| Description | The Prague Synform (Teplá-Barrandian region, Bohemian Massif) represents remains of Ordovician to middle Devonian sedimentary units folded into a large synclinorium. The Tachlovice Fault (Svoboda & Prantl 1948) is one of major longitudinal faults in the Prague Synform located in the NW limb of the synform. This fault at least fourty kilometers in length strikes in WSWENE direction and dips in 45 SE and could be traced from the surroundings of Beroun through Prague to Běchovice. The stratigraphic separation diagram for the Tachlovice Fault was constructed using detailed geological maps (1: 25 000). Based on the interpretation of SSD, we obtained an exact argument for the flat-and-ramp geometry of the Tachlovice Fault. The opposite sense of tectonic transport along this fault top-to-the SE ("normal" faulting) was documented by small-scale structures (small ramps, S-C structures etc.). These arguments shows that the Tachlovice Fault is a flat-and-ramp fault with large bedding-paralell flats reoriented due to folding to a "normal" fault position. |
