Exploring the lithospheric structure beneath the Dinarides using seismograms of teleseismic earthquakes
The Dinarides are a mountain range located in southeastern Europe with significant tectonic activity and complicated geologic history shaped by the collision of the Adriatic microplate and the European mainland. There are numerous open questions about the current state of interaction between Adria and Eurasia under the Dinaric domain. One of the most interesting is the nature of lithospheric underthrusting of the Adriatic plate, e.g. length of the slab or varying slab disposition along the orogen. In this talk, I will describe two recent studies made to investigate the Dinaric upper mantle structure. In the first study we used S receiver functions to obtain the lithospheric thickness, while in the second one, we used the dispersion of Rayleigh waves to create a 3D shear wave velocity model. I will discuss the results of them in the context of regional tectonics.
