“…All these examples strengthen the observation (e.g. Balázs et al, ) that the early Late Miocene was a tectonically active period, when rifting renewed, or even accelerated, particularly in the eastern basin part where core‐complex extension was also claimed (Seghedi & Downes, ). As an expression of this late‐stage rifting, earliest Late Miocene volcanism was coeval with the fastest subsidence of the Polgár Trough (11.6–9.78 Ma: 1,300 m).…”

“…This led to the birth of the Lake Pannon (~11.6 Ma), a large isolated lake with a lifetime of 7 million years (Magyar et al, ; Magyar, Geary, & Müller, ). The formation of this lake was coeval with the onset of the post‐rift thermal subsidence that was, however, time‐transgressive and started earlier (~12 Ma) in the south‐western and progressively later (~10–9 Ma) in the north‐eastern part of the basin (Balázs et al, ; Horváth et al, ). In parallel to the infilling of the lake, the Pannonian Basin was inverted from the Pliocene onward due to the plate reorganisations (Bada et al, ; Dombrádi, Sokoutis, Bada, Cloetingh, & Horváth, ).…”

Variation in style of magmatism and emplacement mechanism induced by changes in basin environments and stress fields (Pannonian Basin, Central Europe)

et al. 2018

The development of high‐resolution 3D seismic cubes has permitted recognition of variable subvolcanic features mostly located in passive continental margins. Our study area is situated in a different tectonic setting, in the extensional Pannonian Basin system (central Europe) where the lithospheric extension was associated with a wide variety of magmatic suites during the Miocene. Our primary objective is to map the buried magmatic bodies, to better understand the temporal and spatial variation in the style of magmatism and emplacement mechanism within the first order Mid‐Hungarian Fault Zone (MHFZ) along which the substantial Miocene displacement took place. The combination of seismic, borehole and log data interpretation enabled us to delineate various previously unknown subvolcanic‐volcanic features. In addition, a new approach of neural network analysis on log data was applied to detect and quantitatively characterise hydrothermal mounds that are hard to interpret solely from seismic data. The volcanic activity started in the Middle Miocene and induced the development of extrusive volcanic mounds south of the NE‐SW trending, continuous strike‐slip fault zone (Hajdú Fault Zone). In the earliest Late Miocene (11.6–9.78 Ma), the style of magmatic activity changed resulting in emplacement of intrusions and development of hydrothermal mounds. Sill emplacement occurred from south‐east to north‐west based on primary flow‐emplacement structures. The time of sill emplacement and the development of hydrothermal mounds can be bracketed by onlapped forced folds and mounds. This time coincided with the acceleration of sedimentation producing poorly consolidated, water‐saturated sediments preventing magma from flowing to the paleosurface. The change in extensional direction resulted in change in fault pattern, thus the formerly continuous basin‐bounding strike‐slip fault became segmented which could facilitate the magma flow toward the basin centre.

“…Therefore, the NCD A. torrentium populations are likely to have evolved under geographical isolation, due to the formation of the mountain range of Alps to the northwest, the Adriatic Sea in the south and southwest, and the Paratethys in the north (Figure ) and subsequently the Pannonian Lake, for a period of about 11 m.y. (Balázs et al, ). This time frame coincides with the split and diversification of the inhabiting A. torrentium NCD lineages (Figure a).…”

“…However, this process lasted for ~25 Ma (Schmid et al, ), an interval that cannot offer a specific anchor for calibration and consequently yields imprecise estimations. Therefore, the incorporation of the isolated APU population, which can be accurately tied into the well‐documented results of tectonic displacement, and the formation of a marine water flooded rift (Balázs et al, ; Magyar et al, ), has the potential to advance the knowledge toward a full understanding of the evolutionary history of the A. torrentium .…”

Crayfish can be used as model organisms in phylogeographic and divergence time studies if reliable calibrations are available. This study presents a comprehensive investigation into the phylogeography of the European stone crayfish ( Austropotamobius torrentium ) and includes samples from previously unstudied sites. Two mitochondrial markers were used to reveal evolutionary relationships among haplogroups throughout the species’ distributional range and to estimate the divergence time by employing both substitution rates and geological calibration methods. Our haplotype network reconstruction and phylogenetic analyses revealed the existence of a previously unknown haplogroup distributed in Romania's Apuseni Mountains. This haplogroup is closely related to others that are endemic in the Dinarides, despite their vast geographical separation (~600 km). The separation is best explained by the well‐dated tectonic displacement of the Tisza–Dacia microplate, which started in the Miocene (~16 Ma) and possibly carried part of the A. torrentium population to the current location of the Apuseni Mountains. This population may thus have been isolated from the Dinarides for a period of ca. 11 m.y. by marine and lacustrine phases of the Pannonian Basin. The inclusion of this geological event as a calibration point in divergence time analyses challenges currently accepted crayfish evolutionary time frames for the region, constraining the evolution of this area's crayfish to a much earlier date. We discuss why molecular clock calibrations previously employed to date European crayfish species divergences should therefore be reconsidered.

“…Following the closure of these oceanic domains the Alcapa and Tisza-Dacia units gradually occupied the Carpathian Embayment from the late Oligocene until the late Miocene (11 Ma; Kázmér and Kovács 1985;Fodor et al 1999). The extrusion of these blocks overlapped with the intensive extension of the lithosphere in the central part of the CPR of which exact driving mechanism is still disputed (Huismans et al 2001;Horváth et al 2006;Kovács et al 2012;Harangi et al 2015;Balázs et al 2016). Alcapa and TiszaDacia eventually collided with the stable European platform in the late Miocene.…”

AlpArray in Hungary: temporary and permanent seismological networks in the transition zone between the Eastern Alps and the Pannonian basin

et al. 2018

View full text Add to dashboard Cite

In the last few decades dense large-scale seismic networks showed their importance in studying the structure of the lithosphere and the upper mantle. The better understanding of the Apennines-Alps-Carpathian-Dinarides system is the main target of the AlpArray European international initiative in which more than 50 institutes are involved. The core of AlpArray is the AlpArray Seismic Network (AASN). With its $ 600 broadband seismic stations ( $ 280 of which are temporary) the AASN is, so far, the largest passive seismic experiment in Europe. The MTA CSFK Geodetic and Geophysical Institute, as a Core Member of the AlpArray project, contributes to the AlpArray Seismic Network with its entire permanent network as well as with 11 temporary broadband seismic stations deployed in Western Hungary. Three additional station equipment were provided by the Swiss-AlpArray SINERGIA program. The average station distance together with the permanent stations is around 40 km in the area of interest. The temporary network has been installed between December 2015 and July 2016 and the planned operation period is 3 years. In this paper we describe the characteristics of the 29 permanent and temporary stations, introducing not only the equipment, but the location, housing and geological setting, as well. We present median power spectral density curves in order to characterise the noise conditions at each station.
