V originále

The Blansko trough is the southernmost relic of the Bohemian Cretaceous Basin. The Cretaceous sediments of the trough cover the Cadomian Brno Massif. The tectonic contact between the trough and the massif was the main aim of this contribution. Uncovering of disappearing locality was made on the southwest edge of the sandstone quarry in Dolní Lhota. The fault core is represented by several decimeters thick zone of tectonic clay (219/53). Subsequently ten samples were taken from the fault core to determine direction of tectonic movement by anisotropy of magnetic susceptibility. Resulted AMS-data from samples taken in the locality were plot by Anisoft in azimuthal equal-area Lambert projections on the lower hemisphere (Fig. 1). The longest axes K1 are equal to magnetic lineation. The average orientation of K1 is horizontal in the SW-NE direction (260/0). The shortest axes K3represent poles of magnetic foliation. The average direction of K3 dips under steep angle to the NNW–N (351/59). The middle axes K2 have average orientation of 171/36. The results from the AMS appear to be different in comparison to the values expected from the regional situation. The variance of the results should be explained by the younger deformation along supposed transverse fault comparable to faults observed by Havíř (1998).
