Crustal structure of the Dinarides and edge part of the Pannonian Basin based on two-dimensional interpretation of the ALP07 profile

The 300 km long seismic profile Alp07 extends in Croatia in the WSW– ENE direction from Istra to the Drava river at Hungarian-Croatian border. It is approximately perpendicular to the Dinarides and the main faults in the Adriatic region, including a contact between the Dinarides and Pannonian basin. Two-dimensional seismic modelling was done using tomographic inversion and ray tracing technique. In order to obtain more reliable data on the crustal composition, the 2-D gravity modelling was also performed. A geological model was constructed based on both geophysical models. Three types of the crust were found along profile: the Dinaridic and the Pannonian crusts that are separated by a relatively wide transition zone.
