These processes in collaboration with old Jurassic and quaternary sediments create a diverse geological and geomorphological constructions forming the abiotic environment of areas surrounding Port Jackson and Fletcher Bay. These two locations have been chosen as two main campsites of the north Coromandel Peninsula, which are maintained by the Department of Conservation (DOC) of Coromandel Peninsula. Hence, the campsites should be considered as main places for camping for the trips of different purposes. They provide an access costal way and/or trails leading to the main geologically important locations presenting some knowable features like Pinnacles and Sugar Loaf spread through the region. To highlight these locations of interests, “geosites,” we developed qualitative-quantitative assessment of geodiversity for geosite recognition based on 8-m DEM and 1:1250,000 scale geological map and QGIS (3.28 “Firenze”) software. The methodology utilizing 8-point evaluation system applied for geological formations of the studied region and its multiplication with morphological slope degree. The result of assessment has been expanded and justified with geological, cultural, and geomorphological database acquired from literature review and direct field trips of the studied areas. The conclusion demonstrates the main geological knowledge of recognized geosites together with description of drawbacks and possible obstacles for tourism and education in the region of the northern Coromandel Peninsula.}, year = {2024}, eissn = {1867-2485}, pages = {19} } @article{MTMT:34558899, title = {A jelenkori felmelegedés lehetséges hatótényezőiről • On the Potential Drivers of Current Global Warming}, url = {https://m2.mtmt.hu/api/publication/34558899}, author = {Szarka, László Csaba}, doi = {10.1556/2065.185.2024.2.8}, journal-iso = {MAGYAR TUDOMÁNY}, journal = {MAGYAR TUDOMÁNY}, volume = {185}, unique-id = {34558899}, issn = {0025-0325}, abstract = {E tanulmány összefoglalja egy 2021 augusztusában megjelent – a jelenlegi felmelegedés statisztikailag kimutatható hatótényezőit elemző – publikáció eredményeit, nemzetközi fogadtatását, valamint a vitákban felmerült kérdések alapján elvégzett és a nemzetközi folyóiratokban közzétett új vizsgálatok tudományos következtetéseit. A cikk ellentmond az IPCC (Intergovernmental Panel on Climate Change) magabiztos állításának, miszerint természetes változások nem magyarázhatják a jelenlegi klímaváltozást. A kiterjesztett elemzések megerősítették az eredeti 2021-es eredményeket. Ezek szerint az IPCC állítása csak abban az esetben lehet megalapozott, ha (1) a napsugárzási idősor valóban olyan csekély változékonyságú, mint amilyennek az IPCC feltételezi, valamint, ha (2) a szárazföldi felszínhőmérsékleti idősorban az idővel elvárosiasodó meteorológiai állomásoknak csakugyan nincs torzító hatásuk. Bármennyire is nem akarja az IPCC hivatalosan tudomásul venni, a tudományos szakirodalomban számos olyan nagy változékonyságú napsugárzási idősor létezik, amelyek képesek lényegileg megmagyarázni a csak vidéki jellegű meteorológiai állomásokra korlátozódó hőmérsékleti idősor oszcillációit, egészen 1850-ig visszamenően. Sajnos nem tudni biztosan, hogy melyik napsugárzási idősor áll a legközelebb a valósághoz. Valójában az is valószínűtlen, hogy akármilyen gondos statisztikai elemzés elvezethet az okok feltárásához. Az viszont biztos, hogy a tudománynak sokkal mélyebben kellene foglalkoznia mindenféle természeti (Nap–Föld) változás megfigyelésével és számszerűsítésével. This paper summarizes the results of a paper published in August 2021, its international reception, and the scientific conclusions of new studies based on the issues raised in the debate and published in international journals. The article contradicts the IPCC’s (Intergovernmental Panel on Climate Change) confident assertion that natural changes cannot explain current climate change. Extended analyses confirmed the original 2021 results. These suggest that the IPCC’s claim can only be substantiated if (1) the solar radiation time series indeed has such low variability, as the IPCC assumes, and (2) if meteorological stations that have become more urbanized over time do not have a distorting effect on the land surface temperature time series. As much as the IPCC may not want to officially acknowledge it, there are a number of highly variable solar radiation time series in the scientific literature that can substantially explain the oscillations in the temperature time series, limited to rural meteorological stations, going back to 1850. Unfortunately, it is not known for sure which solar radiation time series is the closest to the real one. Indeed, it is unlikely that any careful statistical analysis can lead to the discovery of the causes. What is certain, however, is that science should be much more deeply engaged in observing and quantifying all kinds of natural (Sun–Earth) changes.}, year = {2024}, eissn = {1588-1245}, pages = {244-259} } @article{MTMT:34528699, title = {Mid-Miocene silicic explosive volcanism of the Tokaj Mts., eastern-central Europe: Eruption chronology, geochemical fingerprints and petrogenesis}, url = {https://m2.mtmt.hu/api/publication/34528699}, author = {Haranginé Lukács, Réka and Guillong, M and Szepesi, János and Szymanowski, D and Portnyagin, M and Józsa, Sándor and Bachmann, O and Petrelli, M and Müller, S and Schiller, D and Fodor, László and Chelle-Michou, C and Harangi, Szabolcs}, doi = {10.1016/j.gr.2024.01.004}, journal-iso = {GONDWANA RES}, journal = {GONDWANA RESEARCH}, volume = {130}, unique-id = {34528699}, issn = {1342-937X}, year = {2024}, eissn = {1878-0571}, pages = {53-77}, orcid-numbers = {Haranginé Lukács, Réka/0000-0002-2338-4209; Józsa, Sándor/0000-0001-8219-0044; Harangi, Szabolcs/0000-0003-2372-4581} } @article{MTMT:34528126, title = {Archeogeophysical application of non-traditional geoelectric arrays. a case study in a north-east Hungary site}, url = {https://m2.mtmt.hu/api/publication/34528126}, author = {Kárpi, Marcell and Baracza, Mátyás Krisztián and Szalai, Sándor}, doi = {10.47833/2024.1.ENG.001}, journal-iso = {GRADUS}, journal = {GRADUS}, volume = {11}, unique-id = {34528126}, abstract = {With the continuous development of multielectrode geoelectrical tomography (ERT) as a geophysical technique, we became able to detect small size targets. In this paper, we present ERT interpretation results obtained at an archaeological site in Szendrő village in northeastern Hungary, where a 17th century fortress once stood. Several historical notes and a collapsed entrance recall the existence of tunnels under the fortress and a water well of uncertain depth. To detect these structures, geoelectrical multielectrode measurements were carried out using conventional and quasi-null arrays. The quasi-null array applies the arrangement of the current (A and B) and potential electrodes (M and N) in a special way, i.e., the electrodes A, M, B, N follow each other in line in special distances from each other. The horizontal sensitivity of the resistivity profiling method using these types of arrays has been proven to be better than that of the Wenner or other conventional arrays. The comparative study aims not just to investigate the archeological features, but to test the sensitivity of the non-traditional quasi-null arrays to these two-dimensional inhomogeneities. As a result, the optimal array can be chosen, and the identification and delineation of shallow structures can be made more reliably.

Here, we present the first in situ characterization of fluids and their trace-element compositions in natural carbonatite systems by studying secondary quartz-hosted fluid inclusions from Oldoinyo Lengai volcano. 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:34485866, title = {Geomorfositios de interés geoturístico del volcán monogenético Tajogaite, erupción de 2021 (La Palma, Islas Canarias, España)}, url = {https://m2.mtmt.hu/api/publication/34485866}, author = {Dóniz-Páez, Javier and Becerra-Ramírez, Rafael and Németh, Károly and Gosálvez, Rafael U. and Escobar, Estela}, doi = {10.22201/igeof.2954436xe.2024.63.1.1731}, journal-iso = {GEOFIS INT}, journal = {GEOFISICA INTERNACIONAL}, volume = {63}, unique-id = {34485866}, issn = {0016-7169}, abstract = {Las Islas Canarias (España) son un conjunto de islas volcánicas oceánicas localizadas en la placa africana y en la latitud subtropical.

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} }
