This research developed a new conceptual model of detailed geologic geometry by integrating 133 well-logs, 366 hydrodynamic data and 118 water samples. As new results, systematic 3D log correlation detected four distinct hydrostratigraphic units in the Southern Nyírség–Hajdúság Groundwater Body (East Hungary). The primary aquifer was identified as an incised valley 10–13 km wide and a NE–SW strike. Logan’s approach estimated the average hydraulic conductivity of the Incised Valley Unit (IVU) at 11 m/d, higher than the other three aquifers (3.2 m/d to 4.6 m/d). The average specific capacity of wells screening the IVU is 315.6 m3/d/m, in contrast with the remaining aquifers ranging from 31.6 m3/d/m to 92 m3/d/m. Pressure–depth profiles, dynamic pressure increment and hydraulic head maps revealed recharge–discharge zones and hydraulic windows between hydrostratigraphic units. The elongated pattern on the hydraulic head map at the depth of the IVU showed the existence of a preferential path along its axis within the mapped borders of the IVU. Hydrochemical analysis revealed Ca-Mg-HCO3 water type within the primary aquifer and Na-HCO3 water type in the laterally connected aquifer. The saturation index values indicated a transition from undersaturated to supersaturated state inside the main aquifer for calcite and dolomite minerals. The correlation matrix and PCA results demonstrated that the carbonate weathering process is the main factor controlling the groundwater chemistry. This integrated approach holds significance for future applications of the regional conceptual model in water management planning, sustainable aquifer development and contaminant transport modelling. It provides essential contributions to informed decision-making and the formulation of effective strategies, ensuring the long-term availability and utilization of groundwater resources.}, keywords = {Conceptual model; Groundwater modeling; incised valley aquifer; geologic geometry}, year = {2023}, eissn = {2073-4441}, orcid-numbers = {Flores Carpio, Yetzabbel Gerarda/0000-0003-0365-8951; Szanyi, János/0000-0002-8053-6360} } @article{MTMT:34001105, title = {Obliquity-driven mountain permafrost-related fluvial magnetic susceptibility cycles in the Quaternary mid-latitude long-term (2.5 Ma) fluvial Maros Fan in the Pannonian Basin}, url = {https://m2.mtmt.hu/api/publication/34001105}, author = {Püspöki, Zoltán and Gibbard, P.L. and Kiss, László Ferenc and McIntosh, Richard William and Thamó-Bozsó, E. and Krassay, Z. and Szappanos, B. and Maigut, V. and Kovács, Péter Gábor and Karácsony, Dominik Ádám and Stercel, F. and Visnovitz, Ferenc and Demény, K. and Bereczki, L. and Szőcs, T. and Rotár-Szalkai, Á. and Fancsik, Tamás}, doi = {10.1111/bor.12618}, journal-iso = {BOREAS}, journal = {BOREAS}, volume = {52}, unique-id = {34001105}, issn = {0300-9483}, abstract = {Magnetic susceptibility (MS) of the Quaternary long-term mid-latitude Maros fluvial fan (Pannonian Basin) was recorded to understand the stratigraphical features of source-proximal fluvial depositional settings. Three fully cored 500-m-deep boreholes were sampled at 0.5-m intervals; low-field and frequency dependent MS were measured, and complementary hysteresis and SEM-EDAX investigationswere performed on selected samples. Logged susceptibility data were also used to log correlations established by a simultaneous comparison of wireline log and laboratory measurements. Time-series analyses of the susceptibility records reveal a ∼41-ka and ∼100-ka cyclicity. Towards the source-distal sections the intensity of the ∼41-ka cycles decreases, while that of the ∼100-ka cycles remains strong. Stratigraphical and spectral similarities were observed between the Maros fluvial fan and Chinese loess records; however, based on complementary magnetic data, the magnetic phase of the Maros Fan sections is related to the detrital magnetite that originates from the catchment during early postglacial permafrost degradations. The amplification of the ∼41-ka cycles can be attributed to the very high susceptibility values in source-proximal settings and to the special stratigraphical feature of the distributive fluvial systems. This comprises the increased avulsion frequency on the fluvial fans in ‘glacial recession periods’, in concert with the ‘early postglacial’ occurrence of the permafrost-related magnetite originating from the catchment. As a local phenomenon, this is significant since it records the obliquity-driven variations in permafrost development in a catchment. However, fluvial and alluvial fans are widespread depositional landforms within the Eurasian mountain range and were possibly the same during the Quaternary deglaciations. Thus, obliquity-driven magnetic susceptibility variations in source-proximal fan deposits attached or adjacent to regions of loess deposition should also be considered when scanning for potential source material of aeolian deposits.}, year = {2023}, eissn = {1502-3885}, pages = {402-426}, orcid-numbers = {Visnovitz, Ferenc/0000-0002-7040-0080} } @inproceedings{MTMT:33037526, title = {HYDROGEOLOGIC MODELLING OF HAJDÚSZOBOSZLÓ AQUIFER SYSTEM TO DEMONSTRATE THE IMPORTANCE OF GEOLOGICAL HETEROGENEITY SPATIAL DISTRIBUTION OVER THE FLOW PATHS}, url = {https://m2.mtmt.hu/api/publication/33037526}, author = {Flores Carpio, Yetzabbel Gerarda and Szűcs, Péter and Püspöki, Zoltán}, booktitle = {International Doctoral Seminar 2022}, unique-id = {33037526}, year = {2022}, pages = {59-72}, orcid-numbers = {Flores Carpio, Yetzabbel Gerarda/0000-0003-0365-8951} } @{MTMT:32708912, title = {LONG TERM PANNONIAN FLUVIAL MAGNETIC SUSCEPTIBILITY RECORDS DOCUMENTING ALPINE PERMAFROST DEVELOPMENT IN COLD EVENTS OF THE EUROPEAN QUATERNARY}, url = {https://m2.mtmt.hu/api/publication/32708912}, author = {Püspöki, Zoltán and Philip, Leonard Gibbard}, booktitle = {Quaternary stratigraphy – palaeoenvironment and humans in Eurasia: INQUA SEQS 2021 Conference proceedings}, unique-id = {32708912}, year = {2021}, pages = {93-94} } @article{MTMT:31950068, title = {Fluvial magnetic susceptibility as a proxy for long‐term variations of mountain permafrost development in the Alp‐Carpathian region}, url = {https://m2.mtmt.hu/api/publication/31950068}, author = {Püspöki, Zoltán and Gibbard, PL and Nádor, A and Thamóné Bozsó, Edit and Sümegi, Pál and Fogarassy-Pummer, Tímea and McIntosh, Richard William and Lantos, M and Tóth‐Makk, Á and Stercel, F and Krassay, Z and Kovács, Péter Gábor and Szőcs, Teodóra and Fancsik, Tamás}, doi = {10.1111/bor.12520}, journal-iso = {BOREAS}, journal = {BOREAS}, volume = {50}, unique-id = {31950068}, issn = {0300-9483}, keywords = {földtan}, year = {2021}, eissn = {1502-3885}, pages = {806-825}, orcid-numbers = {Püspöki, Zoltán/0000-0002-8282-7620;

Low field magnetic susceptibility (MS) was measured in four boreholes from the basin centre and margins, representing channel and flood-plain environments. Statistical distributions of MS data contain significant sets of outliers, regardless of facies conditions. The downhole distribution of these outliers produces magnetic susceptibility cycles. Supported by magnetic susceptibility cycles, high-resolution facies correlations were performed reflecting a steady palaeohydrographical situation in the area, with a trunk river to the southeast and tributaries to the northwest. SEM-EDX data revealed that ferromagnetic grains are responsible for the outlying MS values. The heterogeneous association of magnetite indicates a catchment area with volcanic and metamorphic rocks, while the group of small (<5 mu m) magnetite octahedrons originated from nearby rhyolitic tuff formations. Magnetic grains were transported along channel belts, while small (<2 mu m) magnetic particles were floated onto flood-plains attached to clays. Climatic control is indicated by peaks at similar to 100 ka frequency in spectra of MS records and was also detected in palaeosol development and in flood frequency using the spectra of measured colour (similar to 100 ka) and logged resistivity (similar to 100 ka, similar to 41 ka), respectively. The climate-dependent MS signal traceable far into the basin in both channel and flood-plain environments can be summoned when the Quaternary fluvial succession of the Pannonian Basin is investigated, assuming some sources of magnetite in the catchment areas. According to the concept of 'fluvial magnetic susceptibility episodes', the early postglacial escape and spreading of the magnetite fraction control the MS signal that can support mapping of the unconformable Quaternary base and building of high-resolution models of aquifers.}, keywords = {Magnetic susceptibility; Jászság; geológia; földtan}, year = {2020}, eissn = {1502-3885}, pages = {181-199}, orcid-numbers = {Márton Péterné Szalay, Emőke/0000-0002-2135-8867} } @techreport{MTMT:31991815, title = {Jelentés az ivó és öntözővizes rétegsor nagy felbontású fácies korrelációs vizsgálatairól debrecen-dél területen különös tekintettel a hidrodinamikai és transzportmodellek gyakorlati szempontjaira}, url = {https://m2.mtmt.hu/api/publication/31991815}, author = {Fogarassy-Pummer, Tímea and Markos, Gábor and Gál, Nóra Edit}, editor = {Püspöki, Zoltán}, unique-id = {31991815}, keywords = {geológia; földtan}, year = {2019}, pages = {1-50} }
