1. Quantitative analysis of deformation structures and their numerical modelling 10Figure 1.4: Geometry of main tectonic units of Central Western Carpathiansand schematic evolution of major structures during progressive deformation used toparametrize subsequent numerical model.Figure 1.5: Finite strain pattern developed in Gemer unit after 5 Myr of shortening.(a) Distribution of strain intensity (D) and orientation of finite strain ellipsoid.

1. Quantitative analysis of deformation structures and their numerical modelling 11Figure 1.6: Stereographic projection showing influence of inter-limb angle and anglebetween fold axial plane and main anisotropy. The range of section planes showingshear-band geometry increases with inter-limb angle of folds affecting main anisotropy.Vissers, 1989). Some field observations, however, were cautionary: Are geologists alwayssure about mutual orientation of observed plane and kinematic frame? Are all the“extensional shear bands” really extensional structures? I tried to answer these questionsin a simple fold section model (Lexa et al., 2004) which showed that from all thepossible sections of 3D fold structure, only a small percentage allows us to observe theactual fold shape. In fact, in most of the sections, asymmetric fold structure appears as“extensional shear bands”. Our own observation from the central Western Carpathiansand from eastern margin of Bohemian Massif revealed that most of “extensional shearbands” represent only the oblique sections across compressive folds (Fig. 1.6).This important observation seriously modifies the today view on origin or core complexes,which can be only the oblique sections across the crustal scale folds. For instance,the discussion of origin of Montagne Noire gneiss dome as a core complex or steep crustalmegafold is debated for more than twenty years by French geologists (e.g. Aerden, 1998,Matte et al., 1998, Van den Driessche and Brun, 1992). We believe that the analysisof kinematics of such orogenic systems requires a thorough revision in the light of theseobservations. Similar conclusion could be made about the origin of Tauren Window as itis shown by contrasting interpretations (e.g. Ratschbacher et al., 1989, Rosenberg et al.,November, 2004).
