Morphostructural manifestation of the joint zones of main morphotectonic regions in Bulgaria

Abstract

Evolution of main morphostructural region of Bulgaria and Balkan peninsular is considered on the basis of Plate-tectonic conception. There were four stages of alpine orogenic activity with intensive lateral movements. The significance of vertical and subvertical movements enlarged in the neotectonic epoch only. Liminar (contact) morphostructural lineaments are characterized by tectonic deformations of high amplitudes; they have certain similarity as well as important morphological discrepancies.
