Across the field sites we see examples of disaggregation to cataclastic DB sets and evidence of frequent reactivation by discrete faulting. Thin section analysis, cross-cutting relationships and well-defined time constraints of analysed brittle structures demonstrate that with increased burial depth, DB deformation mechanisms progressed from granular flow to cataclasis. The DB sets were classified into 10 deformation phases based on formerly published independent fault-slip analysis and structural mapping. Subsidence curves were constructed for each stratigraphic level involved in deformation and were used along with the intersection of deformation episodes to calculate the depth intervals of DB generations and subsequent structural elements. The DB formation depths obtained were transferred to the depth range of the related mechanisms. This combined methodology permits a more quantitative approach to determine the changes in the deformation mechanisms with depth. Our results show that granular flow (disaggregation bands) dominates down to 100-150 m as the earliest deformation structure, followed by weak then moderate cataclasis. The transition between weak and moderate cataclasis is at approximately 300 +/- 100 m for host rock rich in feldspar or fragile tuffitic components and from around 900 +/- 100 m in quartz-rich sediments. In addition, deformation by frictional sliding concentrates on discrete fault planes at the margin of cataclastic bands or on new fracture planes from similar to 500 +/- 100 m in volcanoclastic or feldspar rich host rocks, and 1000 +/- 100 m in quartz-rich host rocks. We suggest that burial-induced diagenetic processes is dependent on subsidence history, and partly in connection with regional fluid migration path, control the transition from moderate or advanced cataclasis to discrete fault slip. All these changes affect the pore structure and porosity that contribute to rheological changes, and hence change in deformation mechanism of coeval fracturing events.

The pre-Miocene substratum of the volcano contains Mesozoic sedimentary units in addition to the nearby exhumed igneous Recsk Complex. The Oligocene emplacement age of the Recsk Complex is constrained by zircon U-Pb geochronology to be 29.6 Ma, which serves as a benchmark for the beginning of its thermal history. All measured apatite (U-Th)/He ages (19.9-5.9 Ma) and most of the zircon (U-Th)/He ages (26.2-17.7 Ma) are considerably younger than the emplacement age of the Oligocene Recsk Complex, implying thermal overprinting by the adjacent Miocene Matra Volcano. The apatite and zircon He ages of the Oligocene complex increase from south to north, providing clear evidence of a northwards-weakening thermal overprint. The post-Oligocene thermal history of the basement was reconstructed via one-dimensional subsidence/thermal modelling. According to zircon He modelling, the thickness of the covering units above the Recsk Complex was estimated to be 1000-1500 m and the heat flux was c. 200 mW m(-2) during the Miocene volcanism. Thermal modelling based on apatite He data suggests that the Miocene volcanism was followed by intensive erosion and the exposure of the Recsk Complex by the Late Miocene.

The long-lasting magmatic activity began with some of the most voluminous silicic eruptions in Europe for the last 20 Myr. This paper describes the eruption chronology of this volcanic activity using new, high-quality zircon U-Pb dates, and provides the first estimates on the volume and areal distribution of the volcanic products, characterizes the magma composition and discusses the silicic magmatism in a region, where the continental lithosphere underwent significant extension. A thorough zircon geochronological study was conducted on samples collected from ignimbrites and pyroclastic fall deposits exposed in the Bükkalja Volcanic Field. In-situ LA-ICP-MS analysis on zircon grains provided a fast, cheap and accurate method for such detailed geochronological work, where the volcanic products occur in scattered outcrops that often have poor stratigraphic constraints. The interpreted eruption ages were determined from the youngest zircon age population within the samples and this methodology was validated by new single zircon CA-ID-TIMS dates and sanidine Ar-Ar ages. The volcanism covers about 4 Myrs, from 18.2 Ma to 14.4 Ma and involved at least eight eruptive phases. Within this, four large eruption events were recognized at 14.358 ± 0.015 Ma (Harsány ignimbrite), 14.880 ± 0.014 Ma (Demjén ignimbrite), 16.816 ± 0.059 Ma (Bogács unit) and 17.055 ± 0.024 Ma (Mangó ignimbrite), which are found in areas across the Pannonian Basin and elsewhere in central Europe. Considering all the potential sources of silicic ash found in the Paratethys sub-basins around the Pannonian Basin and along the northern Alps and in central Italy, we suggest that they were probably derived almost exclusively from the Pannonian Basin as shown by zircon U-Pb dates presented in this paper and published comparable age data from several localities. The new eruption ages considerably refine the Early to Mid-Miocene chronostratigraphy of the Pannonian basin, where the extensive volcanoclastic horizons are used as important marker layers. The cumulative volume of the volcanic material formed during this 4 Myr long silicic volcanism is estimated to be >4000 km3, consistent with a significant ignimbrite flare-up event. Zircon crystallization ages indicate magma intrusions and formations of magma reservoirs in the continental crust for prolonged period, likely >1 Myr prior to the onset of the silicic volcanism accompanied with sporadic andesitic to dacitic volcanic activities. Mafic magmas were formed by melting of the thinned lithospheric mantle metasomatized previously by subduction-related fluids and emplaced at the crust-mantle boundary. They evolved further by assimilation and fractional crystallization to generate silicic magmas, which ascended into the pre-warmed upper crust and formed extended magma storage regions. Zircon Hf isotope and bulk rock Sr-Nd isotopic data indicate a sharp decrease of crustal and/or increase of asthenospheric mantle input after 16.2 Ma, suggesting that by this time the crust, and the lithospheric mantle was considerably thinned. This magmatism appears to have had a structural relationship to tectonic movements characterized by strike-slip and normal faults within the Mid-Hungarian Shear Zone as well as vertical axis block rotations, when the two microplates were juxtaposed. Our new zircon ages helped to refine the age of two major block-rotation phases associated with faulting. This volcanism shows many similarities with other rift-related silicic volcanic activities such as the Taupo Volcanic Zone (New Zealand) and the Basin and Range Province (USA).

AB - The architecture of sedimentary basins reflects the relationship between accommodation space and sediment supply, their rates and localization being variable during basin evolution. The mechanisms driving the interplay between tectonics and sedimentation in extensional back-arc basins overlying rheological weak zones inherited from an earlier orogenic evolution are less understood. A typical example is the Pannonian back-arc basin of Central Europe. It is floored by continental lithosphere and was affected by large amounts of extension driven by the subduction rollback that took place in the Carpathians and/or Dinarides. A novel kinematic and seismic sequence stratigraphic interpretation calibrated by wells allows the quantification of the link between the formation of half grabens and coeval sedimentation in the Great Hungarian Plain part of the basin. While the lower order tectonic-induced cycles characterize the main phases of extension in various subbasins, the higher-order cyclicity and associated unconformities define individual moments of fault (re)activation. Our novel interpretation of a temporal and spatial migration of extension during Miocene times explains the contrasting present-day strike of various subbasins as a result of their gradual clockwise rotation. Incorporating the observed asymmetry, in particular the associated footwall exhumation, infers that the amount of extension is much larger than previously thought. The quantitative link between tectonics and sedimentation has allowed the definition of a novel model of sedimentation in asymmetric basins that can be ported to other natural scenarios of similarly hyperextended back-arc basins observed elsewhere. ©2016.

The MHZ acted as a NW vergent fold and thrust belt in the Late Oligocene. The intensity of shortening increased westwards, causing clockwise rotation of the western regions, relatively to the mildly deformed eastern areas. Blind thrusting and related folding in the MHZ continued in the Early Miocene. Thrusting and gentle folding in the MHZ partly continued in the earliest Pannonian, and was followed by sinistral movements in the whole MHZ, with maximal displacement along the Toalmas zone. Late Pannonian inversion activated thrusts and generated transpressional movements along the Toalmas zone.

Although this tectonic line was known from borehole records, it has not been described in seismic sections. The study presents interpreted seismic lines crossing the supposed trace of the Mid-Hungarian line. These seismic sections show north-dipping normal faults and thrust faults as well as cross-cutting young strike-slip faults. A complex tectonic history is deduced, including intra-Oligocene-Early Miocene thrusting, Middle Miocene extension, local Late Miocene inversion and Late Miocene-Pliocene normal faulting and left-lateral wrenching. In the light of our seismic study we think that the best candidate for the Mid-Hungarian line is a north-dipping detachment fault beneath large masses of Neogene volcanics. The auxiliary structures to the north seen on seismic sections suggest that it moved as a south-vergent thrust fault during the Palaeogene-Early Miocene which later was reactivated as a set of normal faults. The northern Alcapa unit overrode the southern Tisza-Dacia unit along this fault zone. The same relative positions are observed in the northern termination of the line. Other structures along the supposed trace of the line are north-dipping normal-or strike-slip faults which frequently were reactivated as smaller thrust faults during the late Neogene. Palaeogene-Early Miocene thrusting along the line might be the result of the opposite Tertiary rotations of the two major units, as suggested by palaeomagnetic measurements and earlier models.

Ophiolite-derived elastic components in both formations indicate a close genetic relationship with each other and with the activity of the basin-margin Darno Fault, which seems to correspond with the coeval shoreline. The Darno Conglomerate was part of a small fault-controlled fan-delta supplying coarse clastics into the sea where the Petervasara Sandstone deposited. The conglomerates occur as small lobes interbedded within a field of tidally-driven sand waves. The coarse-grained clastics, which were admired to the main material of the sandstone, have been derived from Triassic-Jurassic ophiolite-related series (Meliata nappes) east of the Darno Fault. The composition of the lobes indicates that they were formed as small spit-like platforms attached to the fan-deltas of the Darno Conglomerate. As base level rose spits became drowned and their sediment was washed into the basin and reworked by the strong northward-directed tidal currents into elongated lobes 'mimicking' sand waves. A reduction in the amount of the less resistant pebble components of ophiolite-related origin and a relative enrichment of the resistant components towards the west indicate that pebbles had partly been transported in the offshore direction. The increasing rate of accumulation of ophiolite-derived heavy minerals and pebbles along the northern part of the coast indirectly suggests a contemporaneous left-lateral displacement along the basin-margin Darno Fault.

Tide-influenced deposits prove that tidal motions in the North Hungarian Bay were locally amplified. This required a free propagation of tidal waves from the open ocean through the Paratethys into this embayment. Since all seaways towards the Mediterranean were closed during the early Eggenburgian, the only connection between the North Hungarian Bay and open marine waters, which allowed the transmission of tidal waves was the outlet towards the East Slovakian Basin in the northeast. The presence of tide-influenced deposits in the North Hungarian Bay implies that tidal waves entered the Eastern Paratethys from the east through a wide passage. Other examples of Lower Miocene tide-influenced deposits in the Mediterranean and Paratethian regions are reported from different periods. In these cases amplification of tidal motions in various embayments and straits also occurred because of the local basin morphology. It is demonstrated that significant palaeogeographic changes during the Early Miocene resulted in changes of current pathways and related shifts of loci of tide-influenced deposition.

The early Miocene basin evolution is best understood in terms of ''molasse'' sedimentation in an overfilled flexural basin. During this time the gradual cessation of thrusting in the adjacent West Carpathian thrust-fold belt resulted in its uplift and subaerial exposure. Significant amounts of sediment were delivered to the flexural basin filling it up to sea level. During the late-stage uplift of the flexural basin a shallow-marine depositional environment developed, as a result of isostatic rebound, and signals of third-order eustatic sea-level changes can be revealed. Sedimentological studies of outcrops of the Lower Miocene succession proved marked changes in facies. Along the gently dipping distal (southeastern) flank of the basin a sudden inception of shallow-marine coarse clastics on top of siltstones, deposited in significantly deeper water, may have been the result of a third-order eustatic sea-level fall shortly before the Burdigalian (at the boundary of the NN1/NN2 nannofossil zones). During the resulting lowstand, various tide-dominated facies aggraded, which were subsequently flooded by the ''Burdigalian sea-level rise''. The highstand is represented by upwards shallowing progradational units due to accelerating sedimentation and/or tectonic uplift. The typically elongated and narrow flexural basin, characterized by small water depth, had dimensions which were particularly suitable for the amplification of tidal motions. This resulted in the deposition of tide-influenced sandy sediments. In contrast to examples where the evolution of a strong tidal influence is related to transgressions, here such conditions developed following a drop of sea level.
