Транскурентное разломление и сегментированное строение Фрако-Мизийской коллизионной зоны на Балканах

Ekim Bončev. Transcurrent faulting and segmented structure of the Thracian-Moesian collision zone. The author develops further his ideas about the geodynamic role of the two lithospheric plates in Southeast Europe, the Moesian and the Thracian ones, as related to the evolution of the collision zone between them. During the Vendian-Cambrian the latter was a spreading zone in the Triballian microocean. During the Phanerozoic it provided the ground for the superposed development of the northern branch of the Alpine orogen, the Balkanids. The evolution of the zone is marked by multiple alternation of divergent and convergent tectonics. The Thracian-Moesian collision zone was synkinematically segmented by equidistant transcurrent faults. The separate segments show specific geological structure. During the Phanerozoic they suffered horizontal and less pronounced vertical displacements, and rotations. Their boundaries are low structural zones of prolonged development.
