“…EuCRUST-07 is largely compiled from the results of seismic refraction, reflection and receiver function studies, most of them carried out within recent international projects, such as CELEBRATION2000 ), SUDETES 2003), ALP 2002(Brück et al, 2003), ESCI-N (Fernández-Viejo, 2005, CROP (Finetti, 2005a). Available local models based on seismic data (e.g., SVEKALAPKO, Kozlovskaja et al, 2004) were also incorporated.…”

The book series is dedicated to the United Nations International Year of Planet Earth. The aim of the Year is to raise worldwide public and political awareness of the vast (but often under-used) potential of Earth sciences for improving the quality of life and safeguarding the planet. Geoscientific knowledge can save lives and protect property if threatened by natural disasters. Such knowledge is also needed to sustainably satisfy the growing need for Earth's resources by more people. Earths scientists are ready to contribute to a safer, healthier and more prosperous society. IYPE aims to develop a new generation of such experts to find new resources and to develop land more sustainably.

“…However, because of its location in a tectonically interesting zone at the transition of the Eastern Alps to the Pannonian basin it yielded valuable data about the Moho structure. Recent wide-angle reflection and refraction (WAR/R) experiments [Guterch et al, 2003 and ALP 2002 [Brückl et al, 2003] covered large portions of our study area (Figure 1). Several profiles (Alp01, Alp02, CEL10/Alp04, Alp07) from these experiments were evaluated by 2-D ray trace modeling and provide important new information about crust and upper mantle Grad et al, 2009;Šumanovac et al, 2009].…”

[1] During the last decade, a series of controlled source seismic experiments brought new insight into the crustal and lithospheric structure of the Eastern Alps and their adjacent tectonic provinces. A fragmentation of the lithosphere into three blocks, Europe (EU), Adria (AD), and the new Pannonian fragment (PA), was interpreted and a triple junction was inferred. The goal of this study has been to relate these deep crustal structures to active tectonics. We used elastic plate modeling to reconsider the Moho fragmentation. We interpret subduction of EU below AD and PA from north to south and underthusting of AD mantle below PA from southwest to northeast. The Moho fragmentation correlates well with major upper crustal structures and is supported by gravity, seismic, and geodetic data. An analysis of crustal thickening suggests that active convergence is associated with continued thrusting and lateral extrusion in the central Eastern Alps and thickening of the Adriatic indenter under the Southern Alps. According to the velocity relations at the triple junction, PA moves relative to EU and AD along ENE and SE striking faults, mainly by strike slip. An eastward directed extensional component is compensated by the lateral extrusion of the central Eastern Alps. The Periadriatic (Insubric) line east of the triple junction and the mid-Hungarian fault zone have relatively recently lost their role as first-order active structures. We favor the idea that the Pannonian fragment and the TISZA block merged to a "soft" microplate surrounded by the Eastern and Southern Alpine, Carpathian, and Dinaric orogens. Citation: Brückl, E.,

“…As follows, the region is a complex of tectonic units ranging from Cadomian to Tertiary age with Variscan to Alpine tectonics. In an effort to investigate such a structure, central Europe has been covered by a network of seismic refraction experiments (POLONAISE'97, CELEBRATION 2000, ALP 2002 as a result of a massive international cooperative effort (Guterch et al 1998(Guterch et al , 1999(Guterch et al , 2003aBrückl et al 2003;Grad et al 2003a,b). This paper focuses on the refraction and wideangle reflection experiment SUDETES 2003, which involved a consortium of European and North American institutions comprising geophysical groups from the Czech Republic, Poland, the United States, Germany, Slovakia and Hungary.…”

S U M M A R YThe Variscan orogeny is the major Middle to Late Palaeozoic tectonometamorphic event in central Europe, and the Bohemian Massif is the largest exposure of rocks deformed during this orogeny. The Bohemian Massif consists of the Saxothuringian, Barrandian and Moldanubian units. Adjacent to this massif in the southeast, the Western Carpathians form an arc-shaped mountain range related to the Alpine orogeny during the Cretaceous to Tertiary. The complex crustal-scale geological structure of the Variscan Bohemian Massif and the Western Carpathians, and especially their contact, were analysed in this study employing the data of the SUDETES 2003 international seismic refraction experiment. The analysed seismic data were acquired along the 740 km long, NW-SE oriented S04 profile that crossed the Bohemian Massif and the Western Carpathians before terminating in the Pannonian Basin. The data were interpreted by 2-D trial-and-error forward modelling of P waves, and additional constraints on crustal structure were provided by gravity modelling.The complex velocity structure derived in our analysis included low velocities of 5.85 km s −1 at the contact of the Saxothuringian and Barrandian units that reflect the presence of lowdensity granites. There are distinct lateral variations in deep crustal structure in the transition between the Bohemian Massif and the Western Carpathians. The abrupt change of the crustal thickness in this transition zone may be associated with the Pieniny Klippen Belt, a deep-seated boundary between the colliding Palaeozoic lithospheric plate to the north and the ALCAPA microplate to the south. In the upper crust of this transition, low velocities of 4 km s −1 extend to 6 km and represent the sedimentary fill of the Carpathian Flysch and Foredeep that thins towards the foreland. This basin is also expressed as a pronounced gravity low. The Moho in the Carpathians reaches a depth of 32-33 km. In contrast, in the Pannonian Basin the Moho rises to a depth of 25 km, which corresponds to the Pannonian gravity high.
