One common phenomenon appears in the magnetotelluric models across the Western Carpathian Alpine, Bohemian Hercynian and Scandinavian Caledonian orogenic zones – significant deep subvertical orogen parallel conductive zones in the crust. On the basis of knowledge from the Western Carpathians, we interpret them as shear zones that were formed after the end of oceanic subduction and the subsequent collision between the continental blocks by the transition of the collisional tectonics to transpression. The deep shear zone allowed mineralized fluids and CO₂, which formed a significant conductivity anomaly, to escape from the mantle. The occurrence of such large-scale orogen parallel shear zones in the investigated orogens points to the similarity of the kinematic regime in the orogens from different ages, at least in the Phanerozoic.
