There is a problem of the mechanism of Neogene magmatism appearance in Transcarpathia within tectonic evolution of the Carpathian-Pannonian region. In consideration of general submeridional compression the new kinematic and dynamic scheme of Neogene tectonic and magmatic activation associates magmatism with formation of the shear-zone with right-shift structural paragenesis in the Transcarpathian trough area. According to the scheme the sources

The intensive tectonophysical research in the Transcarpathia began in the 50s of the twentieth century and used kinematical as well as structural and paragenetic analysis in combination. Plenty of sublatitudinal and submeridional tectonic dislocations in the Transcarpathian trough were found during the research. The preliminary structure-paragenic analysis of the Transcarpathian faults grid as well as magmatic center distribution data permit to suggest the new dynamo-kinematical scheme of Neogene volcanism in Ukrainian Carpathians. According to this scheme the general submeridional compression process of Carpathian fold system caused the right-side split zone in Transcarpathia. The split zone is restricted on the north by Transcarpathian deep fault that has northwestern strike and subvertical decline. The southern boundary is not so clear. It includes the territory between Samozh (Somezh) fault and Pannonian deep fault, where dislocation movements were complicated, probably, by shifting of the tectonic blocks. The split zone and magmatic active structures of dilatation form the flaw structural paragenesis, which is complicated by faults of higher degree (synthetic R-splits and antithetic R’-splits). On some geological maps faults with ancillary P-splits can be found. Intensification of noncoaxial movement in the split zone activates the turning of break structures (which causes their extension) and Riedel splits. The suggested geodynamic control scheme of Neogene volcanism in Transcarpathia is perspective both in theoretical and research prospects with further substantiation of this scheme.
