The mineral cargo of dacitic pumices enables us to constrain the conditions of the pre-recharge crystal mush, the recharge magmas and the post-recharge magma prior to eruptions. A careful evaluation of the results yielded by various thermometers, barometers, oxybarometers, chemometers and hygrometers as well as direct comparison with experimental data were necessary to select the appropriate techniques and therefore to constrain the conditions for the Ciomadul magmatic system. Beneath the volcano, a felsic crystal mush body is inferred at 8–12 km depth comprising slightly oxidized (0.5–1.6 ∆NNO), low-temperature (680–750 °C), highly crystalline magma. This zone is underlain by a deep magma storage zone with less evolved, hot (> 900 °C) magma at 16–40 km depth. The dominantly explosive volcanism after the effusive eruptions (160–90 ka) can be explained by the ascent of distinct recharge magmas. They contained high-Mg (MgO > 18 wt%) amphibole, which could have crystallized from ultrahydrous (H 2 O > 8 wt%) magma at near-liquidus conditions. The rates of amphibole overgrowth and microphenocryst formation require weeks to months for the magma mixing and the eruption events. The hybridized melt became more oxidized and contained dissolved water in around 5.5 wt% at temperature of 790–830 °C calculated from the re-equilibrated Fe-Ti oxides. These magma properties along with the degree of crystallinity (27–38 vol% crystals) favored rapid magma ascent and an explosive style eruption. Thus, the strongly hydrous nature of the recharge magma in addition to the crystallinity and H 2 O content of the pre-eruption magma plays an important role in controlling the eruption style.}, year = {2023}, eissn = {1432-0967}, orcid-numbers = {Szemerédi, Máté/0000-0002-7432-8418; Harangi, Szabolcs/0000-0003-2372-4581; Erdmann, S/0000-0002-1083-9251; Bachmann, O/0000-0003-2952-3465; Seghedi, I/0000-0001-7381-7802; Virág, Attila/0000-0002-5530-0065; Ntaflos, T/0000-0001-6665-5868; Molnár, Kata/0000-0001-6993-5806; Haranginé Lukács, Réka/0000-0002-2338-4209} } @{MTMT:34342977, title = {Paleozoikum}, url = {https://m2.mtmt.hu/api/publication/34342977}, author = {Halász, Amadé and Haranginé Lukács, Réka and Koroknai, B and Less, György and Raucsikné Varga, Andrea Beáta and Lelkesné Felvári, Gy and Józsa, Sándor and Kovács, Sándor and Király, Edit and Benkó, Zsolt and Majoros, Gy and Pentelényi, L and Szederkényi, T and Rálischné Felgenhauer, E and Pelikán, P and Szemerédi, Máté and Konrád, Gy and Barabásné Stuhl, Á and Pál-Molnár, E}, booktitle = {Magyarország litosztratigráfiai egységeinek leírása I.}, unique-id = {34342977}, year = {2023}, pages = {43-112}, orcid-numbers = {Halász, Amadé/0000-0003-4582-8883; Haranginé Lukács, Réka/0000-0002-2338-4209; Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482; Józsa, Sándor/0000-0001-8219-0044; Szemerédi, Máté/0000-0002-7432-8418} } @CONFERENCE{MTMT:34230625, title = {Petrographic traces of open-system magmatic processes in the felsic suite of the Ditrău Alkaline Massif (Eastern Carpathians, Romania)}, url = {https://m2.mtmt.hu/api/publication/34230625}, author = {Kiri, Luca and Szemerédi, Máté and Pál-Molnár, Elemér}, booktitle = {EGU General Assembly 2023: Abstracts}, unique-id = {34230625}, year = {2023}, orcid-numbers = {Szemerédi, Máté/0000-0002-7432-8418; Pál-Molnár, Elemér/0000-0002-9606-0133} } @article{MTMT:34226512, title = {Bulk-rock and mineral-scale geochemical evidence of open-system magmatic processes in the felsic rocks of the northern part of the Ditrău Alkaline Massif (Eastern Carpathians, Romania)}, url = {https://m2.mtmt.hu/api/publication/34226512}, author = {Kiri, Luca and Szemerédi, Máté and Saskia, Erdmann and Batki, Anikó and Pál-Molnár, Elemér}, doi = {10.31577/GeolCarp.2023.20}, journal-iso = {GEOL CARPATH}, journal = {GEOLOGICA CARPATHICA}, volume = {74}, unique-id = {34226512}, issn = {1335-0552}, year = {2023}, eissn = {1336-8052}, pages = {297-323}, orcid-numbers = {Szemerédi, Máté/0000-0002-7432-8418; Pál-Molnár, Elemér/0000-0002-9606-0133} } @CONFERENCE{MTMT:34194491, title = {Trace elements and zircon ages to unravel Late Palaeozoic igneous episodes and Variscan geodynamic processes in the Tisza Mega-unit (Carpathian–Pannonian region)}, url = {https://m2.mtmt.hu/api/publication/34194491}, author = {Szemerédi, Máté and Raucsikné Varga, Andrea Beáta and Haranginé Lukács, Réka and Dunkl, I and Seghedi, I and Kovács, Zoltán and Raucsik, Béla and Harangi, Szabolcs and Kosztolányi, É and Pál-Molnár, Elemér}, booktitle = {Goldschmidt 2023 Conference: abstracts}, unique-id = {34194491}, year = {2023}, orcid-numbers = {Szemerédi, Máté/0000-0002-7432-8418; Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482; Haranginé Lukács, Réka/0000-0002-2338-4209; Raucsik, Béla/0000-0002-1951-5974; Harangi, Szabolcs/0000-0003-2372-4581; Pál-Molnár, Elemér/0000-0002-9606-0133} } @{MTMT:34161474, title = {Variszkuszi, S-típusú granitoidok a Codru-takarórendszerben (Erdélyi-khg.): a Galsai pluton kőzettani-geokémiai vizsgálata és korrelációja a Tiszai-főegységben}, url = {https://m2.mtmt.hu/api/publication/34161474}, author = {Jákri, B and Szemerédi, Máté and Dunkl, I and Kovács, Zoltán and Pál-Molnár, Elemér}, booktitle = {13.
