Abstract (in english)
   There is a special occurrence of Upper Devonian rocks within the Proterozoic granodiorites of the Brno Massif in the surroundings of Adamov (about 1 km NNE of Adamov). The outcrops consists of basal clastics and limestones. The rocks are strongly ductile or brittle-ductile strained. The dip direction and dip of foliation vary from 316/88 in the basal clastics to 256/50 in the limestones. The trend and plunge of axis of the cylindricity is 220/38 and corresponds to the average lineation 215/29. The setting of the Devonian rocks in Proterozoic granodiorites is interpreted as a tectonic slice along a fault plane. According to asymmetric structures, the western block was thrusted over the eastern block to the NE. The deformation passed through several steps: 1. Upper block was thrusted over the loer one (D1); 2. This tectonic zone was strained by younger dextral thrust (D2); 3. The final structure was modified by neotectonics faulting and rotation
