Sažetak
The research was carried out along the profile GP-3 crossing the central Dinarides, and extending from the Adriatic Sea towards Split and Banja Luka to the Hungary.Five permanent seismic stations and two temporary seismic stations from ALPASS-DIPS project are located on the profile. The teleseismic data were interpreted by receiver functions method (RF). The receiver functions analysis enabled more precise definition of geological model along the profile GP-3. The RF is mainly used to map the velocity discontinuities. Moho layer can be usually very easy identified, but also discontinuities in the crust and sedimentary basement. The results correlate well with density model obtained by gravity modelling. The general geological model along GP-3 profile was constructed, that correlate well with geological model on the profile Alp07 (Šumanovac et al., 2016), which is based on all three datasets: gravity, seismic refraction and receiver functions. Along both profiles, GP-3 and Alp07, RF show thickening of the crust under the Dinarides (40-50 km) and significant thinning under the Pannonian basin (20-25 km). However, depths of the Moho under the Dinarides and suture zone obtained from RF are greater than the depths based on the refraction and gravity data.
