A series of ecostratigraphic events across the Langhian/Serravallian boundary in an epicontinental setting: the northern Pannonian Basin

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

“…Agnini et al, 2017). Despite the significant error in the MO-2 fine tuff, the obtained 40 Ar/ 39 Ar age data are consistent with biostratigraphic ranking of volcaniclastic samples (Figure 12; Csibri et al, 2018;Holcová et al, 2019;Kováč et al, 2018;Rybár et al, 2015Rybár et al, , 2016Šarinová, Hudáčková, et al, 2021;Zlinská, 2016). The reason that fine tuffs do not provide sufficiently accurate 40 Ar/ 39 Ar single-grain data are due to the absence of stable minerals with high K content (sanidine) and the small crystal size of the measured minerals with low K content (plagioclase and amphibole; Data S1).…”

“…In the Danube Basin, pyroclastic rocks as well as reworked volcanic material were deposited dominantly in marine environment (e.g. Csibri et al, 2018;Holcová et al, 2019;Kováč et al, 2018;Rybár et al, 2015Rybár et al, , 2016Šarinová et al, 2018;Vass, 2002; this study). However, based on the geo-seismic lines (Figures 10a,b and 11a,b), the Kráľová stratovolcano created positive structure, and erosion continued up to the onset of Pannonian shelf-break slope strata.…”

“…However, the sedimentary record of Danube Basin generally starts during lower Badenian (Langhian ‐ around 15 Ma; e.g. Csibri et al., 2018; Holcová et al., 2019; Kováč et al., 2018; Rybár et al., 2015, 2016; Šarinová, Hudáčková, et al., 2021; Vlček, Hudáčková, et al., 2020), and its volcanism consist of dominantly andesite to latite (trachyandesite) rocks, although trachyte and alkali basalt are also present (Harangi et al., 1995, 2015; Lexa et al., 2010; Martin & Németh, 2004; Pánisová et al., 2018; Wijbrans et al., 2007; Zelenka et al., 2004). Simlarly, the following volcanic fields which form northeastern margin of Danube Basin: Börzsöny‐Visegrád‐Pilis‐Burda and Central Slovakia Volcanic Fields (BVPBF and CSVF respectively; Lexa et al., 2010) are built by dominantly andesite volcanism with an age range app.…”

The Central Paratethys Sea—rise and demise of a Miocene European marine biodiversity hotspot

“…The predominance of planktotrophic larval types persisted from the MCO through the MMCT. The reason for this might have been the increase in productivity in Paratethyan surface waters during the Serravallian 63 , 65 , 66 , which supported planktotrophy. Similarly, Landau et al 67 documented that productivity promoted planktotrophic development in the Caribbean Neogene.…”

“…During the Langhian, Paratethyan surface waters were connected to the Proto-Mediterraean Sea via strong current systems and upwelling systems were wide-spread 63 , 64 . This situation favored planktotrophy.…”
