Description In the locality Hevlín, deformation zone with a dense network of small faults was recognized in Neogene clay of the Carpathian Foredeep. Faults are striking in N–S to NW–SE direction and dipping from E to NE. Two systems of striae were found on fault surfaces. The older one is plunging under medium-sized angles, while the younger is almost sub-horizontal. Corresponding older stress phase has orientation sigma1 273°/69°, sigma2 98°/21° and sigma3 7°/2° (mu = –0.61), and younger sigma1 333°/43°, sigma2 70°/7° and sigma3 167°/46° (mu = –0.31). These orientations do not match Anderson‘s theory of fracturing and could be perhaps explained by permeating of movements on some fault in the bedrock.
