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:34015455, title = {Anthropic Vulnerability of a Hydrothermal Mineral Deposit and Related Mining Heritage, a Case Study from a Medieval Gold-Silver Mining Area, Telkibánya, Hungary}, url = {https://m2.mtmt.hu/api/publication/34015455}, author = {Szepesi, János and Sütő, László and Novák, Tibor József and Szepesi, Éva Zsuzsanna and Benkó, Zsolt and Gruber, Péter and McIntosh, Richard William and Harangi, Szabolcs and Haranginé Lukács, Réka}, doi = {10.1007/s12371-023-00853-6}, journal-iso = {GEOHERITAGE}, journal = {GEOHERITAGE}, volume = {15}, unique-id = {34015455}, issn = {1867-2477}, abstract = {The movable geoheritage elements (minerals, fossils, rocks) are important part of geodiversity.

The aim of this study is to investigate a medieval mining site of the Carpathians (Telkibánya, Hungary) where recent anthropic vulnerability related to mineral collecting. Earlier works emphasized the scientific, aesthetic, and geo-educational potential of the mineral association and mining heritage of the study area. Our field survey gives a review of medieval mining works and the current state of the surviving infrastructure identifies the major areas of mineral collecting disturbances and the integrity of the main and additional geological elements.

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} } @article{MTMT:33072474, title = {Zsolcai-halmok földtudományi vizsgálata}, url = {https://m2.mtmt.hu/api/publication/33072474}, author = {Tóth, Csaba Albert and Pethe, Mihály and Prónay, Zsolt and McIntosh, Richard William and Novák, Tibor József and Molnár, Mihály}, doi = {10.56617/tl.3150}, journal-iso = {TÁJÖKOLÓGIAI LAPOK / J LANDSCAPE ECOL}, journal = {TÁJÖKOLÓGIAI LAPOK / JOURNAL OF LANDSCAPE ECOLOGY}, volume = {20}, unique-id = {33072474}, issn = {1589-4673}, abstract = {Az Alföld északi részén, a Sajó ármentes teraszán emelkedő, 6 méter magas, régészetileg feltáratlan kettős halom vizsgálata volt a célunk, mivel korábban szinte semmilyen kutatás nem zajlott e halmokkal kapcsolatban. Ha egyenként vizsgáljuk e halmokat, akkor a közepes, átlagos méretű hazai halmok csoportjába tartoznak. Az viszont már egyáltalán nem tekinthető magyarországi viszonylatban átlagosnak, hogy két, tájképileg és növénytakaróját tekintve kiemelkedően értékes, szorosan egymás mellé épült prehisztorikus halom mai napig fennmaradt egy intenzíven átalakított kultúrtájban. A rétegtani és kőzettani elemzések alapján a Zsolcai-halmok fő építőanyaga a közeli Bükkből származó mészkő, a Szerencsi-dombságból bányászott riolittufa, a halmok lábánál kitermelt termőtalaj és talajjal kevert sárgásbarna pleisztocén löszös üledék. Mindkét halmot fél méternél nem mélyebb, gyűrűszerű mélyedés vesz körbe jelenleg, amelyek eredetileg közel három méter mély, talajvízzel töltött árkok lehettek. Ezekből termelhették ki a halomtestek magasításához szükséges építőanyagot. Az eltemetett paleotalajok radiokarbon kora alapján (cal BC 950–404 és cal BC 879–542) kijelenthető, hogy a két halom az i.e. 9-6. században épülhetett szinte teljesen egyidőben.

A mágneses anomália mérések szerint a halmoktól északra elterülő sík térszínen több szarmata körárkos sírt azonosítottunk.
