“…These inclined seismic boundaries at 60-70 km depth were associated with collisional interactions (including underthrusting) of younger lithospheric terranes (ALCAPA and Tisza-Dacia) with the Caledonian-EEC lithosphere beyond the Carpathian arc (e.g. Grad et al, 2006b;Guterch et al, 2015;Verpakhovska et al, 2018).…”

“…The deep structure of the TTZ where it is obscured by the Eastern Carpathians is crossed by WARR profiles PANCAKE (Starostenko et al, 2013;Verpakhovska et al, 2018), from Ukraine into the Pannonian Basin in Hungary, and VRANCEA99 (Hauser et al, 2001) and VRANCEA-2001(Hauser et al, 2007, which intersect in the foreland of the Carpathian belt at its southeasternmost tip, the former running SSW-NNE, subparallel to RomUkrSeis and the latter perpendicular to it, crossing the TTZ at a fairly oblique angle. VRANCEA-2001 is also, in part, imaged by deep reflection seismic profiling ( -Panea et al, 2005).…”

“…The emplacement of the Carpathian sedimentary prism in the upper crust is not very sensitive to the choice of a subduction or delamination model; in either case upper crustal, mainly sedimentary units but also incorporating some crystalline basement rocks (e.g. Roure et al, 1993;Bocin et al, 2005;Verpakhovska et al, 2018), have been folded and stacked and this represents a concomitant shortening of upper crustal lithosphere. According to Burchfiel (1976) there is some 125 km of shortening recorded in the eastern Carpathian fold-and thrustbelt from the palinspastic restoration of a geological cross-section about km south of the RomUkrSeis profile.…”

RomUkrSeis: Seismic model of the crust and upper mantle across the Eastern Carpathians – From the Apuseni Mountains to the Ukrainian Shield

RomUkrSeis is a controlled source wide-angle reflection and refraction (WARR) profile acquired in August 2014. It is 675 km long, running roughly SW-NE from the Apuseni Mountains in Romania and the Transylvanian Basin, crossing the arc of the Eastern Carpathian orogen and terminating in the East European Craton (EEC) in SW Ukraine. Wellconstrained 2-D ray-tracing P-and partly S-wave velocity models have been constructed along the profile from 348 single-component seismic recorders and eleven shot points. The Eastern Carpathian arc formed in the Cenozoic and have obscured the pre-existing Teisseyre-Tornquist Zone (TTZ), which is a transition zone between the Precambrian EEC and continental terranes accreted to it from the southwest in the Palaeozoic. The TTZ is characterised by low-velocity through its entire crust (6.0-6.3 km/s) and a considerable width (~140 km). It is interpreted as EEC crust stretched during rifting and continental margin formation in the Neoproterozoic and early Palaeozoic. The crust of the TTZ has a structure wherein an upper body of ~40 km width comprising Outer Carpathian (V p 4.9 km/s) and Late Palaeozoic-Mesozoic (V p 5.4 km/s) units to 15 km depth lies above a wider, deeper one of inferred Neoproterozoic-early Palaeozoic strata. The crust of the Transylvanian Basin and Apuseni Mountains is relatively thin (~32 km). A high-velocity body at 4-12 km depth in this area is interpreted as a rootless fragment of an ophiolite complex exposed at the surface in this area. The lower crust beneath the Transylvanian Basin displays higher velocities than adjacent segments. Moho topography is strongly differentiated along the profile, varying from 32 to 50 km. The Moho shape, especially in the area between the Inner and Outer Carpathians, suggests a NE dip and, hence, thrusting of the Tisza-Dacia lowermost crustal and upper mantle units under the TTZ domain which, in turn, could be thrust under the cratonic (EEC) block.

Scientific review of the latest author’s works on tectonics and geodynamics of the territory of Ukraine, as well as its connection with the localization of mineral deposits, is presented. The structure and evolution of lithosphere of the Carpathian and Black Sea segments of Ukraine, the Dnieper-Donetsk Basin, Donbass Foldbelt and Ukrainian Shield has been reconstructed based on the interpretation of regional deep sounding (DSS) and reflection (CDP) seismic profiles, the geomagnetic field data, geological-structural mapping, paleotectonic, numerical modeling, paleogeographical and palinspastic reconstructions. When interpreting the DSS profiles, the classic velocity models are supplemented with seismic images obtained by the original finite-difference reflection/refraction migration method. The monograph included scientific study carried out at the S.I. Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine with the involvement of seismic and related geophysical data obtained as a result of conducting and interpreting regional wide-angle seismic profiles (WARR): DOBRE’99, PANCAKE and RomUkrSeis. Geological interpretation of reflection seismic profiles of the Ukrainian sector of the Black Sea, paleogeographical and palinspastic reconstructions contributed to the study of the evolution of the entire Black Sea region. The geological evolution of the Ukrainian Carpathians is reconstructed on the basis of updated data on stratigraphy, tectonics, lithology and sedimentology and palinspastic reconstructions. The structure and development of the DDB sedimentary cover was revealed by seismogeological sections along numerous reflection (CDP) seismic profiles. The tectonics of the Precambrian Ukrainian Shield, including the Kryvyi Rih-Kremenchug and Golovanivsk suture zones, were studed by geomagnetic field analysis and detailed geological and structural mapping.
