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} } @misc{MTMT:34547257, title = {Tectonically Determined Distribution of Intracontinental Basaltic Volcanoes in a Compressive Tectonic Regime: A GIS Approach}, url = {https://m2.mtmt.hu/api/publication/34547257}, author = {Hencz, Mátyás and Biró, Tamás and Németh, Károly and Porkoláb, Kristóf and Kovács, István János and Spránitz, Tamás and Sierd, Cloetingh and Szabó, Csaba and Berkesi, Márta}, unique-id = {34547257}, abstract = {By analysing of spatial aspects of a monogenetic volcanic field, knowledge can be acquired on the relationships between the basaltic magmatism and regional tectonics, like impact of faults to the position of the volcanoes, vent propagation in the lithosphere, age-dependent stress condition changes. Examination of the surface patterns of volcanoes might help us understand better the process of magma generation, segregation, and how magma travelled through a thin lithosphere. Moreover, by studying these processes, we can get closer to understanding the evolution of a sedimentary basin in which we can find the link between volcanism and a changing but essentially compressive stress field, where basaltic volcanism is not evident. These spatial patterns of volcanoes can be examined using GIS (geographic information systems). The study area was the Mio-Pleistocene, monogenetic Bakony-Balaton Highland Volcanic Field (BBHVF, Carpathian-Pannonian region, Central Europe), which is located in continental back-arc setting and compressive/transpressive tectonic regime. The methodological toolkit included creating heatmap based on the spatial distribution of the volcanoes, measuring the orientation of the volcanic field comparing the orientation of the faults in the region, and calculating distance to the nearest fault line from each volcanic centre. Poisson nearest neighbour analysis was used to evaluate how clustered or random the occurrence of the volcanoes across the volcanic field. All volcanic lineaments (whether volcanic centres are situated along lines) were calculated, and their orientation was measured to see any systematic directions. The results suggest that the locations of the volcanoes in the BBHVF are most probably tectonically determined. The orientation of volcanic lineaments is also the same as the bounding geometries and the faults. Density of the volcanic centre distribution is the largest in the central area of the BBHVF along a major inactive thrust fault. We speculate that the NW dipping fault plane of this fault could be a ‘catchment area’ in the upper crust (just above the brittle-ductile transition zone), which channelized the magmas and helped them reach the surface. Volcanoes in larger distance from any faults have typically larger volume, and longer active period (several 100 ky), thus their magmas needed to have larger buoyancy to reach the surface without the help of any fault planes. Age pattern and spatial density suggest volcanism getting younger and thicker towards the central part of the BBHVF. Thus, intracontinental monogenetic volcanism in compressional regime is strongly influenced by lithospheric weaknesses and the regional stress field.}, year = {2023}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Porkoláb, Kristóf/0000-0001-7470-8296; Kovács, István János/0000-0002-3488-3716; Spránitz, Tamás/0000-0002-5086-3133; Szabó, Csaba/0000-0002-1580-6344; Berkesi, Márta/0000-0003-4380-057X} } @CONFERENCE{MTMT:34523585, title = {Fluid and melt inclusions trapped at different geodynamic settings – how can small droplets contribute to the tectonic models?}, url = {https://m2.mtmt.hu/api/publication/34523585}, author = {Berkesi, Márta and Spránitz, Tamás and Guzmics, Tibor and Aradi, László Előd and Hencz, Mátyás and Szabó, Cs. and Kovács, I.J. and Myovela, J.L.}, booktitle = {19th meeting of the Central European Tectonic Studies Group (CETeG)}, unique-id = {34523585}, year = {2023}, pages = {1}, orcid-numbers = {Berkesi, Márta/0000-0003-4380-057X; Spránitz, Tamás/0000-0002-5086-3133; Guzmics, Tibor/0000-0002-9060-3774; Aradi, László Előd/0000-0003-0276-3119; Hencz, Mátyás/0000-0001-9716-5714} } @CONFERENCE{MTMT:34441838, title = {FluidsByDepth: an inclusion-based research project on the better understanding of lithosphere-scale fluid transfer}, url = {https://m2.mtmt.hu/api/publication/34441838}, author = {Berkesi, Márta and Szabó, Csaba and Spránitz, Tamás and Hencz, Mátyás and Németh, Károly and Török, Kálmán and Békési, Eszter and Porkoláb, Kristóf and Palcsu, László and Kővágó, Ákos}, booktitle = {Goldschmidt 2023 Conference: abstracts}, doi = {10.7185/gold2023.20552}, unique-id = {34441838}, year = {2023}, orcid-numbers = {Berkesi, Márta/0000-0003-4380-057X; Szabó, Csaba/0000-0002-1580-6344; Spránitz, Tamás/0000-0002-5086-3133; Hencz, Mátyás/0000-0001-9716-5714; Békési, Eszter/0000-0003-3561-1656} } @article{MTMT:34402078, title = {A földrengések szerepe a CO2-gazdag fluidumok szállításában}, url = {https://m2.mtmt.hu/api/publication/34402078}, author = {Berkesi, Márta and Spránitz, Tamás and Hencz, Mátyás and Békési, Eszter and Porkoláb, Kristóf}, journal-iso = {FIZIKAI SZEMLE}, journal = {FIZIKAI SZEMLE}, volume = {73}, unique-id = {34402078}, issn = {0015-3257}, year = {2023}, pages = {343-345}, orcid-numbers = {Berkesi, Márta/0000-0003-4380-057X; Spránitz, Tamás/0000-0002-5086-3133; Hencz, Mátyás/0000-0001-9716-5714; Békési, Eszter/0000-0003-3561-1656; Porkoláb, Kristóf/0000-0001-7470-8296} } @article{MTMT:34210603, title = {Tectonically-determined distribution of monogenetic volcanoes in a compressive tectonic regime: An example from the Pannonian continental back-arc system (Central Europe)}, url = {https://m2.mtmt.hu/api/publication/34210603}, author = {Hencz, Mátyás and Biró, Tamás and Németh, Károly and Porkoláb, Kristóf and Kovács, István János and Spránitz, Tamás and Cloetingh, Sierd and Szabó, Csaba and Berkesi, Márta}, doi = {10.1016/j.jvolgeores.2023.107940}, journal-iso = {J VOLCANOL GEOTH RES}, journal = {JOURNAL OF VOLCANOLOGY AND GEOTHERMAL RESEARCH}, volume = {444}, unique-id = {34210603}, issn = {0377-0273}, abstract = {This paper presents the results from a geographic information systems (GIS) workflow, which was used to analyze the spatial distribution and temporal evolution of volcanoes in the Mio-Pleistocene monogenetic Bakony-Balaton Highland Volcanic Field (BBHVF), located in the Pannonian Basin, Hungary. Volcanism occurred during the tectonic inversion in a back-arc setting and a compressive/transpressive tectonic regime on the hottest and thinnest lithosphere of continental Europe. The main goal of this study is to clarify the effect of the pre-existing structure of the upper lithosphere in the distribution of the volcanic centers across the volcanic field using an innovative GIS methodology. Orientation of the volcanic field was compared to the orientation of the faults in the BBHVF, and in its larger vicinity, which resulted in correspondence, suggesting the dominance of the SW-NE direction. The directions of the volcanic lineaments fit well to the two main fault directions. The fault-volcano proximity analysis suggests that the fault plane of a thrust fault was an important structural feature during the lifespan of the volcanism. All results suggest that the fault plane of a regionally significant Cretaceous thrust fault (Litér Fault) might have likely served as a temporary pathway for the ascending magma, whereby (similarly to other, smaller faults) redirecting the magmas causing clustering of the volcanoes. This highlights the importance of major upper crustal structural heterogeneities for magma transport in a compressive tectonic system, especially in the case of active, monogenetic volcanic fields from a volcanic hazard perspective. The present GIS workflow can be effective in analyzing the spatial patterns of the volcanism and its connection with crustal structures at monogenetic volcanic fields worldwide.}, keywords = {GIS; FAULT; monogenetic; lithosphere; compression; Bakony-Balaton Highland; lineament}, year = {2023}, eissn = {1872-6097}, pages = {107940-107958}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Porkoláb, Kristóf/0000-0001-7470-8296; Spránitz, Tamás/0000-0002-5086-3133; Szabó, Csaba/0000-0002-1580-6344; Berkesi, Márta/0000-0003-4380-057X} } @mastersthesis{MTMT:34002495, title = {A bükkaljai szilíciumgazdag piroklasztitok rétegtana, fizikai vulkanológiája,paleomágneses és geokémiai tulajdonságai}, url = {https://m2.mtmt.hu/api/publication/34002495}, author = {Hencz, Mátyás}, doi = {10.15476/ELTE.2022.052}, publisher = {Eötvös Loránd University}, unique-id = {34002495}, year = {2022}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714} } @{MTMT:33533651, title = {Integrating field volcanology, paleomagnetism and structural geology to correlate a poorly preserved Miocene succession in the East Mátra Mts.

Welded ignimbrites are usually resistant to erosion, thus, they often appear as positive landforms, i.e., mesas or tilted plateaus after millions of years of denudation. The Bükkalja Volcanic Area being part of the most extended foothill area of the North Hungarian Mountains, is composed predominantly of Miocene ignimbrites, where the frequency distributions of elevation a.s.l., slope, aspect, as well as topographic openness, were investigated using a 30 m resolution SRTM-based digital surface model at four sample areas located at different relative distances from the assumed source localities of the ignimbrites, showing both non-welded and welded facies. The degree of dissection was also examined along swath profiles. The topography of the sample area closest to the source localities is dominated by slabs of moderately dissected welded ignimbrites, gently dipping towards SE. Farther away from the source the topography is dominated by erosional valleys and ridges, resulting in a narrower typical elevation range, a higher proportion of pixels with greater than 5° slope, higher frequencies of NE and SW exposures, and more significant incision resulted in more frequent pixels with positive topographic openness less than 1.5 radians here. Higher thicknesses and emplacement temperatures of ignimbrites, often showing welded facies are more common closer to the source vent. Thus, the erosional pattern around calderas can be used to draw conclusions on the spatial extent of the most intense ignimbrite accumulation, i.e., the location of eruption centres even in highly eroded ignimbrite fields.}, year = {2022}, eissn = {2064-5147}, pages = {213-229}, orcid-numbers = {Biró, Tamás/0000-0001-5198-7210; Hencz, Mátyás/0000-0001-9716-5714; Telbisz, Tamás Ferenc/0000-0003-4471-2889; Karátson, Dávid/0000-0003-0386-1239} } @{MTMT:33116922, title = {Ipolytarnóc: egy 17,2 millió évvel ezelőtti, vei ≥ 7 robbanásos vulkánkitörés eseménysztratigráfiája}, url = {https://m2.mtmt.hu/api/publication/33116922}, author = {Karátson, Dávid and Biró, Tamás and Portnyagin, M and Kiss, Balázs and Paquette, JL and Cseri, Zoltán and Hencz, Mátyás and Németh, Károly and Lahitte, P and Mártonné, Szalay E and Kordos, L and Józsa, Sándor and Hably, L and Müller, S and Szarvas, I}, booktitle = {Calce et malleo – Mésszel és kalapáccsal}, unique-id = {33116922}, year = {2022}, pages = {64-66}, orcid-numbers = {Karátson, Dávid/0000-0003-0386-1239; Biró, Tamás/0000-0001-5198-7210; Kiss, Balázs/0000-0003-0040-0656; Hencz, Mátyás/0000-0001-9716-5714; Józsa, Sándor/0000-0001-8219-0044} }
