The Scythian Platform (ScP) with a heterogeneous basement of Baikalian–Variscan–Cimmerian age is located between the East European Craton (EEC) on north and Crimean–Caucasus orogenic belt Black Sea (BS) Basin south. In order to get new constrains basin architecture crustal structure ScP better understanding tectonic processes evolution southern margin EEC during Mesozoic Cenozoic time, 630-km-long seismic wide-angle refraction reflection (WARR) profile DOBRE-5 was acquired in 2011 October....

In order to study the lithospheric structure in southern Ukraine, a seismic wide-angle reflection/refraction project DOBRE-4 was conducted. The 500-km-long profile starts SW from Alpine/Variscan North Dobrudja Fold-Thrust Belt, being part of Trans-European Suture Zone. It runs NE, mostly along NW Black Sea coastal plain, towards centre Precambrian Ukrainian Shield. field acquisition October 2009 included 13 chemical shot points with charge sizes 600–1000 kg every 35–50 km and 230 recording...

The GEORIFT 2013 (GR'13) WARR (wide-angle reflection and refraction) experiment was carried out in the territory of Belarus Ukraine with broad international co-operation. aim work is to study basin architecture deep structure Pripyat–Dnieper–Donets Basin (PDDB), which deepest best studied Palaeozoic rift Europe. PDDB located southern part East European Craton (EEC) crosses Sarmatia—one three segments EEC. formed by Late Devonian rifting associated domal basement uplift magmatism. GR'13...

Magnetic, gravity, geothermal, seismic and tomographic data from the lithosphere were first jointly examined. A multidisciplinary interpretation has resulted in a new consistent model for lithospheric density, magnetic, thermal velocity heterogeneities. Faults of different orders crystalline crust have been mapped details. Large deep fault zones recognized. Among them is most prominent Odessa-Sinop-Ordu (OSO) zone, which played key role opening development Black Sea Depression. fundamental...

We present a new digital Moho depth map of the Carpathian-Pannonian region. The was produced by compiling discontinuity data, which were obtained interpretation seismic measurements taking into account results 2-D and 3-D integrated geophysical modelling. resultant is characterized significant Moho-depth variations. trends features in this region correlated with tectonic units.

Abstract The DOBRE-2 wide-angle reflection and refraction profile was acquired in June 2007 as a direct, southwestwards prolongation of the 1999 DOBREfraction'99 that crossed Donbas Foldbelt eastern Ukraine. It crosses Azov Massif East European Craton, Sea, Kerch Peninsula (the easternmost part Crimea) northern Black Sea Basin, thus traversing entire Crimea–Caucasus compressional zone centred on Peninsula. recorded mix onshore explosive sources well airguns at sea.

The TTZ-South seismic profile follows the Teisseyre-Tornquist zone (TTZ) at SW margin of East European craton (EEC). Investigation results reveal upper lithospheric structure as representing NW-vergent, NE-SW striking overthrust-type, Paleoproterozoic (~1.84–1.8 Ga) Fennoscandia-Sarmatia suture. Sarmatian segment EEC comprises two crustal-scale tectonic thrust slices: Moldavo-Podolian and Lublino-Volhynian basement units, overriding northerly located Lysogoro-Radomian unit Fennoscandian...

Three-dimensional Earth’s crust density model of the central part Golovanevsk suture zone Ukrainian Shield at scale 1:50 000 has been given. Model calculations were carried out using automated complex GMT-Auto. The takes into account change in both laterally accordance with petrophysical data; and depth seismometry data. In this case; an abrupt one direction or another; inversion constant was taken consideration. rated bodies on surface basement defined based percentage ratio constituent...
