ORIENTATIONS OF PALEOSTRESSES IN THE JURASSIC LIMESTONES ON THE FRONT OF THE WEST CARPATHIAN FLYSCH NAPPES (PAVLOV HILLS, SOUTH MORAVIA)

Year, pages: 2003, 409 - 416

The paleostress analysis was applied at 16 sites in the Mesozoic limestones, which are tectonically incorporated into the Cretaceous and the Paleogene strata on the front of the West Carpathian flysch nappes (South Moravia, Czech Republic). 25 solutions were obtained. These solutions can be divided into two groups. The first group represents the paleostress field with predominantly NW-SE compression and NE-SW extension connected with the Early Neogene movements of the Zdanice Nappe. The azimuth of eigenvector of acceptable σ₁ axes varies from 97° up to 167°. This variability can be explained by rotation of individual tectonic slices of the Zdanice Nappe during the movement of this nappe. The different tectonic scales probably rotated in different directions (anticlockwise rotation in the case of some scales, clockwise rotation in the case of others). The second group of solutions represents the paleostress field with NE-SW compression and NW-SE extension.
