Název v původním jazyce

Deformation of Ordovician sedimentary rocks, Prague Synform, Barrandian, Czech Republic

Popis výsledku v původním jazyce

Sedimentary rocks in Prague Synform were significantly affected by deformation during variscan orogeny. The Silurian and Devonian rocks were intensely folded and thrusted (Melichar, 2003). Unfortunately, deformation of the Ordovician rocks is not visible. Due to observations of internal fabrics of rocks, anisotropy of magnetic susceptibility (AMS) study was extensively used. Different types of AMS fabrics were found in the investigated area. This study is focused on strain fabrics. Such fabrics are associated with different deformation episodes that affected the area. Essentially, there are two groups of strain fabrics related to different deformation scenarios in Prague Synform. These groups differ in the orientation of magnetic lineation in paleocoordinates (Figure). From that point of view, the AMS fabrics from the neighbour of Skřípel village are very important for understanding the complicated situation in Ordovician rocks.
