Abstract

Summary

The Carpathian-Pannonian region is traditionally interpreted as accretionary prism - back-arc basin system, although alternative models exist. This study presents balanced geological cross-section, crust tectonic model on base of seismic images obtained by migration method combined of the depth of asthenosphere along PANCAKE profile to understand geodynamics of study region. The geological cross-section shows thrust tectonics with significant horizontal NE displacements. A basal detachment of Carpathian allochthon locates at 12–15 km depths. Tectonic model by migration method shows pre-Alpine Carpathian basement at ~ 15 km in agreement with geological and balanced cross-sections. New seismic boundary within uppermost mantle dipping at low angle under the East European Craton (EEC) was obtained. It is associated with collision and thrusting of marginal part of ALCAPA lithosphere under EEC. The surface dipping in opposite direction could be associated with SW subdu ction was not found. The geometry of asthenosphere and gravity field allows localizing TESZ. Within TESZ maximum thickness of lithosphere beneath the Carpathians is observed, indicating a significant role of this lithospheric boundary in development of SW-margin of EEC and Ukrainian Carpathians. Lithosphere thinning under Pannonian Basin larger than crust thinning emphasizes the main role of mantle upwelling in evolution of Carpathian-Pannonian region.
