“…this map was calculated by taking into account the present-day depth to the pre-Neogene basement and the heat flow, assuming an initial crustal thickness of 35 km. Lenkey (1999) derived the depth to the pre-Neogene basement from the isopach map of the Neogene sediments in the Pannonian basin that was published by Horváth and royden (1981). We also implemented the fault pattern in the Pannonian basin as given by Horváth (1993) and Horváth et al (2006).…”

“…We subdivided these transects at their intersection points with normal faults into several segments i, which are characterised by variable crustal thinning factors. For each transect segment we estimated the magnitude of extension as follows: (1) where l 0 is the initial length of a segment prior to extension, l 1 its present-day length after extension and δ the crustal thinning factor as given by Lenkey (1999). Once l 0 was obtained for each transect segment, the magnitude of extension dl (length change) along each segment could be estimated:…”

“…Estimates on the magnitude and direction of extension in the eastern (Pannonian basin) part of ALcAPA were mainly adopted from tari (1996), and also from Fodor et al (1998) andszafián et al (1999). In addition, we used the crustal thinning factor map for the Pannonian basin by Lenkey (1999) to estimate the magnitude of extension affecting the ALcAPA and tisza parts of the Pannonian basin. For the West carpathians, we took the restorations by roure et al (1993), roca et al (1995), Morley (1996) and behrmann et al (2000) into consideration for estimating the total shortening that was achieved in the Miocene external thrust belt.…”

A map-view palinspastic restoration of tectonic units in the Alps, carpathians and Dinarides reveals the plate tectonic configuration before the onset of Miocene to recent deformations. Estimates of shortening and extension from the entire orogenic system allow for a semi-quantitative restoration of translations and rotations of tectonic units during the last 20 Ma. Our restoration yielded the following results: (1) the balaton Fault and its eastern extension along the northern margin of the Mid-Hungarian Fault Zone align with the Periadriatic Fault, a geometry that allows for the eastward lateral extrusion of the Alpine-carpathian-Pannonian (ALcAPA) Mega-Unit. the Mid-Hungarian Fault Zone accommodated simultaneous strike-perpendicular shortening and strike-slip movements, concomitant with strike-parallel extension. (2) the Mid-Hungarian Fault Zone is also the locus of a former plate boundary transforming opposed subduction polarities between Alps (including Western carpathians) and Dinarides. (3) the ALcAPA Mega-Unit was affected by 290 km extension and fits into an area W of present-day budapest in its restored position, while the tisza-Dacia Mega-Unit was affected by up to 180 km extension during its emplacement into the carpathian embayment. the displacement of the Adriatic Plate indenter led to a change in subduction polarity along a transect through the easternmost Alps and to substantial Neogene shortening in the eastern southern Alps and external Dinarides. While we confirm that slab-pull and rollback of oceanic lithosphere subducted beneath the carpathians triggered back-arc extension in the Pannonian basin and much of the concomitant folding and thrusting in the carpathians, we propose that the rotational displacement of this indenter provided a second important driving force for the severe Neogene modifications of the Alpinecarpathian-Dinaridic orogenic system.

“…The data can be altered during each modelling step so the modelled temperature and vitrinite re ectance (VR) correspond to the actual ones in the wells. Heat ow was set at a 70 mW/m as shown in [20]. SWIT was determined from regional values from [21] and PWD was set according to the reconstructions in [5] in the range from 0 m (recent) to 50 m regarding environments that existed for deposition of members of the Lonja Formation.…”

Modelling of maturation, expulsion and accumulation of bacterial methane within Ravneš Member (Pliocene age), Croatia onshore

Bacterial methane is a dominant hydrocarbon component in the Northern Croatia's Adriatic o shore proven hydrocarbon reservoirs. As onshore reserves are declining the potential of shallow gas accumulation, analogue to the Adriatic ones, are being tested. A part of the Lonja Formation (Pliocene Pleistocene and Holocene), the Ravneš Member (Early Pliocene age) is analysed for its maturation and expulsion regarding bacterial methane as potential source and reservoir rocks, especially as it is thermally immature. Two approaches were used for the initial lithology modelling processes -the convergent interpolation and sequential Gaussian simulation. Possibility for trapping and forming of accumulations was also modelled. Results show that selected member has a large source rock potential for bacterial methane with a total volume of . × m for the Convergent interpolation model and . × m for the sequential Gaussian simulation model of expulsed bacterial methane.

Neotectonics and long‐term seismicity in Europe and the Mediterranean region

We present a neotectonic model of ongoing lithosphere deformation and a corresponding estimate of long-term shallow seismicity across the Africa-Eurasia plate boundary, including the eastern Atlantic, Mediterranean region, and continental Europe. GPS and stress data are absent or inadequate for the part of the study area covered by water. Thus, we opt for a dynamic model based on the stress equilibrium equation; this approach allows us to estimate the long-term behavior of the lithosphere (given certain assumptions about its structure and physics) for both land and sea areas. We first update the existing plate model by adding five quasirigid plates (the Ionian Sea, Adria, Northern Greece, Central Greece, and Marmara) to constrain the deformation pattern of the study area. We use the most recent data sets to estimate the lithospheric structure. The models are evaluated in comparison with updated data sets of geodetic velocities and the most compressive horizontal principal stress azimuths. We find that the side and basal strengths drive the present-day motion of the Adria and Aegean Sea plates, whereas lithostatic pressure plays a key role in driving Anatolia. These findings provide new insights into the neotectonics of the greater Mediterranean region. Finally, the preferred model is used to estimate long-term shallow seismicity, which we retrospectively test against historical seismicity. As an alternative to reliance on incomplete geologic data or historical seismic catalogs, these neotectonic models help to forecast long-term seismicity, although requiring additional tuning before seismicity rates are used for seismic hazard purposes.
