Tracing widespread Early Miocene ignimbrite eruptions and petrogenesis at the onset of the Carpathian-Pannonian Region silicic volcanism

Insights into the palaeoenvironments, structure and stratigraphy of the lower Miocene of the Eastern Carpathians Bend Zone, Romania

“…The pyroclastic suite at Ipolytarnóc (North Hun gary), ~75 km away from the prox i mal BVF de posit, also has a sim i lar zir con U-Pb and 40 Ar/ 39 Ar age and zir con trace el e ment com posi tion to the Eger ignimbrite as shown by Lukács et al (2021), Šarinová et al (2021) and Karátson et al (2022). Brlek et al (2023) iden ti fied the Eger erup tion-re lated ignimbrite in the Mt. Kalnik (Croatia) and fall de pos its in the Sinj Ba sin (Croatia), based on zir con U-Pb dat ing, glass and zir con geo chem is try.…”

“…Lukács et al (2018) iden ti fied four main early Mio cene ignimbrite-form ing explo sive erup tions in the Bükkalja Vol ca nic Field, north ern Hungary; these are the Csv-2 ignimbrite at 18.2 ±0.3 Ma, the Eger ignimbrite at 17.5 ±0.3 Ma, the Mangó ignimbrite at 17.065 ±0.014 Ma and the Bogács ignimbrite at 16.816 ±0.059 Ma. Recently, Karátson et al (2022) and Brlek et al (2023) re fined the age of the Eger erup tion event to 17.3 Ma and the Csv-2 (named as Wind/Kalnik) erup tion to 18.1 Ma with <100 ky uncer tain ties. The thick Bãtrâni Tuff from the ECBZ rep re sents the prod uct of one such erup tion, which pro vides in di ca tion of a pos si ble large ex plo sive vol ca nic event.…”

Middle Miocene volcanic flare up preceding and synchronous with the Langhian/Serravallian sea‐level decline in the North Pannonian Basin: Insights from 40Ar/39Ar dating, geo‐seismic analysis and 3D visualization of the subterranean Kráľová stratovolcano

“…These data allow to improve the statement about genetic evolution and also estimates of the extent and strength of eruptions (e.g. Brlek et al., 2023; Karátson et al., 2022). With respect to basin analysis these data enable the calibration of other dating methods, and they permit dating of significant events in basin evolution including palaeoenvironmental conditions and palaeontology (e.g.…”

“…Although during the subduction event the significant volcanism was not present due to the overall compressive stress field and the presence of a thick crust and lithosphere, at that time the mantle lithosphere was supplied with various subduction components (Harangi & Lenkey, 2007; Lexa et al., 2010; Pécskay et al., 2006; Seghedi et al., 2004; Seghedi & Downes, 2011). Magmas reached the surface at the beginning of subduction‐retreat back‐arc extension connected with translation and rotation of ALCAPA and Tisa‐Dacia microplates (Brlek et al., 2023; Harangi & Lenkey, 2007; Konečný et al., 2002; Lexa et al., 2010; Lukács et al., 2018; Pécskay et al., 1995, 2006; Schmid et al., 2008; Seghedi et al., 2004; Seghedi & Downes, 2011; Zelenka et al., 2004). The formation of extensional basins took place over several tectonic periods, which were accompanied by different volcanic activity (Fodor et al., 2021; Harangi & Lenkey, 2007; Horváth et al., 2015; Lexa & Konečný, 1998; Lukács et al., 2018; Pécskay et al., 1995, 2006; Seghedi et al., 2004; Seghedi & Downes, 2011; Šujan et al., 2021).…”

“…In present time, thanks to this development, many workers in CPR are devoted to inquiry about radioisotope age data from altered pyroclastic rocks; to the age refinement of volcanic stages; as well as to the correlation of products of volcanic activity in time and space (e.g. Badurina et al., 2021; Bojar et al., 2018; Brlek et al., 2020, 2023; Bukowski et al., 2018; de Leeuw et al., 2010, 2018; Karátson et al., 2000, 2007; Lukács et al., 2015, 2018, 2021; Marković et al., 2021; Pálfy et al., 2007; Roetzel et al., 2014; Rybár et al., 2019; Sant et al., 2019, 2020; Šarinová, Hudáčková, et al., 2021; Šarinová, Rybár, et al., 2021; Šegvić et al., 2023; Śliwiński et al., 2012; Wijbrans et al., 2007). These data allow to improve the statement about genetic evolution and also estimates of the extent and strength of eruptions (e.g.…”
