Abstract
Structural interpretation of reflection seismic profiles reveals distinct modes of upper crustal extension in the Pannonian Basin. While some subbasins in the Pannonian Basin complex show little extension (planar rotational normal faults), others are characterized by large magnitude of extension (detachment faults, metamorphic core complexes). Gravitational collapse of the Intra-Carpathian domain, combined with subduction zone roll-back is thought to be the driving mechanism of the Neogene back-arc extension. The very heterogeneously distributed extension is accommodated by transfer faults, which bound regions characterized by different polarity, direction, or amount of extension. In cross section these transfer faults are characterized by flower structures, typical for strike-slip faults. Seismic stratigraphic interpretations indicate that the non-marine post-rift sedimentary fill of the Pannonian Basin can be described in terms of sequence stratigraphy. The exceptionally good seismic sequence resolution allows recognition of third-order and also fourth-order depositional sequences, which may reflect the interplay of tectonics and eustasy, and Milankovitch scale climatic variations, respectively.
