Within the Hungarian segment of the Pannonian basin, a 100-km-long seismic reflection profile images the sedimentary fill of two major depressions and their associated crustal signatures. These deep (∼7000 m) subbasins are asymmetric half grabens, bounded along their western margins by low-angle crust-penetrating subparallel listric faults. The hanging walls are intensely fractured and comprise pre-Tertiary basement and upper-crustal rocks. The footwalls are formed by uplifted and ductilely deformed middle to lower crust. The crust is relatively thin (25-27 km) and decoupled by well-defined detachment faults. The Moho has a gentle northeasterly dip and a spatially variable seismic signature. The seismic images imply that the present crustal setting of the area was developed contemporaneously through the northeastward extension of the Pannonian basin.
