Sažetak
Two-dimensional interpretation of the ALP07 profile, as a part of the ALP 2002 Project was carried out in order to define the contact between the Dinarides and the Pannonian segment. The profile ALP07 stretches in Croatia in the WSW– NNE direction from Istra to the Drava river at Hungarian-Croatian border. Four layer model was established based on a tomographic inversion by using the Hole method. This model was used as initial model for forward seismic modelling by the Ray Tracing method and final seismic model was defined. A two-dimensional gravity modelling along the profile was also performed due to reducing the ambiguity of geophysical interpretation. Geological model was constructed based on both models, seismic and gravimetric. Two types of crust are defined, the Dinaridic and the Pannonian crusts, between which there is a relatively wide Transition zone. Troughs in seismic model at the level of Mohorovičić discontinuity are interpreted as major breaks in the lithosphere. The Dinaridic crust is divided into two parts: upper and lower crust. Upper crust is characterised by low seismic velocities and densities, but lower crust by high velocities and densities. The Pannonian crust can be seen as unique layer characterised by low seismic velocities and densities.
