This event was synchronous with volcanism of the Central Atlantic Magmatic Province (CAMP), the ultimate cause of the extinction and related environmental perturbations. However, the continental weathering response to CAMP‐induced warming remains poorly constrained. Strontium isotope stratigraphy is a powerful correlation tool that can also provide insights into the changes in weathering regime, but the scarcity of 87 Sr/ 86 Sr data across the Triassic‐Jurassic boundary (TJB) hindered the use of this method. Here we present new high‐resolution 87 Sr/ 86 Sr data from bulk carbonates at Csővár, a continuous marine section that spans 2.5 Myrs across the TJB. We document a continuing decrease in 87 Sr/ 86 Sr ratio from the late Rhaetian to the ETE, terminated by a 300 kyr interval of a flat trend and followed by a transient increase in the early Hettangian that levels off. We suggest that the first in the series of perturbations is linked to the influx of non‐radiogenic Sr from the weathering of freshly erupted CAMP basalts, leading to a delay in the radiogenic continental weathering response. The subsequent rise in 87 Sr/ 86 Sr after the TJB is explained by intensified continental crustal weathering from elevated CO 2 levels and reduced mantle‐derived Sr flux. Using Sr flux modeling, we also find support for such multiphase, prolonged continental weathering scenarios. Aggregating the new data set with published records employing an astrochronological age model results in a highly resolved Sr isotope reference curve for an 8.5 Myr interval around the TJB.}, year = {2024}, eissn = {1525-2027}, orcid-numbers = {Katchinoff, Joachim/0000-0003-1286-8344; Planavsky, Noah/0000-0001-5849-8508; Pálfy, József/0000-0001-9686-1849} } @inproceedings{MTMT:34741129, title = {Az állampolgári ismeretek tantárgy kapcsolata a földrajz és a történelem tantárggyal a társadalmi és a gazdasági folyamatok tanulása során}, url = {https://m2.mtmt.hu/api/publication/34741129}, author = {Seres , Zoltán}, booktitle = {I.

All coprolites mainly consist of apatite, indicating most probably a carnivorous diet. No evidence of herbivory has been found so far. The coprolites contain remains belonging to several groups: ostracod carapaces, bivalve shells, vertebrae from bony fishes, fish scales, as well as teeth. The CT scans show inhomogeneities in the matrix; however, in most cases they do not reliably indicate inclusions. The taphonomical features suggest rapid burial and most likely an aquatic origin.

During their evolution, they underwent gradual craniodental changes from the Early Anisian to the Rhaetian, such as a reduction in the number of teeth, an increase in the size of the posterior palatal teeth, an elongation of the premaxilla/rostrum, and a widening of the temporal region. These changes are presumably related to changes in dietary habits, which, we hypothesise, are due to changes in the type and quality of food they consumed. In the present study, the dental wear pattern of a total of nine European Middle to Late Triassic placodont species were investigated using 2D and 3D microwear analyses to demonstrate whether there could have been a dietary shift or grouping among the different species and, whether the possible changes could be correlated with environmental changes affecting their habitats. The 3D analysis shows overlap between species with high variance between values and there is no distinct separation. The 2D analysis has distinguished two main groups. The first is characterised by low number of wear features and high percentage of large pits. The other group have a high feature number, but low percentage of small pits. The 2D analysis showed a correlation between the wear data and the size of the enlarged posterior crushing teeth. Teeth with larger sizes showed less wear feature (with higher pit ratio) but larger individual features. In contrast, the dental wear facet of smaller crushing teeth shows more but smaller wear features (with higher scratch number). This observation may be related to the size of the food consumed, i.e., the wider the crown, the larger food it could crush, producing larger features. Comparison with marine mammals suggests that the dietary preference of Placochelys , Psephoderma and Paraplacodus was not exclusively hard, thick-shelled food. They may have had a more mixed diet, similar to that of modern sea otters. The diet of Henodus may have included plant food, similar to the modern herbivore marine mammals and lizards.}, year = {2024}, eissn = {1664-2384}, orcid-numbers = {Ősi, Attila/0000-0003-2967-997X} } @article{MTMT:34568108, title = {Review on vegetation, landscape and climate changes in the Carpathian Basin during the Neolithic and Chalcolithic period}, url = {https://m2.mtmt.hu/api/publication/34568108}, author = {Magyari, Enikő Katalin and Raczky, P and Merkl, Máté and Pálfi, Ivett and Darabos, Gabriella and Hajnalova, M and Moskal-Hoyo, M}, doi = {10.1007/s00334-024-00986-w}, journal-iso = {VEG HIST ARCHAEOBOT}, journal = {VEGETATION HISTORY AND ARCHAEOBOTANY}, unique-id = {34568108}, issn = {0939-6314}, abstract = {The Neolithic and Copper Age (CA) of Hungary (6000–2800 cal bc ) represents a meticulous construction of settlement structure, material culture, arable farming and herding techniques with at least one, but likely several reappearing population movements that brought in innovations and possibly contributed to the societal changes in this period. The last couple of decades witnessed a considerable progress in the study of concurrent vegetation, climate and landscape management changes particularly via the increased number of high-resolution pollen records, archaeobotanical and archaeological investigations, coupled with stable isotope analyses of the charred cereal assemblages. In this review we synthetize the results of these research projects and demonstrate that the Neolithic and CA landscapes of Hungary were characterised by mixed oak forest communities, and in the territory of Hungary thermophilous steppe oak forests were present in the lowland landscape that were the principal choice of early farmers represented by the Körös-Starčevo-Criş cultures. Climate modelling and climate reconstruction from these regions indicate higher than preindustrial summer mean temperatures and higher than modern summer rainfall. We demonstrate that Linear Pottery Culture was the first culture that technologically advanced to clear larger plots of land for crop cultivation purposes.

By comparing our data to other fluids and melts from various carbonatite systems, we constructed a model for fluid-mediated rare earth element transport and mineralization. We show that carbonatite-related fluids are rich in alkali-carbonate + sulfate + chloride and CO2, but poor in H2O, and they can be significant carriers of rare earth elements (>1600 ppm). We argue that fluid CO2 contents are essential to preclude or slow down the interaction with wall rock during migration and that fluid-mediated rare earth element mineralization occurs when partial pressure of CO2 decreases in the fluid (i.e., during degassing).}, year = {2024}, eissn = {1943-2682}, pages = {x}, orcid-numbers = {Berkesi, Márta/0000-0003-4380-057X; Guzmics, Tibor/0000-0002-9060-3774} } @article{MTMT:34504775, title = {A borostyán: a tantárgyakat összekötő gyanta}, url = {https://m2.mtmt.hu/api/publication/34504775}, author = {Somogyi, Éva}, journal-iso = {GEOMETODIKA}, journal = {GEOMETODIKA: FÖLDRAJZ SZAKMÓDSZERTANI FOLYÓIRAT}, volume = {8.}, unique-id = {34504775}, year = {2024}, eissn = {2560-0745}, pages = {27-48}, orcid-numbers = {Somogyi, Éva/0009-0005-1212-2034} } @article{MTMT:34472636, title = {Incorporating high-resolution climate, remote sensing and topographic data to map annual forest growth in central and eastern Europe}, url = {https://m2.mtmt.hu/api/publication/34472636}, author = {Jevšenak, J and Klisz, M and Mašek, J and Čada, V and Janda, P and Svoboda, M and Vostarek, O and Treml, V and van der Maaten, E and Popa, A and Popa, I and van der Maaten-Theunissen, M and Zlatanov, T and Scharnweber, T and Ahlgrimm, S and Stolz, J and Sochová, I and Roibu, CC and Pretzsch, H and Schmied, G and Uhl, E and Kaczka, R and Wrzesiński, P and Šenfeldr, M and Jakubowski, M and Tumajer, J and Wilmking, M and Obojes, N and Rybníček, M and Lévesque, M and Potapov, A and Basu, S and Stojanović, M and Stjepanović, S and Vitas, A and Arnič, D and Metslaid, S and Neycken, A and Prislan, P and Hartl, C and Ziche, D and Horáček, P and Krejza, J and Mikhailov, S and Světlík, J and Kalisty, A and Kolář, T and Lavnyy, V and Hordo, M and Oberhuber, W and Levanič, T and Mészáros, Ilona and Schneider, L and Lehejček, J and Shetti, R and Bošeľa, M and Copini, P and Koprowski, M and Sass-Klaassen, U and Izmir, ŞC and Bakys, R and Entner, H and Esper, J and Janecka, K and del Castillo, EM and Verbylaite, R and Árvai, Mátyás and de Sauvage, JC and Čufar, K and Finner, M and Hilmers, T and Kern, Zoltán and Novak, K and Ponjarac, R and Puchałka, R and Schuldt, B and Dolar, NŠ and Tanovski, V and Zang, C and Žmegač, A and Kuithan, C and Metslaid, M and Thurm, E and Hafner, P and Krajnc, L and Bernabei, M and Bojić, S and Brus, R and Burger, A and D'Andrea, E and Đorem, T and Gławęda, M and Gričar, J and Gutalj, M and Horváth, E and Kostić, S and Matović, B and Merela, M and Miletić, B and Morgós, A and Paluch, R and Pilch, K and Rezaie, N and Rieder, J and Schwab, N and Sewerniak, P and Stojanović, D and Ullmann, T and Waszak, N and Zin, E and Skudnik, M and Oštir, K and Rammig, A and Buras, A}, doi = {10.1016/j.scitotenv.2023.169692}, journal-iso = {SCI TOTAL ENVIRON}, journal = {SCIENCE OF THE TOTAL ENVIRONMENT}, volume = {913}, unique-id = {34472636}, issn = {0048-9697}, year = {2024}, eissn = {1879-1026}, orcid-numbers = {Kern, Zoltán/0000-0003-4900-2587} } @article{MTMT:34412174, title = {Lithostratigraphy of the ignimbrite-dominated Miocene Bükk Foreland Volcanic Area (Central Europe)}, url = {https://m2.mtmt.hu/api/publication/34412174}, author = {Hencz, Mátyás and Biró, Tamás and Németh, Károly and Szakács, Alexandru and Portnyagin, Maxim and Cseri, Zoltán and Pécskay, Zoltán and Szabó, Csaba and Müller, Samuel and Karátson, Dávid}, doi = {10.1016/j.jvolgeores.2023.107960}, journal-iso = {J VOLCANOL GEOTH RES}, journal = {JOURNAL OF VOLCANOLOGY AND GEOTHERMAL RESEARCH}, volume = {445}, unique-id = {34412174}, issn = {0377-0273}, abstract = {This study documents the volcanic evolution of the Miocene silicic Bükk Foreland Volcanic Area (BFVA), Northern Hungary (Central Europe) at an event-scale. The BFVA is a deeply eroded and dissected volcanic field dominated by multiple, several 10-m thick, valley-filling silicic ignimbrite units, which are chemically and texturally very similar to each other. Hence, establishing lateral correlation is a real challenge due to the sporadic and small-scale outcrops and lack of stratotypes. Detailed field observations allowed us to identify eleven lithological members including fourteen eruption events and establish a nearly complete lithostratigraphic correlation between fifteen outcrops across the BFVA. Primary pyroclastic material of each member was sampled, and volcanic glass was analyzed for major and trace element composition. The geochemical results confirm the field-based classification of the members and enable the correlation of distinct outcrops. The major and trace element composition of the glassy pyroclasts of each member of the BFVA served as basis to create a field-wide chemical reference database for regional correlational studies. Here, a new lithostratigraphic classification scheme consisting of one formation and eleven members is presented, which reflects the challenges unraveling the stratigraphy of ancient volcanic terrains. The field-based event-scale lithostratigraphy of the BFVA suggests a wet, partly sea-covered depositional environment in the close vicinity of the eruption centers providing favorable conditions to ‘fuel’ silicic explosive phreatomagmatism. On the contrary, paleosol horizons formed after almost each major eruption event or sequence suggests an overall near-coast terrestrial environment for the BFVA, where the emplacement of the pyroclastic material occurred.}, keywords = {STRATIGRAPHY; phreatomagmatism; ignimbrite; Correlation; lithostratigraphy; Glass geochemistry; Volcanic geology; Reworked pyroclasts}, year = {2024}, eissn = {1872-6097}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Szabó, Csaba/0000-0002-1580-6344; Karátson, Dávid/0000-0003-0386-1239} }
