Seismic image of the crust on the PANCAKE profile across the Ukrainian Carpathians from the migration method

The migrated seismic image of the upper crystalline crust, Moho interface and uppermost mantle have shown that the crust of the ALCAPA microplate was significantly reworked by young (Neogene) tectonic and thermal processes related to formation of Pannonian back-arc basin. The Moho here is associated with a quite thick (∼10 km) package of high reflectivity and seismic heterogeneity at the depth range 25-35 km. In the subcrustal mantle there are distinguished oblique seismic boundaries gently dipping to the east/northeast below the EEC and related to recent collision processes at the southern margin of the EEC.
