We investigated exhumed damage zones of dextral strike-slip faults dissecting the south-western part Mesozoic cover Late Palaeozoic Holy Cross Mountains Fold Belt. Structural observations allow to examine top 1–2 km fault that deformed asymmetrically with most intense controlled by non-planar geometry faults. The deformational style and roughness slip surfaces on subsidiary within deflections traces in restraining releasing bends were facilitated rock fabric porosity. High porous sandstones enhanced genesis cataclastic shear bands zone smooth surfaces. Low limestones formation dilatant structures infilled calcite rough complex structural pattern records multiple episodes shows evidence continuous seismic–aseismic modes behaviour.
