Abstract (in english)
   The Moravosilesian area is unique case due to superposition of three structural levels, corresponding to three orogeny cycles. Lower most Pan-African (Cadomian) Brunovistulicum foreland terrane conditioned and influenced complex geological and among other deformation development of later Variscan accretion wedge. Finally sequences of the West Carpathian foredeep and the Outer West Carpathian nappes formed Alpine accretion wedge. The morphotectonic analysis is based on 3D visualization and interpretation of digital elevation models (DEM) of above-mentioned structural levels (Pan-African, Variscan and Alpine). Sedimentary loading caused by West Carpathian Molasses sedimentary filling, alike as tectonic loading by Other Carpathian nappes, significantly conditioned and influenced development of lithospheric flexure of Alpine foreland and mainly its brittle faults activation - rifting and volcanic activity.
   Distinct block tilting is typical brittle deformation of rigid Brunovistulian basement that followed genesis of asymmetric lithospheric flexure. The Alpine rejuvenation is indicated equally on originally Variscan originated faults
