burial depth of the Zechstein Main Dolomite and Upper Triassic reached >5 km during the Late Cretaceous leading to maximum thermal maturity of organic matter. Hydrocarbon generation development reveals considerable differences between particular zones of the Zechstein Main Dolomite and Upper Triassic. The kerogen transformation ratio (TR) in the Zechstein Main Dolomite reached values approaching 100% along the basin axis. The TR in the Upper Triassic source rocks is generally lower than in the Zechstein Main Dolomite due to lesser burial. The Upper Triassic source rocks have the highest TR values (>50%) along the basin axis, in the area between boreholes Piła IG 1 and Piotrków Trybunalski IG 1, with the most pronounced zone in the Krośniewice Trough (i.e., between the Krośniewice IG 1 and Budziszewice IG 1 boreholes), where the TR reached >90%. The Zechstein Main Dolomite and Upper Triassic entered the oil window in the Late Triassic to Early–Middle Jurassic, respectively. Hydrocarbon generation continued until the Late Cretaceous, and was completed during tectonic inversion of the basin.

Opis:
The Cimmerian Continent (or Cimmeria, Cimmerian terrane, Cimmerian blocks) was detached from eastern Gondwana in the Late Paleozoic as a sliver/ribbon of continental strip rifting elements. Recently, these elements belong to an almost continuous long belt (ca. 13,800 km) from central Italy trough Greece, Turkey, Iran, Afghanistan, Tibet, SW China, Myanmar, Thailand up to Indonesia (Sumatra). The palaeogeographic position and relationship of some elements during Permian-Mesozoic times is still matter of discussion. The Qiangtang and Lhasa blocks (present-day Tibet) belong to these elements and their location in space and time and their relationship causes a lot of controversies. Their position alongside eastern Gondwana in the mid-Early Permian (ca. 290–285 Ma) are suggested both by palaeomagnetic and facies studies. Palaeomagnetic studies indicated this position one decade ago, which has been confirmed by recent studies. The Cimmerian Continent [Iran (Alborz)-Qiangtang-Baoshan-Tengchong-Sibumasu] was separated from the Gondwanian part of Pangea during mid-Early Permian time by rifting and drifting. Northwards migration of it took place during Permian-Triassic times caused wide opening of the Bangong‐Nujiang Tethyan Ocean and closing of the Paleotethys Ocean but the Lhasa block was still southern margin of the Bangong‐Nujiang Ocean. The Triassic Indosinian Orogeny has been one of the most spectacular geotectonic event reflecting collision of this continent with Indochina block and closure of the Paleotethys Ocean. The separation of the Lhasa block from Gondwana is enigmatic but most probably took place during earliest Jurassic times. This separation was followed by quick shift northward. Intensive sedimentological studies of the Late Triassic (Carnian-Norian) several flysch-type turbidites in the eastern Tethyan Himalaya (e.g. Qulonggongba, Pane Chaung, Langjiexue, Quehala, Duoburi formations/groups) indicate that their provenance was connected with Lhasa block, which has been their source area during early-stage evolution of the Neotethys. The late Early Permian rift-related basaltic magmatism in northern Baoshan (in SW China) and sourrounding regions was connected with first step of separation from Gondwana margin of this block (together with South Qiangtang and Sibumasu blocks and simultaneously with opening of the Bangong‐Nujiang Ocean before the Middle Permian)  – independently of Lhasa block which was separated later, the most probably during Late Triassic or Triassic/Jurassic transition time with very wide space of the Bangong‐Nujiang Tethyan Ocean between Qiangtang and Lhasa blocks (2,600 km ±710 km  – 23.4° ±6.4° during the Middle Jurassic with its maximum width in the Late Triassic). From the palaeobiogeographic point of view, the worldwide distribution of Pliensbachian-Early Toarcian large bivalves of the so-called Lithiotis-facies, dominated by Lithiotis, Cochlearites, Litioperna genera revealed by the authors’ studies, indicates very rapid expansion of such type of bivalves alongside southern margin of Neotethys, and could be good evidence of palaeogeographic position of the Lhasa block in this time. Himalayan and Tibetan (Nyalam area) occurrences of Lithiotis and/or Cochlearites bivalves could help to place the Lhasa block nearby the Gondwana during Early Jurassic times. This palaeobiogeographic research contradict another interpretation based on different fossils (Permian fusulinids and brachiopods) interpreted as subtropical fauna, which could occur in low subtropical latitudes together with other parts of the Cimmerian Continent.

Opis:
Permian chert and siliceous mudstone in the Soi Dao, Chanthaburi Thailand are extracted the details on radiolarian assemblage and age, change of depositional environment, and geochemical characteristics. Permian radiolarians were obtained in three study areas (ASD01, ASD14 and ASD09); which radiolarian age of each section is as follows: ASD01: Early Asselian to Early Sakmarian, ASD14: Late Sakmarian to Artinskian, and ASD09: Capitanian to Early Changhsingian. Considering the lithofacies, ages, and chemical composition of the rocks, a preliminary stratigraphy consisting of basaltic rock, radiolarian bedded chert, siliceous mudstone, and coarse-grained clastic of alternation of sandstone and mudstone in ascending order can be reconstructed. Data on geochemistry analysis, particularly chondrite-normalized REEs patterns of chert and siliceous mudstone, present a gradual change in that degree of the Ce negative anomaly decrease toward the stratigraphical upper position. These changes indicate that the depositional site of the Permian rocks transferred from a state of high hydrothermal activity to a state of weakened activity and that the influx of terrestrial clastics increased. Permian bedded cherts accompanied by basalts and siliceous mudstones recognized in the study area closely resemble to the Paleo- ‑Tethys bedded cherts in terms of their lithofacies and microscopic features; however, their depositional period is much shorter than that of the Paleo-Tethys, indicating that it was deposited in another oceanic basin. The chemical compositions also show that the influence of hydrothermal activity weakened from the strong state, and the terrigenous clastics rapidly supplied.

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

Opis:
Głównym celem pracy była ocena przydatności wyników interpretacji ilościowej, uzyskanej z obrazowania wewnętrznej struktury próbek skał z wykorzystaniem metody tomografii komputerowej, do szacowania parametrów zbiornikowych takich jak porowatość czy przepuszczalność. W pracy badano zależności korelacyjne pomiędzy parametrami przestrzeni porowej uzyskanymi z analizy obrazów tomografii komputerowej a wynikami standardowych badań laboratoryjnych. Materiał badawczy składał się z próbek piaskowców czerwonego spągowca, facji eolicznej, pobranych z obszaru Niżu Polskiego. Do analiz wybrano kilkadziesiąt próbek skał piaskowców czerwonego spągowca, dla których policzono 69 parametrów. Interpretacja jakościowa i ilościowa polegała na porównaniu parametrów otrzymanych z analizy obrazu tomograficznego z wcześniej uzyskanymi wynikami analiz laboratoryjnych obejmujących następujące metody badawcze: porozymetrię helową (Por.He), spektrometrię jądrowego rezonansu magnetycznego (NMR), porozymetrię rtęciową (Por.Hg) i przepuszczalność absolutną (przepuszcz). Utworzono macierze korelacji dla wszystkich dostępnych parametrów, do pracy wybrano korelacje istotne, o najwyższym współczynniku korelacji liniowej. Zaobserwowano istotne zależności liniowe pomiędzy parametrami wyznaczonymi z analizy obrazów CT i innych metod badawczych. Uzyskano modele pozwalające na szacowanie przepuszczalności, porowatości i zawartości wody nieredukowalnej na podstawie parametrów geometrycznych otrzymanych z obrazów tomograficznych (współczynnik kształtu, charakterystyka Eulera czy powierzchnia właściwa). W efekcie możliwe jest wstępne oszacowanie parametrów petrofizycznych jedynie na bazie wyników z nieniszczącej metody CT. W przypadku obrazowania tomograficznego pełnych rdzeni uzyskane związki pozwalają na wstępną estymację rozkładu porowatości i gęstości objętościowej w całym rdzeniu, co może być pomocne podczas typowania miejsc do poboru próbek rdzeni przeznaczonych do szczegółowych badań laboratoryjnych.
The main purpose of the study was to assess the usefulness of the results of quantitative interpretation of computed tomography (CT) images of rocks’ pore structure for the estimation of reservoir parameters, such as porosity and permeability. This study presents results of correlation analyses between the pore space parameters obtained from the analysis of computed tomography images and the results of standard laboratory tests. The research material consisted of samples representing Rotliegend sandstones of aeolian facies, collected from core material from wells located in the Fore-Sudetic Monocline. Several dozen samples were selected for analysis, for which 69 parameters were calculated. The qualitative and quantitative interpretation consisted in comparing the parameters obtained from the analysis of the tomographic images with the previously obtained results of laboratory analyzes including the following research methods: helium porosimetry (Por.He), nuclear magnetic resonance spectrometry (NMR), mercury porosimetry (Por.Hg) and absolute permeability (let it pass). Correlation matrices for all available parameters were determined, significant correlations with the highest coefficient of linear correlation were selected as a subject of this work. Significant linear relationships were observed between the parameters determined from the analysis of CT images and other research methods. Models that were obtained allowed to estimate the permeability, porosity, and irreducible water content based on geometrical parameters obtained from tomographic images (shape factor, Euler characteristic or specific surface area). The important result of this work is the possibility to estimate petrophysical parameters based on the results of the non-destructive CT method only. In the case of tomographic imaging of whole cores, the obtained results allow for a preliminary estimation of the porosity and volume density distribution in the entire core, which may be helpful in selecting representative samples of core for detailed laboratory tests.

Opis:
This paper describes a sclerobiont association from the Paso Hondo Formation (Roadian, middle Permian), Chiapas, Mexico. Different marine invertebrates such as hederelloids, microconchids, bryozoans, and crinoids (represented by holdfasts) encrusted brachiopod shells belonging to Athyridida and Rhynchonellida. This association is similar to those recorded in different Devonian localities, especially by the co-occurrence of microconchids, hederelloids, and bryozoans. Paleoecological analysis revealed that bryozoans were the most abundant sclerobionts, whereas crinoid holdfasts were uncommon. Likewise, hederelloids and microconchids often settled on hosts previously colonized by bryozoans. Most microconchids encrusted rhynchonellid shells. A positive correlation between the size of the hosts and abundance/diversity of sclerobionts was recorded. The distribution analysis suggests that sclerobiont colonization could have been influenced either by inhalant currents of brachiopods, time of exposure, position of hosts, or by combination of all these factors. Moreover, most of commissures and foramens of brachiopods were not covered by epibionts, suggesting that there was a live interaction. Thus, studied brachiopods were likely encrusted syn vivo, and the interaction between sclerobionts and their brachiopod hosts was likely commensal since there is no damage to the brachiopod valves in the form of malformations or borings. On the contrary, the epibiont cover might have served as a natural shield against predators and parasites. The Roadian age of the association is based on the stratigraphic distribution of host brachiopods. The studied association inhabited open waters on a homoclinal carbonate ramp in the Chicomuselo region. Although encrusted brachiopods belong to the biotic Grandian Province, similar sclerobiont communities have not been previously recorded from the Permian of North America or beyond. The described community represents the youngest record of co-occurring microconchids, hederelloids, and bryozoans, as all previously known similar communities originate from the Late Devonian.

Opis:
To date there is little information on carpal bone homology in late Palaeozoic and Mesozoic Synapsida. Crucial to the understanding of homology in synapsid carpal elements is the fact that different nomenclatures are used for the carpals of non-mammaliamorph Synapsida (Gegenbauer’s canonical nomenclature) and Mammaliaformes (mammalian nomenclature). The homologies of the carpals of non-mammaliamorph synapsids and mammals were established early last century and have not been reviewed since then. Here we provide a detailed study of the carpal bones of synapsids ranging in age from the early Permian to Late Cretaceous. The mammaliamorph lunate, previously considered the homologue of the intermedium of non-mammaliamorph synapsids, is interpreted here as homologous to their lateral centrale. We interpret the single mammaliamorph centrale as a homologue of the medial centrale of non-mammaliamorph synapsids. In some synapsid specimens, we found that one or two centralia are fused to the radiale (e.g., the gorgonopsian Arctognathus and tritylodontid Bienotheroides), supporting a digging habit. A third centrale is present in the therocephalian Theriognathus, very likely an abnormal duplication. An additional medial bone in a biarmosuchian was interpreted as a prepollex/ sesamoid. A cartilaginous prepollex/sesamoid may also have been present in several non-mammaliamorph synapsids, which have an open space proximal to distal carpal I. Distal carpal V is completely lost in dicynodonts and it is mainly fused to distal carpal IV in the adult stage of most other therapsid groups, but showed a delayed development in most non-mammaliamorph cynodonts. In mammaliamorphs, distal carpal V is not present. Our observations provide an updated revision of synapsid carpal homologies, mainly on the basis of position and anatomical contacts and also taking into account the results of embryological studies.

Opis:
A unique functional adaptation to herbivory within early ray-finned fishes is exemplified by the late Permian actinopterygians within the family Eurynotoidiidae with policuspid teeth strongly modified with respect to the primitive actinopterygian conditions. Here we report additional finds of multidenticulated teeth from the fluvial latest Permian deposits of Russia. The teeth belong to the members of endemic Eurynotoidiidae and show rather high morphological diversity. We confirm that the Russian forms are the earliest known ray-finned fishes with substantial modifications of teeth adapted to the processing of food. These finds confirm some previous suggestions that the adaptation to herbivory first developed in freshwater fishes, not marine. We found very similar dental adaptations in some groups of Recent freshwater teleosts, especially in characiforms and cichlids. It suggests that sympatric species of Permian Eurynotoidiidae explored various herbivorous niches like modern fish in East African lakes. Apparently, this first pulse of adaptive radiation in ray-finned fishes was probably caused by diversification of Permian aquatic vertebrate community.

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.

Wysad solny Lubień jest jedną z kilkudziesięciu struktur solnych występujących na Niżu Polskim. Został zidentyfikowany badaniami grawimetrycznymi, prowadzonymi w latach 1937-1950. Zalega w formie nieregularnego słupa solnego, zwężającego się wraz z głębokością. W przekroju poprzecznym wysad ma kształt kolisty o maksymalnej średnicy około 2,8 km. Wnętrze wysadu budują ewaporaty cechsztyńskiej serii solnej, które są przykryte czapą anhydrytowo-gipsowo- -ilastą. W otoczeniu wysadu występują utwory jury górnej i środkowej, nad którymi zalegają osady paleogenu i neogenu oraz czwartorzędu. W rejonie występowania wysadu odwiercono 31 otworów, z których 20 nawierciło serię solną. Zostały też wykonane liczne badania i pomiary geofizyczne. Na podstawie danych z pomiarów sejsmicznych wykonanych w 2014 roku oraz ich reprocesingu i reinterpretacji w 2017 i 2018 roku, opracowano modele przestrzenne wysadu Lubień i zaktualizowano podstawowe parametry wysadu.
The Lubień Salt Dome is one of the several dozen salt structures found in the Polish Lowlands. He was identified by gravimetric research conducted in the years 1937-1950. It lies in the form of an irregular salt column, narrowing with depth. In its cross-section, the dome has a circular shape with a maximum diameter of about 2.8 km. The interior of the dome is built by evaporates of the Zechstein salt series, which are cooverlain by an anhydrite-gypsum-clay cap-rock. In the vicinity of the dome there are Upper and Middle Jurassic formations over which Palaeogene, Neogene and Quaternary deposits. 31 holes were drilled in the area of the dome, 20 of which drilled a series of salt. Numerous geophysical surveys and measurements were also made. Based on the data from seismic measurements made in 2014 and their reprocessing and reinterpretation in 2017 and 2018, spatial models of the Lubień Salt Dome were developed and the basic parameters of the dome were updated.

Opis:
Based on the reinterpretation of gravimetric, magnetic, seismic and magnetotelluric studies, new features of the sub-Permian basement in the area between the Dolsk Fault and the Middle Odra Fault, SW Poland, are identified. Among numerous faults and lineaments indicated in the article, those limiting both the Wolsztyn–Pogorzela High and a positive anomaly in the Lower Silesian Basin, as well as the faults in the vicinity of the Odra River are particularly prominent. N-S oriented structural elements are also visible in the gravity image. One of them separates the Pogorzela High from the Wolsztyn High. In light of the obtained results, according to refraction seismic surveys, the Polish equivalent to the Mid-German Crystalline Rise is located farther north from commonly accepted position within the Middle Odra Metamorphic Complex. The study results, supported by data from the neighboring area of Germany, may be important for further prospecting for sediment-hosted Cu and other metal deposits. The reprocessing of archival geophysical data using method of effective reflection coefficients (ERC) enabled the creation of more accurate structural model of ore series within the area of the Nowa Sól deposit in SW Poland. In terms of mineral resource prospects, this creates the possibility of applying new results from the study area to the similar zones in the corresponding part of Germany, which is the area between the phyllite zone and the Harz Mountains hosting very diverse and rich mineralization.

Zaprezentowano wyniki badań i reinterpretację materiałów geofizycznych (grawimetrycznych, magnetycznych, sejsmicznych i magnetotellurycznych) dla ustalenia związków korelacyjnych, w tym pomiędzy tektoniką obserwowaną na przekrojach sejsmiki płytkiej i głębokiej. Interpretacja przetworzonych danych grawimetrycznych pozwoliła na wyznaczenie charakterystycznych struktur oraz regionalnych stref zaangażowania tektonicznego. Wstępny model geofizyczno-geologiczny wzdłuż linii Wschowa–Brenno–Śrem (SW-NE) obrazuje efekty kompleksowej interpretacji wyników badań geofizycznych i otworowych. Rezultaty pokazują, że odpowiedni dobór i sposób zastosowanych metod stwarza szanse na uzyskanie realnych wyników w zakresie rozpoznania budowy geologicznej podłoża podpermskiego rejonu, z możliwością nawiązania do sąsiedniego obszaru Niemiec. Wyniki badań stanowią wkład do dyskusji dotyczącej hipotezy kontynuacji podłoża krystalicznego platformy wschodnioeuropejskiej pod paleozoiczną platformę zachodnioeuropejską, sięgającego ku SW aż po strefę uskokową środkowej Odry. Artykuł prezentuje również przykład kompleksowego wykorzystania metod geofizycznych (grawimetrycznych, magnetycznych i sejsmicznych) w prospekcji głębokich złóż rud miedzi na obszarze monokliny przedsudeckiej w SW Polsce.

Opis:
Determining the thermal maturity of palynomorph based on their color is a method commonly used in hydrocarbon prospecting. The color of the outer membrane of miospores (exine) changes as a result of heating from pale yellow to black depending on the paleotemperature. Currently, there are many palynomorph color scales correlated with the value of vitrinite reflectance, temperature of burial and hydrocarbon generation stages. Due to the varied material, both in taxonomic and morphological terms, the author used the TAI AMOCO scale. Furthermore, the share of individual kerogen groups in palynofacies was analyzed in terms of their hydrocarbon potential. The Upper Permian and Triassic deposits from eleven boreholes located in the north part of the Nida Basin were investigated. They showed that the Triassic and in the Upper Permian samples from the Milianów IG 1 borehole, are dominated by the pale yellow to orange color of spores and pollen grains, corresponding to a TAI index from 1 to 4, i.e. the pre-generation, dry gas and the early oil generation windows. In turn, only the samples of the Upper Permian from the Pągów IG 1 borehole are dominated by the brown color of miospores, which corresponds to a TAI index from 4+ to 5, i.e. the peak oil prone. Dominant vitrinite reflectance Ro varies from 0,4% to 0,6%, so the degree of organic matter maturity in the Upper Permian and Triassic deposits is not very high, which indicates relatively low temperatures of sediment diagenesis (< 80°C). Analysis of palynofacies showed that the Upper Permian and Triassic deposits contain mixed and structural kerogen. Mixed kerogen, occurring in carbonate rocks, contains amorphous fine-scattered kerogen and “fluffy” of algae origin, as well as structural kerogen of terrigeneous origin, mainly exinite and vitrinite. Mixed kerogen is characterized by oil potential, whereas structural kerogen – by gas-oil potential.

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

Opis:
Campyloprion Eastman, 1902 is a chondrichthyan having an arched symphyseal tooth whorl similar to that of Helicoprion Karpinsky, 1899, but less tightly coiled. The holotype of Campyloprion annectans Eastman, 1902, the type species of Campyloprion, is of unknown provenance, but is presumed to be from the Pennsylvanian of North America. Campyloprion ivanovi (Karpinsky, 1922) has been described from the Gzhelian of Russia. A partial symphyseal tooth whorl, designated as Campyloprion cf. C. ivanovi, is reported from the Missourian Tinajas Member of the Atrasado Formation of Socorro County, New Mexico, USA. Partial tooth whorls from the Virgilian Finis Shale and Jacksboro Limestone Members of the Graham Formation of northern Texas, USA, are designated as Campyloprion sp. Two partial tooth whorls from the Gzhelian of Russia that were previously referred to C. ivanovi are designated as Campyloprion cf. C. annectans. The age of Toxoprion lecontei (Dean, 1898), from Nevada, USA, is corrected from the Carboniferous to the early Permian. An alternative interpretation of the holotype of T. lecontei is presented, resulting in a reversal of its anterior-to-posterior orientation. The genera Helicoprion, Campyloprion, and Shaktauites Tchuvashov, 2001 can be distinguished by their different spiral angles.

Opis:
The distribution of Permian alluvial fan lithofacies in a quarry at Zygmuntówka near Chęciny, Holy Cross Mts., in southern Poland was investigated using ground penetrating radar (GPR) in order to create a training image for multiple point statistics (MPS) reconstructions of alluvial fan sedimentary facies. Five pseudo-3D GPR datasets were collected, processed and uploaded for interpretation into SKUA-GOCAD 3D geological modelling software. Three radar facies were distinguished based on the 3D geometrical pattern of radar reflections and linked to lithofacies described from the quarry by Zbroja et al. (1998). A statistical summary showed that ~50% of the lithofacies resulted from gravity flows (mostly non-cohesive), while the remaining proportion was deposited by unconfined and confined flash floods. Fluvial sedimentary facies left by waning of catastrophic floods or reworking during fair weather, alihough not prevalent, could not be distinguished from confined flood deposits based only on GPR data. The GPR datasets together with information from field observations were used to carry out MPS simulations and estimate the most probable 3D model of lithofacies at the quarry scale. This model will in turn serve as a training image for MPS reconstructions of alluvial-fan facies of Rotliegend conglomerates in the multi-scale geological model of the Gorzów Block (western Poland).
